Corporación Inmex
Corporación Inmex was established to steward the wealth generated by the Soriana retail empire, where the Martín family cemented its position through the landmark Soriana-Sorimex merger. Founder Alberto Martín-Soberón later expanded the family's interests into financial services, co-founding Grupo Inmex and chairing Investar Financial, a US-chartered community bank headquartered in Irving, Texas. The office's investment mandate draws directly from this operating background — blending commercial real estate ownership, a regulated banking subsidiary, and a direct venture portfolio. The firm's venture deployment targets Seed, Series A, and Series B opportunities, with confirmed sector focuses including FinTech, PropTech, Industrial Tech, and Mobility & Transportation. Geographic coverage spans Mexico, the broader Caribbean, and South America, reflecting deep regional ties. Real estate assets include Compañía Inmobiliaria Mirador, a commercial property portfolio anchored in Gómez Palacio, Durango, and a mixed-use portfolio extending into the United States. The family office participates via direct co-investments and SPVs rather than through blind-pool fund commitments. Martín-Soberón's professional network provides a sourcing edge: he sits on the board of the Asociación de Empresarios Mexicanos, an exclusive club of Mexican business owners, and serves on the Stanford University Parents Advisory Board — the same board where Steuart Walton of the Walmart family has been active. The Investar Financial subsidiary, a Texas-chartered commercial bank, offers a permanent capital base unusual among single-family offices, potentially backstopping deal flow and credit needs for portfolio companies. While total AUM remains undisclosed, the combination of an operating bank, direct real estate, and a multi-geography venture book suggests a deployment capacity in the hundreds of millions. Corporación Inmex's architecture departs from the standard family office template by maintaining a wholly-owned, FDIC-regulated financial institution on US soil. That structure provides permanent capital, lending capabilities, and a regulatory footprint that most Latin American family offices lack — effectively giving the firm the posture of a holding company with a venture arm, rather than a pure allocator.

Frequently asked questions
Who runs investment decisions at Corporación Inmex?
Founder Alberto Martín-Soberón oversees investment strategy and capital allocation. He chairs Investar Financial Corporation, the family's Texas-chartered bank, and represents the office in deal sourcing through the Asociación de Empresarios Mexicanos. The office has not publicly named additional investment professionals or an external CIO.
How is Corporación Inmex related to Soriana?
The Martín family's wealth originates from the Soriana supermarket chain, one of Mexico's largest retailers. The family's position was solidified through the Soriana-Sorimex merger. Alberto Martín-Soberón later diversified into banking and venture, creating Corporación Inmex as the family's principal investment vehicle separate from the retail operating company.
Does Corporación Inmex operate a bank?
Yes. The family controls Investar Financial Corporation, a US-chartered commercial bank headquartered in Irving, Texas. This FDIC-regulated subsidiary distinguishes Corporación Inmex from most single-family offices by providing a permanent capital base, lending capacity, and a US financial regulatory footprint.
What investment stages does Corporación Inmex target?
The firm writes checks from Seed through Series B, with a preference for direct co-investments and special-purpose vehicles rather than fund commitments. Sector focuses include FinTech, PropTech, Industrial Tech, Mobility & Transportation, and SpaceTech, among others, across North America, South America, and the Caribbean.
Does Corporación Inmex have real estate holdings?
Yes. The office owns Compañía Inmobiliaria Mirador, a commercial property portfolio in Gómez Palacio, Durango, and holds a mixed-use real estate portfolio spanning Mexico and the United States. These holdings operate alongside the venture and banking divisions.
What is Corporación Inmex's known posture on co-investments?
The firm participates in direct co-investments and SPVs across its venture portfolio. Its geographic focus on Mexico, the Caribbean, and South America, combined with Alberto Martín-Soberón's AEM and Stanford board networks, suggests a relationship-driven co-investment model that leverages personal connections rather than blind-pool fund structures.
Is Corporación Inmex a single-family office or a holding company?
In practice, it is both. While legally structured as a single-family office, the firm's ownership of Investar Financial Corporation — an operating, FDIC-regulated bank — and direct real estate subsidiaries gives it the characteristics of a family holding company with a venture investment arm, a model more common among European industrial families than Latin American family offices.
