Nine months ago, Upwind was worth $1.5 billion. As of today, it’s worth $3.8 billion.

That’s the number to sit with: $3.8 billion, set by a $400 million Series C that closed on October 28. The Israeli cloud-security company was reportedly out raising only about $300 million a few weeks ago, and demand pushed the round higher (Globes). Bessemer Venture Partners led, with a long bench of returning backers behind it (Investing.com).

The reason the valuation moved that fast is simpler than the cap table. The company says its revenue roughly quadrupled in 2026.

Upwind’s bet: after Google paid $32 billion to swallow the category’s biggest independent name, the way to win cloud security is to watch what’s actually running — not what a scanner guesses might be wrong.

🧠 Why This Matters

Cloud security is in the middle of a land grab, and it got there because the biggest independent player left the board. In March 2025, Google agreed to buy Wiz for $32 billion, its largest acquisition ever (The Hacker News). That deal did two things at once: it proved how much enterprises will pay for cloud security, and it pulled the clear market leader inside a hyperscaler — which makes every rival hyperscaler and every security-conscious customer start shopping for someone neutral.

Upwind is one of the companies catching that spillover. It plays in the CNAPP market — cloud-native application protection, the layer that watches your AWS, Azure, Google Cloud and Oracle footprints for the gaps attackers actually use (Dealroom). The pitch that’s working: instead of scanning your setup and handing you a list of thousands of theoretical vulnerabilities, it watches live environments and flags the risks that are genuinely exposed right now.

That distinction is the whole business. Security teams are drowning in alerts, and a platform that tells them which ten of the ten thousand matter is worth a premium.

📊 Deep Dive

Here’s how fast this has moved, by the numbers:

  • Valuation: $1.5 billion in January 2026 → $3.8 billion in October 2026. Roughly 2.5x in nine months (Investing.com).
  • The rounds: a $250 million Series B in January, then a $400 million Series C in October — back-to-back nine-figure raises inside a single year (Investing.com).
  • Revenue: under $20 million in 2025, estimated at $50–60 million through 2026, with sources projecting roughly $100 million in annual recurring revenue by year-end (Globes).
  • Age: founded in 2022. This is a four-year-old company (Dealroom).
  • Customers: named logos include Siemens, Roku, Carvana, Nubank, Supabase and ClickUp (Investing.com).

The founder is Amiram Shachar, a repeat operator — his previous company, Spot.io, sold to NetApp for about $450 million in 2020 (Dealroom). That track record is part of why the round filled above target.

“Context is key to managing internal and external risks,” said Amiram Shachar, Upwind’s CEO and co-founder (Investing.com).

Behind Bessemer, the round pulled in Canapi Ventures as a new investor plus returning names including Cyberstarts, Greylock, Craft Ventures, Salesforce Ventures and TCV (Investing.com).

⚠️ The Catch

Now the part the valuation glosses over.

A $3.8 billion price tag on something like $50–60 million of trailing revenue is a multiple north of 60x — the kind of number that only makes sense if the growth curve keeps bending the way it did this year. Private valuations are what one lead investor agrees to pay, not a market clearing price, and they can re-rate down as fast as they re-rate up.

The competition is also brutal and extremely well funded. Upwind isn’t fighting scrappy startups; it’s up against Palo Alto Networks, CrowdStrike, and the Wiz team now armed with Google’s balance sheet. “Runtime-first” is a real technical edge, but it’s one the giants can copy or acquire.

“Upwind gave us visibility into what is actually running, not just what a scan found,” said Michael Cannizzo, CISO of HedgeServ (Investing.com).

That’s a strong customer line. It’s also exactly the sort of claim every CNAPP vendor is now racing to make.

🎯 What Happens Next

Watch two things.

First, whether that ~$100 million ARR target actually lands by year-end (Globes). Hitting it turns a 60x-plus multiple into something closer to 38x on a forward basis — still rich, but defensible. Missing it makes this round look like a top-tick.

Second, watch for an acquisition rumor. Every independent cloud-security company at this size is now a target, because the Wiz deal proved a hyperscaler will pay a premium to own the layer. A four-year-old company growing 4x a year with marquee logos is precisely the profile that gets a term sheet from someone much larger.

🧩 Bigger Picture

Zoom out and the Upwind round is a clean read on where money is flowing in 2026. The capital isn’t just chasing the companies building AI — it’s chasing the companies cleaning up the mess AI-era infrastructure creates. More cloud, more services, more machine identities and more automated deployments all mean a bigger, messier attack surface, and security budgets are following.

Google’s $32 billion for Wiz set the ceiling. Upwind’s $3.8 billion is the market pricing in who might fill the gap underneath it. Whether that price holds depends on a single, unglamorous thing: whether the revenue keeps quadrupling.

Two and a half times more valuable in nine months is a great headline. Staying that valuable in nine more is the actual job.
