uneven stock splits between founders (a strong indicator of future founder breakups)

I've heard lots of stories about this issue, but I think you're the first person to actually have a statistically significant amount of data to back up what you're saying.

Can you elaborate on this point a bit? In particular, I'm wondering if it's the uneven stock split which is the problem, or if that and founder breakups are merely both symptoms of an underlying issue -- say, different levels of commitment from the founders, or unequal status levels.

Or put another way: If a team applies to YC and says that they plan on a 67/33 equity split, would you convincing them to change to a 50/50 split improve their chances of success, or are they still at a disadvantage compared to teams which originally planned on a 50/50 split?

The reasons I hear often for uneven stock splits are because one founder came up with the idea, or has been working on it for a month longer etc etc. When a company is in its absolute infancy, this seems like a logical conclusion but what about when the company is 5 years old? What we see is that even after only 3 months of YC when the founders are all working as hard as each other under stress and often the idea bears no resemblance to the original idea, that this starts to become a problem. The founder with less stock starts to feel like this is not such a good deal for him / her and it can lead to problems.

There are other reasons for uneven stock and as you mention, different levels of commitment or unequal status levels cause problems too. This is something that we would seek to understand more during the applications process when we see it and to try to make sure the founders have really thought through whether this is what they want. The key to a lot of this is open communication between the founders.

Of course, there are some situations where an uneven split does work. An example would be a founder has a mortgage and a family to support and therefore takes more salary in exchange for less stock.

We do not insist on an even split in any situation but I do always make sure that the founders think through their decision carefully.

Kirsty - What's your opinion on the recent TC article on this subject? http://techcrunch.com/2013/02/09/the-perfect-cap-table/

There's one other source for this data - Noam Wasserman at HBS did an extensive study of startups. His data (in The Founder's Dilemmas) shows that companies that make a "quick and easy" decision to split 50/50 received significantly lower first round valuations than teams that spent more time debating the split (although it then made no difference if the long-negotiated split was equal or unequal). He also believes anecdotally (but doesn't have data) that the quick-equal teams are less successful long term.

Great book, incidentally - this is from page 163, I highly recommend the whole thing.
