This week General Catalyst led a $10M round in Matiks, a brain-games app that grew from 22,000 daily users earlier this year to over 300,000 by September. The line that stuck with me came from General Catalyst partner Rahul Humayun: "We found the Matiks vision, product, and most importantly the community to be truly N of 1." One number explains why. Matiks says users who complete a seven-day streak show 62% retention one month later. That's the lesson for every funded team planning a launch or TGE. Launch day buys you attention, and the first seven days decide who stays. Here's how I'd build that first week: 1. Give people a reason to come back tomorrow. A daily challenge, a quest, a drop, a question of the day. 2. Make progress visible. Streaks, roles and points show people how far they've come. 3. Let members play together. Matiks is built on head-to-head duels. In a community, that means leaderboards, contests and member-vs-member events. 4. Celebrate your regulars in public. The people who show up on day 7 become your loudest voices on day 30. 5. Plan week one before launch day. Map days 1 to 7 as carefully as the announcement itself. We've seen how much this compounds with our clients. One client's community grew from 0 to 1,250 members in 113 days, and Hello Minds hit 1.14M impressions in 48 hours. At Keewy we build and run communities for tech, AI and crypto teams, from launch day through the weeks that decide who stays. If you have a raise, launch or TGE coming up, book a call through
