About Bloomberg Beta

The fund exists to expand Bloomberg’s horizons by investing in companies built by extraordinary founders that make business work better, with a focus on machine intelligence. Per Crunchbase, Bloomberg Beta has made 352 investments, 48 as lead investor across 214 portfolio companies, with 55 exits including 2 IPOs.
Bloomberg launched Bloomberg Beta in June 2013 with a $75M fund led by Roy Bahat, who had earlier run IGN Entertainment. Karin Klein and James Cham are described as co-founders alongside him. Bloomberg was set up to invest for financial return and to choose companies regardless of any business relationship with Bloomberg. The fund is based in San Francisco, with operations in New York. Wikipedia and Newcomer name three general partners: Bahat, Cham and Klein. Third-party directories also list Angela Martin as a partner. The firm's operating manual is public on GitHub, and it has published an annual Machine Intelligence landscape since 2014. Funds so far: a $75M first fund (2013), a second $75M fund (July 2016), a third $75M fund (October 2019), a fourth $75M fund and a first $75M opportunity fund (June 2022), and a fifth $75M fund (June 2025). Bloomberg is the only limited partner.
Cham is described as the partner with the deepest AI/ML and infrastructure focus, and Klein as active in B2B AI and future-of-work deals. Wikipedia reports that CB Insights ranked the firm the number 2 investor in AI, without giving a date. Third-party summaries say the portfolio leans toward AI/ML, developer tools, workplace productivity, automation and data. The firm says anyone on the team can say yes to a deal independently. On the Lounge deals desk, recent AI rounds include Antares Labs (Seed), Larridin (Seed) and Clay (Series D).
The firm focuses on pre-seed and seed rounds. Some directories also list Series A, and the separate opportunity fund is meant for follow-ons in existing portfolio companies. Bloomberg Beta does not publish check sizes. Aggregator sites estimate $250K to $2M overall, and one lists $25K to $1M for Klein. Treat these as unconfirmed estimates.
