Relevant Solutions, a portfolio company of Fusion Capital Partners, has acquired Conrad Kacsik Instrument Systems for undisclosed terms. Founded in 1977, Conrad Kacsik provides thermal-processing control system engineering, calibration and metrology services to aerospace, automotive and medical customers. Headquartered in Solon, Ohio, the company operates an ISO/IEC 17025:2017 accredited calibration laboratory supporting AMS2750, Nadcap and CQI-9 compliance standards.

The acquisition represents Relevant Solutions' second add-on since partnering with Fusion Capital Partners in 2025, following its acquisition of Automation Werx earlier this year. Fusion Capital Partners is a Los Angeles-based private equity firm pursuing control-oriented investments within the industrials sector.

CEO Chris Miller will remain with Conrad Kacsik, working closely with the Relevant team through the integration. The company's team will join Relevant's "Family of Companies" while maintaining its established expertise in highly regulated industries where thermal-processing accuracy is mission-critical.
