TreasOS is non-custodial software for corporate Bitcoin treasuries. We give boards and operators policy, approvals, and audit evidence—while the client keeps the keys, signs offline, and broadcasts themselves.
Bitcoin is appearing on European balance sheets. Operating it like a treasury asset is still mostly improvised: chats, spreadsheets, ad-hoc multisig, or full exchange / custodial stacks that introduce counterparty and CASP complexity.
After MiCA’s full application, boards and auditors increasingly ask for segregation of duties, spend policy, and an evidence trail. Custodians solve vaulting. They do not automatically give a CFO-grade, self-hosted control plane that stays clearly outside custody.
TreasOS is a watch-only treasury operating system: organization and roles, spend policies, maker-checker approvals, PSBT workflows, UTXO visibility, fee context, proof of reserves (BIP-322), and an audit / auditor path. The platform never holds seeds or private keys and does not co-sign.
Deployment is self-hosted or EU-hosted. Spain / France builds keep regulatory-sensitive modules off by default (no yield product surface, no managed “we broadcast for you” story as the core offer).
Europe’s listed Bitcoin treasury sector is smaller and more fragmented than the US archetype, but the operational pain is the same: once BTC is material, governance becomes a board issue. Buyers who refuse exchange custody need software that matches that posture.
We run an education demo on regtest and an institutional pilot stack on testnet. Separately, we completed a founder-operated Bitcoin mainnet end-to-end smoke on a LAN deployment: watch-only wallet, maker-checker outbound, offline PSBT signing, platform broadcast, and change tracking—without public internet exposure of the stack.
That does not mean we have a paying customer or a signed commercial pilot. It means the core mainnet path is no longer theoretical. The raise is to convert that into a paid design partner, an EU legal vehicle, and an external security review.
Beachhead: European Bitcoin treasury / holdings companies and similar corporates or family offices that need multi-approver controls. Channel: MiCA counsel, auditors, and Bitcoin strategy advisors who already sit with those boards.
Commercial motion: paid technical pilot → enterprise license/subscription. No freemium on customer infrastructure.
We do not pitch against late-stage custody platforms on valuation. Our competitors are (1) manual process and (2) custodial SaaS that a European board may reject on principle. Multisig vault products solve a related but vault-first problem; TreasOS is treasury orchestration first.
Entity in motion, pentest scoped or underway, and at least one serious LOI or paid pilot conversation with a beachhead-profile buyer. The product proof for mainnet ops already exists; the capital buys commercial and institutional packaging.
