About
Upwind was founded in 2022 by Amiram Shachar (CEO), Tal Zur (CTO), and Lavi Ferdman, the founding team behind Spot.io, a cloud infrastructure cost-optimization company that was acquired by NetApp. That background in large-scale cloud operations shaped Upwind's approach to security: rather than layering static configuration scanning on top of the cloud, Upwind ingests real-time runtime signals (processes, network flows, identities, and API calls) to detect and stop active threats as they happen.

Overview
Upwind Security is an AI-native cloud security platform built by the team behind Spot.io, a cloud infrastructure optimization company acquired by NetApp. Founded in 2022 and headquartered in San Francisco with a major research and development presence in Tel Aviv, Upwind combines runtime detection and response, cloud security posture management, vulnerability management, and identity security into a single real-time platform.
In September 2026, Upwind became what it describes as the first unicorn valuation in the modern cloud security category, closing a $300 million Series C at a $3.8 billion post-money valuation less than eight months after its $250 million Series B. The company has cited revenue growth of more than 900% year-over-year following its December 2024 Series A, and reported more than 200 enterprise customers as of early 2026.
Private securities are speculative, illiquid, and involve risk of complete loss of principal. You should be prepared to hold private securities for an extended period; there is no assurance of a secondary market, an IPO, or other liquidity event. You are fully responsible for conducting your own due diligence. Pricing is indicative — nothing here is an offer of securities.
