Israeli startup rejects $4 billion acquisition offer

Instead, Upwind is closing a $300 million funding round at a valuation of about $3.8 billion. It was previously reported that the company plans to raise $400 million at the same valuation, led by TCV and Bessemer funds.

Let us remember that last year the parties already negotiated a deal worth about a billion dollars, but it did not take place. Upwind then raised $250 million at a $1.5 billion valuation in a round led by US venture capital fund Bessemer.

Upwind develops real-time monitoring systems for applications and AI agents to identify cyber threats. Datadog sells software for monitoring the performance of programs and cloud services in companies. Buying Upwind would allow it to monitor the performance of AI models and agents in real time.
