Upwind is a next-generation cloud security platform founded in 2022 by the team behind Spot.io (sold to NetApp for $450M), offering runtime-first CNAPP capabilities that combine cloud security posture management with real-time threat detection and response. The platform reduces security alert noise by up to 90%, enabling enterprises to focus on genuinely critical risks across cloud workloads, containers, APIs, and identities. In January 2026, Upwind closed a $250M Series B led by Bessemer Venture Partners at a $1.5B unicorn valuation, bringing total funding to over $430M. The company has seen 900% year-over-year revenue growth and counts Siemens, Roku, Peloton, Wix, and Nubank among its enterprise customers, with a growing presence in Belfast, Tel Aviv, San Francisco, and Iceland.
