## About

Etrnty was established as a multi-family office in Sao Paulo by Geraldo Lamounier. The firm supplies investment management and advisory services to Brazilian families that require both local and cross-border structures. Its client base spans first-generation wealth holders, recent accumulators and next-generation principals. Allocation spans early-stage direct co-investments, private equity, private credit, real estate, hedge funds, insurance-linked securities and carbon assets. The firm also maintains exposure to collectibles and philanthropic vehicles. Geographic reach covers South America, North America, Europe, Asia, the Middle East and Africa. No named portfolio holdings appear in public materials. Team size and headcount remain undisclosed. Etrnty Capital Gestora de Recursos operates from the same Sao Paulo address. XP Inc. took a 20 percent stake in Etrnty Holding S.A. in January 2022. The firm belongs to ANBIMA. Etrnty structures its mandate around a single-family-office-style independence despite serving multiple clients. This separation is reinforced by the minority stake held by XP Inc., which supplies distribution reach without altering day-to-day investment authority.
