Founded in 2003, Argonne Capital Group is a closely-held private investment firm that seeks to make equity investments in a diverse range of middle market enterprises. Unlike traditional private equity firms, Argonne independently capitalizes each investment it makes, allowing the firm meaningful flexibility in the types of transactions it pursues and an indefinite time horizon for its ownership of any given asset. This flexibility has made Argonne a preferred acquirer in situations involving closely-held companies or unique deal dynamics. Since inception, Argonne has completed 55 acquisitions, and today, boasts a portfolio that generates $1.6B in annual sales and employs over 24,000 people.
