A small invite-only co-op (5-12 people max) where every member commits to one async growth experiment per month and shares the post-mortem. Members trade audience access on launch day and review each other's landing pages weekly.
Active indie founders shipping in public, $0-10K MRR. Strong async-writing habit, willing to commit to one experiment + post-mortem per month, and comfortable trading honest landing-page critiques. Not for stealth-mode lurkers.
