You are not partnering with the pitch deck.
Ask investors what kills early companies and the founder split is always near the top of the list. Not the market, not the code: two people who discovered under pressure that they had never actually met. A cofounder compatibility test is worth exactly as much as its input, and self-descriptions are the weakest input there is.
What the read shows a founding pair
Two words
The word each of you reduces to under pressure. Not your roles. Who you are when the runway shortens.
The collision
Where your patterns grind: who goes quiet, who grips tighter, who needs the decision now and who needs the night.
The complement
What each of you carries that the other does not, which is the actual case for the partnership.
How founding pairs run it
Both founders take the read. Eight minutes each, separately, each consenting and each owning their own result.
Share the reads with each other. Both or neither; the symmetry is the point.
Have the conversation the reads open, before the equity split, the vesting schedule, and the first real fight.
When the reads disagree with the plan
Sometimes the reads say what neither founder wanted on paper: the patterns collide somewhere structural. That is not a verdict on the company. It is the map of the fight you were going to have anyway, delivered while it is still cheap. Founding pairs who see the collision early write it into how they operate: who owns which calls, what happens at deadlock, when to bring in the third voice. The read does not decide anything. It just makes sure you both met before you married.
Straight answers
Do we both have to share?
What if the reads clash?
Is this only for new pairs?
What does it cost?
Take the read before you take the leap. The free tier covers both founders, no card. Twenty minutes total, and you walk into the equity conversation knowing who is in the room.
