Frequently Asked Questions

Everything you need to know about the FI 50 and our fastest growing portfolio companies.

The FI 50 is an annual list curated by the Founder Institute recognizing the 50 fastest growing companies from our global portfolio. Each year we highlight alumni who demonstrated exceptional growth through funding milestones, revenue expansion, key partnerships, or landmark achievements.

Companies are evaluated on key growth metrics including funding raised, revenue growth, team expansion, strategic partnerships, and notable press or awards received during the year. Our global team reviews alumni updates across all active regions to compile the final list.

Rising Stars are early-stage startups from our alumni network that are showing exceptional momentum and potential. These companies are recognized for outstanding early traction — even if they have not yet reached the scale of the main FI 50 list.

The FI 50 is selected exclusively from Founder Institute graduates. Alumni who demonstrate significant growth milestones during the year — such as a major funding round, acquisition, or key commercial partnership — are considered. Stay active in our alumni network and keep your profile updated.
