Who it's for

Small group. Real builders. If you only want free software and will not ship, skip this.

For

  • Indie builders who can ship a thin slice in a week
  • Solo builders or small teams with an idea or WIP
  • Ready for about 2-3 focused hours per day
  • Willing to use the required tools and show up on Demo Day

Not for

  • People who want freebies without shipping
  • Anyone who will not use ShipStreak check-ins
  • Anyone who cannot commit the week

Details

FAQ

  • Yes. Build Sprint #1 is free. Confirmed seats also get the participant toolkit (about €104 of included access: ShipSafe + one month of ShipStreak). What it costs is commitment, daily check-ins, and shipping with the required badges.

  • Day 0 is Sunday, 2 Aug 2026 (setup, required). Build Mon 3 Aug–Sat 8 Aug. Demo Day is Sunday, 9 Aug 2026. All dates Europe/Dublin. Status chips show the build week 3 Aug → 9 Aug 2026.

  • Sprint calendar dates use Europe/Dublin. ShipStreak check-ins are once by the end of your local calendar day (plus the usual ShipStreak grace). You do not need to be awake at Dublin noon for prompts.

  • ShipStreak is required for daily check-ins. Greenfield projects use ShipSafe with the Built with ShipSafe badge. Existing WIP: use ShipSafe with the badge, or keep your stack and add the Built During KLJr Sprint watermark. Details on the rules page.

  • A public URL with a full app flow by Demo Day. A real finished product a stranger can try, not a landing-page mock.

  • Plan for about 2-3 hours. Async-first, with check-ins, one mid-week office hour, and Demo Day.

  • Miss Day 0 (Sun 2 Aug) and the seat is released. Check-ins run on ShipStreak: one grace day if you miss an update there; miss two and you're out. For Build Sprint itself there is no pausing. Seven days is short. Ship every day.

  • You get an automatic confirmation email straight away. I review requests myself. Closer to Day 0 (Sun 2 Aug) I send the onboarding email with Discord access, the Day 0 checklist, and the toolkit.

  • Occasional notes from me on shipping in public, Build Sprint seats when they open, and what I am building. Low volume. Separate from a seat request, though you can join both.

  • Demo Day is for the group. With your consent, demos may be recorded and showcased.

  • Join the KLJr.dev newsletter. I'll email if seats open, and I'll tell you when the next sprint is coming.
