HOW WE SCALE

SINCE 2013

Since 2013, our economists have advised on complex competition matters across Europe, combining economic rigour with a practical understanding of legal proceedings.

STRONG FOUNDATIONS

Complex matters demand more than familiarity with precedent. Our grounding in economic theory and econometrics allows us to develop robust, defensible analyses, spot non-obvious angles and handle novel theories of harm or challenging datasets.

FOCUSED TEAMS

We work in lean teams, scaling as required, to provide direct access to senior economists, clear accountability, and focused analytical support. This approach avoids unnecessary delegation and ensures every matter benefits from experienced judgement.
