## About

Michael Danziger established Danziger Family Investments in 2004 following the sale of multiple data and trade-media companies he founded or led. Prior roles include nine years running Thomson Financial Services Database Group and founding IDD Information Services and Rand Communications. The firm operates from Marlboro, New Jersey. DFI acquires and operates small or middle-market companies with a focus on B2B information, services and software. Investment types include direct co-investments, private equity, private credit, hedge funds and real estate. Confirmed positions trace to earlier ventures such as Buyers Laboratory, acquired by SFW Capital Partners in 2012. The firm maintains exposure across North America, Europe, Asia, the Middle East and South America. The team consists of Michael Danziger as Senior Partner. Additional relationships include spouse Rhoda Danziger and business partner Mark Lerch, former COO of Buyers Laboratory. Philanthropic vehicles include the Children's Scholarship Fund Philadelphia and Penn Medicine Abramson Cancer Center. No operational events from the past 24 months appear in public records. DFI maintains a control-oriented mandate that pairs capital with direct operating involvement drawn from Danziger's publishing and services background.
