Anysphere, a San Francisco-based AI startup founded in 2022 by four MIT graduates has reportedly reached a $9B valuation after securing $900M in new funding. According to The Financial Times report, Thrive Capital led the investment round, which is among the largest ever for an enterprise software startup. The round also includes participation from leading firms Andreessen Horowitz (a16z) and Accel. These firms previously backed Anysphere's $100M round in December, which valued the company at $2.6B. The latest deal more than triples Anysphere's valuation, bringing total disclosed funding to over $1B.
