Analysis Group Forms Partnership with Distinguished French Consultancy Ricol Lasteyrie, Strengthening the Reach of Both Firms
Analysis Group, one of the world’s largest economic consulting firms, has joined forces with Ricol Lasteyrie, a long-established Paris-based consultancy known for its financial, extra-financial, and governance expertise in France and in Europe. The partnership, announced by the firms today, brings together two highly regarded businesses to offer clients in Europe and worldwide an integrated approach that combines the deep resources of both firms.
As a firm founded in 1986 and recognized for its rigor and independence, Ricol Lasteyrie has long supported senior executives, investors, and institutions on strategic financial matters and complex disputes. Its heritage and proven reliability position the firm as a trusted advisor to leaders navigating demanding market environments.
Together, the teams will provide expanded expertise in areas such as competition, commercial disputes, arbitration, accounting, valuation, and compliance with environmental, social, and governance (ESG) standards. Each will benefit from the integration: Analysis Group will extend its presence in Europe, with the ability to offer clients insight into market-specific dynamics to complement our well-known expertise in economics and antitrust, while Ricol Lasteyrie will add depth to its record of supporting a wide variety of European corporations, investors, and institutions with their most complex strategic, financial, and litigation matters.
“Analysis Group has handled numerous matters where deep financial expertise would have perfectly complemented our economic analyses,” said Managing Principal Antoine Chapsal, head of Analysis Group’s European offices. “The recognized financial and strategic capabilities of the Ricol Lasteyrie team, combined with our experience in competition and litigation in both Europe and North America, will allow us to serve our clients with even greater precision and breadth.”
“My view of the market today led me to call on economists to provide complementary insight and meet my clients’ new requirements,” said René Ricol, chairman and founding partner of Ricol Lasteyrie. “After a year of collaboration on complex matters, bringing our firms together became the obvious next step.”
The combined European team – based in Paris, London, and Brussels – will now include more than 100 professionals. They will continue to collaborate closely with Analysis Group’s North American offices, strengthening the firm’s transatlantic capabilities and offering clients comprehensive, data-driven perspectives on evolving market dynamics.
“Our integration with Ricol Lasteyrie underscores our long-term investment in people and the power of global collaboration,” said Pierre Cremieux, CEO of Analysis Group. “Together, we will continue to cultivate top talent and share expertise across borders to solve our clients’ most complex challenges.”
“This partnership reflects our shared commitment to analytical rigor, independence, and intellectual curiosity,” added Dr. Chapsal. “By uniting our strengths, we can provide the highest-quality support to companies navigating today’s evolving economic, regulatory, and geopolitical environment.”
