VAST Data

From problem to solution: storage built for the speed accelerators demand

VAST Data was founded in January 2016 by Renen Hallak, Shachar Fienblit, Jeff Denworth and Alon Horev. A large accelerator cluster is the most expensive item in a data center, and every second an accelerator waits for data is a direct loss. Traditional storage systems were designed for large files read in sequence, not for millions of small files read in random order. On this basis the company built a flash-based data layer called DASE (Disaggregated Shared Everything), designed from the ground up to break the usual trade-off between scale, simplicity, performance and resilience.

From storage alone to an "operating system for AI"

Over the years the company expanded the product from storage alone into a platform that combines data, compute and real-time processing in one system. Today it calls this the VAST AI Operating System. According to its official announcement, the platform now supports AI environments spanning millions of GPUs around the world, and its customers include CoreWeave, Lowe's, the U.S. Air Force and Cursor.

The Nvidia partnership: from the CoreWeave contract to Series F

In November 2025 Calcalist reported a $1.17 billion commercial agreement with the cloud provider CoreWeave. Nvidia itself is also an investor in the company: according to VAST Data's official announcement of the Series F round, Nvidia is among the existing investors that took part in the round, alongside Fidelity Management & Research and NEA.

Series F: $1 billion at a $30 billion valuation

In April 2026 the company officially announced that it had completed a Series F round at a valuation of $30 billion. That is more than three times the $9.1 billion valuation set in its previous round at the end of 2023. The round was led by Drive Capital, with Access Industries as co-lead. The round, which included both the sale of new shares and the sale of shares by existing shareholders, reached a total of about $1 billion. According to the same announcement, the company passed $4 billion in cumulative bookings and ended the previous fiscal year with more than $500 million in Committed Annual Recurring Revenue (CARR) and positive operating margin, a combination it described as a "Rule of X" score of 228%. "We are already supporting AI environments spanning millions of GPUs globally, operating across every layer of the AI stack," said Renen Hallak, founder and CEO of the company, in the announcement.

What a private company's valuation really means

A private company's valuation is set in a funding round between the company and its investors. It is not a market price like a share on the stock exchange; it reflects those investors' expectations at a particular point in time. Rounds of this size took place in 2026 against the background of an unusual wave of investment in AI infrastructure. VAST Data's rise to become the most valuable private company in Israel was also made possible by the sale of Wiz to Google, which greatly increased the appetite for numbers like these.
