Built for Technical Disputes

EVO is a technology expert witness consultancy. For over three decades we've helped courts, counsel and clients make sense of disputes where technology sits at the heart of the evidence, from failed software and telecoms patents to digital forensics, crypto and AI. Behind us stands a bench of court-tested specialists across every major technical discipline, so whatever the matter, the right expertise is already in place.

Genuinely Independent

Every expert we field reports objectively, sets out the technical facts as they stand, and defends that evidence under scrutiny. They answer to the court, never to the party instructing them, and that independence is what makes our testimony credible.

Depth Across Every Sector

A standing bench spans software, telecoms, forensics, cyber, crypto, AI, gaming and automotive, and we source and vet niche specialists at pace. When a matter calls for something rare, we find the expert the question needs, never simply the nearest available.

Trusted Across Jurisdictions

Our experts have supported litigation, arbitration, regulatory investigations and public inquiries across the UK, the US, Europe, the Middle East and beyond, bringing the same rigour, clarity and quiet independence to high-stakes proceedings wherever in the world they are heard.
