About Diodorus

We build the governing body for the AI agents companies run.

Diodorus builds Nexus. It deploys agents and tools to each team, defines how they are built and what roles they play, and holds all of them to the same rules.

Why we started

AI arrived in companies team by team, with no rules in between.

Not through one decision or one standard, but through dozens of small ones. By the time anyone looks at the whole picture, three things are already true.

Cost

No one can name the number

Model calls multiply across teams, and the total only appears on an invoice.

Data

No rule on what reaches a model

Sensitive information flows through agents nobody reviewed before they went live.

Record

Nothing to go back to

When something goes wrong, no log says which agent, which model and which data drove it.

How we build

We build the control layer first, the channels last.

Most products are built from the outside in: pick a channel, wire up an agent, ship a result. A governing body is built the other way around. The rules, the cost caps and the audit trail exist before the first team is let in.

What we believe

What we believe about AI inside a company.

Four principles behind Nexus. They apply on every deployment.

Control speeds teams up

With governance in place, the second team starts on day one instead of rebuilding the rules.

Every call has a price and an owner

AI cost should be visible per team before the invoice arrives, not reconstructed after it.

The audit trail is what makes an agent trustworthy

If no one can say which data drove a decision, that agent should not be in front of a customer.

No single vendor

Models change every quarter. Route each task to the model that fits it, including open source you host yourself.
