Optimizing costs for companies with on-site power generation

Frankfurt-based startup GmbH secures financing


High-Tech Gründerfonds (HTGF) and 5 Business Angels are investing together just under 1 million euros in GmbH. The company develops software to optimize energy costs for companies with on-site power generation. The funding will be used to further develop the software and to finance the market launch in Germany.

Over a million small power plants went online in Germany in the last 10 years. At first, the electricity from these plants was simply fed into the public grid and paid for with a subsidized tariff. In the meantime, however, it became profitable to establish so-called microgrids and use the energy directly on site. In this way, energy costs can be saved and the strained electricity networks can be relieved.

However, the implementation of the optimal microgrid concept is complicated and time-consuming up to now. “In Germany alone, industrial consumers with existing small power plants are losing savings of well over EUR 100 million per year – and this number is rising quickly” emphasizes Matthias Karger, co-founder and managing director of He adds “even energy consultants and service providers currently have to calculate project per project manually”.

With’s software application opti.node, all steps for the commercial planning and management of microgrids are automated for the first time. The offer aims at energy managers of commercial real estate with on-site electricity generation. Co-founder and CTO Lars Manuel Rinn explains: “In addition to industrial companies, hospitals, business parks and large hotels benefit from the use of opti.node. The software automatically determines the most cost-effective utilisation for the locally generated electricity and provides all the necessary tools for the implementation and continuous management of the microgrid.”

In the current seed-round the young company from Frankfurt received a total of 775,000 euros in growth capital. The capital will to be used to grow the team, for further development of the software platform and to boost market entry in Germany. Dr. Ulrich Schmitt, Investment Manager at High-Tech Gründerfonds explains: “In a decentralised energy world, it is becoming increasingly important to manage local electricity supply and demand efficiently. The technology developed by is the first integrated software-based solution to address this need. We were particularly impressed by the excellent market knowledge and implementation strength of the founders and are pleased to support the team in tapping this fast-growing market.”

In addition to High-Tech Gründerfonds as lead investor, five experienced investors from the FrankfurtRhineMain Business Angels e.V. also participate in the financing round. The fact that was able to convince both, our business angels and the HTGF shows the quality of the start-ups in the Frankfurt area. In this case, a practice-oriented innovation and an experienced founding team build a perfect match. We are particularly pleased that this is a product for better and more efficient energy use, as we are devoting increased attention to this sector” comments Dr. Burkhard Bonsels, board member of Business Angels FrankfurtRheinMain e. V., who is also participating in the financing round personally.
