Would you join a 7-day build sprint?

I'm running a small experiment called Build Sprint.

The idea is simple:

• 10 founders

• 7 days

• Ship one real product

• Demo Day at the end

No courses. No "growth hacks." Just building alongside other founders with daily check-ins and accountability.

One thing I'm still thinking about is what actually makes people finish.

If you've participated in a hackathon, build challenge, or public sprint before:

What kept you motivated until the end?

Was it:

• public accountability?

• community?

• daily goals?

• a fixed deadline?

• something else?

I'd genuinely love to hear what worked (or didn't). If you're curious about the sprint itself, I'm happy to answer questions too.
