The Kelso Difference

Kelso is a North American-focused middle market private equity firm. Kelso was founded on the principles of partnership and alignment of interest espoused by Louis Kelso, the inventor of the Employee Stock Ownership Plan (or ESOP). Louis believed that businesses perform better when a strong alignment of interest exists between management, employees and shareholders through shared equity ownership.

Kelso’s unique history has driven a culture and approach to investing that we believe make us an attractive partner to management teams, owners of businesses and corporations.
