Oxide Computer Co, a Delaware corporation headquartered at 1251 Park Ave. in Emeryville, California, and incorporated more than five years ago, has disclosed a $444,999,052 equity raise in a Form D notice filed with the U.S. Securities and Exchange Commission. The notice states the total offering amount and the total amount sold are both $444,999,052, with $0 remaining to be sold, meaning the round is fully subscribed. Fifteen investors have already put money in. The first sale in the offering took place on 2026-07-20, and the notice itself was signed and submitted on 2026-08-04 by Steven Tuck, listed as the company's President.

The offering claims the Rule 506(b) exemption under Regulation D, and the security type is Equity. The filing reports $0 in minimum investment accepted from any outside investor, $0 in sales commissions, $0 in finders' fees, and $0 of the gross proceeds paid to any person named as an executive officer, director or promoter. The company checked "Other Technology" as its industry sub-category, rather than the more specific "Computers" or "Telecommunications" options on the form, and it declined to disclose its revenue range.

The notice names five related persons at the company. Steven Tuck and Bryan Cantrill are both marked as Executive Officer and Director. Seth Winterroth and Gaetano Crupi are marked as Directors only, not Executive Officers. Scott Orn is marked as an Executive Officer only, not a Director.

Beyond these disclosures, the filing does not name any of the 15 investors, does not identify a lead investor, and states no valuation for the company. It does not describe what Oxide Computer does, its products, or what the funds raised will be used for beyond the standard Form D questions on payments to officers, directors and promoters, all of which it reports as zero.

Key facts

  • Oxide Computer Co's SEC Form D shows a $444,999,052 equity offering, fully sold, from 15 investors, with $0 remaining to be sold.
  • President Steven Tuck signed the notice on 2026-08-04; the first sale in the offering was dated 2026-07-20.
  • The offering used the Rule 506(b) exemption under Regulation D; the filing reports $0 in sales commissions and $0 in finders' fees.
  • Five related persons are listed: Steven Tuck and Bryan Cantrill as Executive Officer and Director, Seth Winterroth and Gaetano Crupi as Directors only, and Scott Orn as Executive Officer only.
  • The filing names no investors, states no valuation, and does not describe the company's business or the intended use of the funds; it declined to disclose a revenue range.

Why it matters

A Form D notice is a company's own disclosure that it has closed a private securities offering, and this one puts a specific figure on Oxide Computer's latest raise: $444,999,052 in equity, fully sold to 15 investors as of the filing date. Because the amount sold equals the total offering amount and nothing remains open, the round reads as closed rather than still fundraising.

Who it affects

The filing formally involves Oxide Computer's own officers and directors: Steven Tuck (President, Executive Officer and Director), Bryan Cantrill (Executive Officer and Director), Seth Winterroth and Gaetano Crupi (Directors), and Scott Orn (Executive Officer). It does not name the 15 investors who put money into the round, so their identities and any board or governance changes that may follow are not disclosed here.

How to use it

This is a regulatory notice, not a product announcement, so there is nothing to buy, license or price. Its practical use is as a public, dated record confirming the size and closing status of the raise; it is filed with the SEC under Regulation D and does not require the company to publish a prospectus or a valuation.

How solid is it

The figures come directly from the primary source: the Form D itself, signed by President Steven Tuck under a filing that carries federal criminal liability for misstatements (18 U.S.C. 1001). The SEC does not verify the content, and the numbers are entirely self-reported by the company rather than independently audited.

Risks and caveats

The filing is deliberately narrow. It gives no valuation, no investor names, no lead investor, and no stated purpose for the funds beyond confirming that none of it went to sales commissions, finders' fees, or payments to the company's own officers and directors. It also does not describe what Oxide Computer does or declare a revenue figure, having marked 'Decline to Disclose' on that question, so the raise cannot be read against the company's financial performance.
