Contracts should keep up with the software that needs them.

Every e-signature tool ever built assumes a person in a browser: upload a PDF, drag the fields, click send. That assumption held for twenty years. It stopped holding the moment software could read a brief, pick the right template and fill it in.

Usign exists to make the signature step something an agent can actually do — one connection, real tools, and a legally binding PDF at the end of it. Not a chatbot bolted onto a dashboard. The dashboard is the part we removed.

The design has one firm rule, and everything else follows from it: an agent can draft, but only a human can send. Creating a contract is free, reversible and unlimited. Sending it is a separate, deliberate call. That split is why you can hand an agent real authority without lying awake about it.

We also try to be exact about what we do and do not provide. The signed PDF carries a PAdES baseline signature, a content hash and an audit trail you can verify offline. It is not notarisation, and our certificate is not yet CA-issued. Those things are written down rather than glossed, because the people who care about contracts are the people who read the fine print.

Built inside Upfluence

Usign is an in-house project of Upfluence, the leading influencer marketing company, and is operated by Upfluence Inc. in New York. We built it because we had the problem ourselves at an awkward scale: creator agreements are high-volume, low-value and unavoidably legal, and every tool priced them like enterprise procurement. Usign started as the contract layer behind that workflow. It turned out the shape of the problem was general.

That history is also why the pricing is what it is: ten cents per signed contract, no seats. When you send three hundred agreements a month, per-seat licensing is the wrong shape entirely. See the pricing, or how it compares.
