If potential startup succes is judged substantially by the quality of teams, and this is very much dependent on the quality of a team's interaction, empathy and collective intelligence, then having automated recommendations on potential cofounders would be valuable. Even YouNoodle could use its startup data to recommend people on the site it predicts would lead to a quality team and hence a probable quality startup.

If you're going to go with that analogy, what people seem to say is that startups are like a marriage. So a 'matchmaking' service might work out ok, but you won't really know it for a few years.

There's still a problem that no one's figured out matchmaking properly yet. At least not online.

Offline the two main methods are:

- friend set-ups/ Family

- Dating (I think this is what this site does)

Not necessarily. If YC can get its founders to develop a good proto in 10 weeks, why not set an equivalent time frame with your co-founder?

Because human relationships are more complex than code?

Edit: I guess if you just want to do a project to see how things work out with someone, that could be a smart way of getting started; I just wouldn't place much pressure or importance on the project.

Yeah, pretty much.
