Diodorus · Corporate AI

Diodorus builds the governance layer between your teams and the AI models they use.

Most companies adopt AI team by team. Each team picks its own tools, and nobody can say what is running across the company, what it costs or what it reached. Diodorus turns that into one capability the company runs on purpose, and ships it as a product called Nexus.

What a company needs before AI becomes a capability.

Four things have to be true, and they have to be true in this order. Each one is what makes the next one worth anything.

Identity on every call

Every request carries who asked and which application asked, before it reaches a model. Without that, none of the rest can be attributed to anyone.

Cost known before the invoice

Each team works against a budget, and what it has spent is visible while the work is happening rather than at the end of the month.

Rules that run before the model, not after

Guardrails check a request on the way in and stop the ones that break a rule. A check that runs afterwards is a log, not a control.

A record of every execution

Each run is written down: the agent, the model, the tools it called and what it cost. When someone asks what happened, there is an answer.

What Diodorus does.

We build the governance layer, deploy it to your teams, and stay on it with you.

We build Nexus

Nexus is one entry point for every AI agent in the company. Access, cost, security and history are managed in one place, across multiple models, connectors and skills.

We deploy it to your teams

A team gets the agents, roles and rules already in place, through the channels it already uses. There is no separate rollout for the second team.

You talk to the founders

Every first conversation is with one of the founders. You tell us where AI is used in your company, and we show you how Nexus would govern it.

Nexus separates who executes, who defines and who enforces.

The product is organised in three branches. Each has its own scope, and none of them can override the other two.

Executive

The agents and tools deployed to each team, executing its tasks and processes day to day.

Legislative

Where skills and tools are built and each agent role is defined, versioned in Git.

Judicial

The protocols and guardrails that bound every team's agents, checked on every run.

Questions we are asked about Corporate AI and Nexus.

Short answers. The longer version of each one is on the product page.

What is Corporate AI?

Corporate AI is artificial intelligence a company runs as one shared capability, rather than as tools each team adopts on its own. In practice that means a single entry point for every agent, identity and permissions on every model call, a budget per team, rules that run before a model is reached, and a record of every execution.

What does Diodorus do?

Diodorus builds the governance layer between a company’s teams and the AI models they use, and deploys it to those teams. The product is called Nexus. It was founded by Marcelo Prado and Thiago Valente.

What is Nexus?

Nexus is the governing body for the AI agents a company’s teams use. 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. It works with multiple model providers, caps cost per team and records every execution.

Who is Nexus for?

Companies whose teams already use AI and need one place to control access, cost, data and history. Nexus deploys to the teams that already exist: finance, sales and customer success, operations, engineering, and people and legal.

Which model providers does Nexus work with?

Nexus is multi-model by default and routes each task to the model that fits it, including open source a company hosts itself. Nothing is tied to a single provider, and swapping a model does not mean rebuilding an agent.

What does Nexus record about each run?

Which agent ran, which model it called, which tools it used, which guardrails were checked, what it cost and how it ended. Every action of every agent is recorded, with a full, searchable history for whoever needs to ask.
