Its ontology compiler tracks requirements, dependencies and policy constraints so organizations can modernize complex software while preserving how the system is meant to work.

ParticipantGrubel
Grubel is an AI research lab developing matter-specific AI for law firms and legal teams. For each case, its system curates task-relevant data, adapts models and agents to that matter at inference time, and evaluates their work against legal-task requirements, aiming to handle complex legal work with stronger case context and confidentiality than a general-purpose assistant.
