Important mail should be sealed.

Signet7 is the trust layer for consequential email. Signet7 can seal the email. Then verify the seal. Keep the record. Then pick up the phone. An agent can use that same record later. Look up whether that company listed this address.

The mission

Give important email a cryptographic seal, then a check before action.

Ordinary-looking email can now move money. Signet7 is the last look before you act, and the record you keep.

PlatformSignet7 is the trust layer for consequential email.
The emailAn important message is the moment you pause before money moves.
Look up a companyListed, Not listed, or Listing doesn’t match this address.
The name

The seal is on the message. You can show later that the words still matched.

You put a seal on a letter so it can still be proven years later, when an auditor, partner, or court asks what you received.

You need to know it is authentic.

Was it bound to who they claim? Do the protected words still match?

You need proof of exactly what you received.

Keep the result. Produce it when they ask.

Founding roles

Clear operating responsibilities.

George Terris II

Founding Team Member — marketing.

Governance boundary: these are working role descriptions for a pre-formation project. They do not independently create officer titles, legal authority, ownership, compensation, signature authority, or economic rights.
How the team works

Product direction and product evidence stay separate.

01

Define precisely

State the product goal, coverage profile, trust assumptions, user result, and managed trust infrastructure without letting future-state language become a current capability claim.

02

Build and test

Implement versioned contracts, negative cases, lifecycle behavior, provider transformations, evidence handling, and operational controls.

03

Release with proof

Promote only after technical, security, privacy, legal, operational, and claim owners accept the exact statement and supporting evidence.

Current stage

Live today, with more on the roadmap.

The live check and company accounts are available now. DNS keys if they published TXT. Hosted listings on the company desk after they enroll, not a public directory. Not a phone book of every company.

The codebase also includes action-bound signatures, sender/key trust resolution, narrow fail-closed policy, HTTP/MCP decisions, signed decision chronology, portable evidence, and the s7-email-1 protected-message profile.

Direction-specific policy, universal tool interception, durable managed sender custody, and the complete public listing network remain on the roadmap.
