Build Sprint by KLJr

Build Sprint by KLJr is a free, 7-day build challenge for indie founders who want to stop planning and start shipping. Instead of endless courses or accountability groups, participants commit to building one product for seven consecutive days, share daily progress, and finish with a live Demo Day. Every accepted founder receives a toolkit including ShipSafe, ShipStreak, prompt packs, templates, community support, and practical guidance designed to remove friction and help them ship. The first cohort is intentionally limited to 10 founders to keep feedback personal and the experience collaborative.

Indie founders, solo developers and makers who are serious about shipping. Cohorts are intentionally small and built for people willing to commit to seven days

Most founders don't fail because they lack ideas - they fail because they never finish. Build Sprint creates a fixed 7-day deadline, daily accountability, a small cohort of committed founders, and a live Demo Day. Instead of planning for months, participants leave the week with something real they can launch and iterate on.
