I'm Benoit, a CEO based in Kyoto. I built ClientsOK because I was frustrated with the current state of e-signatures. I needed to timestamp and secure IP/contracts frequently, but existing solutions like DocuSign were either too expensive ($45/mo for features I barely use) or lacked true forensic permanence (if the platform dies, the proof often dies with it).
ClientsOK is my attempt to solve this with a "forensic-first" approach.
The Architecture: Instead of just placing an image of a signature on a PDF, we treat the document as a digital evidence package:
Fingerprinting: We generate a SHA-256 hash of the final document.
Context Capture: We record 14 points of metadata during the signing event (IP geolocation, precise timestamp, device info, browser fingerprint).
Anchoring: We anchor the hash on the Bitcoin blockchain. This ensures that the proof of existence and integrity is verifiable independently of my startup, forever.
Legal & Compliance: The generated certificates are compliant with eIDAS (EU) and the E-SIGN Act (US).
Pricing: We offer a free tier (1 doc/month, 2MB limit) to let people test the tech. The Pro plan is $9/mo (vs ~$45 for competitors). There is also a public API for developers to automate certification ($0.50/doc).
I'd love your feedback on the signing flow and the technical approach to the audit trail.
Thanks!
