Our team

Seasoned judgement, amplified by machines we built ourselves.

Our consultants bring decades at the intersection of law, strategy, and technology. Four proprietary AI agents work alongside them — so human attention goes to strategy, listening, and client understanding.

AI-native by design

Four agents on every engagement.

They do not replace judgement — they clear the ground for it. Each is built on our own methodologies and knowledge base.

  • Legal Analyst

    Our precision-driven analyst
    Transforms hours of interviews into clear, actionable information structured according to our proprietary methodologies. It captures nuance, context, and priorities — allowing our consultants to focus on strategy, listening, and client understanding rather than note-taking.

  • Legal Benchmark

    Our instant market compass
    Performs in-depth benchmarks of the legal market in minutes — comparing organizations, models, and best practices across industries and geographies. It provides a solid factual base for decision-making and strategic positioning.

  • Legal Solution

    Our innovation partner
    Leverages our knowledge database of proven legal transformation initiatives to suggest relevant, ready-to-use recommendations. It doesn't replace creativity — it fuels it, helping us challenge and deliver smarter, more effective solutions.

  • Legal Research

    Our link to the frontier
    Continuously scans academic and technological research in the legal AI field — identifying trends, breakthroughs, and practical applications before they hit the mainstream. It ensures our methodologies and technology are backed by the latest thinking.
