Cloud security company Upwind today announced raising $250 million in a Series B funding round that brings the total raised by the company to $430 million and its valuation to $1.5 billion.
The new investment round was led by Bessemer Venture Partners, with additional support from Salesforce Ventures and Picture Capital.
The startup is also backed by Alta Park, Cerca Partners, Craft Ventures, Cyberstarts, Greylock, Leaders Fund, Penny Jar Capital, Swish Ventures, and TCV.
Upwind offers a runtime-native cloud security platform that provides organizations with increased visibility into networks, APIs, and data flows.
According to Upwind, amid a massive surge in agentic workflows, its solution can reduce noise and prioritize real risk, without impacting business speed.
The new investment allows the startup to accelerate product and go-to-market initiatives, scaling its runtime-first cloud security platform across data, AI and code.
It will continue to advance the core AI security capabilities of the platform, while expanding the runtime-first approach to help developers eliminate misconfigurations before production.
Since its Series A funding round in December 2024, Upwind has doubled its workforce and deepened its presence across the US, UK, and Israel, while expanding to Australia, India, Singapore and Japan.
Headquartered in San Francisco, California, Upwind was founded in 2022 by Amiram Shachar, who previously founded Spot.io, a company acquired by NetApp for $450 million.
“Cloud infrastructure has changed faster than the security models designed to protect it,” said Shachar, who serves as Upwind’s CEO.
“The next era of cloud security requires a fundamentally different approach, centered in realtime signals. That’s actually the only way to protect the cloud in the new era of AI. We built Upwind for where the cloud is going, not where it has been,” Shachar added.
