HCAP Partners leads new Flume financing round

SAN DIEGO, CA (June 7, 2023) – HCAP Partners, a California-based private equity firm and nationally recognized impact investor, today announced its investment in Flume, Inc., a company that brings connectivity and intelligence to residential water use. Terms of the investment were not disclosed. Impala Ventures co-lead the Series A round in December of 2021.

As the leader in smart home water monitoring, Flume brings unprecedented insights into residential water use to both homeowners and water utilities. Using Flume, homeowners can save water through 24/7 water monitoring for indoor and outdoor water consumption, customizable leak detection, detailed breakdowns and insights into individual water appliances, and suggested water budgets. With a simple installation process requiring no plumbers or pipe cutting, Flume provides the in-depth water use details and control functionality necessary to mitigate issues before they result in high water bills or costly damages.

“Being a California-based private equity and impact investor, we are keenly aware of the rapidly growing issues our society faces with our most precious resource. By providing such granular levels of control of water use, Flume has positioned itself as the ideal tool for homeowners and water utilities to improve water management amid drought conditions”, said Tim Bubnack, HCAP Managing Partner. “We look forward to supporting the Flume team with capital and resources to grow a valuable business while having a positive effect on water conservation.”

"We are delighted to have HCAP partners on board as we continue to revolutionize residential water use,” said Ric Miles, Flume CEO. “This investment represents a significant milestone for Flume and will enable us to scale our business in pursuit of our mission.
