Frequently asked questions
Who runs investment decisions at Nonantum Capital Partners?
Jon Biotti serves as Managing Partner and Chief Investment Officer and leads the investment team. He is supported by Managing Directors David Ganitsky and Alex Weiss, along with a group of principals and senior associates. The firm lists an executive-partner bench that includes Neil DeFeo, Ron DeFeo, and Kathleen McCann as part of the deal-evaluation and portfolio-support structure.
Does Nonantum participate in fund commitments or only direct deals?
Nonantum operates as a direct-control private equity firm that invests out of committed fund vehicles. The firm closed Fund II at $575 million (per the firm, early 2026) and deploys that capital into platform acquisitions and growth partnerships. It does not present itself as a fund-of-funds or LP in third-party vehicles.
How is Nonantum related to Charlesbank Capital Partners?
Nonantum was formed in 2018 as a spin-out from Charlesbank Capital Partners. The founding team, led by Jon Biotti, took its middle-market investment track record — including deals in consumer, industrial, and business services — and applied it to a new independent platform. The firm’s website lists its prior Charlesbank-era investments under a separate section labeled ‘Prior Experience.’
What investment stages and check sizes does Nonantum typically target?
The firm targets lower-middle-market companies with enterprise values between $50 million and $500 million, writing equity checks from $25 million to $100 million. Its posture is control-oriented, focusing on family- and founder-owned businesses, corporate carve-outs, and complex situations where it can partner directly with management to drive operational change.
Which sectors does Nonantum explicitly avoid?
Nonantum does not publish an explicit exclusion list. Its stated verticals — consumer, industrial, and business services — suggest it stays away from sectors such as deep-tech, life sciences, or financial services, but no confirmed negative screen is publicly available.
What is Nonantum’s known posture on co-investments alongside external GPs?
The firm does not publicly disclose a dedicated co-investment program or LP co-investment vehicle. Its fund deployment model relies on control acquisitions and growth partnerships underwritten by the internal team and its executive-partner bench, rather than club deals with other sponsors.
What is the significance of the executive-partner bench at Nonantum?
Nonantum lists three senior operating executives — Neil DeFeo, Ron DeFeo, and Kathleen McCann — as full-time Executive Partners who sit alongside the investment staff. In a firm of 24 people, this ratio signals that operational due diligence and portfolio-company support are core to the sourcing and value-creation model, particularly for the complex, relationship-driven deals the firm targets.
