About
Built for people who run events as a profession.
EventOS started because conference teams were still gluing together a website, a form, a payment page, a spreadsheet, a scanner, and a separate mobile app. That stack fails at the door.

Customer success and onsite support
We sell to associations that run an annual meeting and a calendar of education days, to agencies that cannot afford a different stack per client, and to corporate teams that need the event to look like the brand.
The product principle is simple: one attendee graph. If registration, check-in, and the app disagree about who is in the room, the platform has already failed.
Personalization and AI sit on that graph — they are not a separate product. Session recommendations only work if you already recorded what people registered for, viewed, and attended.
