|---|---|---|---|---|---|
| Sep 2026 | Undisclosed stage | Bessemer Venture Partners (lead); TCV (lead); Leaders Fund; Alta Park Capital; Salesforce Ventures; Cyberstarts; Greylock; Craft Ventures | $300M | $3.8B | Upwind raised $300 million in September 2026 at a $3.8 billion valuation in a financing led by Bessemer Venture Partners and TCV, with participation from Salesforce Ventures, Greylock, Cyberstarts, Leaders Fund, Craft Ventures, Alta Park Capital, and other existing backers. The round significantly increased the company’s valuation from its earlier January 2026 Series B and added fresh capital to accelerate growth in AI security and cloud security products. Upwind is a cloud security company founded by Amiram Shachar and positioned around runtime-first security for cloud and AI applications. Its platform is used to secure cloud environments across code-to-runtime visibility, developer-first security, and broader cloud protection use cases, and the company has expanded its investor base across multiple financing rounds. At the earlier January 2026 Series B, Upwind raised $250 million at a $1.5 billion valuation, bringing total funding to $430 million at that time. Investors included Bessemer Venture Partners, Salesforce Ventures, Picture Capital, and existing investors such as Alta Park Capital, Greylock, Cyberstarts, Leaders Fund, Craft Ventures, TCV, Cerca Partners, Swish Ventures, and Penny Jar Capital. |
| Jan 2026 | Series B | Bessemer Venture Partners (lead); Leaders Fund; Alta Park Capital; Salesforce Ventures; Swish Ventures; TCV; Cyberstarts; Picture Capital; Greylock; Penny Jar Capital; Craft Ventures; Cerca Partners | $250M | $1.5B | Upwind Security is a cloud security startup founded in 2022 by the former leadership team of Spot.io, which was acquired by NetApp for around $450 million in 2020. The company provides a runtime cloud security platform using an eBPF-based sensor for real-time visibility into workloads, configurations, and applications, focusing on monitoring internal signals like API traffic and network requests to detect risks and reduce alert noise in cloud-native environments. It positions itself as a comprehensive solution contrasting traditional outside-in scanning methods, with expansions into AI security and developer tools to prevent misconfigurations. Upwind raised $250 million in a Series B funding round in January 2026, led by Bessemer Venture Partners, with participation from Salesforce Ventures, Picture Capital, and existing investors including Greylock, Cyberstarts, Leaders Fund, Craft Ventures, TCV, Alta Park Capital, Cerca Partners, Swish Ventures, and Penny Jar Capital. This round brings total funding to $430 million and values the company at $1.5 billion post-money, making it the first unicorn in modern cloud security according to CEO Amiram Shachar. The funding follows a $100 million Series A in late 2024 at an estimated $800-900 million valuation and aims to accelerate scaling, product development, go-to-market efforts, and channel partnerships, having added over 100 partners including MSPs and VARs in the past year. The company reports 900% year-over-year revenue growth and has doubled its customer base, serving global enterprises such as Siemens, Peloton, Roku, Wix, Nextdoor, and Nubank. Most major accounts came through channel partnerships. Upwind has received recognitions like CRN's 2025 Stellar Startups list and was reportedly in acquisition talks with Datadog for around $1 billion in 2025. The runtime-first approach addresses the evolution of cloud infrastructures, particularly in the AI era, by prioritizing real threats in integrated platforms amid an overcrowded security market. |
| Dec 2024 | Series A | Craft Ventures (lead); Leaders Fund; Alta Park Capital; TCV; Sheva Capital; Cyberstarts; Greylock; Penny Jar Capital; Cerca Partners | $100M | $900M | Upwind Security is an Israeli-founded cloud security startup offering a runtime-first platform with real-time visibility into workloads, configurations, and applications using eBPF-based sensors, protecting cloud infrastructure amid AI and data growth. Founded in 2022 by former Spot.io leaders (acquired by NetApp), it serves enterprises like Siemens, Peloton, Roku, Booking.com, and Nubank, emphasizing integrated CNAPP solutions to address overcrowded security tools. In December 2024, Upwind raised $100 million in a funding round at a $900 million company valuation, aligning with investors such as Alta Park Capital, Cerca Partners, Craft Ventures (lead), Cyberstarts, Greylock, Leaders Fund, Penny Jar Capital, Sheva Capital, and TCV. This Series A (per some sources) brought total funding under $200M at the time, aimed at expanding operations across Israel, US, and UK offices, meeting cloud app protection demand, doubling workforce to around 300 employees (150 in Israel), and scaling product engineering. The round preceded a larger January 2026 Series B of $250 million led by Bessemer Venture Partners at $1.5 billion valuation, reaching unicorn status and total funding of $430 million, with participation from prior investors plus Picture Capital and others. Funds supported AI-enhanced detection, real-time risk insights, go-to-market expansion, and unified platform development for security, DevOps, and engineering alignment. Upwind reported 900% revenue growth and 200% customer base increase over the past year leading to the 2026 round, plus over 100 new channel partners including MSPs and VARs, with most big accounts from channels. It positions as the first unicorn in modern cloud security, capitalizing on digital transformation, cloud migration, and AI-driven threats like ransomware. Competitive context highlights challenges in adopting new runtime approaches over traditional agents, but strong validation from market recognition (e.g., CRN Stellar Startups 2025) and customer adoption underscores its traction in the booming cloud security space. |
