Castellan Group

What Castellan Group does

Castellan Group, LLC is an independent SEC-registered investment advisor (RIA) and multi-family office founded in 2018 and headquartered in Louisville, Kentucky, with a regional office in Jupiter, Florida. The firm is wholly owned by a perpetual charitable trust — a structurally unusual arrangement under which most profits are donated to charity while the firm operates with conventional professional standards. Castellan serves ultra-high-net-worth (UHNW) multi-generational families and entrepreneurs, providing a consolidated suite of investment management (public equities and quantitative strategies), private investments and private equity (deal sourcing, due diligence, M&A support, portfolio oversight), venture capital (with a dedicated Aging Innovation Fund targeting digital health), and family office services including estate planning, tax strategy, philanthropy coordination, and reporting and risk management. The firm organizes its investment approach around a three-portfolio framework (Safety, Market, Aspirational) and supports clients with proprietary reporting and data visualization tools, including integration with Masttro for consolidated asset visibility.

The firm's revenue is generated through recurring investment advisory fees on assets under management, private equity and venture capital fund management fees and carried interest, and bespoke family office professional service fees. The firm has built a portfolio of more than 11 portfolio companies spanning healthcare technology (HealthLink Dimensions, Medxoom, Readyworks, HealthCorum), fintech (HALO Investing, Merit), sustainability (SustainaBase), advanced manufacturing (WEAV3D), consumer brands (Green District, CircleUp), real estate (PTM Partners), and visual AI (Levatas). Public-equity AUM is evidenced by quarterly 13F filings showing meaningful new positions in large-cap names. Beyond the advisory business, Castellan distributes a publicly available exchange-traded fund (Castellan ETF) through Quasar Distributors and recruits from a pipeline of top-tier university interns, suggesting a measured push to broaden product surface and talent access over time.
