Opening its doors in March 2024, boutique firm Assembla is equipped to provide M&A, joint venture and general corporate law advice to private equity funds and corporations in the consumer goods, manufacturing, energy and financial services sectors, among others. The ‘highly-specialised and professional’ team is led by ’excellent lawyer’ Andrés Nieto, who divides his time between Mérida and Mexico City and specialises in M&A, private equity and financing transactions, as well as energy and mining law. Further partner-level input is provided by Alejandra Gutiérrez, who draws on experience advising Mexican and foreign companies on their operations in Mexico, in addition to handling cross-border M&A transactions with real estate components, particularly in the hospitality and tourism sectors. We are saddened to report that co-founding partner Alfonso Razú passed away in September 2025.
