The colleagues YC gives founders may matter even more than the partners' advice.

History shows great work clusters around particular places and institutions, and however good you are, good colleagues make you better.

Learning a little from each of many different founders and investors is a better strategy than learning deeply from one mentor.

It worked for him with investors and has worked the same way with founders

Young people should create their own luck by meeting as many peers as possible rather than seeking a single mentor, since different people are experts in different things

One person is an expert at growth, another at fundraising, another at life — you get different things from different people

The summer founders learned more from each other than from their investors, because they face the same problems.

A lot of the problems they face are the same, from dealing with investors to hacking Javascript, and watching each other's presentations may have shown them their mistakes.

The primary value of Y Combinator is the peer cohort rather than the partners or speakers, and every founder benefits from such a cohort whether or not they do an accelerator

Being alongside 100-plus founders going through the same stage is the number one advantage, and it persists after graduation

The biggest benefit of the Thiel Fellowship is the peer group — 19 other young people facing the same entrepreneurial problems that college friends cannot help with

His Stanford dormmates couldn't advise him on things like convincing a 60-year-old ML engineer to join his company because they were dealing with college problems instead

The best mentorship relationships are peer mentorships, where both people become mentors to each other over time rather than remaining in a one-way mentor/mentee dynamic

In his experience relationships evolve that way and both parties end up learning enormous amounts from each other, as with his 25-year relationship with Jerry Colonna

YC should heavily curate peer groups for founders rather than leave networking to them, because founders won't self-organise

An experiment matching groups of six to eight founders for dinner showed it was astonishingly hard to get eight founders to organise anything themselves, yet meeting peer groups was the most valuable thing he experienced as a founder in London

Anyone given prolonged exposure to and mentorship from exceptionally capable people would have to actively try in order to fail

His own outlook was transformed by working with people like John Carmack, senior government officials, and USC research scientists — access most people his age never get; he sees himself as having started as an unremarkable internet gamer

Startup founders are remarkably generous in helping one another, and YC was consciously designed to magnify this, producing something far more intense than a university.

The generosity was noticed in the first batch; founders end up surrounded by partners, alumni and batchmates who want to help and can.
