Remote-First-Company | NEW YORK CITY – September 3, 2025 – VAST Data, the AI Operating System company, has been named to the prestigious 2025 Forbes Cloud 100, the definitive ranking of the top 100 private cloud companies in the world, published by Forbes in partnership with Bessemer Venture Partners.
Securing the #24 spot on the 2025 Forbes Cloud 100 highlights VAST’s momentum and leadership within the AI and cloud ecosystem. The evaluation considered several core metrics, including:
VAST has proven its long-term, independent growth with a high-margin business model - remaining cash flow positive for 4+ years, and recently experiencing 5x YoY sales growth in FY25, on top of a 2023 valuation of $9.1 billion.
Bessemer Venture Partners (BVP) introduced the Rule of X in January 2024. VAST’s current Rule of X is 551% – astoundingly, a near 3.5x increase from the company’s 162% Rule of X in 2024.
In the last year, VAST has achieved a verified Net Promoter Score (NPS) of 84 - the highest in the industry. This world-class achievement serves as a testament to the deep satisfaction and loyalty of VAST’s customers.
The VAST AI OS is the first platform built from the ground up to manage the complete AI lifecycle, consolidating storage, database, and compute runtime into one unified foundation. With a global namespace that spans private, public, and emerging neoclouds, VAST enables enterprises to harness all of their data seamlessly while providing the core infrastructure for those next-generation AI cloud service providers worldwide. By standardizing on VAST as their AI operating system, these providers are accelerating and democratizing AI deployments, from GenAI model training to inference and agentic workflows.
Earlier this year, Forbes also recognized VAST on the 2025 Forbes AI 50 List, which honors the top privately-held companies developing the most promising business use cases of artificial intelligence.
We’re honored to once again be recognized on the Forbes Cloud 100, highlighting VAST’s leadership at the intersection of cloud and AI,” said Renen Hallak, Founder and CEO of VAST Data. “This distinction validates VAST’s mission to build the AI Operating System that powers the next generation of intelligent systems. As organizations embrace agentic AI at scale, VAST provides the foundation to turn massive data sets and accelerated computing resources across global hybrid multi-cloud environments into real breakthroughs that transform industries. This acknowledgment reflects not just what we’ve built so far, but also the massive opportunity ahead as AI reshapes every part of our economy and society.
For the tenth consecutive year, the Cloud 100 reviews submissions from hundreds of cloud startups and private companies each year. The Cloud 100 evaluation process involved ranking companies across four factors: market leadership (35%), estimated valuation (30%), operating metrics (20%), and people & culture (15%). For market leadership, the Cloud 100 enlists the help of a judging panel of public cloud company CEOs who assist in evaluating and ranking their private company peers.
For the last decade, the Forbes Cloud 100 list has recognized the most innovative private cloud companies in the world, and this year’s standouts are among the most impressive we’ve ever seen,” said Richard Nieva, the Forbes editor of the Cloud 100. “Our honorees highlight the massive sea change that AI has brought to the enterprise, with sky-high growth and valuations.
As we mark the 10th year of the Cloud 100 with our 2025 rankings, we celebrate a highly competitive cohort of companies that, for the first time, collectively exceed $1 trillion in value,” said Elliott Robinson, partner at Bessemer Venture Partners. “The cloud is in a period of rapid, AI-driven transformation, with this year’s cohort demonstrating how AI is fundamentally reshaping how the best cloud companies grow, scale, and compete.
