Stobox seed round, United States: the US round is open. Regulation D 506(c) for verified accredited investors, with D&O coverage secured for the offering.

The US leg of the round is open

The Regulation D 506(c) leg of the Stobox seed round is live. Verified accredited US investors can now review and subscribe through Silicon Prairie, an SEC-registered, FINRA-member broker-dealer, at stobox.sppx.io.

This is equity in Stobox Technologies, Inc. itself, the company that has been building real-world-asset tokenization infrastructure since 2018. It is not an offering of the client projects tokenized on our platform. The valuation, share class, price, minimums, financials and full risk factors are set out in the official offering documents on the portal, which is where they belong and where they stay current. The round overview lives at invest.stobox.io.

For eligible non-US investors, the separate on-chain path through STBX remains live at stbx.stobox.io, under its own documents and its own eligibility rules.

We also secured TigerMark

Alongside the offering, Stobox has secured TigerMark, a Directors and Officers (D&O) and securities-liability insurance policy. It is administered by Assurely, an Equal Parts company, and underwritten by Great American E&S Insurance Company and Relm Insurance, Ltd. The coverage attaches to this offering and incepts when the round closes.

TigerMark exists because conventional D&O underwriting was built for companies with a handful of institutional shareholders, not for issuers running a regulated offering in public with a broad base of investors. It is written specifically for companies raising under JOBS Act exemptions: Reg CF, Reg A+, and Reg D 506(c).

What it covers, in plain terms: claims brought against the company and its directors and officers. An investor alleging that funds were misused or that the offering documents contained a material misrepresentation. A regulatory action or investigation. A breach-of-fiduciary-duty allegation. The policy responds to those claims, subject to its own terms, conditions and exclusions.

What it deliberately is not

We want to be precise here, because insurance is the easiest thing in capital markets to oversell.

TigerMark does not insure your investment. It insures the company and its officers against covered claims of wrongful conduct. It pays nothing because a business underperforms, because a valuation falls, or because a private security stays illiquid. There is no principal protection here, no downside guarantee, and no reduction of market risk. Early-stage equity remains high risk, including the risk of total loss, and nothing about this policy changes that.

It is also not an endorsement. A carrier underwrote a risk and priced it. Nobody approved, recommended or passed upon this offering: not Great American, not Relm, not Assurely, not Silicon Prairie, and by law not FINRA and not the SEC. We hold this line on every third-party relationship we have, whether it is a broker-dealer’s due-diligence clearance or an industry membership. A commercial relationship is never validation.

So why do it? Because it is a governance choice, and we think it is the right one. Underwriters ask hard questions before they take a risk, disclosure discipline improves when a carrier is reading your offering documents, and the founders and officers who sign those documents should not be personally exposed for good-faith decisions. That is the same standard we ask of the issuers we work with. It would be strange to skip it on ourselves.

Take part, or see the rails working

For verified accredited US investors: the offering is live at stobox.sppx.io. Review the documents in full, including the risk factors, before you decide.

For eligible non-US investors: the STBX path is open at stbx.stobox.io, under its own terms.

For issuers and asset owners: every mechanism in this round runs on the infrastructure we sell. If you want your own raise to work this way, see Stobox Compass or talk to our team.


This article is general information about Stobox and an announcement that the offering described is open. It is not an offer to sell or a solicitation of an offer to buy any security, and it is not investment, legal, tax, or insurance advice. The Regulation D 506(c) offering is made only to verified accredited investors, only through the official offering documents on the Silicon Prairie portal, and only where permitted by law. STBX is a separate offering to eligible non-US investors under its own documentation and is not available to US persons. Securities involve a high degree of risk, including total loss, and are illiquid and transfer-restricted. Insurance coverage is described here in summary only; the TigerMark policy insures the issuer and its directors and officers, not any investor’s capital, and is governed exclusively by its own terms, conditions, retentions and exclusions. Neither the SEC nor FINRA nor any state securities regulator has approved or passed upon this offering. Review the offering documents in full and consult your own advisers before making any decision.
