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 work you're already doing becomes a record that opens doors.
Active Guild Member Since2026A living record of what you build, verified as you go.
Activate your membershipMost systems begin with pedigree: where you went to school, where you worked, who introduced you and where you happen to live. f3 begins with proof: what you are building, what you have shipped, whether you follow through and who is willing to stand behind you.

Active Guild Member Since2026The 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.
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.
The work you've already done becomes a living record, and that record starts opening doors immediately.

Founders, co-founders and operating teams turning an idea into something real — and making that work visible as it happens.
People and institutions prepared to fund builders — and willing to source on verified proof instead of warm introductions alone.
Believers are the widest part of the guild: the people and institutions creating opportunity, lending experience and looking for the right work to join.
Institutions that create the conditions for builders to begin.
People who bring judgment, reputation, access and practical help.
People looking for the right builder, idea or team to join next.
Founders, co-founders and operating teams turning an idea into something real — and making that work visible as it happens.
The things founders ask us in the first five minutes. If yours isn't here, talk to f3.
f3 is a free membership for people who build things. We become your first true believer; then it's on you to log the proof. Founders are the talent, and f3 is the first talent agency built to represent them.
Yes. Your Proof Score, Proof Page, and Accountability Agent are free for as long as you're building. Upgrades are premium services you choose when you want them, like a Consigliere in your corner. Nothing is gated behind a paywall that you need on day one.
Any builder, anywhere, at any stage. Backers (angels, funds, and the people who work in them) and Believers (mentors, interns, cofounders) join by invite, or request one from the activation page.
A live number out of 1,000 across four pillars: EDGE (your durable advantage), PULSE (execution), TRUST (who's in your corner), and SIGNAL (is your message landing). It's built from verified activity, not pitch decks or who you know, and it moves as you build.
Most members arrive with one. If you don't have an invite, request one from the activation page and a person at f3 reviews it, usually within 24–48 hours.
That's exactly who f3 is for. At the earliest stage the data everyone else scores doesn't exist, so we create it: proof of how you build, made every day. Your first proof can be a kept promise, a customer call, or a shipped feature.
It knows what you said you'd do this week, and checks. You can connect the tools where proof already happens (GitHub, your calendar, your CRM) so it verifies rather than asks. Kept promises become verified record.
Your Proof Page is yours. The public tier shows your headline score, pillar shape, and archetype. The proof log, momentum, and financials stay private unless you share them. The same rules apply to agents reading the machine view.
No. Membership gives you native standing in the startup ecosystems closest to you and the ones you want to be part of. Relocate on your terms, or stay home. Either way, you're already in the room.
Every f3 asset ships with a machine view one flip away: the same proof, formatted for the AI agents that now scout talent, source deals, and check references. It's how you get found by the systems people increasingly use to decide.
