Elder Research vs Thoughtworks: overview

Elder Research

Elder Research has advised on analytics since 1995 from Charlottesville, Virginia, and has around 170 staff. ManTech, owned by Carlyle, bought it in December 2025. Its readiness work rests on decades of hands-on modeling, so its view on whether your data can support a use case is grounded in practice. European regulation is outside its usual territory.

Thoughtworks

Thoughtworks has around 10,000 people and has been based in Chicago since 1993. Apax took it private in a deal announced in August 2024, and a 2026 joint venture with New York advisory firm Teneo aims to strengthen its business advice. Its own advice is strongest on software and data foundations, and its public Technology Radar shows how it judges tools before you hire it.
