AI infrastructure company VAST Data closes a $1B Series B at a $30B valuation, tripling its prior figure, with Nvidia among returning investors.
VAST Data's $30 billion valuation didn't come from a chatbot or a foundation model. It came from selling the infrastructure those models run on.
The company closed more than $1 billion in a Series B round, pushing its valuation to $30 billion, more than triple its prior figure. Nvidia, an existing investor, participated alongside other returning backers. Yahoo Finance covered the news Friday in an interview with CEO Renen Hallak, who framed the raise as a bet on where the artificial intelligence buildout goes next.
Hallak's explanation for investor enthusiasm is direct: the AI stack moves through phases. Power infrastructure came first, then chips. Now comes the software layer that makes AI deployable inside large enterprises facing compliance and regulatory requirements. Building that layer is VAST's business.
The Rule of 40 number
One metric stands out from the interview. VAST Data's Rule of 40 score, which sums revenue growth rate and profit margin as a quick health check for software companies, sits at 228. A score of 40 is the conventional baseline for a healthy software business. A score above 100 is considered exceptional. Claiming 228 means VAST is growing very fast while simultaneously generating strong margins, a combination rare enough to command serious investor attention. Capital from the round will go toward internal development rather than acquisitions, Hallak said, though no specific product roadmap was disclosed.
Who VAST is competing against
The Yahoo Finance segment named three publicly traded companies in the competitive frame: NetApp, Pure Storage, and Dell. All three have pivoted into AI-adjacent positioning. VAST's argument is that those incumbents were designed for a pre-AI era and their architectures don't suit the data workloads that large language models and autonomous agents generate. That pitch is familiar in infrastructure cycles, where new compute paradigms tend to outpace legacy vendors long enough for a faster entrant to plant roots. What's different now is pace. As Forbes has observed, the AI investment wave has compressed technology cycles from years into months.
The larger context
At $30 billion, VAST sits well below the headline numbers. CNBC reported earlier this year that OpenAI's latest round valued it at $840 billion. Infrastructure companies compete on different terms than model companies. Their value proposition is switching costs and enterprise lock-in rather than research velocity, and once a storage layer is embedded in production systems that touch sensitive records, replacing it carries serious operational risk.
That dynamic is VAST's real pitch to regulated industries: compliance and security built into the layer where model inference meets enterprise data. As Digital Watch Observatory has noted in covering the broader AI commercialization challenge, deploying AI at enterprise scale requires more than capable models. It requires compliant, auditable plumbing. Nvidia's position as an investor sharpens the picture: the chipmaker has clear incentives to back companies that make GPU clusters practical inside the regulated enterprises it wants as customers.
Enterprise artificial intelligence adoption has been widely promised and unevenly delivered. If production deployments accelerate through 2026, VAST is positioned in exactly the right layer. If they stall, a $30 billion valuation will need defending in a market that hasn't fully materialized yet.
FAQ
Q: What does VAST Data do?
A: VAST Data builds data management and storage software designed for AI workloads, targeting enterprises in regulated industries that require security, compliance, and auditability.
Q: Who participated in VAST Data's $1 billion Series B?
A: Existing investors including Nvidia joined the round. A complete list of backers has not been publicly disclosed.
Q: What is Rule of 40, and why does a score of 228 matter?
A: Rule of 40 adds revenue growth rate and profit margin as a quick health check for software businesses. A score of 40 is healthy; above 100 is exceptional. VAST's 228 signals simultaneous rapid growth and strong margins.
Q: How does VAST Data compete with NetApp, Pure Storage, and Dell?
A: VAST argues its platform was built from the ground up for AI-era data workloads, while those incumbents are adapting storage architectures designed before large language models existed.
