Overview
Flume Water provides smart home water monitoring and leak detection technology that helps homeowners track water usage, detect leaks in real time, and prevent costly water damage. The company's patented sensor attaches directly to existing water meters without requiring any plumbing modifications, reading the magnetic field to detect usage down to one-hundredth of a gallon.
Founded by three Cal Poly San Luis Obispo students during California's record drought, Flume has grown to serve over 250,000 homes across the United States. The company has built significant partnerships with major insurance carriers, positioning its technology as a loss prevention tool that reduces non-weather water damage claims by up to 70%.
Flume's insurance-focused value proposition addresses the largest loss category for US P&C carriers: non-weather water loss, estimated at approximately $20 billion annually. With 70% of users detecting a leak within 30 days of activation, the platform delivers measurable claims reduction for carrier partners.
