Visionaries Behind NVIDIA, Meta, Palantir, SpaceX and Tesla Now Betting on Hammerspace

SAN MATEO, Calif.–(BUSINESS WIRE)–Hammerspace, the high-performance Data Platform for AI, today announced that several strategic venture investors, who were early backers of transformative companies like NVIDIA, Meta, Palantir, SpaceX and Tesla, have invested $100 million in new strategic growth capital in Hammerspace.

This is not a typical venture round. Altimeter Capital, ARK Invest, and other hand-selected strategic investors are participating not just for returns—but for the opportunity to drive the next era of AI infrastructure. These partners bring more than funding. They bring strategic insight, deep sector experience, and an active commitment to our long-term success.

Data performance has evolved from a competitive edge to a requirement in the race to scale AI infrastructure. Hammerspace delivers that edge across every dimension of unstructured data: storage, access, movement, and deployment. Whether training thousands of GPUs on-premises or in the cloud, deploying large-scale inference or maximizing NVMe performance in local GPU servers, Hammerspace is purpose-built to unleash data performance at scale.

“AI isn’t waiting. The race isn’t just about raw throughput—it’s about how fast you can deploy, move data and put your infrastructure to work. Every delay is unrealized potential and wasted investment,” said David Flynn, Hammerspace Founder and CEO. “We built Hammerspace to eliminate friction, compress time-to-results and significantly increase GPU utilization. That’s how our customers win.”

The Investors Betting on Performance at Scale

Altimeter Capital, which identified industry shifts early with investments in Meta, MongoDB, NVIDIA, Snowflake and Uber, led the Series B round.

“Hammerspace understands that AI is only as powerful as the data it can reach,” said Jamin Ball, Partner at Altimeter Capital. “Its architecture removes the bottlenecks that are starving today’s most advanced compute environments.”

ARK Invest, led by Cathie Wood, joined the round through its ARK Venture Fund. Known for its conviction-based investing in disruptive technology companies—including early bets on Tesla, NVIDIA and Palantir—ARK sees Hammerspace as foundational to the performance infrastructure AI demands.

The remainder of the funding round was filled out by a combination of new and existing investors. Early investors identified Hammerspace as a disruptive force in data infrastructure well before AI workloads reshaped enterprise, hyperscaler and cloud priorities. With demand for high-speed, scalable access to data now surging, existing supporters continue to invest in Hammerspace to support its expansion into a fast-growing market.

The Next Era of Data Infrastructure

Global technology leaders, including Hitachi Vantara (a subsidiary of Hitachi Ltd., HTHIY) and Supermicro (SMCI), are building solutions on Hammerspace’s software for customers like Meta, the U.S. Department of Defense, the National Science Foundation, and major life sciences organizations. These deployments demonstrate a new standard in performance across hybrid, multi-cloud, and edge environments—without complexity or vendor lock-in.

Hammerspace gives organizations a Linux-native, standards-based, parallel file system and object store that delivers unmatched performance across file and object protocols using standard Ethernet or high-speed interconnects like InfiniBand. The platform uniquely overcomes data gravity by combining instant data-in-place assimilation from other sources with high-speed movement across hybrid environments – all in the service of delivering peak performance everywhere.

“Performance has always been the starting point, but how you deliver it at scale is what separates the next generation of platforms from legacy infrastructure,” continued Flynn. “Everything we’ve built—from the metadata engine to deployment architecture to protocol support—maximizes performance in any environment.”

Hammerspace stands apart as the first platform built entirely around the performance needs of modern computing. From unmatched GPU throughput to instant access across file and object data to deployment time measured in minutes—not weeks—every capability of the platform is designed to remove bottlenecks, maximize speed and deliver scale.

“We didn’t build orchestration for the sake of it,” Flynn said. “We orchestrate data to the GPU faster regardless of where it is physically stored. We instantly assimilate data from third-party storage so it’s ready to process faster. We deploy and scale easily and quickly so our customers can achieve their business outcomes faster. We are the only AI data platform that enables Tier 0, providing the absolute fastest performance for AI workloads, bar none. Hammerspace uniquely approaches performance holistically from time to first token through the entire model’s response. It is a game-changer for our customers and the industry.”

With this latest investment, Hammerspace will accelerate global expansion and deepen its position as the performance platform of record for AI, HPC and hybrid cloud environments.
