Co-founder matching: what it scores and where it breaks
Co-founder matching is a structured way of pairing a person with a venture on three things: the skills the seat needs, the hours the person can genuinely give, and the stage the venture is at. It works because it makes those three explicit early. It fails when a match is scored on skill alone, because partnerships break on available time and mismatched expectations far more often than on capability.
What a match is actually scoring
A useful matching process compares three things and refuses to average them into one number. The first is skills: what the seat requires against what the person has, with the emphasis on complement rather than overlap. The second is availability: the hours the seat needs each week against the hours the person actually has, which is the variable people most often overstate. The third is stage: an idea-stage venture and a revenue-stage venture ask for different temperaments, and a person suited to one is frequently wrong for the other.
Everything else — sector interest, geography, prior title — is a preference rather than a predictor. It is reasonable to filter on it, but it should not outweigh the three above.
Where matching actually breaks
The common failure is not a skills mismatch. It is a time mismatch that both sides agreed to optimistically. Someone with a demanding job commits to twenty-five hours a week, delivers eight, and within two months the partnership is spending its energy on the gap rather than on the venture.
The second failure is unstated expectations about the role. Two people can agree they are co-founding something and hold entirely different pictures of who decides what. Matching that stops at the introduction leaves this to be discovered later, which is the most expensive time to discover it.
What to do with a match once you have one
Treat a match as a hypothesis rather than a decision. The next step is a small piece of real work with a deadline, then a written agreement covering equity, vesting, cliff, roles and departure. A matching process that produces an introduction and stops there has done perhaps a fifth of the job.
Be equally willing to end it early. The cost of walking away after three weeks is three weeks. The cost of walking away after a year, with equity vested and a product half-built, is on a different scale entirely.
How matching works in this ecosystem
The matching here runs on the same three inputs, against 99 ventures with an open CEO seat: the market the venture is in, the skills its seat requires, and the hours you can give it. The same scoring runs on the home page and in the application form, so the ranking you see before applying is the ranking your application is read against.
The portfolio it scores over spans 14 industries and 4 countries, with 53 ventures in Türkiye and 44 in the United States. Because every seat is a CEO seat, the demand skews commercial rather than technical: 98 of the 99 require sales and 63 require product, against 25 requiring engineering. If your strength is operating and selling rather than building, the arithmetic of this particular portfolio is in your favour.
FAQ
What does co-founder matching actually compare?
Three things: the skills the seat requires, the hours the person can genuinely commit each week, and the stage the venture is at. Sector preference and location are filters rather than predictors of whether the partnership will hold.
Why do co-founder matches fail?
Most often on available time rather than on skill. A commitment agreed optimistically and delivered at a third of that rate turns the partnership into a negotiation about the shortfall.
What should happen after a match is made?
A small piece of real work with a deadline, followed by a written agreement covering equity, vesting, cliff, roles and what happens on departure. An introduction on its own is only the beginning of the process.
