Executive Overview
In a striking demonstration of confidence in the booming artificial intelligence cybersecurity sector, San Francisco-based cloud security startup Upwind has successfully closed a massive $400 million Series C funding round. The latest capital injection values the four-year-old enterprise at an impressive $3.8 billion, marking a meteoric rise for a company that was valued at just $1.5 billion a mere nine months prior.
The financing round was led by Bessemer Venture Partners, with strong continued participation from existing high-profile backers, including Greylock Partners and Craft Ventures. However, the headline-grabbing figure is only part of the story. Behind the scenes, this blockbuster financing nearly collapsed after a multi-billion-dollar corporate acquisition swoop by publicly traded observability giant Datadog.
According to sources close to the transaction, Datadog made a concerted play to acquire Upwind outright. Because Datadog’s acquisition proposal failed to offer a meaningful premium above the $3.8 billion valuation already established by its venture capital syndicate, Upwind’s leadership team ultimately decided to pass on the buyout. By choosing to remain independent, Upwind is betting heavily on its unique "runtime" cloud security framework, explosive annual recurring revenue (ARR) growth, and the broader macroeconomic thesis that cybersecurity will form the third massive wave of enterprise spending on artificial intelligence software.
This in-depth report examines the chronology of Upwind’s meteoric rise, the dramatic behind-the-scenes acquisition talks with Datadog, the financial metrics underpinning the company’s $3.8 billion valuation, and what the future holds for a startup that is fast becoming one of the most talked-about entities in the global tech ecosystem.
Detailed Chronology: From Founding to a $3.8 Billion Independence Play
The Genesis Under Amiram Shachar
Upwind was founded four years ago by serial entrepreneur Amiram Shachar, whose track record in the cloud ecosystem precedes him. Shachar previously founded Spot.io (formerly Spotinst), a cloud spend and infrastructure management startup that he successfully scaled and ultimately sold to NetApp in 2020 for $450 million.
Leveraging his deep technical expertise in cloud infrastructure, Shachar established Upwind to tackle what he identified as a critical blind spot in modern cloud security: the gap between static code vulnerabilities and active, real-time runtime threats. While traditional security tools often scan code repositories or configurations before deployment, Upwind pivoted toward "runtime" security. This approach actively monitors, alerts, and remediates attacks and vulnerabilities on active cloud services in real time, giving enterprise security teams an unprecedented window into live environments.
The Hyper-Growth Phase
Over the past 24 months, Upwind has transitioned from an early-stage challenger into a dominant force in cloud security, accelerated largely by the rising tide of AI-driven cybersecurity threats. Enterprises migrating complex workloads to multi-cloud environments have increasingly found themselves targets of sophisticated, automated attacks. Upwind’s runtime security framework has resonated deeply with chief information security officers (CISOs) looking for real-time visibility rather than post-mortem diagnostics.
The company’s financial velocity over the past year has been nothing short of staggering:
- January 2026: Upwind closes a $250 million financing round at a $1.5 billion valuation, led by top-tier venture firms to expand its runtime cloud security capabilities.
- Fall 2026: Preparations begin for the company’s next major capital raise, intended to institutionalize its market leadership and fuel international expansion.
- Late 2026: The $400 million Series C round is finalized at a $3.8 billion valuation, led by Bessemer Venture Partners.
The Datadog Acquisition Drama
The road to Upwind’s $400 million Series C was fraught with unexpected corporate intrigue. According to individuals familiar with the transaction, the financing round—which had been quietly in the works for months—nearly fell apart at the eleventh hour due to an aggressive acquisition approach from Datadog.
Datadog, a massive publicly traded titan specializing in software monitoring and observability tools, sought to swallow Upwind to fortify its own security and infrastructure offerings. As cloud observability and cloud security continue to converge into a unified operational discipline, acquiring a hyper-growth asset like Upwind would have given Datadog an immediate technological moat.
However, negotiations hit a wall over valuation. Datadog reportedly attempted to acquire Upwind at the exact valuation set by the venture capital investors: $3.8 billion. Failing to offer a substantial acquisition premium above the market-rate VC valuation, Datadog’s bid failed to sway Upwind’s board and founders. Confident in their trajectory and quarterly financial gains, Upwind’s leadership rejected the buyout offer, electing instead to take the $400 million in primary capital and preserve the company’s independent roadmap.
Despite walking away from Datadog’s advances, sources indicate that Upwind continues to draw significant acquisition interest from other industry players, reflecting its prime positioning in the current tech landscape.
Supporting Context & Financial Metrics
To understand why Upwind commanded a $3.8 billion valuation—and why Datadog was willing to throw its hat into the ring—one must examine the startup’s stellar financial fundamentals and the broader macroeconomic climate surrounding AI-driven enterprise software.
Revenue Velocity and ARR Projections
Upwind’s valuation is backed by aggressive, predictable revenue expansion. According to insiders privy to the company’s financials, Upwind has consistently added between $20 million and $30 million in annualized recurring revenue (ARR) each quarter.
The startup is projected to close the current fiscal year at roughly $90 million in ARR. Evaluating this against the $3.8 billion valuation yields an ARR multiple of slightly more than 40x. While a 40x multiple is historically high by traditional equity standards, it is increasingly common in the upper echelons of high-growth cybersecurity and AI infrastructure.
To put Upwind’s multiple into perspective, it sits well below the staggering 80x ARR multiple commanded by Cyera, another high-flying cybersecurity startup that made headlines earlier this year when it eyed a $12 billion valuation despite ongoing operating losses. Upwind’s blend of explosive growth and disciplined capital efficiency makes its 40x multiple appear remarkably grounded relative to its hyper-growth peers.

+--------------------+------------------------+---------------------+The Third Wave of AI Software Spend
The broader tailwinds propelling Upwind forward were recently dissected by Tomasz Tunguz, general partner at Theory Ventures, in a widely read industry analysis. Tunguz posited that enterprise software adoption is moving through distinct, generational waves of artificial intelligence willingness-to-pay:
- First Wave: AI coding assistants and developer productivity tools (e.g., GitHub Copilot).
- Second Wave: AI customer support and automated service operations.
- Third Wave: Cybersecurity software powered by AI.
As artificial intelligence begins to write code, deploy applications, and manage workflows autonomously, the attack surface expands exponentially. Traditional human-speed security tools are fundamentally inadequate for combating automated, machine-speed cyber threats. Consequently, enterprises are eagerly allocating unprecedented budget lines toward AI-native security platforms like Upwind. This macroeconomic thesis explains why venture capital syndicates are willing to pour hundreds of millions of dollars into runtime security infrastructure at multi-billion-dollar valuations.
Official Statements and Industry Reactions
As news of the $400 million financing round and the aborted Datadog acquisition attempt reverberated through Silicon Valley, media outlets and industry analysts sought formal responses from the key stakeholders involved.
TechCrunch reached out directly to both Upwind and Datadog for comment regarding the acquisition talks and the details of the Series C round. At the time of publication, neither company has issued a formal public statement addressing the specifics of the buyout discussions.
Industry observers, however, have been vocal:
- Venture Capital Perspective: Backers from Bessemer Venture Partners, Greylock, and Craft Ventures view the $400 million round as a validation of Upwind’s technological moat. By rebuffing Datadog, Upwind’s investors are signaling that the company has a clear path toward becoming a standalone category leader rather than an absorbed feature set within a larger legacy platform.
- Market Analysts: Financial analysts note that while remaining independent carries execution risks—particularly given the notoriously volatile public market windows for tech IPOs—the sheer volume of inbound acquisition interest proves that Upwind holds critical leverage.

Future Outlook: IPO Horizon or Inevitable Acquisition?
Looking ahead, Upwind stands at a fascinating crossroads in its corporate lifecycle.
The Independence Dilemma
By walking away from Datadog’s $3.8 billion purchase offer, Upwind’s leadership has placed a massive bet on its own future. The core premise is straightforward: as runtime security becomes a non-negotiable requirement for cloud-native enterprises, Upwind’s top-line revenue will continue to scale rapidly, pushing its intrinsic value far past the $3.8 billion mark by the time it eventually accesses public markets or entertaining future acquisition bids.
The M&A Reality Check
Despite the bold stance on independence, industry pragmatists point out a stark market reality: very few pure-play cybersecurity companies have successfully gone public in recent years. Regulatory hurdles, macroeconomic uncertainties, and the stringent disclosure requirements of public markets have made the initial public offering (IPO) path treacherous for mid-to-late-stage startups.
Consequently, financial analysts widely agree that an eventual strategic acquisition remains the most statistically probable exit outcome for Upwind. The only variables are when that acquisition will happen and who the ultimate buyer will be. With Datadog having tested the waters—and other major cloud infrastructure giants closely watching Upwind’s growth trajectory—competition among prospective acquirers is likely to intensify.
Summary of Strategic Priorities for Upwind
- Scaling Runtime Defense: Continuing to refine real-time threat remediation algorithms to outpace evolving AI-driven cyber attacks.
- Geographic and Enterprise Expansion: Deploying the $400 million war chest to capture enterprise market share across North America, Europe, and Asia-Pacific.
- Talent Acquisition: Attracting top-tier engineering and cybersecurity talent to maintain its technological edge over legacy monitoring incumbents.
Conclusion
Upwind’s $400 million Series C round is more than just a massive financial milestone—it is a statement of intent. In a market where many startups eagerly cash out at the first sight of a multi-billion-dollar acquisition offer, Upwind has chosen to bet on itself. Backed by elite venture capital firms, fueled by an impressive $90 million ARR run rate, and fortified by a cutting-edge runtime security architecture, Upwind is well-positioned to weather market storms and redefine how the digital world secures its cloud infrastructure. Whether it ultimately charts a course toward a public market debut or commands an even higher acquisition price tag down the road, Upwind has firmly established itself as a heavyweight champion in the new era of AI-driven cybersecurity.
