LemonLime

LemonLime is a San Francisco company (Y Combinator, Summer 2026) building what it calls the AI knowledge layer for business — infrastructure that structures a company's documents, processes, customer history, and institutional knowledge into a foundation frontier models (GPT, Claude, Gemini) can retrieve and reason against. The platform connects to existing business systems (CRMs, document stores, ticketing, communication, and finance tools) over the Model Context Protocol (MCP), builds a structured representation of how the business operates, then deploys role- and workflow-specific AI agents on top of it, routing routine work to small fast models and reserving frontier reasoning models for tasks that need them. It is deliberately model-agnostic so the foundation survives frontier model generations. LemonLime does not train on customer business data on any plan, offers optional zero-data-retention, and markets compliance-aligned deployments for regulated industries. It sells a packaged SaaS product to non-technical teams and publishes no public developer API, SDKs, or API documentation as of this profile.

LemonLime is profiled on the APIs.io network. Tagged areas include Company, Artificial Intelligence, Knowledge Management, AI Agents, and Workflow Automation.

LemonLime’s developer surface includes support, engineering blog, pricing, signup flow, and 17 more developer resources.
