Héctor Madero Rivero is a seasoned Mexican financial services executive and the Chairman of the Board of Actinver, one of Mexico's leading investment advisory and private banking groups. He currently serves as an Independent Director Nominee and Executive Chairman of West Enclave Merger Corp. (NYSE: WENC), a blank check company that priced its $100 million initial public offering on April 29, 2026, with the offering closing on May 1, 2026. West Enclave Merger Corp., headquartered in Ciudad de Mexico, was formed for the purpose of effecting a merger, share exchange, asset acquisition, or similar business combination with one or more businesses. At WENC, Madero Rivero sits alongside a board that includes Co-Chairmen and Co-CEOs Emilio Mahuad Quijano and Adrian Otero Rosiles, Independent Director Alberto Fasja Cohen, and Independent Director Nominee Jean-Michel Enriquez Dahlhaus. Through Actinver Inversiones Alternativas, S.A. de C.V., an entity he controls as Chairman of Actinver, Madero Rivero indirectly acquired 180,000 WENC ordinary shares in connection with the IPO, comprising 20,000 private units purchased at $10.00 per unit (totaling $200,000) and 160,000 founder shares transferred from West Enclave Sponsor LLC for aggregate consideration of approximately $1,043.48. He disclaims beneficial ownership of these shares except to the extent of his pecuniary interest in Actinver.
Madero Rivero's career is deeply intertwined with the growth of Actinver, which he has described as having started as a family business before becoming a fully public company with more than 2,000 shareholders, none individually holding more than 10 percent. The Madero family, through its six members, retains approximately 20 percent of the company. In a 2012 interview with The Worldfolio, when he held the title of President of Actinver, he outlined the firm's dual focus on private banking for individuals seeking sophisticated investment products and an investment bank dedicated to bringing Mexican companies to public markets. He emphasized Actinver's asset management capabilities, noting that over the prior 15 years the team had consistently generated above-market returns across debt and equity instruments, and highlighted the firm's expertise in private equity investments and understanding of Mexican market idiosyncrasies for foreign investors. By February 2024, Madero Rivero had been leading the Actinver bank on an interim basis as CEO before being replaced by the institution's CFO, transitioning to his current role as Chairman of the Board. At Actinver Day 2025, he delivered a presentation highlighting the institution's 30-year history and its evolution into a pillar of Mexico's financial system.
Under Madero Rivero's leadership, Actinver has pursued a strategy of expanding access to sophisticated investment products for Mexican investors, including the launch of ETFs targeting the MILA (Mercado Integrado Latinoamericano) region in 2016. His son, Alonso Madero Rivero, served as CEO of Operadora Actinver S.A. de C.V. from 2011 to 2021 and as investment director of Actinver Corp., where he championed the tracker fund business and its potential in Mexico, noting that Mexican pension funds (Afores) could be interested in instruments combining the largest liquid companies of the Pacific Alliance. The Madero family's multi-generational involvement in Actinver reflects the firm's origins as a family enterprise that matured into a publicly traded financial institution with a fully independent board. Héctor Madero Rivero has stated that his vision for Actinver is not personal fame but to build a business that serves as a pillar in Mexico's financial system, leveraging the country's demographic potential—a nation of 125 million people with a median age of 25—to grow capital markets and financial services penetration. The board and shareholders of Actinver have also committed a percentage of annual profits to social, educational, health, and environmental cau
This record is keyed to SEC CIK 0002126430 — the identifier this person files under in their own name. Every vehicle above is a filing made under that CIK, so “the same person on two shells” is a fact about an SEC identifier rather than about a name that happens to match.
Roles are the strings the filings used, in the order they were filed. Nothing on this page ranks them, infers seniority, or offers a reason why any two of these names recur — a recurrence is a count, and the filings that produced it are linked beside every row. We also hold 2 institutional-holder rows on these vehicles, under 2 distinct name strings, and none of them is counted across vehicles: that table has no CIK column, and matching holders by name would merge firms that are not the same firm.
