Onyx is building an open source application layer designed to make large language models (LLMs) accessible to enterprises. The company's primary product, the Onyx Open Source AI Chat Platform, connects to a company's internal documents, applications, and personnel to provide instant, grounded answers. It employs techniques such as hybrid search, advanced Retrieval-Augmented Generation (RAG), contextual retrieval, and LLM-based knowledge graphs, and supports Model Context Protocol (MCP), code execution, and custom AI agents. The platform is trusted by over 1,000 teams.
As an alternative to self-hosting, Onyx also offers Onyx Cloud, a hosted version of its enterprise AI platform. The company's work spans technical domains including AI agents, knowledge graphs, and enterprise AI security, with compliance certifications such as SOC 2 Type II.
Onyx is backed by Y Combinator, with investment from partners at Khosla Ventures and First Round Capital. Its customers range from startups to large enterprises across sectors like enterprise software, knowledge management, and collaboration tools.
