Background

Jack A. Goldstein is a Partner at DC Capital Partners, where he is responsible for sourcing, evaluating, and executing new investments and supporting existing portfolio companies operationally. DC Capital’s current bio says he joined the firm in 2020 and has since been involved in more than 15 platform investments and add-on acquisitions, numerous financings, and the sales of Pond Holdings, LLC and PBK Architects, Inc.

Goldstein currently serves on the boards of Valkyrie Enterprises, LLC and PK Companies, LLC. His recent public deal commentary centers on platform-building in regulated, mission-critical markets, including Valkyrie’s 2025 acquisition of Optical Sciences Corporation and PK Companies’ 2026 acquisition of Pro-Surve Technical Services.

Before DC Capital, Goldstein worked in investment banking at Jefferies LLC. DC Capital states that he advised on more than 20 M&A and capital-markets transactions totaling approximately $15 billion across the aerospace, defense, government and engineering services sectors. While at Jefferies, he worked with DC Capital on transactions involving Michael Baker International, Acuity International, formerly Caliburn International, and other M&A and debt-financing efforts.

Goldstein earned a B.B.A., cum laude, from the College of William & Mary, majoring in Finance with double minors in Accounting and Economics.

Investment Thesis & Focus

  • DC Capital is not an angel or seed investor based on current primary sources; it is a private equity firm making control investments in middle-market businesses.
  • The firm’s core market is U.S.-based Government and Engineering companies, especially businesses with differentiated services or technology, mission-critical use cases, and durable customer demand.
  • DC Capital says it creates value by taking “an active role with management in developing strategy” while supporting execution.
  • The firm’s stated three-pillar process is “Domain Expertise, Market Focus, and Strategic Process.”
  • DC Capital emphasizes fragmented markets with long-term contracts and predictable cash flows; its approach page says Government and Engineering markets include thousands of lower-middle-market companies and more than $700 billion in annual spending.
  • The 2017 Fund II close materials cited a target of $25 million to $75 million of aggregate equity per platform, with co-investment capacity for larger deals.
  • Goldstein’s public deal comments suggest interest in businesses where capital can fund geographic expansion, new capabilities, technology investment, production capacity, and add-on acquisitions.
