Oxide bets on the cloud you own; $200M Series C, then a $445M Form D
Rack-scale on-prem 'cloud computer' sold outright: $200M Series C in Feb 2026, then a $445M SEC Form D; customers include Jane Street and a national lab.
Oxide Computer Company
What the business is
Designs and manufactures the Oxide Cloud Computer, a rack-scale system combining compute, storage, networking and open-source software that delivers a public-cloud-style, API-driven experience inside an on-premises data center.
Starting capital：$200M Series C in February 2026 led by Thomas Tull's US Innovative Technology Fund, with Eclipse, Riot Ventures and Jane Street participating; a subsequent $445M Form D offering — $444,999,052 sold to 15 investors, first sale 2026-07-20 — filed with the SEC on 2026-08-04.
How it started
Founded by Steve Tuck and Bryan Cantrill, veterans of Sun Microsystems and the Joyent cloud startup, who argued the on-prem market had been abandoned to an eight-vendor DIY stack or renting from hyperscalers. They set out to build the entire cloud computer, hardware and software, as one product.
What happened
After years of engineering the Hubris OS and open firmware, Oxide brought the Oxide Cloud Computer to market and in June 2026 announced it would leverage colocation at CoreSite's SV2 Silicon Valley data center. In February 2026 it closed a $200M Series C led by Thomas Tull's USIT; in July 2026 it sold $445M in a new round disclosed in an SEC Form D — more than double the Series C — signed by president Steve Tuck on 2026-08-04.
How it ended up
Still scaling: the $445M raise gives years of runway to expand manufacturing and customer support for enterprises planning projects measured in decades; publicly discussed customers include Jane Street and a national lab, and Oxide itself had not confirmed the shape of the round beyond the Form D as of September 2026.
Background
Oxide Computer Company builds the Oxide Cloud Computer, a rack-scale system that fuses compute, storage, networking and open-source software into one product sold outright for on-premises data centers. Founded by Steve Tuck and Bryan Cantrill, veterans of Sun Microsystems and the Joyent cloud startup, the company attacked the two options enterprises were stuck with: a fragile eight-vendor DIY stack, or renting from hyperscalers with lock-in and egress bills.
The bet is that a meaningful set of buyers — high-frequency trading shops, national labs, sovereignty-sensitive organizations, anyone who cannot put data on someone else's hardware — want the speed and APIs of the public cloud on machines they own. Oxide's wedge is a single integrated rack with hardware root of trust, open-source firmware, two-hour setup and no subscription licensing, pitched as 'the cloud you own' at roughly half the cost.
After closing a $200M Series C in February 2026 led by Thomas Tull's USIT, Oxide deployed at CoreSite's SV2 data center and unveiled its commercial Cloud Computer in June 2026. On 2026-08-04 an SEC Form D disclosed a $445M round — $444,999,052 sold to 15 investors, first sale July 20 — more than double the Series C, drawing 198 comments in a Hacker News front-page thread about whether on-prem 'cloud ownership' is becoming a real category.
What has to be true
- Public-cloud API convenience plus on-prem ownership resolves the sovereignty, cost and lock-in objections that disqualify hyperscalers for sensitive buyers.
- A single integrated rack kills the eight-vendor finger-pointing and licensing overhead of traditional on-prem stacks.
- Customers like Jane Street and national labs buy on decade horizons, so demonstrated long-term funding is a core purchasing criterion.
- A $445M round more than doubling the Series C signals the category is real — and raises the bar for any would-be clone.
What can be applied
Capital intensity is a moat when customers plan decade-long infrastructure bets: a bigger balance sheet is itself the sales pitch, because buyers must believe the vendor will outlive the contract.
Aftermath
As of 2026-09-02, the SEC Form D shows Oxide Computer Co raised $444,999,052 from 15 investors in an offering that began 2026-07-20, filed by president Steven Tuck on 2026-08-04. The company has not disclosed the round's lead, valuation or whether it is a Series D. Oxide continues to deploy racks at CoreSite's SV2 facility, expand manufacturing and court customers with decade-long commitments, and the Hacker News community treats the raise as validation of the on-prem 'cloud ownership' thesis.
