Our solution

AI that is safe, effective and sovereign, for public services

1Safe

It follows your protocols rather than the model's defaults, cites its sources line by line, and your experts validate it before it goes live.

2Effective

It is measured in production, on field results: time given back to teams, faster answers for the public, compliance tracked over time.

3Sovereign

It runs on your infrastructure, with your data, in open source. You can take over at any time.

The problem

Generic AI wasn't built for public & social services

Millions of people depend every day on frontline professionals. But commercial AI wasn't built for them.

It doesn't know their protocols.
It can't protect sensitive data.
It hallucinates when it matters most.

Who we are

The leading nonprofit for AI in public services

We believe AI can help solve the capacity gap between the number of people who need help and those on the frontlines. This is why we partner with public services and NGOs to build AI agents that address societal needs. Founded in Silicon Valley in 2014.

Introducing the Bayes Platform

The first open-source AI agent platform built for public services. Here is what it does, in the real product.

01
Model-agnostic
Model-agnostic

The agent is tied to no model and no supplier. Changing either means retesting and recalibrating the harness, with no business logic to rewrite, and open models remain an option when the case calls for one.

02
Infrastructure you control
Infrastructure you control

Managed cloud or your own infrastructure, from a single Docker image. The retention period is yours, health data is hosted on HDS-certified infrastructure, and your data never trains a third-party model.

03
An open-source commons
An open-source commons

The code is MIT-licensed: you deploy it, change it, and keep it if Bayes disappears. What one institution funds benefits the next, with no licence to buy.

04
Your sources, your protocols
Your sources, your protocols

The agent answers from your handbooks, protocols and official references, never from the open web. Every answer cites the document and the extract it used, and the platform enforces your rules when the model skips them.

06
Governed by your teams
Governed by your teams

Your frontline teams create and tune their own agents, with no code. Every change writes a draft, and nothing reaches the public that a human has not published.

07
Tested before it goes live
Tested before it goes live

Evaluation campaigns replay conversation and extraction datasets against a chosen version. Reviewers rate the answers blind, an LLM judge gives the scale, and two runs compare side by side.

08
Continuous improvement
Continuous improvement

Every exchange is filed under the life situations you defined, and the topics your answers cover badly surface on their own. You complete the corpus, re-evaluate and publish: the agent improves with every version.

09
Plugged into your tools
Plugged into your tools

Each agent is exposed over API and MCP, an open standard: the assistant or portal your institution already runs calls it as a tool. A widget or a public page when that is simpler. Nobody changes screen.
