Jan 4, 2021

Charlottesville, VA — January 4, 2021 — Quad-C Management, a leading middle market private equity firm, today announced that it has recently completed majority investments in Learners Edge and Astrix Technology Group and sold Inmark.  Learners Edge is an online training and certification platform that provides end-to-end education and professional development for K-12 teachers. Astrix Technology Group is a specialty consulting and staffing firm focused on serving scientific and laboratory environments across the private and public sectors. Inmark is a leading distributor of rigid container and life sciences packaging.

Quad-C had a productive 2020 on the new investment front with four new platform investments and significant add-on activity across the portfolio.

“Education and human capital management have been long-term focus areas for our business and consumer services practice,” said Tim Billings, Partner at Quad-C. “We see a number of parallels between these companies and our investments in Colibri Group, Rainbow Early Education, Vaco and S.i. Systems.  We feel fortunate to be partnering with exceptionally talented management teams at both Learners Edge and Astrix.”

“Both of these companies operate in high-growth end markets with multiple avenues to achieve above market growth,” added Jack Walker, a Partner at Quad-C. “Our strategy will include expanding the geographic footprint of these companies both organically and through acquisition, broadening our service offering and investing in human capital and technology to support accelerated growth.”

Quad-C was also busy selling in 2020, with the sale of Inmark representing the second successful exit of the year. “During our nearly five-year investment, we formed a terrific partnership with management and leveraged our expertise in packaging and healthcare to help accelerate growth,” said Frank Winslow, Partner at Quad-C. “As a result, not only did earnings grow at a double-digit CAGR, but Inmark was also able to move into higher value segments of the market. We are thrilled with the outcome of our investment.”
