E-signature infrastructure for regulated work. Every signer passes an email one-time passcode, and every envelope is sealed with a hash-chained audit trail strong enough for legal, accountancy and property.
Every completed envelope is sealed as a PDF carrying a PAdES digital signature and an RFC-3161 timestamp. Alter one byte and the seal breaks.
A timeline you can read, share by URL and export as a signed PDF. The proof is a surface, not a buried download.
Create, send and track envelopes over a small JSON API; signers finish on a hosted, mobile-first page and a signed webhook tells your app it's done.
Create an envelope, add signers, capture the signature, receive a webhook. The whole SES surface is a small, predictable REST API.

}'A small, portable proof — anyone you hand it to can check it themselves, with no account.
A typed name is easy to dispute. Pactivo puts a one-time passcode on the signer, writes every step into a SHA-256 hash chain, and seals the finished document with a PAdES digital signature and an RFC-3161 timestamp — so the record is checkable, not assertable.

Yes. The Electronic Communications Act 2000 and UK eIDAS both recognise electronic signatures as evidence, and the Law Commission confirmed in 2019 that an electronic signature can validly execute most documents. A few documents have their own formality rules (wills are the usual example), so check what your document needs.
A Simple Electronic Signature (SES) under UK eIDAS, which covers most business documents. Every signer clears a one-time passcode sent to their email before the document opens. Advanced (AES) and Qualified (QES) signatures are on the roadmap.
Every completed envelope is sealed into a PDF carrying a PAdES digital signature and an RFC 3161 timestamp, and every event in its audit trail is hash-chained with SHA-256. Anyone with the document's verification code can check it on a public page, without an account.
No. A signer opens the link in their email, enters the one-time passcode sent to that address, and signs on any device. The flow is designed for a phone first.
Documents, signatures and audit trails are stored and processed in the UK, on Rajoka-operated servers. Transactional email is delivered by Resend, which operates in the EU and the US; the privacy policy sets out the detail.
You pay per envelope, from £0.42 to £0.69 excluding VAT depending on the plan, with no per-seat fees. The pricing page has the detail for each plan.
