Signed. Sealed. Provable.

Signet is e-signing for founders and small teams. Send a contract, proposal or NDA, your client signs it in one tap with no account, and every document is sealed with proof it wasn't changed.

A simpler, better-looking, provable alternative to old e-signature tools.

Why Signet

Three reasons small teams choose Signet.

Designed, not exported

Your documents should look like your brand.

Signet renders documents from your own design, logo, type, layout, into a flawless PDF. Incumbents staple fields onto whatever you upload. Yours looks considered, because it is.

No logins. Just sign.

Your client signs without making an account.

A secure link is the session. Open, review, draw or type, consent, done in under a minute, on any device. No sign-ups, no friction — one tap, no chasing.

Provably untampered

Every signature, sealed and publicly verifiable.

An append-only, tamper-evident audit trail records who signed, when, and from where, and every completed agreement is sealed with a certificate anyone can verify independently, on every plan including Free.

FAQ

Questions, answered.

Yes. Signet is aligned with the EU eIDAS regulation and the US ESIGN Act and UETA, under which electronic signatures carry the same legal weight as handwritten ones. Every completed agreement is sealed with a certificate of completion and a tamper-evident audit trail recording who signed, when, and from where.

A secure link is the session. Your client opens the link, reviews the agreement, draws or types their signature, and consents, done in under a minute on any device. There are no sign-ups, no apps and no passwords, which is the single biggest reason agreements get signed faster.

Signet records every event, opened, reviewed, signed, sealed, in an append-only, tamper-evident audit trail, so any change to the record is detectable. When signing completes, the agreement is sealed with a verifiable certificate. It isn't a log you're asked to trust; it's proof anyone can check.

Signet is built for people who send their own agreements, independent founders, design and creative studios, consultants, agencies and small teams. If you're the one writing the proposal, closing the deal and chasing the signature, Signet makes that last step beautiful, effortless and provable.

Three things incumbents don't give you: agreements rendered from your own design instead of fields stapled onto an upload; no-login signing so clients never need an account; and a provable, tamper-evident seal on every completed document. All at fair, transparent pricing with no enterprise tax.

Documents are encrypted at rest with UK and EU data residency. Your documents are yours, we don't sell them, and we don't train models on them.

There's a free plan for the occasional agreement; Starter at £8 a month (or £80 a year) for your own branding with no watermark; Pro at £14 a month (or £140 a year) for unlimited sends and the designed-template builder; and Team at £26 per seat per month (or £260 a year) for roles, Spaces, approvals, contract lifecycle tracking and the API. Starter and Pro are a flat workspace price; only Team is per seat. During the private beta, early access is free.
