Summary
Nonantum Capital Partners ("Nonantum") has been named to Inc.'s 2023 Founder-Friendly Investors List, according to a Business Wire release issued by the firm. The annual list honors private equity, venture capital, and debt firms with the best track records of success backing entrepreneurs.
Inc. based the rankings on direct feedback from founders. Entrepreneurs who had sold to private equity and venture capital firms completed a questionnaire about their experiences with those investors and shared data on how their portfolio companies grew during the partnerships. Inc. editor-in-chief Scott Omelianuk said founder-led companies increasingly need financing partners that offer "guidance, expertise, and understanding—not just capital."
Nonantum describes itself as a private equity firm led by experienced private equity and management executives. Formed in 2018 as a spin-out from Charlesbank Capital Partners, the firm invests across North America with a focus on family- and founder-led businesses, corporate carve-outs, and complex situations. Its team reports decades of investment and operating experience across business services, consumer products, and industrials. The firm states that its founding partners grew up in family businesses, and that for most of its portfolio, managers favored Nonantum over competing acquirers for reasons other than price.
Managing Partner Jon Biotti said the firm's "partnership approach" involves leveraging its experience in a hands-on manner without micro-managing, guided by integrity, humility, and teamwork. The release is a company announcement and the rankings reflect Inc.'s survey methodology as described in that release.
The 2023 list is available on Inc.'s website. Inc. also named other private equity firms in later years, including Palm Beach Capital (2024) and Comvest Private Equity (2025), per related Business Wire releases.
