Conclusion. No matter how you calculate it, it is very unlikely that Paul Graham isn't a billionaire, at least on paper. He had founded YC before he met Sam Altman, and Sam Altman's net worth is at least $2 billion, which he earned solely thanks to his connection to YC.

As of late 2023, Y Combinator had invested in over 4,000 companies, most of which are for-profit, holding a combined valuation of $600 billion.

Startups are not for everyone. The hours are long, the route to success is often unconventional, and it is certainly not a surefire way to make a large sum of money. Roughly 90 percent of startups end in failure. (YC is an exception; over 50 percent of YC companies that are over five years old are still alive).
