THE DIFFERENCE: OUR BACKGROUND
Combining two decades of energy and sustainability innovation
Over 20 years of hands-on experience in energy management and sustainability software come together at ecolyptus. Founded by Antonio Ruzzelli, who previously built and scaled a leading energy platform across global markets, and joined by sustainability SaaS entrepreneur, Callum Miller, our team understands both sides of the challenge.
Antonio Ruzzelli
Chief Executive Officer & Founder
Antonio Ruzzelli is an entrepreneur and computer scientist with over two decades of experience at the intersection of energy and climate innovation. After completing his PhD in Computer Science at University College Dublin, he founded an energy analytics software company that served clients in more than 50 countries before being successfully acquired. Five years later, Antonio saw a persistent gap in the market: while sustainability was often referenced in energy management software, it was never fully integrated to enable truly unified decision-making. That insight became the driving force behind ecolyptus.
Callum Miller
Chief Operating Officer
Callum Miller is an experienced entrepreneur in the sustainability technology sector, having built and scaled a SaaS business that supported hundreds of clients in achieving their ESG goals. Through this work, he observed first-hand how many organisations continued to struggle with managing energy effectively in the context of their net zero commitments and became determined to close that gap. This drive led Callum to join forces with Antonio Ruzzelli, combining their expertise in energy management and climate innovation to create a new generation of software that fully integrates sustainability and energy.
