About Enneo

Enneo is the first AI-powered omni-channel customer service platform designed specifically for the utility industry’s technological and operational needs. By leveraging industry-optimized, best-in-class AI models, Enneo drives intelligent automation that boosts both service team efficiency and happiness and customer satisfaction.

Founded in 2022 by Dr. Kyung-Hun Ha and Dr. Richard Lohwasser, who previously co-founded, scaled, and exited the blockchain-based neo-utility Lition Energy, Enneo was born from first-hand experience. After years of witnessing systemic customer service challenges at large and mid-sized utilities, they decided to build the solution themselves.

Since then, Enneo has become a recognized name across the German energy sector, with several of the country’s largest utility providers already among our customer portfolio or actively joining it.

Our goal is to become the leading customer service platform across the 'DACH'-region, enabling true digital transformation in the utility sector at large, improving experiences for both energy companies and their customers, and freeing up time for what truly matters.
