On-premises cloud computing provider Oxide Computer Company has raised $100 million in a Series B funding round.

Known for its rack-scale compute offering, Oxide's latest funding round was led by Thomas Tull’s US Innovative Technology Fund (USIT) and saw participation from all existing investors.

The funding more than doubles Oxide's total capital raised to date and will be used to scale manufacturing, expand customer support, and speed up the company's delivery roadmap.

“This round gives us the ability to scale confidently and sustainably in step with accelerating customer growth,” said Steve Tuck, CEO and co-founder of Oxide. “Our customers want the agility of the public cloud without giving up control, and they want to know their infrastructure partner is built to last. With this raise, we’re deepening our commitment to delivering a long-term solution that meets those needs head-on.”

Oxide launched its on-prem cloud computing rack system in November 2023. The rack system can have 16, 24, or 32 compute sleds and 16-32 processors with x86 cores. The compute sled is made up of AMD Epyc 7713P processors and uses Intel Tofino 2 switches.

“From the outset, we knew that delivering the cloud experience on-prem required more than mere integration – it demanded first-principles thinking and hardware/software co-design,” said Bryan Cantrill, CTO and co-founder of Oxide.

“We rethought the entire stack, from the physical computer itself and its lowest levels of firmware through the hypervisor, control plane, and programmable switch – and designed a unified system that eliminates the complexity, fragmentation, and vendor finger-pointing that enterprises have long had to endure. Our approach is fundamentally different – and our customers are experiencing the benefits of end-to-end security, power efficiency, and operational agility.”

Oxide was founded in 2019 and is based in Emeryville, California. In November 2024, the company revealed it would be deploying its rack-scale computer at the Lawrence Livermore National Laboratory (LLNL) high-performance computing center.

The company also counts the Idaho National Laboratory among its customers, and has deployed its racks at a CoreSite data center in Silicon Valley.
