@20vc_tok: ClickHouse raised its Series B at a $2 billion valuation with no revenue, no product, no customers and just 15 employees. Aaron Katz | Co-Founder & CEO says the round felt expensive at the time, and immediately put a target on the company’s back. What followed was a year of pressure to turn an open-source database into a real commercial product. Today, ClickHouse is one of the fastest-growing infrastructure companies in the market. #ClickHouse #startups #20VC #fulhamfc
