What GAMMA Investing does

GAMMA Investing is a U.S.-based registered investment adviser that operates a Custom Index SMA (Separately Managed Account) platform, often referred to as a direct-indexing marketplace, serving wealth advisors and institutional investors. The firm provides separately managed accounts that hold custom portfolios of securities tracking indices while permitting personalization against client goals, social values, and tax management objectives. Its platform spans equities, fixed income, and options strategies, with explicit capabilities for custom index development, mass customization, and systematic tax-loss harvesting throughout the year. The company positions itself as a 'centralized marketplace' connecting RIAs, family offices, private client groups, banks, endowments, foundations, retirement plans, insurance companies, sovereign wealth funds, and non-U.S. institutions to institutional-caliber personalized index solutions.

Underlying technology consists of a proprietary Custom Index SMA stack enabling direct indexing with structural advantages over ETFs, supported by a custom execution model intended to generate lower costs and tax efficiency for clients. Distribution is sales-led, targeting financial intermediaries and institutional investors through direct relationships, an advisor/client portal, and educational content marketing. The firm is an independent, woman-owned LLC headquartered in Foster City, California, with additional offices in San Francisco and San Mateo. Revenue is generated through AUM-based management fees on Custom Index SMA accounts; AUM reached $1.23 billion as of December 31, 2024, a 264% increase since year-end 2023, following a founding year of 2020 and a team of 11–50 employees.
