Growth over acquisition

Cloud security startup Upwind turned down an acquisition offer from Datadog. Instead, it raised a $400 million Series C at a $3.8 billion valuation.

Same price, different choice

Notably, the acquisition offer matched the same valuation. Upwind's leadership chose to stay independent and grow with fresh capital rather than sell the company.

Why it matters

Cloud security is one of the areas enterprises spend most on as AI infrastructure spreads. Upwind's decision shows security startups can reach large valuations without being absorbed by a bigger player.

What's unclear

The source does not name the investors in the round or Upwind's customer numbers. It also does not say which product or market expansion the funding will target.
