Funding led by Bessemer Venture Partners follows 900% revenue growth and 200% logo growth year-over-year as enterprises adopt runtime-powered cloud security

SAN FRANCISCO–(BUSINESS WIRE)–Upwind, the runtime-first cloud security leader, today announced that it has raised $250 million in Series B funding, bringing its total funding to $430 million. The round was led by Bessemer Venture Partners, with participation from Salesforce Ventures and Picture Capital. Existing investors include Greylock, Cyberstarts, Leaders Fund, Craft Ventures, TCV, Alta Park, Cerca Partners, Swish Ventures and Penny Jar Capital. The Series B marks the beginning of what Upwind calls “The Next Wave,” its next phase of growth focused on scaling runtime-first cloud security to enable a new era of AI and real-time cloud applications for enterprises globally.

Cloud infrastructure has changed faster than the security models designed to protect it, and Upwind is built for next era of cloud security, not where it has been. This funding round reflects growing recognition and validates customers and the market.Share

“Cloud infrastructure has changed faster than the security models designed to protect it,” said Amiram Shachar, CEO & Co-founder at Upwind. “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. This funding round is a small milestone in our journey, but it marks a big day, and it reflects a growing recognition and validates what customers and the market see.”

Cloud security remains a massive and still maturing market, and within that, Cloud-Native Application Protection Platform (CNAPP) has emerged as a core category for securing modern cloud environments. According to Frost & Sullivan, the global CNAPP market is projected to reach $18.79 billion by 2029, growing at about 28% per year. Gartner also predicts that by 2029, 40% of enterprises that successfully implement zero trust in cloud service provider environments will rely on CNAPP solutions for advanced visibility and control. As cloud and AI adoption accelerate, cloud-native architectures have outgrown approaches based on posture snapshots and static signals, which drive heavy alert volume without clearly showing what is truly exploitable.

Upwind was founded on a different belief: cloud security must be built on runtime evidence, the only way to secure the new world of cloud applications, helping teams reduce noise, prioritize real risk and move faster without slowing the business. Today, Upwind is one of the fastest-growing independent cloud security companies in the market, emerging as a challenger to legacy approaches amid rapid industry consolidation.

“Cloud security is already one of the largest and fastest growing segments in cybersecurity, and Upwind stood out to us as the right team with the right product in the right time, building for where the market is going. Their modern, runtime-first approach, focus on signal over noise, and battle-tested founding team have translated into a company and product that are trusted and loved by security, engineering and platform (DevOps) teams, and used as a true platform. We’re very proud to partner with Upwind as they build the runtime-first cloud security platform for the next generation of enterprises,” said Elliott Robinson, Partner at Bessemer Venture Partners.

“Upwind is incredibly impressive. We are honored to invest in and partner with them, as their pace of innovation is relentless. If you have seen them before, I strongly suggest you meet with them again. If you haven’t seen them yet, you owe it to your organization and architecture to see what they’ve built,” said Rakesh Loonkar, Managing Partner at Picture Capital.

Upwind’s momentum reflects more than rapid growth. It signals a broader shift in how enterprises are approaching cloud security as environments become more complex and teams demand stronger context for faster decisions. Since its $100 million funding round just a year ago, Upwind has rapidly expanded its platform and accelerated growth, achieving 900% year-over-year revenue growth and 200% logo growth.

During this period, Upwind scaled its global footprint significantly, expanding its workforce from 150 to more than 300 employees, and deepened its presence across core markets including the U.S., U.K. and Israel – with momentum building in Australia, India, Singapore and Japan. Today, Upwind secures millions of workloads for global enterprises, including Waste Management, Siemens, Carvana, Roku, ClickUp, Wix, Nubank, Agoda, Peloton, Fiverr and BILL, helping security teams cut through noise and focus on what matters most. Customers report a 98% reduction in security alerts and 60% fewer irrelevant CVEs, enabling teams to prioritize real risk using runtime context rather than static signals.

“Cloud security has been missing real context for too long,” said Jerich Beason, CISO at Waste Management. “Upwind changes that by showing us what is actually happening at runtime and why it matters. The agent built on top of the platform lets us interrogate our own data in real time, which saves us time and money while making our cloud security operations more efficient and effective. They are building the future of cloud security, and we are glad we got on board early.”

To support global enterprise-scale adoption, Upwind has also expanded its ecosystem and partnerships. Over the past year, the company added 100+ new partners across ISVs, MSPs and resellers, launched a strategic partnership with NVIDIA and deepened collaborations with hyperscalers, including Microsoft Azure and AWS. Together, these efforts reinforce Upwind’s unified runtime-first approach, positioning the company to continue shaping the future of cloud security as enterprise demand accelerates.

With the new funding, Upwind will move faster across product and go-to-market while continuing to invest in customer support and global growth. The company will expand its platform across three key areas: data, AI and code. This includes continuing to advance its AI security capabilities within its core cloud security platform and extending its runtime-first approach closer to developers to help prevent misconfigurations before they reach production.

Gili Raanan, Founder & General Partner at Cyberstarts, arguably the largest and most successful cyber venture capital of all time said, “Thrilled to partner with Amiram from day 0, and build an important cloud security company in one of the fastest-growing, most innovation-hungry markets we’ve seen – shaped by cloud scale and AI velocity.”

“Upwind’s rapid growth reflects the industry’s urgent need for a new approach to cloud security, one built for real-time challenges. We’ve partnered with Amiram and the Upwind team since the company’s inception and have seen firsthand how they’ve set the standard for category leadership through real innovation and a platform designed for modern cloud environments. We’re incredibly proud to continue partnering with Upwind as they continue to lead the category forward,” said Saam Motamedi, General Partner at Greylock.

“Upwind continues to set the standard for what comes next in cloud security. From the beginning, the team recognized that securing modern, AI-driven cloud environments would require a runtime-centric approach, a view that has since become central to enterprise cloud security strategies. This is our third major investment in Upwind, reflecting our conviction in a customer-obsessed team that is shaping the future of cloud security in the AI era,” said Michael Robinson, Partner & Head of Investment Team at Craft Ventures.

“We’ve believed in Amiram and the Upwind team since the Spot.io days, and our conviction has only grown as the company has executed. Each time we’ve had the opportunity to invest further, we’ve doubled down. The shift away from static security approaches is inevitable in an AI-powered, real-time cloud security world, and Upwind is purpose built for how modern cloud environments actually operate. This is the team setting the standard for cloud security in the largest market in the cybersecurity industry,” said Gideon Hayden, Co-founder & Managing Partner at Leaders Fund.

“We at TCV aspire to invest in markets and companies that can compound over decades. We believe Cloud Security is such a market and Upwind is such a company. This $250M Series B investment suggests we aren’t alone in our belief. Up & Up!” said Morgan Gerlak, Partner at TCV Velocity.

“As cloud security shifts towards runtime at an accelerating pace, we believe Upwind has emerged as the clear leader in this new paradigm with the first and only runtime-native cloud security platform. Upwind’s runtime-centric CNAPP has now been battle-tested by leading enterprises with some of the most complex and demanding cloud environments. Since our initial investment in Upwind over a year ago, it’s been remarkable to witness the team’s exceptional customer-centricity and product velocity as they continue to deliver new capabilities and define the future of cloud security,” said Carson Fullard, Managing Director at Alta Park.

“We have tremendous confidence in Amiram and the team at Upwind. He leads by example, holding himself to the highest of standards to inspire those around him to achieve excellence for customers. We’re proud to support Upwind in their next phase of growth,” said Bryant Barr, Founding Partner, Penny Jar Capital.

Upwind has been recognized by analysts and third parties across the cloud security market. The company was named CNADR Company of the Year by Frost & Sullivan, and recognized as a Leader and Outperformer in Container Security by a leading tech practitioner analyst firm. Upwind was also recognized in the Gartner 2025 Market Guide for CNAPP and included in three Gartner Hype Cycles, and is rated 4.9 out of 5 on Gartner Peer Insights in the CNAPP category. The company was named to Fortune’s Cyber 60, recognized as a CRN 2025 Stellar Startup in Security, and named a Leader and Emerging Innovator in the QKS Group SPARK Matrix™ for CNAPP 2025, with a top-right quadrant placement in ISMG’s 2025 CNAPP Market Guide.
