Upwind Rejects $3.8B Datadog Buyout to Raise $400M Series C at Same Valuation

TL;DR

• Cloud security startup Upwind has rejected a $3.8 billion acquisition offer from observability giant Datadog, choosing to remain independent.
• The company instead raised a massive $400M Series C funding round at a $3.8 billion valuation, matching the price of Datadog's proposed buyout.
• The move signals Upwind's IPO ambitions and intensifies competition in the crowded CNAPP market against Wiz, Palo Alto Networks, and Datadog itself.

A $3.8 Billion Bet on Independence

In a decision that has stunned Silicon Valley and Wall Street alike, cloud security startup Upwind has walked away from a $3.8 billion acquisition offer from Datadog.

Sources familiar with the negotiations say talks were advanced in recent weeks, with Datadog looking to make a landmark push into cloud-native application protection. Instead of selling, Upwind's founders and board chose to chart their own course, betting that the company can be worth far more as a standalone public company.

The rejection is a bold statement of confidence in one of the fastest-growing segments in cybersecurity. Upwind, founded in 2022 by former executives from Spot.io, has quickly emerged as a challenger to Wiz and Palo Alto Networks' Prisma Cloud.

Why Upwind Said No to Datadog

At the heart of the decision was control and timing. Datadog, valued at over $40 billion, has been aggressively expanding beyond observability into security, DevSecOps, and AI-driven cloud monitoring. Acquiring Upwind would have instantly given it a best-in-class CNAPP platform.

But for Upwind CEO Amiram Shachar and his team, selling now would have meant capping their upside. People close to the company say the founders believe the cloud security market is still in its early innings, especially with AI workloads creating entirely new attack surfaces.

Staying independent also allows Upwind to continue partnering across the ecosystem — with AWS, Microsoft Azure, Google Cloud, Snowflake, and even Datadog competitors — rather than being locked into a single platform.

Inside the $400M Series C at a $3.8B Valuation

Rather than cashing out, Upwind has secured a colossal $400 million Series C round at a $3.8 billion valuation — the exact same figure Datadog offered to pay outright.

The round was reportedly led by existing top-tier investors with participation from new late-stage and crossover funds positioning for a future IPO. This brings Upwind's total funding to well over $600 million in just three years, making it one of the most well-capitalized cybersecurity startups in the world.

Critically, raising at the acquisition price sends a clear message to the market: Upwind didn't think $3.8 billion was too low — it just didn't want to sell at any price right now. The fresh capital gives it years of runway to scale sales, R&D, and global expansion without needing to raise again before going public.

What This Means for the CNAPP Wars

The Cloud-Native Application Protection Platform, or CNAPP, has become the most contested battleground in cybersecurity. Wiz famously rejected a $23 billion acquisition by Google before striking a $32 billion deal, while Palo Alto Networks, CrowdStrike, SentinelOne, and Datadog are all racing to consolidate security and observability.

Upwind differentiates itself with its runtime-first approach, focusing on real-time context rather than just scanning for vulnerabilities. The company claims its platform can cut alert noise by over 90%, helping security teams focus only on critical threats that are actually exploitable in production.

By staying independent, Upwind preserves a three-way race at the top of the CNAPP market. Expect even fiercer competition for enterprise deals as Datadog will now likely have to build or buy elsewhere to compete.

IPO Ambitions and What's Next

All signs now point to Wall Street. With a $3.8 billion valuation, $400 million in fresh cash, and triple-digit annual recurring revenue growth, Upwind is widely viewed as a prime IPO candidate for late 2027 or 2028.

The startup has reportedly been hiring senior finance and legal executives with public-company experience, and expanding its U.S. go-to-market team aggressively.

Challenges remain. The company will need to prove it can scale efficiently toward profitability while fending off giants with far larger sales forces. But by rejecting Datadog, Upwind's founders have made their intentions crystal clear: they aren't building to sell — they're building to IPO and lead the next era of cloud security on their own terms.
