# Cambium AI

> AI-powered market research platform that simulates the U.S. population using synthetic personas built from public data.

Cambium AI transforms millions of public data points into a conversational interface. Users ask questions about the U.S. population and receive structured demographic insights instantly. The platform is designed for market researchers, product managers, marketers, political analysts, social scientists, public administrators, and content creators.

## What Cambium AI does

- Generates synthetic personas representative of U.S. demographic segments
- Answers market research questions using simulated population responses
- Provides demographic breakdowns by age, geography, income, occupation, and more
- Supports use cases including product research, campaign targeting, voter analysis, policy planning, and audience development

## Data methodology

Cambium AI builds synthetic personas from U.S. Census data, public surveys, and other open public datasets. Personas are AI-generated simulations — not real individuals. All insights are probabilistic and intended for research purposes.

## How to interact

Cambium AI is a web-based conversational interface. There is no public API. Users sign in and access the platform at https://app.cambium.ai/signIn

County-level demographic data is also publicly explorable at https://counties.cambium.ai/

Cambium AI also provides a Model Context Protocol (MCP) server for Claude, called the Cambium AI Product Manager MCP. It brings the synthetic population into product decisions inside Claude: persistent business case across sessions, decision log with rationale and population evidence, persona interviews, audience sizing, market and regulatory research.
