- ESIGN, UETA & eIDAS compliant
- SOC 2 Type II audited
- Trusted by signers in 30+ countries
Why teams build on Signing Hippo
Everything you need to launch a branded signing product.
An e-signing core that has been running in production for years. White-label, compliant, and designed to be the signing engine inside someone else's product.
White-label by default
Your brand, your domain, your colors. Every screen, email, and PDF certificate ships under your name — not ours.
Full stack, not just an API
Mobile apps, web client, backend, and admin — production-ready from day one. You ship the differentiator, not the plumbing.
Compliance is included
ESIGN, UETA, and eIDAS compliant out of the box, with a tamper-evident audit log on every signature.
Embed where your users are
Drop the signing flow into your existing iOS, Android, or web product — or ship a standalone branded app on top.
Court-ready audit trail
Every view, signature, and edit is timestamped, signed, and locked into a verifiable certificate of completion.
Partner, not a vendor
A dedicated integration engineer during rollout and an SLA-backed support team after launch. Real engineers, real Slack.

About us
Why teams build on Signing Hippo.
We've spent the last decade shipping secure document software for hospitals, banks, and law firms — battle-testing every line. Now we license that same core to product teams who'd rather ship a signing experience in weeks than reinvent compliance from scratch.
Built for trust
SOC 2 Type II audited, GDPR-aligned, and independently penetration-tested every quarter.
Partner, not a vendor
Dedicated integration engineering during rollout. Real engineers on your Slack — not a ticket queue.
