Jomicon GmbH is a privately held company founded in 2018 by Thomas Kercher. It works with businesses at an inflection point in three ways: advice from an operator (Advise), interim and fractional management with full operational responsibility (Run), and investment and co-building alongside the team (Own). Its roots are in renewable energy and owner-led Mittelstand companies. ### Who is Thomas Kercher? Thomas Kercher is the founder and managing director of Jomicon. He brings more than two decades of leadership experience in renewable energy: CEO of Pfalzsolar, COO of Greencells Group, and Co-CEO and shareholder of FEBESOL, which Thermondo acquired in 2024. He has led companies in Germany, the United Kingdom, the Netherlands, the United States and beyond. ### What is the difference between interim and fractional management? Interim management is a full-time executive role, typically for six to twenty-four months, as CEO, managing director or board member, for example during a transformation or a gap in leadership. Fractional management is part-time senior leadership, usually as CEO or COO for a set number of days per month, for as long as it adds value. ### Which companies and sectors does Jomicon work with? Mainly companies in renewable energy and adjacent sectors, such as solar PV, EPC contracting, residential energy installation and energy services, and owner-led Mittelstand companies that are ready for their next stage. Jomicon is based in Germany and works across the DACH region; Thomas has also led businesses across Europe, the Middle East and North America. ### How does Jomicon charge for its work? Through monthly retainers with an agreed number of days, fixed-price projects where the scope allows, and, where it fits, a fee component tied to agreed results. Jomicon prefers to be measured by what changes inside the company, not by time spent. ### Does Jomicon invest in companies? Yes. When Jomicon sees a strong business whose strategy or structure limits its growth, it can invest, take an operational role and build alongside the team. The FEBESOL engagement is the complete example: strategy work led to a Co-CEO role and a shareholding, and the company was later acquired by Thermondo. ### What happened at FEBESOL? FEBESOL GmbH, a well-regarded residential solar installer in south-west Germany, became a nationwide, vertically integrated solar EPC within about three years, with close to 200 people.
