Main Street Advisors

Main Street Advisors (operating as MSA Advisors, LLC) is a private equity and investment advisory firm founded in 1997 by CEO Paul Wachter, alongside principals Christopher Fillo and Alexandre Cohen, headquartered in Santa Monica, California. As a registered investment adviser, MSA offers strategic financial advisory, wealth management, and merchant banking services, building diversified portfolios across equities, fixed income, hedge funds, private equity, and real estate for high-net-worth individuals, trusts, and foundations. The firm focuses on media, music, entertainment, and professional sports, partnering with high-profile figures and brands. Notable investments and partnerships include Beats, Fanatics, Tonal, Sweetgreen, Dave's Hot Chicken, GOAT, Calm, Beyond Meat, Rapyd, and stakes tied to LeBron James and the Boston Red Sox/Liverpool FC ownership groups. MSA's investment approach centers on long-term strategic partnership rather than pure capital deployment, often supporting clients' personal brand-building and business ventures alongside traditional portfolio construction. Its criteria favor consumer, sports, and entertainment-adjacent businesses with strong brand potential; check sizes are not publicly disclosed, and the firm operates as a boutique, principal-owned advisory rather than a traditional blind-pool fund.
