Inès Lassalle has been recognized with a 2025 Global Recognition Award for her exceptional ability to bridge two of the world’s most complex legal systems, the United States and France, delivering cross-border legal strategy and compliance solutions that serve founders, executives, athletes, and investors operating at a global scale in Leadership, Service, Research, and Innovation.

Dual-qualified and licensed in California and France, Lassalle has built a practice that operates across the full breadth of legal rigor and business pragmatism, serving clients in sectors where regulatory complexity defines the operating environment. Her client base includes artificial intelligence, healthtech, hospitality, real estate, and venture-backed enterprises, each requiring precise and jurisdiction-specific legal counsel. Through US Expansion Partners, the firm she founded in September 2023, Lassalle leads cross-functional legal operations for foreign businesses entering or scaling in the US market, designing operational compliance frameworks and managing entity structuring across multiple jurisdictions.

Her academic foundation is as international as her practice, reflecting a deliberate pursuit of legal and financial expertise across continents. Lassalle earned her Juris Doctor from the University of Paris I: Panthéon-Sorbonne, completed business and finance studies at UCLA, and trained in mergers and acquisitions at the École de Formation Professionnelle des Barreaux de la Cour d’appel de Paris (EFB). She also holds certificates in contract law from Harvard University and in financial markets from Yale University. These credentials give her legal advice a multidimensional quality rare even among experienced cross-border practitioners.

A Practice Built on Bridging Jurisdictions

Before establishing her own practice, Lassalle worked at Gibson Dunn in Paris as a corporate lawyer and served as a corporate M&A lawyer at Thales, one of France’s largest defense and technology conglomerates, gaining direct exposure to the mechanics of large-scale cross-border transactions. She also gained international tax experience at EY. She contributed to business law work at the Clinique Juridique de Paris and Sorbonne Junior Conseil, roles that shaped her understanding of regulatory compliance across jurisdictions. These formative experiences gave her the technical foundation to serve globally mobile clients with a level of precision that few practitioners at her career stage can match.

Global Recognition Awards evaluates candidates through a rigorous process that includes screening by a panel of industry experts, followed by assessment using the Rasch model. This psychometric measurement tool creates a linear scale, allowing precise comparisons across applicants excelling in different disciplines. Lassalle scored highest across Leadership, Service, Research, and Innovation, reflecting the breadth and depth of her contributions to the legal profession. Her evaluation identified maximum marks in areas including ethical decision-making, measurable service outcomes, international collaboration, and market impact, a profile that is consistent with world-class standing.

Leadership, Service, and the Next Generation

Lassalle’s leadership extends well beyond the courtroom and the boardroom, reaching into the development of future legal professionals through her work as a judge in international legal competitions, including the AMCA and NMCC, with her upcoming participation in the Vis Moot, one of the most prestigious international commercial arbitration competitions for law students. Through these roles, she provides structured feedback on written and oral advocacy at the highest student level, contributing directly to the quality of legal education worldwide. This commitment to mentorship is a consistent thread running through her career, dating back to her early participation in the Clinique Juridique de Paris, where she supported business law work as a student practitioner.

Her service extends beyond mentoring to the direct representation of clients navigating some of the most complex legal environments in practice today, including high-profile athletes managing global venture structures and emerging innovators addressing multi-jurisdictional compliance requirements. The measurable outcomes of her work include successfully structured US market entries, operational frameworks that reduce cross-border legal risk, and client relationships in multiple industries and continents. These are not abstract contributions, but concrete results that demonstrate her capacity to operate as a true strategic partner rather than a transactional legal advisor.

Final Words

What sets Lassalle apart is not simply the number of jurisdictions she operates across, but the consistency and quality of the frameworks she constructs within them, which reflect a level of professional maturity that exceeds what her years of practice might suggest. Her ability to integrate legal, regulatory, and business strategy, particularly in high-stakes or emerging sectors, demonstrates a command of complex environments that few practitioners develop so early in their careers. The range of her clientele, from European founders and U.S.-bound startups to athletes and creatives navigating global transitions, speaks to a practice that is versatile and methodical in its execution.

Inès Lassalle’s recognition with a 2025 Global Recognition Award reflects the kind of cross-border legal leadership that the modern global economy increasingly demands, one grounded in academic excellence, practical experience, and a genuine commitment to expanding access to legal clarity across borders. Her work with US Expansion Partners, her educational credentials, her dedication to legal education, and her ability to translate complex, multi-jurisdictional challenges into actionable strategy represent a rare and instructive standard of professional excellence. Alex Sterling, a spokesperson for Global Recognition Awards, noted, “Inès Lassalle exemplifies the kind of legal professional who does not just navigate complexity, but builds the infrastructure others use to cross it, and that is precisely why she has earned this recognition.”
