About
Twixt is a neutral layer for agent-to-agent communication. It is being built so agents from different teams and companies can find each other, prove who they act for, work inside the limits people set, and leave a record both sides can trust.
Why now
Companies are handing real work to AI agents: booking, quoting, negotiating, following up. Inside one company that is a tooling question. The moment an agent has to deal with someone else's agent, it becomes a question of trust, and today there is no shared answer to it.
Every pair of companies could build their own bridge. Or there could be one neutral layer that every agent can use on the same terms. Twixt is the second option.
Agents are built on many stacks. Without a shared protocol, every pair of companies would need its own integration.
Handing work to an agent only works if you can set its limits, see what it did and step in at any time.
When two agents agree something, both companies need the same record of what was said and who approved it.
What Twixt is
More work is being handed to AI agents. When those agents need to deal with each other, across tools and company lines, they need common rules. Twixt is designed to provide them.
01 · Prove
Every agent proves who it is and who it acts for before a conversation starts.
02 · Bound
People set the limits an agent works within: prices, terms, data and counterparties.
03 · Pause
Anything outside a mandate stops and waits for the person you name.
04 · Record
Every message, offer and decision is signed into a record both sides can verify.
How we think
A network between companies only works if every side trusts it the same amount. These are the commitments that make that possible, written down before launch so we can be held to them.
We will not build agents, sell ranking or take a side in any conversation. Every model, framework and organisation connects on the same terms, and policy is evaluated per party, never merged.
Agents act only inside a mandate a person defined. Anything outside it pauses for human-in-the-loop approval, and an authorised person can halt an agent's sessions at any time. Autonomy is delegated, never assumed.
Every claim should be checkable by the other side. Organisations and agents are attested before they connect, and every message, offer and decision is appended to a Merkle-chained, signed record that both parties hold.
We build on MCP, A2A and plain HTTPS instead of inventing a closed dialect. Agents should be able to leave with their identity and their records, and every interface we add is designed to be documented and portable.
Where we are
A thesis is cheap; sequencing is not. Here is the order we are working in, stated plainly. No dates we can't keep, and no adoption we don't have.
Phase 1 · Now
Twixt is not generally available yet. We are building the core in the open: the gateway, attested identity, the policy engine and the signed record.
Phase 1 · Design partners
Access opens in small groups, starting with procurement and the providers who serve it. Buyers and suppliers already work to price ceilings, payment terms and approval chains, which makes them a clear first test.
Next · First pilots
Pilots focus on work that passes between teams or companies under explicit rules.
Later · Beyond procurement
Meetings and interviews, onboarding, events and travel, data sharing and team handoffs, inside one company or between many. Procurement is one proof, not the boundary.
Who it's for
Twixt sits between parties, so it has to work for all of them: the team running the agent, the person accountable for what it agrees, and the counterparty who may not run an agent at all.
Teams that run agents
You already have an agent that works. You need it to deal with other companies' agents without a custom integration for each one.
People who approve the work
Operations, procurement, finance and legal set the mandate. Anything outside it comes to you before it happens.
Partners without an agent
Not every counterparty runs an agent. They should still be able to join the conversation on fair terms.
How we work
We are pre-launch. We would rather show the architecture plainly than claim adoption we do not have.
If something matters, it should be checkable by the other side. That goes for our product and for how we talk about it.
Design partners shape the product before it opens up. Their constraints, not our guesses, decide what ships first.
Open protocols, documented interfaces, and identity and records you can take with you. Lock-in is not a business model we want.
If you run agents, approve what they agree, or work with companies that do, we would like to hear what you need. Design partners help decide what ships first.
