Prove a document was never altered — evidence an outsider can verify.

The problem

When a record's integrity is questioned — in an audit, a dispute, or a courtroom — "our system logged it" is exactly what fails. Almost every tool proves integrity with its own audit log, kept by the same company that could change the record. That is self-attestation, not proof.

What I do

• Tamper-evident records. Each record's cryptographic fingerprint is anchored to public blockchains — Vaulta for an instant proof receipt, Bitcoin (via OpenTimestamps) as the long-term backstop — so any later change is detectable.
• Independently verifiable. Integrity can be checked by an outside party — a regulator, a court, a claimant, your own board — without trusting me or you.
• No lock-in. Open, standard formats and public chains. If ReportProof disappeared tomorrow, the proofs you already hold would still verify.
• Fits your process. A record you keep, with proof you can hand to an auditor, a regulator, or a court.

Where it fits

The same primitive — a record whose integrity anyone can verify — fits wherever "prove it wasn't changed" matters:

• Legal & evidence — contracts, e-discovery, digital chain of custody.
• Audit & inspection reports — prove a report wasn't backdated or edited after the fact.
• Compliance records — from ESG and sustainability claims to whistleblowing (EU Directive 2019/1937).
• Financial & insurance — statements, claims evidence, before/after photos.

Built by one engineer — and that's the point

ReportProof is built and run by one person: me. That's deliberate, and it's to your benefit. When a record's integrity is the entire product, you want to reach the engineer who designed the cryptography — not a salesperson who relays your question to a junior. No account managers, no hand-offs, no "let me check with the team." The person who answers your hardest question is the one who wrote the code. More about how I work →
