Upwind, a security company based in San Francisco, has raised $400 million in a Series C funding round, lifting its valuation to $3.8 billion, according to Ventureburn and Decrypt.
The round represents a sharp rise from the company's Series B financing in January 2026, which valued Upwind at roughly $1.5 billion. The new figure marks a substantial increase within the same year. Decrypt reported that Upwind says its revenue quadrupled in 2026.
Founded in 2022 by Amiram Shachar, Liran Polak, Lavi Ferdman and Tal Zur, Upwind builds a security platform for cloud environments and artificial intelligence. Shachar previously co-founded Spot.io, which NetApp acquired for $450 million in 2020, after which the founders shifted their focus to cloud security.
