• Arnold is not currently verified as an active angel or seed investor. The verifiable investment profile is her historical private-equity work at The Sterling Group and Madison Dearborn Partners.
• At Sterling, the relevant thesis was control-oriented middle-market private equity in industrial/basic-industry businesses. Sterling describes its criteria as “Corporate carve-outs, family / entrepreneur owned businesses or sponsor owned businesses.”
• Sterling’s sector focus was basic industries: manufacturing, distribution, industrial services, and business services.
• Sterling’s historical check-size range was materially larger than seed/angel investing: $50 million to $350 million equity investments and $100 million to $1 billion transaction sizes.
• Sterling emphasizes an operational approach through its Seven Levers methodology, aimed at recurring operational improvement and business building in portfolio companies.
• For founder-owned companies, Sterling highlights equity sharing and economic alignment with portfolio-company employees as part of its partnership model.
