Galliott Capital Advisors

Antoine Souma established Galliott Capital Advisors after more than twenty years advising clients at larger institutions. The firm operates from Beverly Hills and serves multigenerational families whose primary residences are often abroad. It positions itself as an independent provider of family-office-style services without corporate ownership constraints. Galliott allocates across public markets, private equity, real estate, hedge funds, secondaries, direct co-investments, and digital assets. Confirmed holdings include SpaceX, Epic Games, Gemini, DataRobot, Toast, and Olivela. The firm covers pre-IPO, seed, Series A, and Series B stages. Geographic reach spans North America, Europe, the Middle East, Asia, Africa, and South America. The team includes Robert Mourad, who joined as Chief Portfolio Strategist in April 2022 from UBS Financial Services. Galliott maintains one office at 9401 Wilshire Boulevard. It collaborates on educational initiatives through the Rafik Hariri University Board of International Advisors. Antoine Souma serves as Vice Chairman of that board. Independence allows Galliott to maintain open architecture across custodians and external managers while acting in a fiduciary capacity. The structure emphasizes direct relationships with clients rather than product distribution, enabling customized mandates that combine traditional and alternative investments.
