Upwind Security Raises $250M – But Why?

On January 26, 2026, Israeli cloud security startup Upwind announced it just closed a $250 million Series B led by Bessemer Venture Partners. The valuation? $1.5 billion. That makes Upwind officially a unicorn. But here’s the real story-this isn’t just another funding announcement. This is about a company that went from $300 million valuation (September 2023) to $1.5 billion in roughly two years. That’s a 5X jump. Let’s break down what’s actually happening.

Why It Raised $250M – Main Reason

Here are the core reasons Upwind captured $250 million:

• 900% Revenue Growth Year-Over-Year: Since December 2024’s $100M Series A, Upwind exploded with 900% ARR growth and 200% customer growth. When a cybersecurity company is growing like that, VCs throw capital at them. This isn’t slow-and-steady growth-this is “grab market share before competitors catch up” growth.

• Cloud Security Market is Massive and Still Maturing: The global Cloud-Native Application Protection Platform (CNAPP) market is projected to hit $18.79 billion by 2029, growing at 28% per year. Gartner predicts 40% of enterprises will rely on CNAPP solutions by 2029. Upwind is positioned to own a meaningful slice.

• AI Acceleration Changed the Game: Cloud infrastructure evolved faster than security models protecting it. As enterprises accelerate AI adoption, cloud attacks become more sophisticated. Upwind’s “runtime-first” approach solves a problem that’s becoming critical right now.

• Proven Founder with Track Record: CEO Amiram Shachar founded Spot.io, which NetApp acquired for $450 million in 2020. Investors know he can scale companies and exit big. The founding team (Liran Polak, Tal Zuri, Lavi Ferdman) came from Spot.io too. This isn’t first-time entrepreneurs-this is a team that’s already won.

• Enterprise Traction is Real: Fortune 500 companies are signing up. Named customers include Siemens, Peloton, Roku, Nubank, Wix, BILL, ClickUp, Carvana, Fiverr, Agoda, and Waste Management. These are real, household names, not startups. That validates the product-market fit.

Where Will Upwind Use the Fund ?

Upwind announced the $250 million will go to four key areas:

• Aggressive Global Expansion: From 150 employees (a year ago) to 300+ employees now. They’re hiring aggressively across San Francisco, Tel Aviv, London, and Iceland. More sales teams. More engineers. More customer success. Scaling operations to handle 200% customer growth.

• Product Development Across Three Fronts: The company is expanding its platform across data, AI, and code. They’re advancing AI security capabilities within the core cloud security platform AND extending the runtime-first approach “closer to developers” to prevent misconfigurations before they reach production. This is platform consolidation-doing more with one tool.

• Strategic Partnerships and Ecosystem: Upwind added 100+ new partners (ISVs, MSPs, resellers) in the past year. They launched a partnership with NVIDIA and deepened relationships with AWS and Azure. That network gets even tighter with this capital—more integration, more distribution channels, more ways to reach enterprises.

• International Market Penetration: Building momentum in Australia, India, Singapore, and Japan. Right now, they’re strong in U.S., U.K., and Israel. This money scales those regions and opens new markets where cloud adoption is exploding.

The strategy is crystal clear: dominate the CNAPP category while it’s still consolidating. The cloud security market is fragmented. Companies are using 5-10 different tools (CSPM, CWPP, CDR, container security, identity security, vulnerability management, API security). Upwind offers all that in ONE platform. Consolidation = stickiness = higher customer lifetime value. This capital accelerates that consolidation play.
