This month we're hosting a free group challenge for SaaS founders. The goal is simple: get 100 new paying users in 100 days. Source: almost 2 years ago

This last year we went from about 400 members to now over 2,000 (counting by active Slack members). A lot of the growth came from a challenge we ran called 100 users 100 days. The idea of the challenge was to get 100 new paying users in 100 days, with a leaderboard and weekly mastermind sessions for accountability. Definitely hope to run another round of the challenge soon. Source: over 2 years ago

- Try a public challenge like http://100in100.co. You'll get grouped with other entrepreneurs who are learning just like you. - Source: Hacker News / almost 3 years ago

Yes, when I look at https://indiepa.ge/ for example, it lists people with 21 startups, 15 startups, 10 startups... It gave me a wierd feeling. It seems so out of place and unrealistic. If instead it would say: 21 products, 15 products, 10 products... The list would look much more sensible. - Source: Hacker News / 6 months ago

Just a personal website is a good place for that. But there are things like https://indiepa.ge/ or your personal profile on indiehackers.com - even though it may not be so much for "graveyard purpose". Source: 8 months ago
