Dated proof, without the upload

Eureqa proves a file existed at a given moment, without the file leaving the creator’s device.

Pre-seed stage · MVP live on staging

The problem

Creators and their lawyers must show who had a work first, and when, without handing over the file. A “poor man’s copyright” envelope proves little; a bare blockchain stamp has no legal presumption in the EU; US registration costs $45–85 and takes about four months.

WIPO PROOF, the closest precedent, stopped new issuance in 2022. Our lesson: a timestamp alone is not a business. It needs legal weight, a workflow and B2B buyers.

The product

How a proof is made Four steps. On the device: SHA-256 and SHA3-256 fingerprints are computed in the browser and only the fingerprints leave. Signed by the creator with a passkey. Timestamped twice: a qualified EU timestamp under eIDAS plus Bitcoin as an independent witness. Proof package: one self-contained file, designed to be checked without Eureqa. On the device SHA-256 + SHA3-256 in the browser; only fingerprints leave. Signed by the creator Passkey approval: face, fingerprint or screen lock. Timestamped twice Qualified EU timestamp (eIDAS), plus Bitcoin as independent witness. Proof package One self-contained file, designed to be checked without Eureqa.

Each package has six layers: fingerprint, signature, qualified timestamp, Bitcoin anchor, long-term validation data and US declaration templates (FRE 902(13)/(14)).

Why now

Market, bottom-up

No sourced top-down figure exists for this niche, so the plan is built from funnel, conversion and churn. Under conservative assumptions, at end-2032: 13,800 paying individuals (visual artists first, independent musicians second), 3,100 small firms (IP law, agencies, publishers) and 235 API accounts.

Business model (planned)

Planned prices in USD, to be validated in Phase 0.

Paid ads do not pay back for individuals (acquisition about $137); they grow through shareable verification pages. Team/Legal lifetime value is well above acquisition cost.

Target gross margin about 75% at scale (assumption).

Go-to-market

People cannot demand something they cannot yet imagine. Our first job is to make creators realise they need this.

Founder’s thesis

So awareness comes first: content, communities and the verification-page loop.

Regulatory path

EU: the legal presumption comes from the qualified timestamp (eIDAS Art. 41(2)); proofs are signed with the user’s passkey. GDPR: the file stays on the device; we process two fingerprints and account data. US: packages include FRE 902(13)/(14) templates, and the offer rests on Copyright Office filing, not on the blockchain.

Phase 3 (Ethereum record, co-ownership record) needs a licensed partner and opinions under Howey, FINMA and MiCA. A Phase 2 utility token is planned and will be issued when the beta starts; it is not a financing instrument; issuance follows legal review (MiCA, US securities).

Quarterly profitability from Q3 2028. 2032: revenue $20.5M, EBITDA $11.6M.

Valuation and use of capital

Use of capital: product and engineering 25%, go-to-market 23%, legal and compliance 21%, founder and operations 20%, security reviews 3%, reserve 8%.

Legal and compliance (21%), first item: legal counsel in every target jurisdiction (EU, US, Switzerland) on the evidentiary standing of digital signatures and timestamps, plus token and co-ownership structuring.

This capital funds: Phase 0 exit criteria (500+ waitlist sign-ups, 30% of interviewees already spending on the problem, 10% pre-order clicks), company formation, legal opinions, a timestamp provider contract, external code review, paid open beta and first B2B customers.

The Phase 1 test (at least 1,000 paying users or about $117k ARR (€100k)) gates the next round. Company to be incorporated in the United States (Delaware).

Roadmap

Phases: 0 validation (interviews, waitlist) · 1 proof package (open beta, GA) · 2 token · 3 Ethereum record and co-ownership record (licensed partner).

  1. Q4 2026Company, opinions, contracts, closed beta
  2. Q1 2027Paid open beta; token (with the beta)
  3. Q2 2027Launch in the EU, US and Switzerland
  4. Q3 2027Team/Legal and API plans
  5. Q2 2028Phase 1 test: 1,000 payers or about $117k ARR (€100k)
  6. H2 2028Phase 3: Ethereum record, co-ownership pilots (licensed partner)
  7. 2029SOC 2 and ISO 27001

Risks and mitigations

Demand: the closest precedent closed.
Phase 0 exit criteria, priced waitlist, quarterly decision gates, early shift to B2B.
Solo founder; most code awaits human review.
Second maintainer and external code review before beta.
Regulation: evidentiary weight varies by country.
Opinions in target jurisdictions before beta; a licensed partner for Phase 3; the US offer rests on Copyright Office filing.
Timestamp provider: no contract yet.
A primary and a backup provider; API pricing indexed to timestamp cost.

The plan assumes a paid open beta on 1 January 2027, which is aggressive; under conservative assumptions, a one-quarter slip cuts 2027 revenue from $0.14M to $0.08M.
