Background

A. Jabbar Abdi is the Managing Partner and Co-Founder of Sidereal Capital Group, a boutique private equity firm he established in 2012 in Summit, New Jersey. Sidereal focuses exclusively on lower middle-market companies operating within well-defined niches in the specialty manufacturing and industrial services sectors. The firm provides growth equity and acquisition capital to closely-held, family-owned, and founder-run businesses, often serving as the first institutional investor. Under Abdi's leadership, the Sidereal team has collectively invested over $500 million in equity capital across 20 platform companies.

Prior to founding Sidereal, Abdi built a deep career in private equity, investment banking, and management consulting. He served as a Managing Director at Cordova, Smart, & Williams, LLC (CSW), a middle-market private equity firm where he was a key member of the investment team. Before CSW, he held multiple positions at GE Capital, including Vice President in the Merchant Banking Unit, where he was responsible for originating and underwriting debt and equity financings for leveraged buyouts in the middle market, as well as roles in GE Capital's Private Equity Unit (GE Equity). Earlier in his career, he was a management consultant at First Manhattan Consulting Group, focused on strategy development and implementation in the financial services sector, and began his career at Furman Selz, a New York-based investment bank, where he worked on mergers and acquisitions, public equity offerings, and private placements.

Abdi holds an A.B. from Harvard College and an M.B.A. from the Wharton School of Business at the University of Pennsylvania. He is active in the community, serving on the Board of Trustees for MEND NJ, an organization that strengthens and supports an interfaith network of 20 member food pantries located throughout Essex County, New Jersey. He is also a speaker and participant in industry events such as the ACG (Association for Corporate Growth) and Smart Business Dealmakers conferences.

  • Cash flow profile: Targeting businesses generating $3 million to $10 million in operating cash flow
  • Flexible transaction structures: Supporting a variety of deal types including recapitalizations and succession planning, management buyouts, industry consolidations, and corporate divestitures
  • Operational value creation: Leveraging deep experience in manufacturing and industrial services to drive growth and operational improvement in portfolio companies
