SIGNiX

SIGNiX provides digital and electronic signatures with remote online notarization, backed by twenty years in business, more than a billion digital signatures and ten patents.

Ten patents is an unusual figure in this category and reflects genuine technical work rather than a wrapper around someone else's signing infrastructure. Combined with two decades of operation, it indicates a company that built the cryptography rather than licensing it.

The technical position is that every signature is cryptographically sealed and tamper-evident. In practice this means the signature is embedded in the document itself and verifiable independently, so a signed agreement remains provable years later without depending on the vendor still existing or still holding an audit log. For long lived agreements such as loan documents or estate paperwork, that independence is a substantive difference from platforms where proof lives on the vendor's servers.

Two product routes are offered. E-Signatures suits businesses of any size wanting documents signed online immediately, and Flex API provides a richer feature set for companies building an integrated digital signature product into their own software. SIGNiX combines bank-grade security with built-in compliance and a signing experience it describes as one customers actually enjoy, serving individual entrepreneurs through to global corporations. Pricing is published from 180 dollars.
