5/ Y Combinator & Finding a Co-Founder

In 2012, Brian left Airbnb and applied to Y Combinator with his Bitcoin idea.

They accepted him, but told him to find a co-founder.

So he posted on Hacker News — and that’s how he met Fred Ehrsam, a former Wall Street trader who was also into Bitcoin.

They teamed up and got $150K from YC to start Coinbase.
