For 28 years, The Legal 500 has been analysing the capabilities of law firms across the world. The GC Powerlist is the latest publication from The Legal 500, turning its attention to the in-house function, and recognising those corporate counsel who are driving the legal business forward. The latest edition is the GC Powerlist: US Teams, which identifies an array of the most influential and innovative in-house teams working in the United States.
Our commitment to the in-house market is expanding, not only through the publication of the GC Powerlist Series, but also with our wide range of events, seminars, roundtables and legal updates. We have also launched GC Magazine, a quarterly title (free of charge to in-house counsel) that looks at the business of being an in-house lawyer, from a strategic, commercial and theoretical standpoint. We understand that the biggest issues facing in-house counsel today are, in fact, rarely legal issues. Our editor-in-chief, Catherine McGregor is now based in the United States and is travelling the length and breadth of the country to meet, interview, analyse and finally share the very best that the in-house market has to offer.
If you have feedback on the GC Powerlist: United States Teams, or wish to nominate other in-house individuals (either in US or global), please do get in touch at [email protected].
We hope that this listing will stimulate debate around the role of the in-house lawyer and help corporate counsel with possible improvements and efficiencies in running their departments.

Known as the ‘Pacto por México’, the package of structural reforms adopted by the current administration upon its election in 2012 has already helped bring more investment to Mexico. While it remains necessary to fully employ the national budget so as to create new jobs and further grow employment, major structural measures have already been legislated by Enrique Peña Nieto’s government and these will effect competition, energy, finance, labor, infrastructure, telecommunications, amparo law (a constitutional appeal), private data protection, public private partnerships, anticorruption, education, transparency and tax matters. Significantly, implementation has already begun. These structural reforms have been rolled out at a time when Mexico –like other jurisdictions- is enduring a notable reduction in oil prices, but this has had only a limited impact on global oil companies’ interest in Mexico’s offshore hydrocarbons potential, since the major oil-and-gas players are aware that such projects generally require years to develop and can provide returns for decades. According to the OECD, full implementation of the reform package in the short term is crucial to the country’s reaping the benefits that will accrue from a strong and sustainable recovery, and could add as much as one percentage point to the annual per capita growth trend of Mexico’s GDP.
Each of the reforms noted above, address the key issues and challenges in their respective sectors. The Mexican economy currently ranks as the world’s 11th largest and the country is also the fourth largest exporter of automobiles and manufactures the vast majority of flat screen televisions sold in the United States. In fact, Mexico exports more manufactured products than the rest of Latin America combined. Many US law firms have implemented or considered the hire of individuals or groups with significant business activity, opening offices in Mexico from where they can better serve their clients’ requirements or deliver services at a lower price. This scenario presents a unique opportunity not only to grow the services local firms provide to existing clients but also to compete for and acquire new clients.
On the other hand, the role of the in-house lawyer is crucially important since they manage the legal risks associated with the business and legal issues involved in all decisions by management. Moreover, in-house lawyers have to respond to increasing pressure on legal costs, responding proactively with initiatives for cost reduction and identifying appropriate benchmarks to permit the measuring of efficiency. When making the transition from private practice to an in-house role, most lawyers move from a specialist background to a more generalist role with responsibility for areas in which they have markedly less experience. This potentially opens huge areas of opportunity for them, since in-house lawyers who demonstrate the ability to make commercial decisions find it easy to connect with the (internal) business teams and will further a company’s ability to make sound strategic choices based on analysis that combines both legal and commercial factors.
In this regard, relationships between in-house lawyers and external lawyers are becoming increasingly important. The successful appointment of preferred legal advisors and the development of a close working relationship with a law firm can be a significant opportunity for in-house legal teams and can help save both time and money.

The 2025 edition of the GC Powerlist Colombia, held at the elegant Casa Medina in Bogotá, brought together some of the most influential general counsel and in-house legal leaders from across the country and region. The event highlighted how Colombian legal departments are evolving to meet the demands of an increasingly complex, tech-driven, and sustainability-conscious business environment. Key themes throughout the day included the strategic adoption of AI and legal tech, lean but agile team structures, shifting approaches to external counsel, and a strong commitment to ESG and inclusive leadership.
One of the most prominent discussion points was the integration of legal technology, particularly AI and large language models, into in-house legal work. Across companies like Uber, Unilever, Takeda, and GFT, there is strong momentum around the use of AI tools for contract lifecycle management—ranging from clause extraction and risk flagging to version control and automated drafting. However, rather than viewing AI as a replacement for legal professionals, most GCs described these technologies as strategic enablers that allow their teams to focus on higher-impact work. Laura Jaramillo Franco of Bayer provided one of the most detailed insights into how her team has deliberately structured their AI use. She emphasised that the value lies not in using AI for its own sake, but in tailoring each tool to specific use cases that align with legal risk standards and data protection policies. Tools such as Harvey, myGenAssist, Claude, Notebook, ChatGPT, Gemini, and Gamma are all part of Bayer’s ecosystem—each selected and implemented with clear purpose and governance.
Legal design was another emerging theme, with institutions like Scotiabank and Unilever investing in simplifying legal documents to make them more accessible to non-legal stakeholders. This is especially relevant in consumer-facing sectors where clear communication builds trust and mitigates risk. There is also growing interest in predictive analytics for litigation and compliance risk mapping, as legal departments seek more proactive ways to support business decisions.
Despite the growing influence of technology, staffing models remain lean. Most legal departments consist of teams ranging from three to nine professionals. However, size is no longer the defining factor of effectiveness. Instead, agility, business-embeddedness, and cross-functional collaboration are key. General counsel from companies such as Scotiabank, Cargill highlighted the increasing involvement of legal leaders in crisis management and business strategy, often working side by side with finance and communications teams. Upskilling, especially in technology and leadership, is an area of active investment, with Uber, for instance, noting formal programs aimed at equipping in-house lawyers for this evolving role.
The event also revealed a shift in the use of external counsel. In-house teams are now more confident in handling complex matters internally, including regulatory strategy, litigation, and M&A. Companies such as SierraCol and Bancolombia highlighted that while law firms remain essential, engagements are becoming more selective and strategic. The focus has moved from transactional work to long-term partnerships that add specialized value or support cross-border challenges.
Sustainability and ESG responsibilities continue to expand within legal departments. Legal leaders are increasingly central to ensuring compliance with ESG frameworks, advising on disclosures, and shaping product strategies aligned with social impact. Viviana Prada Rey of Grupo Cibest shared how her legal team plays a key role in advancing the company’s mission to contribute to the UN Sustainable Development Goals. From advising on sustainable finance initiatives to monitoring ESG-related regulatory developments in both Colombia and the United States, the legal function has become instrumental in driving long-term impact.
Another area of strong focus was crisis resilience. Legal teams are leading scenario planning and designing compliance playbooks, ensuring they are prepared for unexpected events. Leadership and inclusion also featured prominently. Companies are integrating diversity, equity, and inclusion (DEI) into their legal team strategies. Juliana Hoyos Flórez, General Counsel of SierraCol, discussed the company’s ALMA program (Academia de Liderazgo para Mujeres de Alto Impacto), which has empowered over 180 women across the company and community with leadership skills and is expected to reach 300 by 2026.
In conclusion, the GC Powerlist Colombia 2025 was a testament to the transformation of the legal profession in the region. Far from being reactive support functions, today’s legal departments are strategic, tech-savvy, socially conscious, and embedded at the heart of business decision-making. As demonstrated once again, Colombia’s in-house legal leaders are not just keeping pace with global trends—they are helping define them.
