Democratizing machine learning for your search team  ↓


Pioneers in machine learning

We built Elasticsearch Learning to Rank, which powers search at Yelp, Wikipedia, Snag, and others.

Since deploying learning to rank, we’ve seen a net 32% increase in conversion metrics across our historically lowest performing use-cases. — Jason Kowalewski, Sr Director of Engineering at Snag
Learning to rank can’t stay hidden away in obscure academic journals or multi-million dollar products. We’re making this stuff accessible to all search teams: opening up the black box for everyone to use”. — Doug Turnbull - OpenSource Connections CTO
