Portfolio companies are held across these distinct fund families.

There is no mention of fund-of-fund commitments to external managers. The investment approach is built around control equity and active operational involvement.

Known positions span billing and customer-management software (National Water and Power), collaborative design tools for manufacturing (Fullscope), industrial products (EcoDuro pallets), cable broadband infrastructure (Aegis Broadband), and consumer-packaged-goods workflow software (Design2Launch). The firm focuses on information-technology and services companies that operate in fragmented, legacy-heavy markets.
