Stamp
Sponsor codes gated on a real door check-in, plus one vote each at the open mic.

Turns showing up into an account for the night. An attendee proves the email on their Luma ticket through a magic link, Stamp checks the guest list server-side and fails closed, then a row-locked pool assigns one code per sponsor — a second click returns the same code instead of a new one. The same stamp runs the open mic: the organiser builds the ballot live as teams demo, every stamped attendee gets one vote they can move until it closes, and closing it publishes the standings. Built for Cursor Macedonia nights.
