Epacria Capital Partners

Epacria Capital Partners was established in 2021 by Thomas M. Clay to oversee the fortune built by his father, Landon T. Clay, who chaired Eaton Vance until his death. Lavinia D. Clay joined as co-founder. The office operates from Boulder with a mandate centered on after-tax returns. The firm allocates across public equities, private equity, natural resources and distressed situations. It executes through direct co-investments and SPVs rather than broad fund commitments. Confirmed exposures include positions in healthcare services and industrial technology companies. Activity spans North America and South America. Buyout and growth stages receive primary attention. Team size remains undisclosed. Thomas M. Clay also chairs the Clay Mathematics Institute, an adjacent vehicle created by the family. No additional offices appear in records. No operational events from the past 24 months have been verified. The structure ties investment decisions directly to family principals without external limited partners. This setup allows extended holding periods and avoids typical fund lifecycle pressures.
