VAST Data – Founders, Business Model, Funding & Competitors

VAST Data stands as one of the most remarkable success stories in enterprise technology, transforming from a startup founded in 2016 to a $9.1 billion valuation powerhouse that has fundamentally reimagined data infrastructure for the AI era. The company has achieved what many consider impossible in enterprise software: hypergrowth combined with profitability, maintaining positive cash flow for over five consecutive years while achieving annual growth rates of 2.5x to 3x. VAST Data represents more than just a storage company—it has created an entirely new category of AI-first data infrastructure that unifies storage, database, and compute services into a single, scalable platform designed specifically for modern AI and machine learning workloads.

Founding Story and Vision

VAST Data was founded in January 2016 with an audacious mission: to reinvent data infrastructure from the ground up and eliminate the decades-old tradeoffs that had plagued storage systems. The founding team recognized that traditional storage architectures, largely unchanged for over 20 years, were fundamentally incompatible with the emerging demands of AI, machine learning, and big data analytics.

The company’s genesis was rooted in a simple yet revolutionary premise: “challenge everything” about how data systems were designed and operated. When the founders began their journey, AI wasn’t even a mainstream concern—yet they had the foresight to architect a platform that would prove perfectly suited for the AI revolution that followed. This prescient vision has positioned VAST as the data foundation for the $400 billion AI platform opportunity that has emerged in recent years.

Founders and Leadership Team

Revolutionary Technology: The DASE Architecture

VAST Data’s competitive advantage stems from its groundbreaking DASE (Disaggregated and Shared Everything) architecture, which represents a fundamental departure from traditional storage system design. This innovative architecture addresses the core limitations of legacy storage systems that have constrained performance and scalability for decades.

Core DASE Principles

The DASE architecture is built on three revolutionary concepts:

Disaggregation: DASE decouples CPUs from storage devices, allowing independent scaling of compute and storage resources. This eliminates the traditional constraint of maintaining fixed ratios between compute and storage capacity, providing unprecedented flexibility in system design and resource allocation.

Shared Everything: Unlike traditional “shared-nothing” architectures, DASE enables any CPU to access any storage device in the cluster through a high-speed, low-latency storage fabric. This creates a global shared volume that eliminates communication bottlenecks between nodes.

Infinite Scalability: The architecture can scale to tens of thousands of CPUs and exabytes of flash storage, making it suitable for massive-scale data processing requirements.

Technical Innovation

VAST’s technical innovation extends beyond architecture to include V-tree metadata structures that are 7-layers deep, with each layer 512 times larger than the one above it. This structure can support 100 trillion objects while maintaining broad and shallow trees that eliminate the need for cross-talk between compute nodes.

The system employs byte-granular, thin-provisioned, sharded storage with an infinitely-scalable global namespace, enabling efficient resource utilization and simplified management. Deep write buffers allow data to be written in any form before conversion to optimized long-term formats, enabling the system to handle both transactional and analytical workloads seamlessly.

Business Model and Revenue Streams

Gemini Subscription Model

VAST Data operates on an innovative Gemini subscription model that separates hardware from software, fundamentally changing how customers purchase and deploy storage infrastructure. This model provides several key advantages:

Hardware Transparency: Customers license VAST software from VAST while purchasing hardware directly from verified partners like Supermicro, HPE, and Cisco at cost. This approach provides complete cost transparency and eliminates traditional vendor markup on hardware.

Flexible Licensing: VAST delivers licensing based on resources managed by the software: capacity (storage) and compute (CPU cores). This disaggregated model is specifically designed for modern AI workloads and offers flexible license terms that scale independently.

Co-Pilot Services: Every Gemini subscription includes VAST Co-Pilot services, where expert cloud operators monitor customer systems, handle planning and deployment as organizations expand, and manage infrastructure scaling. This white-glove support model ensures optimal performance and reduces operational complexity for customers.

Revenue Model

VAST’s revenue model centers on software subscription sales with customers typically purchasing 4-5 year upfront subscriptions. The model has proven highly successful, with key metrics including:

• Average deal size: Approximately $1 million
• Gross margins: Consistently maintained at 90%
• Customer expansion: Net Revenue Retention (NRR) exceeding 300%
• Large enterprise deals: Multiple customers with over $100 million in commitments

Customer Base and Market Penetration

VAST has achieved remarkable penetration across enterprise markets, serving over 25% of Fortune 100 companies and leading global GPU cloud service providers. The customer base spans diverse industries including:

• Government and Defense: US Air Force, US Department of Energy, and Department of Defense with contracts exceeding $10 million.
• Entertainment and Media: Disney, Pixar, Verizon, and major media studios requiring high-performance content processing.
• Technology: Zoom, ServiceNow, and xAI leveraging VAST for AI and collaboration platforms.
• AI Cloud Providers: CoreWeave, Lambda, and Core42 (G42 company) have standardized on VAST as their foundational data platform.

Funding History and Financial Performance

VAST Data has raised $381 million in total funding across six rounds, with its valuation increasing dramatically from $1.2 billion in 2020 to $9.1 billion in 2023. Reports indicate the company is potentially targeting a $25 billion valuation in its next funding round, reflecting continued strong investor interest in AI infrastructure.

Exceptional Financial Metrics

VAST has achieved the fastest path from $1 million to $100 million ARR in data infrastructure industry history, reaching this milestone in just three years of selling. The company has maintained positive cash flow for over five years while achieving hypergrowth, a rare combination in enterprise software.
