Upwind raises $400M after walking away from Datadog acquisition offer

If you're building cloud security software, expect more acquisition offers from larger players in the observability and security markets.

Upwind, a San Francisco-based startup specializing in AI-driven cloud infrastructure security, has successfully closed a $400 million Series C funding round, valuing the company at $3.8 billion. This significant investment was led by Bessemer Venture Partners and included participation from existing investors such as Greylock Partners and Craft Ventures. The funding round nearly collapsed due to an acquisition attempt by Datadog, a prominent observability software provider. Datadog's offer, however, did not exceed the valuation set by the venture capital investors, prompting Upwind to remain independent. The startup has experienced rapid growth, adding $20 million to $30 million in annualized recurring revenue (ARR) each quarter and is on track to reach approximately $90 million in ARR by the end of the year. Upwind, founded by Amiram Shachar, employs a "runtime" security approach to detect and address active threats and vulnerabilities in real-time.

Upwind's substantial funding and rejection of a Datadog acquisition signal strong investor confidence in AI-powered cybersecurity as a major growth sector, potentially influencing future market valuations and investment strategies. The company's rapid ARR growth, projected to reach $90 million, underscores the increasing demand for real-time threat detection and remediation solutions in cloud environments. This development positions Upwind as a significant independent player, capable of challenging established vendors and shaping the competitive landscape.

The decision to reject Datadog's offer, which reportedly did not exceed the venture-backed valuation, suggests that startups are increasingly prioritizing independence and long-term growth potential over immediate acquisition. This trend may encourage other high-growth cybersecurity companies to hold out for more favorable terms or pursue public offerings, thereby increasing competition and potentially altering consolidation patterns within the security software industry.
