Jo Kristian Bergum is currently the CEO of Hornet, a company building advanced retrieval engines designed for AI agents. Based in Trondheim, Norway, Bergum is recognized for his expertise in search technology, previously contributing notable work to projects like Vespa and writing on topics such as semantic search, ranking models, and large-scale vector databases.

In 2012, Doug got bit by the search bug and he's still trying to keep up. From full-text search, to Learning to Rank models, to search agents that generate their own code, he knows the endless landscape first hand. Yet Doug wants to deeply understand the what / how / why, and help teams use these technologies practically, distinguishing hype from reality.

He’s led search at Reddit, Shopify, and Wikipedia, authored Relevant Search and AI Powered Search, and advised 100+ organizations over the years - all in pursuit of the same question: how does search actually work?
