Event Management Software Development

Ticketing, registration, check-in and hybrid event platforms for organisers, venues and conference teams, built for the one day a year when everything has to work at once.

/// INTRODUCTION

Sodio builds event software: ticketing and registration platforms, check-in and badging apps, hybrid and virtual event platforms, conference and venue management, and event apps, plus AI for attendee matchmaking, bot detection and session recommendations. Event software is judged on two days a year.

The day tickets go on sale, when checkout has to survive more traffic in ten minutes than the rest of the year combined. And the day of the event, when check-in has to work even after the venue wi-fi has failed.

/// WHAT MAKES EVENT SOFTWARE DIFFERENT

Judged on Two Days a Year

Events Workstation Setup
01/

The Established Platforms

Eventbrite, Cvent and the established platforms handle standard ticketing and registration well, and for most events they are the right answer. We will say so during discovery rather than quote for a build nobody needs. Custom work earns its place where the event model does not fit, or where an organiser wants to own the attendee relationship rather than rent it.

02/

Release Day

The first day that matters is release day. More traffic arrives in ten minutes than across the rest of the year, and most ticketing failures are not servers running out of capacity — they are inventory race conditions, where the same seat sells twice because two checkouts reached it at once. Queueing, inventory locking and load testing against realistic release traffic are designed in, not added after the first sell-out goes wrong.

03/

Event Day

The second is event day. Venue wi-fi is the least reliable thing at most events, and a check-in system that depends on it creates exactly the queue it was bought to prevent. Scanning apps have to validate tickets offline, and still stop the same ticket being used at two different doors.

04/

The Date Does Not Move

And the date does not move. Everything is planned backwards from it, and load testing happens well before tickets go on sale rather than the week before.

///AI FOR EVENTS

AI for Events

Most people attend events to meet someone they have not met yet. The AI worth building here helps that happen, protects the release from bots, and keeps the venue moving on the day.

Connecting attendees who should meet, by stated interests and behaviour, when none of them have met before.

Learn More

Stopping scalping bots and fake tickets before release day, not investigating them afterwards.

Learn More

Demand-based pricing with caps and clear rules, rather than leaving the margin to resale markets.

Learn More

Personalised agendas across multi-track conferences, so attendees find the sessions worth their time.

Learn More

Entry queues and room overcrowding predicted from registration and scan data before they happen.

Learn More

Attendee questions answered from the event's own agenda, venue and policy information.

Learn More

Session summaries, highlights and follow-up content produced from recordings, reviewed before publishing.

/// HOW WE WORK

How We Work on Event Projects

STEP 1

Event and date discovery

We start from the event date and the ticket release date, and work backwards. Then we map ticket rules, attendee types and what happens on the day at the door.

STEP 2

Free solution architecture

Inventory model, release-day load strategy, offline check-in, integrations and a costed plan dated backwards from the event. Yours to keep — including if the recommendation is to use an existing platform.

STEP 3

MVP in 30 days

The path that matters first — usually ticketing and checkout — working end to end and load tested against realistic release traffic.

STEP 4

Production build in 90 days

Full build with check-in, badging and attendee features, plus a rehearsal on real devices at the venue before the doors open.

/// FAQ

Frequently Asked Questions

Usually you should not, and we will say so. The established platforms handle standard ticketing and registration well. Custom work earns its place when the event model does not fit — unusual ticket rules, recurring event series with their own data, venues running hundreds of events a year, or organisers who want to own the attendee relationship rather than rent it from a platform. That last reason is the most common.

It has to, and that is designed for rather than hoped for. Ticket releases produce more traffic in ten minutes than the rest of the year combined. Queueing, inventory locking so the same seat cannot sell twice, and load testing against realistic release traffic are built in before launch. Most ticketing failures are an inventory race condition rather than a server running out of capacity.

Check-in keeps working. Scanning apps hold the attendee list on the device, validate tickets offline, and sync when connectivity returns — without allowing the same ticket through two different doors. Venue wi-fi is the least reliable thing at most events, and a check-in system that depends on it creates the queue it was bought to prevent.

This is the hard part of event networking and we have built for it directly. There is no history between attendees, so matching relies on stated interests, role, goals and behaviour during the event. We built interest-based matchmaking for Horizon, a community platform whose entire premise was connecting people outside their existing network — the same cold-start problem an event faces.

You can make it expensive enough that most stop. Bot detection at the queue, purchase limits tied to verified identity, named tickets and controlled transfer rules together reduce scalping substantially. No system eliminates it entirely, and anyone promising that is overselling.

For a defined scope we target a working MVP in 30 days and a core production build in 90. Events have one constraint almost nothing else shares: the event date does not move. We plan backwards from it, and we schedule load testing well before tickets go on sale rather than the week before.
