how to run your
demo day.
thirty days of proof.
three minutes each.
no pitch decks.
what demo day is
Demo day is day 30 of your sprint. It's not a pitch competition — it's a proof session. The founders who logged every day show what they actually built. The log history is the evidence. The three minutes is just the presentation layer.
The top 20% of your cohort by consistency earn a demo slot. The rest attend as audience. Both groups matter — the audience becomes the next cohort.
the format (keep this)
Host it wherever you meet — Zoom, Google Meet, your Skool community, anywhere. Set a date before the sprint starts so founders know from day 1 what they're building toward.
Each presenter gets three minutes. Suggested structure:
-
1
share your public dayNumber_ profile
show your consistency grid. day #. log count.
let the proof speak first.
-
2
one sentence on what you built in 30 days
not what you planned. what actually happened.
-
3
show the product
screen share, demo, prototype — whatever you have.
even if it's rough. especially if it's rough.
-
4
one question from the host
the host asks one question based on their logs.
no prep needed. the logs already told the story.
That's it. Three minutes. Move to the next founder.
what happens after
That's up to you.
Some community operators give the top founder an introduction to an investor. Some offer a grant. Some just keep the cohort going into the next 30 days. There's no required outcome — the demo day itself is the milestone.
If you want to add a vote or a prize, you can. dayNumber_ doesn't prescribe what winning looks like. It just shows you who showed up.
tips for hosts
- Keep time strictly. Three minutes is short on purpose — it rewards preparation and clarity.
- Ask about a real log entry, not a polished answer. "On day 17 you logged that you almost quit — what happened?" is a better question than "what's your go-to-market strategy?"
- Let the grid do the talking. Pull up their public dayNumber_ profile during their slot. The consistency grid tells the audience more than any slide ever could.
- Record it if you can. Thirty days of proof, recorded on day 30 — that's a document that compounds.
