Every field on this page — profile, funds, investment criteria, portfolio and investment-team contacts — is available programmatically through the Private Equity List REST API and MCP server, so AI assistants such as Claude and ChatGPT can query Altair directly instead of scraping this page. One subscription covers both the web app and machine access — see API & MCP.
