Upwind, a San Francisco startup that uses AI to secure cloud infrastructure, has raised a $400 million Series C at a $3.8 billion valuation, TechCrunch reported Wednesday. Bessemer Venture Partners led the round, with Greylock Partners and Craft Ventures among existing backers. The round comes nine months after a $250 million financing at a $1.5 billion valuation.

A person familiar with the company said the round nearly fell apart after Datadog tried to buy Upwind and did not offer a premium above the $3.8 billion venture price, so Upwind declined. Datadog sells software that monitors how applications run.
