OpenSource Connections Search and AI Events
We run Haystack – the premier search and AI event – twice a year in the US and Europe, along with smaller Haystack events on both sides of the Atlantic throughout the year. We also host the London Lucene/Solr Meetup and the Haystack LIVE! Meetup (which includes regular online talks on search & AI). Many of our team members are regular speakers at other industry events including ApacheCon, Berlin Buzzwords, MICES (Mix Camp for E-commerce), OpenSearch Con, Search Solutions, Taxonomy Bootcamp & Enterprise Search Summit. Come and meet our team!
