Onyx is revolutionizing enterprise search with its open-source model, enabling seamless integration and community-driven development. Co-founders Chris Weaver and Yuhong Sun aim to empower businesses by transforming how they access and utilize their internal data.

In the bustling tech landscape of Silicon Valley, where innovation is as common as coffee shops, a small startup named Onyx is quietly making waves with its open-source approach to enterprise search solutions. In an era where data is the new currency, finding the right piece of information amidst a sea of internal data is a challenge that countless enterprises face.
Onyx, however, believes it has cracked the code.
At the helm of this ambitious venture are co-founders Chris Weaver and Yuhong Sun, who are no strangers to the entrepreneurial grind. Their journey, marked by a series of pivots and lessons learned from past ventures, seems to have found its groove with Onyx.
They both experienced firsthand the frustration of navigating complex data landscapes in their previous engineering roles, sparking the idea for a more intuitive internal search tool.
While the market is crowded with heavyweights like Glean, which has raked in a whopping $600 million in venture funding, Onyx is betting on its open-source model to differentiate itself. This approach not only democratizes access to their solution but also fosters a community-driven evolution of their product.
Companies can effortlessly integrate Onyx within half an hour and connect it to over 40 internal data sources like Salesforce, GitHub, and Google Drive—a feat that traditional enterprise solutions often struggle to achieve without lengthy sales cycles and high costs.
The decision to go open source was not just a technical choice but a strategic one. Weaver asserts, “Open source is really the only way for this type of solution to scale out and get the momentum into every single business in the world.”
This philosophy has resonated with numerous industry giants, including Netflix, Ramp, and Thales Group, who have become part of Onyx’s growing user base.
The road to success, however, has not been without its challenges. Weaver and Sun’s first venture—a live stats tracking app for Twitch streamers—met an untimely demise when Twitch shut down embedded streams.
Their subsequent project, a site for comparing specialty keyboards, also didn’t gain traction. But these setbacks only fueled their determination.
With advancements in AI and Sun’s machine learning expertise, Onyx, initially launched as Danswer, quickly gained momentum after its 2023 debut.
The startup’s organic growth is evident. Sun notes, “We’ve seen the usage grow explosively,” citing a peak of over 160,000 messages in a week.
Such metrics are not just numbers; they are a testament to the tool’s utility and the potential it holds for enterprises worldwide. This success has not gone unnoticed, drawing in a $10 million seed round from high-profile investors including Khosla Ventures and First Round Capital.
As Onyx looks to the future, its vision is clear: to be the foundational tool that enterprises use to build their custom internal search solutions. The company’s journey underscores a pivotal truth in the tech world—sometimes, it’s not about being first but being the one that truly understands and solves the problem.
With an open-source heart and a startup spirit, Onyx stands poised to redefine enterprise search, one data trove at a time.
