Cloud security startup Upwind secured $400 million in Series C funding at a $3.8 billion valuation. The firm rejected a takeover bid from Datadog, opting to remain independent as it scales its AI-driven security tools. With projections to hit $90 million in annual recurring revenue by year-end, the company's valuation reflects strong investor confidence in the cloud-native security sector.
Upwind, a startup specializing in cloud infrastructure security, has closed a $400 million Series C funding round, pushing its valuation to $3.8 billion. This is a sharp increase from the $1.5 billion valuation the company held just nine months ago. Bessemer Venture Partners led the investment, with backing from existing investors like Greylock Partners and Craft Ventures.
The capital raise follows intense acquisition interest, including a takeover bid from cloud-observability provider Datadog. The company ultimately decided to reject the offer, choosing to remain independent. Management signaled that the bid did not provide a sufficient premium over the valuation set by venture capital investors, reflecting confidence in the company's long-term potential as an independent firm.
Under founder Amiram Shachar—who previously led the exit of Spot.io to NetApp—Upwind has demonstrated rapid scaling. The company is adding between $20 million and $30 million in annualized recurring revenue (ARR) every quarter, with current projections expecting it to reach $90 million by the end of the year. At a $3.8 billion valuation, the company is valued at roughly 40 times its projected ARR. While this multiple highlights the high premium investors are willing to pay for AI-integrated security tools, it also sets high expectations for the company to maintain its rapid revenue growth.
The firm’s technology focuses on runtime security, which identifies and fixes vulnerabilities in active cloud services in real-time. As global organizations prioritize cybersecurity spending to protect against increasingly sophisticated threats, demand for such automated tools has surged. For investors, this sector shift is a key trend, as it impacts the broader software-as-a-service market and the requirements of enterprise clients globally.
While the company has secured significant capital, high valuation multiples bring execution pressure. The company must consistently meet its growth targets to justify its market position. Investors and industry analysts will likely monitor whether the company can sustain its revenue momentum and successfully navigate the competitive cloud security landscape. Given the current market environment, where initial public offerings in cybersecurity are challenging, the eventual success of this strategy will depend on the firm’s ability to scale operations efficiently and potentially position itself for a strategic exit down the road.
