About EndorsedSign
We build the signing layer other businesses run on — so their customers never leave the product to sign.
What we build
Signing infrastructure for platforms
EndorsedSign is an eSignature layer that other products embed. Your customers see your brand. We handle multi-party workflow, audit, delivery, and compliance.
White-label by design
Every signer surface — portal, notifications, signing domain — can carry your name and colours. We disappear into your product.
Built for defensibility
The audit trail is hash-chained, append-only, and designed to stand up under review. Every signing event is recorded with timestamp, IP, and correlation ID.
API-first from day one
REST API, webhooks, React embed component, and headless SDK. The same workflow available in the portals is available over HTTP from day one.
Where we work and how we build
Amsterdam and Tel Aviv
The team splits between Amsterdam and Tel Aviv. We are small, async-first, and move fast on a focused product scope.
Partners help shape what ships
Partner teams are in the product loop. We take integration feedback seriously — real deployments expose edge cases that internal testing does not.
We say what we ship
The changelog, compliance page, and comparison page state what is live now. We do not backfill marketing copy with future state.
You own the relationship
We do not contact your customers. You set who signs, in what order, under what brand. Completed files live in your tenant — not ours.
