It operates from Greenwich, Connecticut. The firm invests in media, internet and consumer sectors. It deploys capital through direct investments and allocations to outside managers, covering venture stages from seed through late stage as well as public equities and hedge strategies. Allocations occur across North America. The office also supports philanthropic initiatives focused on education. The team includes Drew Marcus as Managing Partner, Catherine Jordi Marcus as Managing Director, and advisors Mark Greenberg and Larry Marcus. The firm participates in organizations such as the Greenwich Country Day School endowment committee and the Boys and Girls Club of Greenwich. No operational events from the last 24 months appear in available records.
