Bill Spohn welcomes Julien Stamatakis, co-founder of Attune (formerly SenseWare). Julien shares his journey from working on sensor networks for Parkinson's disease detection during his PhD in Belgium to co-founding a company focused on monitoring the built environment. Initially, their sensor technology aimed at the medical field faced funding challenges, which led them to pivot towards the built environment. They began by collecting energy data and expanded to include various sensors to monitor air quality, occupancy, and energy usage in commercial buildings.

Julien discusses the evolution of their sensor technology, highlighting how customer needs have shaped their development. Starting with energy data collection, they moved on to monitor particulate matter and CO2 levels, especially during events like wildfires and the COVID-19 pandemic. Their focus has remained on commercial applications, where robust, long-lasting sensors are critical. Julien notes the challenges in the residential market, including higher competition and the need for low-cost solutions, which differ significantly from commercial requirements.

The conversation also delves into the use of AI and machine learning to enhance data analysis and decision-making in building management. Julien explains how AI helps automate tedious tasks and provides actionable insights from vast amounts of data collected from sensors. He emphasizes the importance of continuous monitoring and the integration of various data sources, including occupancy and outdoor air quality, to optimize building operations. The podcast concludes with Julien highlighting the value of high-quality data and offering consultation to help customers manage their assets effectively.
