f3 · The guild for people who build, back and believe.

Before anyone
believes in you,
we do.

f3 is a membership based guild.
The work you're already doing becomes proof — and proof is what gets you coverage, cofounders, customers and capital. Proof beats pedigree.

The moment you join, f3 reads the work you've already done and the relationships you already have — your accelerator, your angel, your city's program — and turns them into a record that travels with you. Then it starts opening doors you didn't have: a backer who sources on proof, a cofounder in another city, a room you wouldn't have been invited to.

Nothing to pay. Relocate on your terms, or stay home. Either way, you're already in the room.
At the earliest stage, the data everyone else scores doesn't exist yet. So we create it — proof of how you build, made every day.
Your membership card

Dated the day you join. Owned by you. Built to travel.

Your live Proof Score and four pillars sit on it, and it's the same card an agent reads when it checks you out.

Why proof

A résumé is a memory.Your score is a live instrument.

Founders move too fast for static credentials. f3 reads the work as it happens, verifies the receipts, and keeps the signal current.

The foundation

The Proof Score™ — always on.

Every venture on f3 has a living Proof Score™ across four pillars. It tells your story from verified activity — not pitch decks, not who you know. The live score moves as you build.
