How It Works

01

Create a room

Name your exchange, add the parties, and set the rules. Takes 30 seconds.

02

Links sent by email

Each party receives a unique, encrypted submission link directly via email.

03

Simultaneous release

Documents are released to all parties at the same time. No one sees first.

Why Sealed.

Every simultaneous exchange currently relies on trust. Someone has to go first, or both sides rely on a human intermediary to collect and release.

That works until it doesn't. A missed email. A delayed release. A question about whether one side had an unfair advantage.

This tool replaces that uncertainty with a system that holds submissions in encrypted escrow and releases them the moment all parties have submitted.

It cannot read your documents. It cannot play favorites. It follows the same rules every time, for every party.

Built by professionals who got tired of gamesmanship.

What each party sees

Three steps. Three clean screens. The other party clicks a link, uploads, and they're done.

Exchange Report (PDF)

Works everywhere the order matters.

From courtrooms to boardrooms. Any exchange where going first means giving something up.

Legal submissions

Simultaneous briefs, expert reports, and settlement offers in arbitration and litigation.

Sealed bids

Collect proposals from multiple vendors or contractors. Reveal all at once.

Salary negotiations

Both sides submit their number. No anchoring. No advantage.

M&A and deal terms

Exchange term sheets simultaneously so neither party sets the anchor.

Mediation and dispute resolution

Position statements submitted to the neutral at the same time.

Peer review

Reviewers submit evaluations independently before seeing each other's assessments.

Ready in 30 seconds.

Create a room, share the links, and both sides submit on their own time. No accounts. No passwords. No learning curve. The other party just clicks a link and uploads.
