Cofounder matching is a market for lemons, much like online dating. The best prospects are either never on the open market, or get snapped up very quickly. So it's always a problem of sorting through many low-quality options to find diamonds in the rough (and if you can find one, upgrading a rough diamond to a shiny diamond is still a nontrivial process). Point being, cofounder matching is inherently a frustrating grind.
