About FoundersSigma
FoundersSigma is the online destination for founders to build their profile, find cofounders, recruit beta users, hire talent, and connect with other founders.
Every member gets one public profile that shows what they're building and what they're looking for: a co-founder, funding, hires, beta users, advisors, or just a coffee chat. It's invite-only and reviewed by hand, so the directory stays a curated network of real founders rather than an open feed.
