Jason Fried reports the results of an experiment where a free event charged a refundable $100 admission, returned at the door to attendees who showed up. Of 55 paid signups, 50 attended, a 90% show rate, compared with 45% for a prior free event that drew more signups. The no-show money ($500) will be donated. Fried acknowledges the sample is small but argues the signal is strong enough to repeat the approach. For product and event builders, it is a concrete example of how a small commitment cost can convert signups into real attendance, with the caveat that the evidence is limited to one comparison.

01Key takeaways

  • A small refundable commitment can sharply raise the show rate of signups.
  • Fewer signups with higher attendance can beat a larger, leaky free list.
  • Measure show rate, not just registration volume, when judging event success.
  • Redirecting no-show deposits to charity can make a commitment mechanic feel fair.
  • Treat small-sample results as a signal worth testing again before generalizing.

02Key sections

The experiment
A free event was reframed with a $100 refundable deposit, returned in person to anyone who showed up. The setup turned attendance into a financial commitment.
Results compared
The paid version had fewer signups but far more attendees and double the show rate of the earlier free event. Attendance per signup rose sharply.
Money to charity
Unclaimed deposits from no-shows will be donated, making the experiment's leftover value go to a cause.
Caveats and next steps
Fried admits the sample is small but sees enough signal to run the format again at the next event.
The experience itself
Beyond the numbers, handing out $100 bills at the door created smiles and a shared memorable start to the day.

03From the post

“Yesterday I wrote about a free event we were throwing which cost $100 to attend, but the full $100 was refunded at the door if you showed up. I said I'd share the results. Ok, so the event was this morning. It went incredibly well. Here are those results: 55 people paid $100 to attend. 50 of those people showed…”

“So this latest event had fewer absolute signups (55 vs. 84), but more people actually attended (50 vs. 38).”Jason Fried · HEY World
