Accel

Accel's early bets on Facebook, Spotify, Slack, and UiPath define its legacy, with Jim Breyer's $12.7 million investment in Facebook at a $100 million valuation becoming one of the most profitable venture checks ever written—returning over $9 billion. The firm operates dual hubs in London and Palo Alto, deploying $14 billion across growth equity and venture funds. This global reach gives Accel a 30% higher win rate in European tech than #2 a16z, which concentrates on US markets. Accel's data shows that 40% of its portfolio companies achieve unicorn status within five years.
