About Proteus

Experienced eDiscovery Advocates

Practicing litigators. Proactive solutions. Transparent pricing.

What makes Proteus different.

Our founders are practicing litigators with deep roots in AmLaw 100 firms. We know how foundational eDiscovery is to your case, and we have a unique understanding of all the case management pressures and challenges you face.
We embrace messy, complex cases that don't fit neatly into pre-packaged workflows because our department leaders and project managers are attorneys and technologists who average 17 years of experience in law firm and consulting roles.

Financial independence and consistent growth means there is no temptation to "over-engineer" a solution, and our pricing structure is dramatically simplified compared to industry peers.
Clients trust us because we provide sophisticated solutions and candid communications with simple, transparent pricing. We stand ready to help you, too. Together, we can do great work.
