Circumference Group is an investing platform founded in 2009 by Jeff Fox, former CEO of Convergys Corporation and COO of Alltel Corporation. We are operators and investors with decades of success running and investing in businesses with a bottom up approach.

Across the Circumference Group platform, we engage in public market investing, private co-investing and strategic and operations advisory services. We use our time-tested, operations-based framework, which we call the Core Value Assessment, to drive our research and analytics.

Public Market Investing

The Circumference Group LLC is an investment manager focused on public companies capable of generating substantial free cash flow but challenged by the market’s continuous sequential growth requirements. We specialize in business to business services and technology companies, engaging with management as knowledgeable peers with operational insight and patient capital. Circumference Group’s public market investing team is led by:

John Haley, Co-Chief Investment Officer
John Lammers, Co-Chief Investment Officer

Private Investing and Consulting

Circumference Group opportunistically invests internal capital in private equity and other alternative assets through co-investments that benefit from our operations experience and long-term investment horizon. We conduct extensive research on the opportunities we consider. Using our Core Value Assessment, we dig deeply into how companies are constructed to identify value-creating priorities. We complement private investments with strategic and operations advisory services to co-investment partners, private portfolio companies and other third parties. Our consulting services include pre-investment diligence support and operations planning and execution support.
