Menlo Ventures' Matt Murphy, a seasoned investor with 25 years of experience, has observed exceptional growth in AI startups, particularly in companies like Anthropic. According to Murphy, Anthropic's rapid expansion to a $47 billion revenue run rate by May is unprecedented in his career, surpassing growth seen in previous tech waves such as the internet, mobile, and cloud computing. Murphy's comments come after Menlo Ventures led Anthropic's $500 million Series D funding round.
