29/05/2025

L Squared Capital Partners platform company CogneSense has acquired Dublin-based air quality, environmental noise and vibration monitoring solutions provider Sonitus Systems. 

CogneSense, a USA-based measuring and control instrument manufacturer, is currently undertaking a ‘buy and build strategy’ in the environmental sensing and measurement area. As the second acquisition for CogneSense, the addition of Sonitus Systems to the platform’s portfolio will enhance its integrated environmental monitoring solutions aimed at improving public health and safety, promoting sustainable practices and enhancing operational efficiency. Alongside improved air quality, noise and vibration sensing capabilities, the acquisition also provides CogneSense with a proprietary cloud platform designed for real-time observations. 

Paul Dhillon, CogneSense CEO, commented: “We are thrilled to welcome Sonitus Systems to the CogneSense team. Their innovative approach to environmental monitoring aligns perfectly with our vision of empowering a healthier future and planet by protecting our shared environment and public health through innovative and sustainable measurement, monitoring and control 
solutions.” 

Paul McDonald, Managing Director at Sonitus Systems, said he was “thrilled to collaborate with L Squared and CogneSense”. He added: “Together, we will leverage cutting-edge technologies, enhance our offerings and provide even greater value to our loyal customer base. I am also deeply grateful to my team and the visionaries who laid the groundwork for our success.” 

CogneSense anticipates several additional acquisitions to be completed in 2025, with a focus on the environmental and health and safety end-markets. As the year progresses, the platform expects to partner with Internet of Things (IoT) manufacturers, monitoring application providers and sensor, measurement and control equipment manufacturers to further improve its portfolio.
