For ten years, Brella's engines have computed personal attention at events — matched meetings, schedules that work — inside our app. Now they're yours to build on: a solid, event-focused foundation for your own apps, dashboards, kiosks and agents. Design any event experience you can imagine — and keep full ownership of your data, wired into the stack you already run and free to use anywhere you need it. You ship the experience. We run the hard parts.
Your surface, our rails · Insights API · MCP 2.0 · Workbench
Attendees, exhibitors and sponsors want more than to be known — they want tools that work for them and results worth paying for, everywhere the event touches them: before the show, on the floor, in the report afterwards. One app screen can't carry that. The purpose-built event technology behind it can.
The personal touch lived in one surface — the networking screens of an event app. Every other touchpoint ran on generic: static agendas, aggregate reports, PDF sponsor decks.
of exhibitors churn every year. Replacing one costs about five times keeping one.
UFI / Exploriof attendees never find the vendors they travelled to meet — and only 11% of organizers noticed.
Freeman 2025of exhibitors can't say whether a single lead converted. They won't keep renewing what they can't measure.
IntegrateThat's what generic costs. And delivering the personal version on every surface runs into two walls — one made of software, one made of people.
AI didn't just democratize development — it democratized creativity. Anyone can realize their own idea now and get the pretty 70% in a weekend, for a few thousand in tokens. The other 30% is the foundation it has to run on — the decade of hard parts below. See who carries what:
a sprint at AI speed — this part was never the problem
months of hardening after the demo works
€15–30K per pen test, app-store approvals — on you
one mistake costs more than the system
learns at your attendees' expense
the 6 a.m. pager is yours
a retained developer, indefinitely
The pretty part is genuinely cheap. These six are what it actually costs — and if one of them fumbles live, the loss isn't the build budget. It's trust.
"An event app gets four days to shine — and a year of upkeep."Build the experience in a sprint. Leave the other 361 days to us.
At a few hundred attendees, a sharp team of ten can run personal attention by hand — plenty of our customers do, every year. In the thousands, the arithmetic turns: recruit the buyers, plan hundreds of committed meetings, run them on-site, absorb every reschedule, reconcile which meetings happened and what they were worth. Drag the slider and watch it turn:
expect personalized navigation to the right exhibitors (43%)
expect proactive introductions matched to their goals (41%)
expect to be matched with the right other attendees (36%)
possible pairings to evaluate at this size. It's not a diligence problem — it's arithmetic.
"I want the systems to do 80% of the work — and then I want to go in and finesse the last 20%. Because I really know what good looks like."

The industry's own research measured what actually stops organizers — and it isn't vision. It's operations. Every one of these barriers is a thing we take off your plate. Flip them.
The #1 barrier — bigger than cost. The tools exist; the team to run them doesn't.
Flip →The engines arrive already working — shaped by millions of real meetings — and our team operates them. Your staff's job on show day doesn't change.
← BackNew platform, new headcount, new line items nobody budgeted for.
Flip →Usually less than one retained developer. You pay when the engine works — per profile matched, per meeting orchestrated. A number that fits next year's budget.
← BackPersonalization runs on personal data. One GDPR mistake costs more than the system.
Flip →Consent travels with every data point. Full audit trail, EU hosting, DPAs ready. We don't train on your data — your events improve your events, nobody else's.
← BackRegistration, app, scanners, CRM — bought separately, connected never.
Flip →Workbench connects Cvent, Stova, Swoogo, HubSpot, Salesforce two-way — registrations in, leads and attribution out. Connection, not migration.

Removing those four barriers is a job description. It's ours. Here's what you actually get.
Not "a platform" — specific pieces your team can pick up on day one: the Insights API, MCP 2.0 for agents, and Workbench for the stack you already run. Direct, easy, agent-safe access to the systems we've run for a decade. Click through the stack:
apps · dashboards · kiosks · chatbots · sponsor tools · agents
Insights API · MCP 2.0 · Workbench
event database · matchmaking · meetings · Pulse
access keys · consent · audit · EU
The Insights API — read/write over 28 resource types, with webhooks and SDKs. Everything an event is, queryable and buildable-on.
MCP 2.0 — the connection AI agents speak natively. Agents propose, people approve, everything is logged.
Workbench — managed two-way connectors for Cvent, Stova, Swoogo, HubSpot and Salesforce, with a ledger of every record that moves.
Every one of these runs on the same backend, through an access key that opens exactly what it needs — nothing else reachable. Build at AI speed, iterate even faster — and be production-ready in days, not weeks or months.
Build a sponsor dashboard: each sponsor sees their booked meetings, scans and pipeline — live.
Describe the build — your developer, your agency, or an AI agent does the rest. Keystone provides the pieces: a tightly scoped access key, the Insights API, live webhooks. The pretty part was never the hard part. The hard part is ours.
The exact view each sponsor keeps asking for — live, not in week three. Build a one-page web app, or point Looker or Sheets at the key. Same data powers your internal portfolio dashboards.
Build my Tuesday — payments sessions, two meetings with infra vendors, nothing before ten.

Find three high-intent buyers · propose Tuesday meetings.
Nothing to build — this is a connection, not a project. Attendees and sponsors point the assistant they already use at your event over MCP 2.0. Each agent sees only its key's world; writes arrive as drafts people approve. The first event infrastructure agents can book on — and something your event can advertise.
Meet attendees where they already are. A WhatsApp (or SMS, or WeChat) concierge for recommendations, schedules and meeting booking — no download, no login, huge reach at international events.
Volunteer check-in in a phone browser. Venue screens reading the live schedule. Kiosks greeting people by their goals. One database behind every surface — change it once, it changes everywhere, instantly.
→ 14 registrants · became a re-engagement list · logged, with consent, automatically
Questions become queries, queries become lists, lists trigger automations. The analytics backlog becomes an afternoon — and because visibility is live, you fix things Tuesday afternoon, not in the week-three post-mortem.
Your biggest sponsors have dev teams and a CRM. Give them an access key instead of a spreadsheet: they build the prospecting view they want, on their budget — seeing only what you've allowed. Meetings they propose arrive as drafts; attendees opt in.

Similar resources, a different ceiling: build more at the speed of sound, iterate even faster — and deliver the best numbers your event has ever had, on surfaces you control, with the proof each stakeholder needs at renewal.
After it: their own dashboard within 48 hours — not an aggregate PDF in week three. Proof an exhibitor can show their CFO renews itself.
Organizers who prove ROI per exhibitor report renewal above 85%, against an industry average of 76% — the difference between defending your pricing and discounting it.
Matching and meeting ops move onto software; 30–50% of staff time comes back — spent on the sponsor and VIP relationships no engine handles. The 80/20 Parry asked for.
Documented results from organizers running connected event data · UFI/Explori · Freeman 2025 · Event Industry News AI Report 2025 · not guarantees — your numbers get measured against your own baseline
Both doors, one contract. And below them, one add-on: if you'd rather have your hosted-buyer program run for you end to end, we do that too.
Run Brella's apps — customized per event brand, maintained by us — and extend them through the API.
The app is part of the show — or a product of your own. You build the surface; Keystone runs the backend.
Mix freely — headless on the flagship, Brella apps on the other thirty-nine. Same database, same contract, same numbers.
Wherever you set it, on us: matchmaking · meetings · data · consent · uptime
It's a dial, not a switch — and you can move it later
A hosted-buyer program end to end: buyers recruited and committed, hundreds of meetings planned and run on-site, outcomes reconciled and reported — results guaranteed in the contract. Service and systems working in tandem. One partner, one invoice.
A sandbox that works in minutes, docs that answer before you ask, engineers who reply like it's their launch too.
Solutions engineers embedded in your project — dashboard, warehouse sync, connectors — built with your team so they own it after.
Custom app, dashboards, integrations — to your spec, maintained by us. Bespoke tech without hiring for it.
Where we price on success — held meetings, rebooking, attributed pipeline — we're invested in your event's outcome the most literal way a vendor can be: it's in the contract.
Budgets are rationed, and sponsors aren't sentimental: if your event doesn't deliver, they'll fund one that does.
Big event or small, Keystone lets you compete with the juggernauts of the events world — at a fraction of the cost and resources, with 99% of the impact.
So are most of the teams doing this well. 55% of the organizers adopting this kind of system run teams of one to fifty. That's the point of renting the hard parts: one contract, our people embedded until it runs.
Keep them. Workbench connects Cvent, Stova, Swoogo, HubSpot and Salesforce two-way. The fix is connection, not another migration.
Ten years running networking at events like yours, millions of meetings booked. And the all-in-one suites can't sell you their backend without cannibalizing their apps — we already accepted where the surface is going, which is exactly why we can sell you the system.
Most event "APIs" are export pipes — pull registrants out, push leads in. Keystone hands you the engines themselves: propose and orchestrate meetings, query matchmaking with the reasoning attached, subscribe to live behavior — through access keys scoped down to the field, with consent and audit enforced on our side of the line. Same for MCP 2.0: not a chatbot bolted onto a database, but the full backend, governed, that agents can safely act on. It's the difference between reading about your event and operating it.
No. The engines were built on ten years of Brella's own operating history. What your events generate improves your events — nobody else's. It's in the DPA, not just on this page.
No. Your data is exportable from day one — full, structured, yours. Use the whole stack, one API, or anything between, and change your mind later. We intend to be hard to leave because everything works, not because the door is locked.
Live: the event database, the read/write API with per-key field-level scoping, Brella's apps, meetings and matchmaking in production, behavioral tracking, audit logging. Rolling out with design partners: the recommendations API with reasons attached, plain-language querying, the Pulse SDK, and the MCP 2.0 connection for agents. We'll always tell you which side of the line a feature is on.
Platform plus usage — you pay when the engine works, per profile matched and meeting orchestrated. Usually less than one retained developer. And the retention math is blunt: replacing one churned exhibitor costs about five times keeping one.
A portfolio operator, a flagship builder, an agency-run hosted-buyer program. We put one of your events on Keystone, measure meeting acceptance, exhibitor proof-of-ROI and renewal against your current baseline — and shape the platform around what your team builds. Discounted first year, our team embedded in your launch.
