velsa
The operating system for event venues.
One system for bookings, contracts, exhibitors, and operations — built for the teams who run real venues.
Bookings & contracts
From inquiry to signed contract in one flow. Spaces, dates, pricing, and signatures — without the spreadsheet.
Operations & staff
Layouts, work orders, exhibitor orders, and shift assignments, coordinated across the team that delivers the event.
Reporting & accounting
Fund accounting, invoicing, and the reports your organization actually needs — not the ones a generic platform thinks you need.
Built differently.
No lock-in — your data exports in full, any time, and the core is open source. You work directly with the people who build and secure Velsa, not a support tier. And it's built with the security engineering of a team from a federal-software background — rigor first, not bolted on.
See it for yourself.
Velsa is live today as a demo with realistic seeded data. Have a look, or reach out if you'd rather talk.
