About Us

TJM is a private investment firm that invests in established middle and lower middle-market businesses looking to substantially grow and realize shareholder value. 

TJM was jointly founded by Tom J. McDonough in 2008 with a vision to unlock capital growth opportunities. TJM has a fully supported management team backed by a select group of committed capital sources – including family offices, high net worth individuals, and a diverse set of first-generation (G1) investors  – as a different type of private investment firm. 

We formed to remove the traditional institutional constraints of private equity funds, which enables greater flexibility in terms of industry, deal structures, and investment time horizons. Our investor partners will have access to successful entrepreneurs, operators, investors, and business leaders who are committed to applying their knowledge gained from direct operational experience, financial resources, strategic support, networks, and sector-specific expertise to help substantially grow businesses and realize shareholder value.
