What Onyx does
Onyx is a San Francisco-based, venture-backed startup that builds an open-source AI research agent for enterprise workplace search. The product indexes knowledge across more than 40 internal data sources — including workplace tools, document stores, and internal applications — and enables enterprise teams to retrieve information through an agent-style interface. Its core differentiator is the open-source distribution model combined with broad integration interoperability, allowing security-conscious enterprises to self-host, inspect, and extend the technology. The company was founded in 2018 and operates with 11-50 employees.
Onyx's business model is anchored on an open-source core with an enterprise layer built on top. While the open-source version is distributed free of charge, revenue is expected to be generated through enterprise licensing, managed services, or premium support for large organizations. The company's design-partner customer base includes Netflix, Ramp, and Thales Group, spanning entertainment/streaming, fintech, and aerospace/defense. Go-to-market combines product-led open-source distribution with a consultative direct sales motion for enterprise deployment.
In March 2025, Onyx closed a $10 million seed funding round co-led by Khosla Ventures and First Round Capital, with proceeds earmarked for team expansion and product development. The company is led by co-founder Asaf Avidan Antonir and co-founder & CTO James Sha. A prior $1 million round was led by Afore Capital in November 2018.
