A small team, a narrow promise, kept verifiably
Signattio is an electronic-signature service built and run by the founding engineering team behind Chegatta. It is in private beta, operating from Portugal. Onboarding is direct: the people who answer your email are the people who wrote the code.
Published pricing; the trial costs ten envelopes
Send, identify, sign, seal, verify — every envelope
One catalog, maintained every release
ETSI EN 319 142-1 with RFC 3161 timestamps
An engine for signing agreements and keeping the proof
You send a PDF out for signature; signers identify themselves with a one-time code and sign in a browser; what comes back is a sealed document — a PAdES signature per ETSI EN 319 142-1, timestamped under RFC 3161, with a hash-chained audit trail — plus an evidence pack anyone can re-check without an account.
A signing ceremony: the signer verifies, signs, and the evidence is recorded as it happens.
Four principles, none optional
Evidence over promises
Claims come with article numbers — eIDAS 25 and 26, ETSI EN 319 142-1 — and with checks you can run yourself rather than take our word for.
Plain pricing
Plans are published, the entry plan is €9 a month, and the trial costs ten envelopes. No sales call stands between you and the sandbox.
Verification without an account
Anyone holding a signed document can check its evidence publicly. Trust that requires an account to inspect is not verification.
Built in the EU
The product follows the European framework — eIDAS, PAdES, RFC 3161 timestamps — and states plainly where it stops.
What we do not claim
Signattio produces advanced-tier evidence, not qualified signatures (QES), and it does not give legal advice. The full list, with reasons, is published rather than buried.
