CrossGrain Family Investments

CrossGrain Family Investments was founded in 2019 by William (Biff) Pusey Jr. and Jeffrey Mussatt. The firm operates from Henrico, Virginia, as a multi-family office providing co-investment access and limited advisory services. The platform centers on private-market deployment across private equity, real estate, private credit, and digital assets. It executes through direct co-investments, SPVs, fund-of-funds commitments, and secondaries. Activity remains concentrated in North America. The firm states it does not raise external capital or act as a paid placement agent. CrossGrain maintains a small team and one primary office. It supports the Paul H. Pusey Foundation through philanthropic channels. No operational events from the past 24 months appear in available records. The firm’s structure ties investment decisions directly to the principals’ personal capital commitments, creating a closed network for co-investors rather than an open product platform.
