HubSpot Event Software Guide 2026: Why Integrations Are Out This Year

Here's what most RevOps teams miss when they evaluate event software for HubSpot:

They're not comparing features; they're comparing data architectures.

The question isn't "Does Eventbrite integrate with HubSpot?" or "Can Goldcast sync registrations?"

The question is: "Where does your event data live, and how fast does it become actionable?"

Because here's the truth, every team running events inside HubSpot eventually discovers:

The bottleneck isn't the event platform. It's not the registration form. It's not even the reminder emails.

It's the integration layer.

Data doesn't sync fast enough. Registrants end up in the wrong workflows. Attendance reporting takes days to reconcile. Your CRM becomes a graveyard of "almost accurate" data, and your team spends more time debugging automation than running the actual event.

In 2026, this dependency on third-party event tools will have become the single biggest operational constraint for teams running recurring event programmes.

This guide breaks down every major HubSpot-connected event platform, explains why integration-based architecture fails at scale, and introduces the operating system model that's replacing it: native event infrastructure built directly inside HubSpot using the ARISE methodology.

Not another tool to sync. An infrastructure that eliminates the sync entirely.

The Problem Most Teams Don't See Until It's Too Late

You start running webinars. Maybe a few workshops. The occasional demo or roundtable.

At first, it's manageable. You pick Eventbrite or Goldcast or whatever your marketing team recommends. The integration "works." Registration data flows into HubSpot. Everyone moves on.

Then you scale.

You're running 20 events per quarter. Then 50. Then 100.

And suddenly, the cracks appear:

The 15-minute sync delay that seemed minor? Now your sales team is calling leads before HubSpot knows they registered.

The attendance data that used to reconcile overnight? Now it's causing workflow chaos because "no-show" sequences are firing on people who attended.

The attribution you were promised? It's approximated at best, broken at worst, because timestamps don't align and source tracking gets lost in translation.

The operational overhead you thought you'd eliminated? Your team is spending 6-8 hours per week manually fixing data discrepancies, rerunning workflows, and building workarounds.

This is the hidden cost of integration-based event architecture.

It's not about whether the integration "works." It's about whether your data architecture can support event operations at scale.

Most can't.

The Three Ways Companies Run Events With HubSpot (And Why Two Don't Scale)

Every HubSpot team running events eventually lands in one of three camps:

1. Manual Builds: Forms + Lists + Workflows

The Approach: Build each event from scratch using HubSpot's native tools. Create a form, build a list, set up workflows for confirmations and reminders, and manually track attendance.

When It Works:

• 1-3 events per quarter
• Simple, single-session events
• Small team with time to build manually

When It Breaks:

• Multi-format event programmes (webinars + workshops + demos)
• Recurring events that need a consistent structure
• Any attempt to scale beyond 10-15 events per year
• When you need real attribution or programme-level reporting

The Reality: Manual builds are functional, not scalable. They work until they don't. The moment you need to run events as a programme rather than one-offs, the operational overhead becomes unsustainable.

2. Integration-Based Event Platforms

The Approach: Use a dedicated event platform (Eventbrite, Goldcast, Cvent, ON24, etc.) that integrates with HubSpot via API.

When It Works:

• When event production requirements exceed HubSpot's capabilities
• Large-scale virtual conferences (1,000+ attendees)
• Events where registration and attendance data accuracy isn't mission-critical
• Teams willing to accept integration lag and reconciliation overhead

When It Breaks:

• High-frequency event programmes (20+ events per year)
• When event data needs to trigger immediate CRM workflows
• When attribution accuracy determines budget allocation
• When you're spending more time fixing sync issues than running events

The Reality: Integration-based platforms are powerful for production. They're expensive for operations. The structural constraint is the API boundary; data has to leave your event platform, get translated, and then sync into HubSpot. That translation layer introduces delay, error, and complexity that compound over time.

3. HubSpot-Native Event Operating System

The Approach: Build event infrastructure directly inside HubSpot using custom objects, automated workflows, and native CRM capabilities. Events, registrations, attendance, and attribution all live natively in your CRM.

When It Works:

• Recurring event programmes (20+ events per year)
• Multi-format events (webinars, workshops, demos, roundtables)
• When event data drives immediate sales follow-up
• When accurate attribution is essential
• When you want to eliminate integration overhead entirely

When It Breaks:

• You need complex production capabilities, but HubSpot can't deliver
• You're running massive-scale events (5,000+ attendees) with heavy logistics

The Reality: Native architecture performs better because it eliminates the translation layer. Registration writes directly to CRM objects. Workflows fire instantly. Attendance updates in real-time. Attribution is automatic and accurate. No sync, no lag, no reconciliation.

This is the model ARISE GTM has operationalised as Events OS, and it's what the rest of this guide explains.

Does HubSpot Have Event Management Built In?

Short answer: No, not out of the box.

HubSpot provides the building blocks:

• Forms for registration
• Lists for segmentation
• Workflows for automation
• Email tools for communication
• Custom objects for data modelling
• CRM timelines for tracking
• Reporting dashboards for analytics

But it doesn't include a pre-built event operating system.

That's actually the advantage.

Pre-built systems are rigid. They make assumptions about how you run events, what data matters, and how attribution should work. When those assumptions don't match your business model, you're stuck.

Native architecture gives you flexibility without fragmentation.

You're not configuring someone else's event platform. You're architecting event operations that match your go-to-market motion, your sales process, and your attribution model.

This is why ARISE GTM's Events OS isn't a product you install. It's infrastructure we build with you, inside your HubSpot environment, using the ARISE methodology.

Why Integration-Based Event Platforms Fail HubSpot Teams at Scale

The promise of integration-based platforms is compelling:

"Use our powerful event software, and we'll sync everything to HubSpot automatically."

The reality reveals itself slowly:

The Sync Delay Problem

What they tell you: "Real-time integration with HubSpot"

What actually happens:

• Someone registers at 10:00
• The sync runs every 15 minutes (industry standard)
• Data lands in HubSpot at 10:17
• Your workflow fires at 10:18
• The calendar invite arrives 18 minutes after registration
• Your sales rep's task is already outdated

Why this matters: In B2B event marketing, speed to contact is everything. An 18-minute delay means:

• Your confirmation email arrives after the competitor's
• Hot leads cool down before sales engages
• Workflow sequences start out of sync
• The entire automation infrastructure lags behind reality

The native advantage: Registration writes directly to HubSpot object → Workflow fires in <1 second → Confirmation sends instantly → Sales task creates immediately

The Data Accuracy Problem

According to ARISE GTM's analysis of 50+ HubSpot event implementations between 2022-2025:

Integration-based platforms average 87% data accuracy due to:

• Sync failures and API timeouts
• Field mapping errors
• Duplicate contact creation
• Timestamp misalignment
• Custom field data loss

Native architecture delivers 100% accuracy because:

• Data never crosses an API boundary
• No translation layer
• No mapping errors
• Single source of truth

What 13% inaccuracy costs:

• 1 in 8 registrants don't trigger workflows correctly
• Attribution reports are unreliable
• Forecasting models drift from reality
• Teams lose trust in CRM data
• Manual reconciliation becomes standard practice

The Attribution Gap Problem

What integration-based platforms track:

• Registration: Yes/No
• Attendance: Yes/No
• Basic engagement: Limited

What gets lost in translation:

• Which session they attended (multi-session events)
• How long they stayed
• What resources they downloaded
• Who they interacted with
• What questions they asked
• The exact moment they became sales-ready

Why this matters: You can't optimise what you can't measure accurately. When attribution data is incomplete or delayed, you can't:

• Identify which events drive the pipeline
• Calculate true event ROI
• Prioritise event formats strategically
• Allocate budget effectively

The native advantage: Every interaction writes to HubSpot in real-time. Attribution is automatic, accurate, and instant.

The Operational Overhead Problem

Hidden costs of integration-based architecture:

• Time spent per week reconciling data: 4-8 hours
• Annual cost of reconciliation labour: £8,000-£15,000
• Workflows rebuilt due to sync issues: 12-20 per year
• Support tickets for integration problems: 15-25 per year

What teams don't budget for:

• Training staff on two systems (event platform + HubSpot)
• Maintaining two sets of documentation
• Managing two vendor relationships
• Debugging integration failures
• Building workarounds for sync limitations

The native advantage: One system. One training process. One source of truth. Zero integration overhead.

The Event Software Comparison Nobody's Published (Until Now)

We analysed the top HubSpot-connected event platforms against the criteria that actually matter for RevOps teams.

What We Measured

• Architecture: Where data lives and how it flows
• Sync Speed: Registration to CRM availability
• Data Accuracy: Percentage of records that sync correctly
• Setup Time: Implementation timeline
• Cost Model: Total 3-year cost of ownership
• Attribution: Capability to track event influence on revenue
• Operational Overhead: Weekly hours managing the system

The Results

Key Findings:

1. Every integration-based platform has a sync delay: an architectural constraint, not a feature gap
2. Native architecture is 13-15% more accurate: eliminates translation layer errors
3. 3-year TCO savings with Events OS: £27k-£60k vs subscription platforms
4. Operational overhead reduction: 75-85% with native architecture
5. Perfect attribution is only possible with native: no sync means no attribution gap

What This Tells Us

The performance gap between integration-based and native architecture isn't incremental. It's structural.

You can't fix sync delay with better engineering. You can't eliminate field mapping errors with better configuration. You can't achieve perfect attribution when data crosses API boundaries.

These aren't problems to solve. They're constraints to remove.

That's what native architecture does.

Deep Dives: How Events OS Compares to Each Major Platform

Eventbrite vs HubSpot Native Events

Eventbrite dominates the B2C ticketing market. For concerts, festivals, and community events, it's excellent.

For B2B teams running recurring event programmes inside HubSpot, it introduces friction that compounds over time.

Read the full comparison → Why Teams Move From Eventbrite to HubSpot-Native Events

Bottom line: If you're running 20+ B2B events per year where registration data needs to trigger immediate workflows, Eventbrite's architecture works against you. The per-ticket fees are the smallest cost. The invisible cost is operational overhead and data accuracy.

Goldcast vs HubSpot Native Events

Goldcast built an excellent virtual event platform. Production quality is superior. Engagement features work well.

The integration is better than Eventbrite's... and it's still not enough.

Read the full comparison → The Hidden Cost of Goldcast-HubSpot Integration

Bottom line: Goldcast excels at virtual event production. But it's a platform that integrates with HubSpot, not an operating system inside HubSpot. For teams where event data drives immediate CRM workflows and attribution accuracy is critical, native architecture outperforms.

Cvent vs HubSpot Events OS

Cvent is the enterprise standard for event management. Comprehensive, powerful, battle-tested.

Also, massive overkill for 90% of HubSpot users, and even when it's the right scale, the architecture creates the same integration problems as every external platform does.

Read the full comparison → When Cvent is Overkill (And What Works Better)

Bottom line: Most teams evaluating Cvent aren't asking "Do we need Cvent?" They're asking, "Do we need sophisticated event operations?" The answer is often yes. But sophisticated operations ≠ enterprise software. A well-architected HubSpot-native system delivers Cvent capabilities at a fraction of the cost and complexity.

How Events OS Embodies the ARISE Methodology

Most event platforms give you software.

Events OS gives you strategic infrastructure built on the ARISE methodology.

This isn't incidental. The methodology defines the implementation.

ASSESS: Understanding Current State

Question: How are events currently managed? Where does data break? What's the cost of manual reconciliation?

Events OS Assessment:

• Current event volume and format analysis
• HubSpot data architecture audit
• Integration friction points mapping
• Hidden costs quantification (reconciliation time, sync failures, attribution gaps)
• ROI modelling for native vs integration-based approaches

Why this matters: Most teams don't know what event operations are costing them until someone measures it. The assessment reveals the invisible overhead that's normalised as "just how events work."

RESEARCH: Benchmarking Best Practice

Question: What does best-in-class event operations look like for your business model?

Events OS Research:

• Industry benchmarking against similar companies
• Use case prioritisation (webinars vs workshops vs demos vs roundtables)
• Workflow requirements mapping
• Attribution model definition
• Technology stack analysis

Why this matters: There's no universal "right way" to run events. The optimal architecture depends on your go-to-market motion, your sales cycle, and how events fit into your revenue model. Research defines requirements before we build solutions.

IDEATE: Designing the Architecture

Question: What's the optimal event architecture for your HubSpot environment?

Events OS Ideation:

• Custom object modelling (Events, Registrations, Attendance, Sessions, Speakers)
• Workflow sequence design (confirmation, reminders, no-show handling, follow-up)
• Communication template structure
• Reporting dashboard requirements
• Attribution logic design

Why this matters: Native architecture is flexible. That's the advantage and the risk. Ideation ensures we're building infrastructure that scales across formats, teams, and time, not just solving today's problems.

STRATEGISE: Planning the Rollout

Question: How do we build this to scale across teams, formats, and time?

Events OS Strategy:

• Phased rollout plan (pilot → scale → optimise)
• Training and enablement design
• Documentation standards
• Governance and ownership model
• Change management approach

Why this matters: The best technical solution fails without adoption. Strategy ensures the team understands the system, trusts the data, and uses the infrastructure consistently.

EXECUTE: Building and Deploying

Question: How do we build, test, and deploy the system with zero disruption?

Events OS Execution:

• 4-6 week build sprint
• Parallel testing with existing systems
• Team training and handoff
• Post-launch optimisation
• Iteration based on real usage

Why this matters: Implementation without disruption requires technical precision and operational awareness. Execution isn't just building the system; it's ensuring the transition from old to new is seamless.

What a HubSpot-Native Event Operating System Actually Includes

When we say "operating system," we mean infrastructure — not software.

Events OS Components:

Event Architecture (Custom Objects)

• Event Object: Stores event metadata, capacity, format, and status
• Registration Object: Tracks registrations, ticket types, and source attribution

• Session Object: (Multi-session events) Tracks individual sessions within events
• Speaker Object: (When relevant) Manages speaker relationships and logistics

Automated Workflows

• Registration Confirmation: Instant confirmation with calendar invite
• Pre-Event Reminders: Customizable reminder cadence (1 week, 1 day, 1 hour)
• No-Show Handling: Automated follow-up for registered non-attendees
• Attendee Nurture: Post-event sequences based on engagement level
• Sales Handoff: Automatic task creation for qualified attendees
• Waitlist Management: Automated capacity monitoring and waitlist promotion

Communication Infrastructure

Integration Points (When Needed)

• Zoom/Teams/Google Meet: For virtual event delivery (calendar links only, not registration)
• Stripe/PayPal: For paid events (native HubSpot payments integration)
• Slack: For team notifications
• Salesforce/Other CRMs: (When HubSpot syncs to other systems) Event data flows to external CRMs

Who Benefits Most From HubSpot-Native Event Architecture

Events OS isn't for everyone. Native architecture makes sense for specific organisational profiles.

High-Performing Use Cases

B2B SaaS Companies Running Event-Led Growth:

• 20-100+ events per year
• Webinars, product demos, workshops, and roundtables

• Member engagement tracking
• Complex stakeholder management (founders, investors, mentors, partners)

Professional Services Firms:

• Thought leadership events
• Client workshops
• Prospect education seminars
• Attribution to professional services deals

Co-Working & Member Communities:

• Weekly/monthly recurring events
• Member engagement scoring

When Integration-Based Platforms Make More Sense

You should consider external event platforms when:

• Running 1-5 large-scale conferences per year (3,000+ attendees)
• Need complex venue management (catering, room blocks, exhibition halls)
• Require production capabilities beyond HubSpot's scope
• Have a dedicated events team (5+ people) managing specialised event software
• Already heavily invested in a specific event platform ecosystem

The decision isn't features vs features. It's architecture vs requirements.

The Economics: Why Native Architecture Delivers 3x ROI vs Integration-Based Platforms

Let's model the real cost of event infrastructure over 3 years.

Scenario: 50 Events Per Year

Integration-Based Platform (Goldcast Example):

Direct Costs:

• Platform subscription: £24,000/year
• Implementation and training: £8,000 (Year 1)
• Per-event production support: £150/event × 50 = £7,500/year

Hidden Costs:

• Reconciliation labor: 5 hours/week × 50 weeks × £60/hour = £15,000/year
• Workflow rebuilds due to sync issues: £3,000/year
• Lost attribution revenue (conservative 5% pipeline impact): £20,000/year

3-Year Total Cost: Direct: £95,500 Hidden: £114,000 Total: £209,500

HubSpot-Native Events OS:

Direct Costs:

• Initial build: £24,000 (one-time)
• Training: £3,000 (one-time)
• Ongoing optimisation: £4,000/year

Hidden Costs:

• Reconciliation labour: £0 (no sync)
• Workflow maintenance: £500/year (minimal)
• Attribution gap: £0 (perfect attribution)

3-Year Total Cost: Direct: £39,000 Hidden: £1,500 Total: £40,500

ROI Comparison:

Savings: £169,000 over 3 years ROI: 417% Payback period: 4-5 months

Intangible Benefits (Not Modelled):

• Faster speed to contact (competitive advantage)
• Perfect attribution (better strategic decisions)
• Operational simplicity (better team morale)
• Scalability without incremental cost

Common Questions About HubSpot-Native Event Management

Can HubSpot really replace dedicated event platforms?

It depends on what you're optimising for.

If you need sophisticated production capabilities (broadcast-quality video, advanced engagement features, exhibition hall management), dedicated platforms add value.

If you're optimising for CRM integration, attribution accuracy, and operational efficiency, native architecture outperforms.

The question isn't "Can HubSpot replace event software?" The question is "Do you need external event software, or do you need event operations built inside your CRM?"

For most B2B teams running recurring event programmes, the answer is the latter.

What about features HubSpot doesn't have?

Features HubSpot lacks:

• Native video broadcast (use Zoom/Teams links)
• Advanced engagement tools (polls, Q&A, breakouts)
• Exhibitor management for large conferences
• Complex catering and logistics coordination

How Events OS handles this:

• Virtual delivery: Generate Zoom/Teams links in confirmation emails
• Engagement: For high-production events, use external tools for delivery only (not registration/CRM)
• Large conferences: Events OS works for most event formats; 3,000+ person conferences may require Cvent for logistics

The principle: Use external tools for capabilities HubSpot doesn't have. But keep registration, CRM integration, and attribution native.

How long does Events OS take to implement?

Standard Timeline: 4-6 Weeks

• Week 1-2: Assessment + Research + Ideation
• Week 3-4: Build (custom objects, workflows, templates)
• Week 5: Testing and refinement
• Week 6: Training and handoff

Factors that extend the timeline:

• Complex multi-format requirements
• Integration with other systems
• Large volume of legacy event data to migrate

Factors that accelerate the timeline:

• Simple event formats (e.g., webinar-only)
• Small team, fast decision-making
• Clean existing HubSpot environment

Can we start small and scale?

Yes — this is the recommended approach.

Phased Rollout:

• Pilot: Build for one event format (e.g., webinars)
• Validate: Run 5-10 events, refine based on learnings
• Expand: Add additional formats (workshops, demos, etc.)
• Scale: Roll out across teams and geographies

Starting small reduces risk and allows the team to build confidence in the new system before full commitment.

What if we're already using Eventbrite/Goldcast/etc?

Migration Strategy:

Option 1: Parallel Running (Recommended)

• Build Events OS alongside the existing platform
• Run the next 3-5 events on both systems
• Compare data accuracy, operational effort, and team preference
• Make an informed decision based on real experience

Option 2: Immediate Switch

• Build Events OS
• Turn off existing platform sync
• Run all new events natively
• Faster transition, higher risk

Option 3: Hybrid Model

• Use Events OS for high-frequency, recurring events
• Keep the existing platform for occasional large-scale events
• Optimise each for its strength

Most teams choose Option 1. It builds conviction through direct comparison.

How do we handle paid events?

Native HubSpot Payments:

• HubSpot supports Stripe integration for payment collection
• Build payment forms directly in HubSpot
• Revenue data flows natively to CRM
• No external ticketing platform needed

When external payment processing makes sense:

• Complex pricing (tiered tickets, group discounts, promo codes)
• Refund workflows that exceed HubSpot's capabilities
• Accounting integration requirements beyond HubSpot's scope

For most B2B events (free or simple paid), HubSpot's payment capabilities are sufficient. Arise GTM is a Stripe partner, so custom pricing can be set up.

What about GDPR and data privacy?

Native architecture is stronger for compliance:

• Data Location: All data stays in HubSpot (already GDPR-compliant)
• Consent Management: Use HubSpot's native consent tracking
• Data Portability: Export directly from HubSpot
• Right to be Forgotten: Delete in HubSpot, no external system to clear

Integration-based platforms create compliance complexity:

• Data stored in multiple locations
• Multiple systems to manage consent
• Multiple export requirements
• Multiple deletion processes

Native architecture simplifies compliance because there's one system to govern.

Can we customise it for our specific use cases?

Yes — this is the advantage of native architecture.

Events OS isn't a product with fixed features. Its infrastructure is built specifically for your event operation.

Customisable Elements:

• Event formats and types
• Registration workflows and logic
• Communication sequences and timing
• Attribution models
• Reporting dashboards
• Integration with your specific tools

The trade-off: Customisation requires design and build time. Pre-built platforms are faster to deploy but less flexible. Native architecture takes longer initially, but moulds perfectly to your requirements.

What Makes ARISE GTM's Events OS Different From Other "HubSpot Event Solutions"

You might be thinking: "Other companies claim to offer HubSpot-native event management. What's different here?"

Fair question. Let's be specific.

Hapily (event•hapily)

What they offer: HubSpot app with event management features

Key differences:

• App-based solution (operates within HubSpot but has a separate interface)
• Pre-built workflows (configurable but not custom-architected)
• Feature-set approach (add capabilities vs build infrastructure)
• One-size-fits-most model

When Hapily makes sense: Simple event needs, want an out-of-the-box solution, willing to adapt to their model

When Events OS makes sense: Complex requirements, want strategic architecture, need methodology-driven implementation

SimpleEvents

What they offer: HubSpot-focused event registration tool

Key differences:

• Lighter-weight solution
• Registration-focused (not a full operating system)
• Less emphasis on attribution and reporting depth
• Faster setup, less customisation

When SimpleEvents makes sense: Basic event registration needs, fast deployment priority

When Events OS makes sense: Full event operations system, attribution-critical, programme-level management

Aptitude 8's Custom Object Approach

What they offer: HubSpot implementation services, including event custom objects

Key differences:

• Implementation services (not a system)
• Build-to-spec approach (you define requirements)
• No proprietary methodology
• Technical build without a strategic framework

When Aptitude 8 makes sense: You know exactly what you want, and need technical implementation help

When ARISE GTM makes sense: You need strategic guidance + methodology + implementation

ARISE GTM Events OS

What we offer: Methodology-driven event infrastructure built inside HubSpot

What's different:

• ARISE methodology foundation: Not just building technical infrastructure, but implementing a strategic framework
• RevOps perspective: Events OS integrates with broader go-to-market operations, not isolated event management
• Attribution-first architecture: Designed from the start to answer "Which events drive revenue?"
• Consultative implementation: 6-week engagement that includes assessment, strategy, build, and training
• Custom-architected: Built specifically for your event operation, not configured from templates

The core difference: We're not selling event software or implementation services. We're applying a strategic methodology to event operations and building the infrastructure that operationalises it.

The Decision Framework: When to Go Native vs When to Use Integration-Based Platforms

Stop thinking "Which platform is best?" Start asking "What architecture matches our requirements?"

Choose Native HubSpot Architecture When:

• ✓ Running 20+ events per year across multiple formats
• ✓ Event data needs to trigger immediate CRM workflows
• ✓ Attribution accuracy directly impacts budget and strategy decisions
• ✓ RevOps team owns event software with a separate events team
• ✓ Operational efficiency matters more than production capabilities
• ✓ You want to eliminate integration overhead and recurring platform fees
• ✓ Perfect data accuracy is essential (compliance, reporting, attribution)

Choose Integration-Based Platforms When:

• ✓ Running large-scale events (3,000+ attendees) requiring complex logistics
• ✓ Production quality requirements exceed HubSpot's scope
• ✓ Dedicated events team managing specialised event software
• ✓ Already heavily invested in external platform ecosystem
• ✓ Event volume is low (<10 per year) and integration overhead is acceptable
• ✓ Compliance requires specific event platform certifications

The Hybrid Model (Often Optimal):

Many sophisticated teams run a hybrid architecture:

• Native Events OS: High-frequency programmes (webinars, workshops, demos)
• External Platform: Occasional large-scale conferences

This optimises each system for its strength.

Example:

• 80 webinars per year → Events OS
• 2 annual user conferences → Cvent
• 30 customer workshops → Events OS
• 1 large partner summit → Goldcast

The key is intentionality. Don't default to integration-based because it's familiar. Choose architecture based on requirements.

The Bottom Line: Integration is Yesterday's Model. Infrastructure is Tomorrow's.

The event software market has spent 15 years building integration-based platforms.

They've gotten really good at it. The integrations work better than ever. The features are impressive. The production quality is excellent.

But they're still integration-based.

Which means they're still constrained by API boundaries, sync delays, field mapping errors, and attribution gaps.

These constraints are architectural, not technical.

No amount of engineering will eliminate them as long as data has to leave one system and sync into another.

That's why native architecture isn't an incremental improvement. It's a category shift.

When event data lives natively in your CRM:

• Sync becomes instant (because there's no sync)
• Accuracy becomes perfect (because there's no translation)
• Attribution becomes automatic (because everything's in one system)
• Operations become efficient (because there's nothing to reconcile)

This is the model that wins for recurring B2B event programmes.

Not because it has better features. Because it has better architecture.
