What Muñoz Manzo y Ocampo does

Muñoz Manzo y Ocampo S.C. (MM&O) is a privately held Mexican boutique advisory firm that delivers fiscal, legal, and wealth-management (patrimonial) consulting services from a single headquarters in Mexico City's Corporativo Espacio Santa Fe. The firm operates with approximately 17-18 professionals organized into founding partners (Alejo Muñoz Manzo and Eduardo Ocampo Gayón), equity partners, associates, and managers, structured around three integrated service lines: Servicios Fiscales (tax consulting, financial-sector transactions, stock-exchange emissions, investment and infrastructure projects, corporate restructurings, and proceedings before tax authorities), Servicios Legales (contentious and constitutional litigation in fiscal and administrative matters, plus alternative dispute resolution such as conclusivo agreements), and MM&O Patrimonial (estate planning, family tax consulting, succession planning in Mexico and abroad, TRUST BOOK service, and cross-border wealth structuring).

The firm serves large Mexican corporations, foreign companies with Mexican operations, public and private investment funds, and high-net-worth families and family offices, with no proprietary technology platform or software product — services are delivered directly by partners and staff on a project, retainer, or hourly basis. The underlying "platform" is the partner-led advisory model itself, supplemented by a content-marketing program (the Flash Fiscal blog series covering Paquete Económico and Reforma Fiscal developments) and a US tax alliance with Kbibb LLC that extends MM&O's effective geographic reach for cross-border engagements. Revenue mechanics are entirely fee-based professional services, with engagement-level pricing disclosed only on a case-by-case basis and no standardized public pricing tiers.

The go-to-market is sales-led and relationship-driven, relying on professional referrals, the firm's blog and newsletter, and a LinkedIn presence rather than intermediary channels or marketplaces. Ownership remains with the founding and equity partners, with no disclosed institutional investors, parent company, funding history, acquisitions, or public listing.
