Pay for one event. No subscription.
Your first events are free. After that, set a few levers and you'll see the exact price before you check out. Bigger or recurring needs go to Enterprise.
That's a big room. Events this size are best as an Enterprise plan — recurring events, practice seats, and custom challenges, priced for the relationship.
Talk to salesIndicative pricing — your exact total is confirmed at checkout. Your first events are free; players never pay.
The badge stays on — every tier, always. Your leaderboard shows a small "Powered by PromptInjects · run your own" credit. Private & branded events and Enterprise can add your logo alongside it (co-brand), but it's never white-label. It's how the next host in the room discovers us.
Running events all the time? Let's build the relationship.

Hosting questions, answered
How much does it cost to host an event?
Your first events are free. After that, each event starts at $99 and scales with room size, number of days, and whether it's private & branded. A private, branded ~50-player single-day event lands around $300–500. The calculator shows your exact price before checkout — there's no subscription.
Do players need to install anything or log in?
No. Players scan a QR code and play in the browser — no login, no install, any phone. You spin the event up in about a minute.
Is there a monthly subscription?
No. Regular hosting is pay-per-event, because most people run events every few months. The only subscription is Enterprise, for teams with recurring events, practice-mode seats, and custom challenges.
Can I brand the event with my own logo?
Yes — choose private & branded and add custom co-branding, and your logo appears alongside ours. The "Powered by PromptInjects" badge stays on the leaderboard on every tier; we co-brand but never white-label.
What if I need recurring events or custom challenges?
That's Enterprise: an annual subscription with practice-mode seats, recurring or unlimited events, custom-developed challenges modeled on your own stack, and speaker engagement on request. Talk to sales to scope it.
