Paragon

Paragon is an integration infrastructure platform that gives AI agents and SaaS products a single way to connect to the tools their users already run, so builders do not have to write and maintain a custom integration for every third party app. Founded in 2019 in Los Angeles by Brandon Foo and Ishmael Samuel, the company came up through Y Combinator and has raised more than twenty one million dollars from investors including Inspired Capital, Y Combinator, Global Founders Capital, Soma Capital, and Village Global. It has grown more than ten times in recent years and now backs the integrations of hundreds of customers and more than one hundred engineering teams, including AI companies like Copy.ai.

Paragon frames modern integration as four pillars and is now positioned as the only infrastructure platform to cover all of them: Tools, Triggers, RAG ingestion, and Workflows. Its ActionKit product exposes more than a thousand prebuilt actions across one hundred thirty plus connectors through a single API or a Model Context Protocol server, letting an agent dynamically pick and run the right action in a user's Salesforce, Slack, Jira, or Google Workspace. ActionKit Triggers, launched in public beta in 2026, adds the event driven layer so agents know in real time when something happens in a connected tool. Managed Sync indexes a user's files and records into a vector database for retrieval, and a low code Workflows builder handles broader automations.

The platform is deliberately model and framework agnostic, plugging into any large language model or agent framework such as the Vercel AI SDK or LangChain, and its ActionKit MCP server is publicly listed on Anthropic's MCP registry. A managed Connect Portal handles secure OAuth and API key authorization for each end user, and the whole system can run in Paragon's cloud or be fully self hosted for teams with strict data requirements. For a company building an AI agent or SaaS product that needs deep, user facing integrations without a large integrations team, Paragon is a category leading option; a team that only needs one or two integrations may find a direct API simpler.
