High-stakes case matter. Industry-leading clients.
A trusted partner for turbulent times.

What makes Proteus different.

Our founders and directors are practicing litigators, so we know what it means to rely on a high quality eDiscovery work product.

Financial independence, no debt, and consistent growth means there is no temptation to "over-engineer" a solution, and our pricing structure is dramatically simplified compared to industry peers.

Finally, our project managers have varied backgrounds that cut across business, IT, and legal departments in multiple industries. This informs our platform-agnostic approach so we can meet you where you are and apply proven processes with appropriate adjustments for your unique project.
