Our product encompasses leading-edge AI technology, an innovative legal ontology and one of the world’s largest legal intelligence data sets.

Working with Product Owners and legal language experts, we identify complex areas of interpretation required for different types and formats of contracts, initiate research projects with specific goals, then transition these into the Fathom product alongside our Engineering teams.
