The venue held 180. We booked it eleven days before the date because a slot opened and the price halved. We had no sponsors, no advertising budget and a mailing list of just under four hundred people.
The list did most of the work
The first email went out the evening we confirmed the venue. Forty-one tickets in the first six hours, from four hundred addresses. That is a conversion rate no paid channel has ever come close to for us, and it existed only because we had been writing to those people between events.
Scarcity we did not have to invent
With eleven days, the urgency was real and we said so plainly. No countdown graphics, just an honest line about a small room and a short window.
Ten people carried the rest
We asked ten regulars personally, by voice note, to bring one person each. Nine did. Those nine guests bought their own tickets and six of them joined the list.
What did not work
The flyer posts. Good reach, almost no attributable sales. We know because every channel had its own promo code, and the public code redeemed eleven times against the list's ninety-four.
What we would do differently
Sell tables. We priced everything as individual entry and left money on a table we did not offer. Three tables at a premium would have covered the entire venue cost before we sold a single regular ticket.
