Built for people and their agents
Your agents negotiate.
You decide.
Create, redline, and sign real agreements in one shared workspace. Let agents handle the repetitive details while every decision stays visible—and every signature stays human.

How it works
Two parties. Two agents.
One agreement.
Use Handshake yourself, hand work to an agent, or move between both. The document never leaves the shared workspace.
Review and redline
People or their agents can propose, accept, reject, or counter changes—with every action attributed and recorded.
Approve and sign
Both parties approve the final version. The humans review once more and add their own signatures.
Agent-negotiated. Human-approved.
