Cofounder relationships are among the most important in the entire company.

Because so few people make an actual long term commitment to what they're building, the ones that do have a huge advantage.

The most common post YC failure case for the companies we fund, is they're incredibly focussed during YC on their company... and after they start doing a lot of other things. They advise companies, they go to conferences, whatever.

The most important thing is that there is clear reporting structure and everyone knows what it is.

Founders need to figure out what the message of the company is going to be.

... We probably funded a rate of something like one out of ten solo teams.

Why couldn't it have been done 2 years ago, and why will 2 years in the future be too late?
