Built on the Big Five — the dominant model in personality research, not pop psychology.
OCEAN captures how you think, work, and relate — not how much uncertainty you will underwrite before there is proof. GFTI adds Venture Drive as a sixth axis: founder appetite for betting on the unproven. Two co-founders can match on all five traits and still deadlock on whether to pivot, raise, or kill the bet. That gap is worth naming before you split equity.
Continuous traits plus a memorable inner ghost — nuance and a label that sticks.
Like MBTI, each pair comes with a plain-language “how.” OCEAN covers five founder traits; Venture Drive is the sixth.

How you bet when the payoff is still unknown.
Venturous founders ship into ambiguity; prudent founders wait for proof.
Venture DriveVenture Drive is what makes this a founder test. Two people can match on all five OCEAN traits and still disagree on whether to bet the company on an unproven idea.

Your inner ghost is your orientation — how you bet and build. A co-founder with a different ghost is often the point, if you know where you differ before the equity talk.
Speed meets patience — one ships into fog, one builds the system that survives it.
Reliable execution meets bold signal — one keeps the engine running, one forces the hard conversation.
Stealth exploration meets pressure execution — one finds the angle, one closes when it's time.
Opposite Venture Drive — Venturous vs Prudent — is the pairing worth discussing early.
Open to new and returning founders — start whenever you are ready.
