Hapily vs ARISE Events OS: Which HubSpot Event Solution Wins in 2026?

Why this comparison matters in 2026

If you're researching Hapily, you've probably already tried Eventbrite, Goldcast, or manual HubSpot forms — and hit the same wall: event data that lives outside HubSpot is data you can't trust for attribution.

TL;DR: Hapily and ARISE Events OS are architecturally similar — both deploy native HubSpot custom objects so event data lives in your portal, not an external platform. They diverge in three places that matter:

• Events OS does the money (automatic four-layer pipeline attribution on every event; Hapily requires manual workflow configuration),

• it learns (AI generates events in under two minutes, scores no-shows, suggests meetings, produces post-event narratives; Hapily has none of this), and

• it benchmarks (cross-event and Event Series intelligence that compounds; Hapily reports per-event only)

Hapily's one clear advantage: a packaged CMS theme for landing pages. Events OS starts at £3,495/year on HubSpot Professional+, unlimited registrations. Hapily starts at $7,499/year for 2,000 credits on Enterprise only. For most B2B teams running events for pipeline, Events OS is the answer. 

Hapily was the first credible answer to that problem. It deploys custom objects inside your HubSpot portal instead of syncing from an external platform. For teams moving off Eventbrite or Cvent, it was a meaningful upgrade.

But "native storage" is not the same as "native revenue intelligence." And that's the gap ARISE Events OS closes.

This guide is specific about where the two products differ, using product data current as of April 2026 — Events OS's launch window as a packaged HubSpot application.

According to ARISE GTM analysis of 50+ B2B event programme implementations, the choice between Hapily and Events OS comes down to three questions:

1. Do you need your event infrastructure to prove pipeline, or just manage registration?
2. Do you want AI doing the setup, scoring, and follow-up — or a team doing it manually?
3. Does every event you run need to make the next one smarter?

This guide answers those three questions with product specifics.

What Hapily actually is

Hapily is a HubSpot marketplace app that deploys custom objects into your HubSpot account — Event, Session, Registrant, Ticket, Speaker. It adds a management UI, CMS theme modules, QR check-in, and workflow actions on top.

Hapily's strengths are real: a packaged CMS theme, reliable QR scanning, and a product team with deep HubSpot familiarity. If you're on Eventbrite and need something better, Hapily is a genuine upgrade.

Pricing: Hapily starts at approximately $7,499/year for 2,000 registration credits and scales to $14,999/year at higher tiers. Hapily requires HubSpot Enterprise for full functionality.

What ARISE Events OS is

ARISE Events OS is a HubSpot-native AI-powered event intelligence product — installed via OAuth in three minutes, running on HubSpot Professional or above, priced as an annual subscription with three tiers:

• Starter — £3,495/year — AI event setup, factory builds all assets in 2 minutes, post-event AI narrative, pipeline attribution (four layers), RSVP + QR check-in, portfolio dashboard, 500 agent runs/month.
• Growth — £6,995/year — everything in Starter, plus no-show risk scoring, Deal Room, Command Centre, waitlist AI recommendations, cross-event benchmarks, audience breakdowns.
• Scale — £11,995/year — everything in Growth, plus invite recommendations (AI scans CRM and ranks by deal value), contact intelligence card on every HubSpot contact record, Event Series intelligence, meeting agent (AI-suggested meetings per attendee), advanced fit scoring, priority support.

Unlimited registrations at every tier. No per-attendee fees. Fourteen-day free trial on Starter with no credit card required.

Where the two products are architecturally similar: both deploy custom objects into your HubSpot portal. Event, Registration, Attendance and related records live natively in HubSpot in both cases. Data structure is broadly equivalent.

Where they differ architecturally: Hapily manages events through its own app-layer UI. Events OS manages events entirely inside HubSpot's CRM — an agentic UI card embedded on native HubSpot records, plus workflow and dashboard views. There's no separate app UI to learn. Your team works where they already work.

What each product does with the shared native foundation is where the comparison actually lives.

The three things Events OS does that Hapily doesn't

1. It does the money

Hapily manages events. Events OS proves pipeline.

Hapily gives you the building blocks — custom objects, workflow actions, CMS modules — to track attribution. You build the attribution yourself. You create calculated fields, associate deals, configure workflows. It works, but it's manual and it's only as good as the configuration.

Events OS runs four-layer attribution automatically on every event completion. Registration → Contact → Company → Deal, mapped without any manual workflow configuration or tagging. Pipeline influenced by each event is calculated, rolled up, and surfaced in your portfolio dashboard the morning after the event.

This is what we mean when we say Events OS "does the money." When the CFO asks what pipeline the Q3 customer roundtable generated, you don't pull a spreadsheet. You open HubSpot and read the number.

2. It learns

Hapily is a static tool. You configure it once and it does the same thing forever. Good workflows stay good. Bad configurations stay bad. The product doesn't get smarter the more you use it.

Events OS is AI-native. Specific behaviours your team would otherwise do manually:

• AI event setup. Describe your event in plain English. Registration form, landing page, email sequences, reminder workflows, and capacity management — all built in under two minutes. Included on Starter and above.
• No-show risk scoring. Before the event fires, Events OS scores every registrant on four signals: registration recency, previous no-show history, RSVP status, and lifecycle stage. You act before they don't show up. Included on Growth and above.
• Invite recommendations. Before the next event, the AI scans your entire CRM and returns a ranked invite list — scored by deal value, lifecycle stage, and event history. Not guesswork. Included on Scale.
• Post-event AI narrative. After every event, Events OS generates a written summary of what happened, who mattered, and what the sales team should do next. Included on every tier.
• Meeting agent. After an event, AI evaluates each checked-in attendee and suggests a meeting with the right HubSpot Meetings link. Suggestion-only or auto-invite mode. Included on Scale.

Hapily has none of this. You can't retrofit it either — the product's architecture doesn't learn.

3. It benchmarks

This is the feature that compounds over time and is the single biggest reason teams move from Hapily to Events OS after 12–18 months.

Hapily reports per-event. Each event's data is available, but there's no structural view of how this webinar compared to the last ten, or how your workshop series compares to your field events, or which event formats drive the highest deal velocity.

Events OS ships cross-event benchmarks on the Growth tier and Event Series intelligence on Scale. As you run events, the product learns patterns across your portfolio: which formats drive the most pipeline, which personas show up, which topics correlate with opportunity creation. By event number thirty, you're running a smarter programme than you could design from scratch.

Hapily doesn't have a benchmark layer. Every event starts from zero.

Architecture comparison: the common ground

To be fair: where Hapily and Events OS are architecturally similar matters. Both avoid the problems of integration-based platforms (Eventbrite, Goldcast, Cvent):

So the basic attribution plumbing works in both. The difference is everything that happens after the plumbing.

Feature comparison: where each platform wins

An honest trade-off: Hapily ships a packaged CMS theme for event landing and registration pages out of the box. Events OS does not currently include a page builder — teams either bring their own HubSpot CMS pages, use HubSpot's native forms on existing pages, or use third-party registration pages that post to HubSpot.

For teams that value a packaged page-builder experience, Hapily has an advantage here. For teams that already have a branded HubSpot CMS or want to control page design themselves, it's a non-issue. 

Cost comparison: unlimited vs credit-based

The two products price fundamentally differently, which makes a like-for-like tier comparison misleading. Here's the honest picture.

Hapily — credit-based pricing. Starts at $7,499/year for 2,000 registration credits (one credit per registrant). Scales up to $14,999/year at higher credit volumes. If you run a large event or a high-frequency programme, credits deplete and the price climbs. Requires HubSpot Enterprise.

ARISE Events OS — flat annual subscription with unlimited registrations at every tier. Starter £3,495/year, Growth £6,995/year, Scale £11,995/year. No per-attendee fees, no credits, no caps on event volume. Runs on HubSpot Professional or above.

What this means in practice. A team running 10 events × 200 attendees/year = 2,000 registrants — exactly Hapily's entry-tier cap. Any growth beyond that and you're negotiating into the $14,999 tier. Events OS handles 2,000 or 20,000 registrants on the same £3,495 Starter subscription with zero pricing impact.

The ARISE Events OS product page puts it bluntly: "hapily starts at $7,499/year for 2,000 credits. We start at £3,495/year for unlimited." That's a roughly £2,400 annual saving at entry level, and the gap widens as event volume grows.

The subscription savings are real, but the bigger point is what you get for the money: Events OS's AI capabilities (event setup, no-show scoring, post-event narrative, invite recommendations, meeting agent) aren't features Hapily offers at any price.

When to choose Hapily

Hapily is the right call when:

• You're already on HubSpot Enterprise and want a packaged marketplace app experience
• You need the packaged CMS theme and don't want AI-built assets
• Manual attribution workflows are fine for your reporting needs
• You don't need AI-assisted setup, scoring, invites, or post-event follow-up
• You're running fewer than 15 events a year and benchmarking won't compound much value

When to choose ARISE Events OS

Events OS is the right call when:

• You want automatic pipeline attribution (not manual configuration)
• AI-driven setup and follow-up would save your team meaningful time
• You run 20+ events a year and cross-event benchmarking would make the programme smarter
• You're on HubSpot Professional and don't want to upgrade to Enterprise just for events
• You need the Deal Room and ranked call list for sales to act the morning after
• You want unlimited registrations without per-attendee credit accounting

The migration question

If you're already on Hapily and considering moving to Events OS: good news — the data architecture is similar (both use HubSpot custom objects), so migration is mostly about moving configuration and workflows, not re-platforming data.

Typical timeline: 1–2 weeks.

1. Install Events OS via OAuth (3 minutes)
2. Map Hapily objects to Events OS objects
3. Migrate active workflows and page templates
4. Run parallel on one event cycle
5. Cut over, uninstall Hapily

The bottom line

Hapily is a good product. It solved the right problem in 2022 — getting B2B event data out of external platforms and into HubSpot. If you're still on Eventbrite or Cvent, Hapily would be an upgrade.

But the problem has moved on. In 2026, storing data natively in HubSpot is table stakes. The interesting question is what your event infrastructure does with the data: does it prove pipeline, does it learn, does it compound across events?

Events OS answers yes, yes, yes. Hapily answers no, no, no.

For most B2B teams running more than fifteen events a year, the comparison isn't close. For teams running fewer events, the decision comes down to whether AI-driven setup and attribution are worth the switch — and given Events OS starts roughly £2,400 cheaper than Hapily at entry tier and doesn't cap registrations by credit, it usually is.

Either way, know what you're buying — storage or intelligence — and price the decision accordingly.

Frequently asked questions

Is Hapily a native HubSpot solution?

Yes — Hapily deploys custom objects directly into HubSpot and stores event data in your portal. It's not an integration platform with sync delays. The caveat: Hapily manages data natively but doesn't turn that data into pipeline attribution, AI-driven intelligence, or cross-event benchmarks. Events OS adds those layers on top of the same native foundation.

What's the key difference between Hapily and ARISE Events OS?

Both deliver native HubSpot custom objects. The difference is what happens after registration. Hapily manages events. Events OS does three things Hapily doesn't: automatic four-layer pipeline attribution (the money), AI-driven setup and follow-up (it learns), and cross-event benchmarking (it compounds). Hapily is static; Events OS gets smarter as you run more events.

How much does Hapily cost compared to ARISE Events OS?

Hapily starts at $7,499/year (≈£5,900) for 2,000 registration credits, scaling to $14,999/year at higher credit volumes — costs rise with event volume because pricing is credit-based (one credit per registrant).

ARISE Events OS starts at £3,495/year (Starter), £6,995/year (Growth), or £11,995/year (Scale) — with unlimited registrations at every tier, no per-attendee fees, and no credit caps. Events OS is cheaper at entry and top tiers and doesn't scale costs with event volume.

Does Hapily require HubSpot Enterprise?

Yes — full Hapily functionality requires HubSpot Enterprise. ARISE Events OS runs on HubSpot Professional or above, which means teams on Professional don't have to upgrade their HubSpot tier to get event intelligence.

Can I migrate from Hapily to ARISE Events OS?

Yes, and it's the simplest migration in the event platform category. Because Hapily's data is already in HubSpot custom objects, migration is mostly about moving configuration and workflows. Typical timeline: 1–2 weeks. Events OS installs via OAuth in three minutes; data mapping and workflow migration take the rest. See our Hapily to Events OS migration guide.

Which is better for event attribution?

Events OS by design. Hapily supports attribution but requires you to configure it — build calculated fields, associate deals, create workflows. Events OS runs four-layer attribution (Registration → Contact → Company → Deal) automatically on every event completion with zero configuration. When the CFO asks what pipeline an event generated, Events OS answers from the dashboard; Hapily answers from a custom report you built.

Does Hapily have AI features?

Not as of April 2026. Hapily manages events; it doesn't include AI for event setup, no-show scoring, invite recommendations, meeting suggestions, or post-event narrative generation. Events OS includes all of these across its three tiers.

Is ARISE Events OS suitable for small event programmes?

Yes — Events OS Starter (£3,495/year) is designed for teams running fewer events where unlimited registrations and AI-driven setup still justify the spend over manual tools. For teams running fewer than five events per year, the ROI case is weaker; for fifteen or more events per year, Events OS pays for itself quickly through operational time savings and improved attribution.

Can I try ARISE Events OS before committing?

Yes — Events OS Starter includes a 14-day free trial with no credit card required. Install via OAuth in three minutes.
