Cybersecurity Startup Upwind Secures $400 Million in Funding
After rejecting an acquisition offer from Datadog, the company has chosen to pursue an independent path.

Maintaining Independence and New Investment
San Francisco-based startup Upwind, which leverages artificial intelligence to secure cloud infrastructure, has successfully closed a new Series C investment round. The company raised $400 million, bringing its market valuation to $3.8 billion. The round was led by Bessemer Venture Partners, with participation from existing backers including Greylock Partners and Craft Ventures.
This financial milestone is particularly notable given that the company was valued at $1.5 billion just nine months ago. Industry reports indicate that the round nearly fell through after Datadog, a provider of monitoring and software management tools, attempted to acquire Upwind. However, because Datadog's offer did not exceed the $3.8 billion benchmark set by venture capitalists, Upwind's leadership declined the deal, opting to continue its independent growth.
Technological Approach and Growth Rate
Founded four years ago, Upwind’s rapid expansion is directly linked to the rising threats within the cybersecurity landscape. The company employs a "runtime" security approach, which automatically detects and neutralizes attacks while services are actively running. This strategy has generated between $20 million and $30 million in quarterly annual recurring revenue (ARR), with the figure expected to reach $90 million by the end of the year.
The company was founded by Amiram Shachar, who previously sold his cloud cost management startup, Spot.io, to NetApp for $450 million. According to experts, cybersecurity represents the third major wave of AI-driven software, following coding tools and customer support systems, in which companies are prepared to make significant investments.
What This Means for the Industry
Although Upwind rejected Datadog's offer, market trends suggest the startup remains an attractive target for various technology giants. Given the limited number of cybersecurity companies going public in recent years, an eventual acquisition remains the most likely scenario.
