MidCoast Capital

Managing Principals Michael Cuneo and Stephen Harris direct investment decisions. They are supported by Principals James M. Buck III and J. B. Doherty, who also manage legacy TDH venture capital portfolios. The firm has operated with this four-person partnership structure since its founding.

MidCoast's proprietary sourcing channel flows from the TDH venture capital relationship. Principals Buck and Doherty split responsibilities between MidCoast assignments and TDH fund management, creating a direct line into legacy venture portfolios. This partnership overlap provides visibility into LP interests before they reach broad secondary-market processes.

MidCoast operates exclusively as a secondary buyer — it purchases LP interests in private equity and venture capital funds and direct stakes in private companies. The firm does not make primary fund commitments. It targets middle-market buyout, recapitalization, and growth-stage secondary positions.

Based on the principals' historical portfolio, the firm has invested across business services, communications, consumer products, financial services, electronics, information technology, and medical products. MidCoast targets secondary interests across these verticals rather than imposing a narrow sector mandate.

Principals James M. Buck III and J. B. Doherty are longtime partners of Managing Principal Stephen Harris in the TDH venture capital activities. They divide their time between MidCoast Capital assignments and the continued management of TDH funds. This dual-platform arrangement gives MidCoast structural access to TDH portfolio LP interests.
