Hi HN, I made this challenge with the goal of encouraging indie founders to focus on growth for a few months.<p>The challenge is simple, get 100 new paying customers in 100 days.<p>If you sign up, your project will be added to the leaderboard on the homepage (now filterable by category!).<p>Starting on Monday we'll be collecting weekly updates, verified by screenshots, to confirm how many new users you've added.<p>If you take the challenge and succeed you'll have passed the proof-of-concept faze and graduated to the I'm-building-a-business faze of your startup journey. Good luck!
