Charles and Kalle met during their Master’s program in Business Administration (MBA) at the Berlin School of Economics and Law. As they delved deeply into the business aspects of financial planning, accounting, entrepreneurship, supply chain and operations management, marketing, and international business strategy, they developed a friendship, recognized their complementary skill sets, and discovered a shared passion for tackling complex projects aimed at a sustainable future. Inspired by the growing demand for sustainable energy solutions, they decided to combine their expertise and found a solar consulting company focused on simplifying the path to renewable energy for multi-family buildings.
