Most companies shouldn’t build their own foundation models, at least that’s what Poolside CEO Jason Warner believes. But Onyx’s co-founder and co-CEO, Chris Weaver, sees things differently. He envisions Onyx as a foundational tool for enterprises looking to build internal search products, tackling a challenge many companies still struggle with: finding the right information when they need it.
The enterprise search space is already fiercely competitive, with players like Glean and Swirl leading the charge. Yet, despite the rapid advancements in AI, businesses continue to wrestle with the complexity of extracting value from their internal data. Employees waste time searching across vast company repositories like Salesforce, GitHub, Google Drive only to come up empty-handed. Onyx aims to fix that.
Weaver and his co-founder, Yuhong Sun, weren’t strangers to startup failures. Their earlier ventures, a live stats tracker for Twitch streamers and a keyboard comparison site never took off. But the duo saw a recurring issue in their engineering roles: information was scattered, hard to find, and even harder for new employees to navigate.
