About us
The company that exists because banks stopped helping.
01 · Origin
How it started.
2017 — New York, NY
In 2017, Seth Farbman needed a Medallion Signature Guarantee. He'd been a customer at Sterling Bank for twenty-five years. They said no.
"Seth wasn't a typical customer. He's a securities lawyer and the owner of V Stock Transfer — an SEC-registered transfer agent. He knew exactly what a Medallion guarantee was, why it was needed, and how straightforward the process should be. And his own bank still wouldn't help.
That experience became the foundation for eSignature Guarantee. Seth partnered with Yoel Goldfeder, another securities lawyer, to build a company that would solve this problem for everyone facing the same frustration.
Over the next eight years, they issued 25,000+ stamps, built a compliance framework from scratch, and established relationships with every major transfer agent in the country.
02 · The next chapter
A new owner.
July 2025 — Acquired by Jess Heron
In July 2025, Jess Heron acquired eSignature Guarantee. The goal: take a company that already works and make it faster, simpler, and easier to use.
The foundation is solid — 25,000+ stamps, an established compliance framework, and relationships with every major transfer agent. What's changing is the technology and the experience: a rebuilt platform, fewer steps, clearer guidance on exactly what you need before you start.
Why a fintech operator
Jess spent a decade at Ripple, Circle, and Pivotal building infrastructure that makes complex financial processes accessible. The medallion guarantee process is exactly the kind of problem that technology should have solved years ago.
The compliance expertise that makes a stamp legitimate — Christina, Aileen, and the review team — is the same team that has been reviewing requests since long before the acquisition. What's new is the product around it.
03 · The team
Built to last.
A focused team, organized by function — compliance, case management, support — so the people reviewing your documents can give each one the attention it deserves.

04 · What we believe
Three principles.
This process is hard enough already.
People needing Medallion guarantees are often grieving, stressed, and unfamiliar with the requirement. We don't add friction; we remove it.
Expertise earns trust.
Reassurance comes from competence, not promises. We set clear expectations and meet them.
Build what should exist.
The securities transfer industry has standards. We're not inventing something new. We're building what should have existed all along.
05 · Regulatory standing
Credentials, not promises.
eSignature Guarantee is an authorized participant in the Securities Transfer Agents Medallion Program (STAMP) — one of the three recognized Medallion Signature Guarantee programs under SEC Rule 17Ad-15. Our guarantees are accepted by all major transfer agents nationwide.
We carry professional errors & omissions insurance and are bonded to protect both our customers and the institutions that rely on our stamps.
