Broadway Angels
Broadway Angels is an invitation-only angel network of senior women in tech and venture capital, founded in 2010 in San Francisco. Broadway Angels backs early-stage technology companies, not water. Its only water bet is KETOS, a water-intelligence platform for utilities, backed across two rounds. As of 2026 that single company earns Broadway Angels a One-Off water rating.

The take
Broadway Angels is the rare name in a water directory whose whole reason for existing has nothing to do with water. Broadway Angels is an invitation-only network of senior women in technology, founded in 2010 by Sonja Hoel Perkins and Jennifer Fonstad to bring together investors who are, or have been, general partners (the people who run venture funds) at top firms or senior operators at the best tech companies. An angel investor here means someone writing early cheques from their own pocket, and this group writes them mostly into information technology and digital health.
Broadway Angels' single water company is KETOS, founded by Meena Sankaran, a real-time water-intelligence platform that pairs sensors with cloud software to put water-quality data, contamination, leaks, usage, in front of utilities, farms, and industry. For a network that lives in software and data, a company turning water into a live data feed was a natural fit rather than a swerve into pipes and pumps, and it happened to be founded by a woman, which is the kind of entrepreneur this group was built to back. Broadway Angels came in at the Series A and stayed in for the next round.
Broadway Angels earns a One-Off rating in my water tracking, the lowest tier, and that label is the honest one. A newcomer investor scanning for a water specialist should read Broadway Angels as a generalist tech angel network that wrote one water cheque it liked, not as a fund assembling a water portfolio. The deep water expertise here belongs to KETOS and its founder, not to a water partner on the masthead.
What Broadway Angels actually brings water founders is the network behind the cheque: decades of operating and investing experience among women who have backed companies like Salesforce and McAfee, and who tend to advise rather than take board seats. Whether more water deals follow KETOS is an open question; for now KETOS is the entire water story, and for a founder it is a useful one, because the introductions can matter as much as the capital.
