At Haystack, we want to hear from practitioners from around the world who are tackling hard search & AI problems. While search continues to serve many classical retrieval use cases, it has also has become a key enabler for generative AI.
Our attendees want to hear all about this evolution, from the big picture business decisions down to the nuts and bolts of selecting an algorithm or model to realize a technical goal. Your audience will primarily consist of search professionals, product owners, product managers, AI and relevance engineers, and other developers.

Haystack is the conference for improving search relevance. If you’re like us, you work to understand the shiny new tools or dense academic papers out there that promise the moon. Then you puzzle how to apply those insights to your search problem, in your search stack. But the path isn’t always easy, and the promised gains don’t always materialize.
Haystack is the conference for organizations where search, matching, and relevance really matters to the bottom line. For search managers, developers, relevance engineers & data scientists finding ways to innovate, see past the silver bullets, and share what actually has worked well for their unique problems. Please come share and learn!
