PLAN4 receives 3 million euros to accelerate climate-friendly renovation of existing buildings

  • Shareholders invest another 3 million euros
  • Exploding demand for BuildingCheck, especially among public building owners
  • Solving the renovation backlog to achieve climate targets

Today, the Freiburg-based startup PLAN4 Software announced the completion of a 3 million euro financing round. Capital providers are the previous investors BitStone Capital, Sprengnetter GmbH and Rudolf Müller Medienholding GmbH & Co. KG, Caitano Capital GmbH and several business angels.

With the help of the new financing round, PLAN4 Software GmbH is responding to the exploding demand for their digital tool “GebäudeCheck”. The tool enables customers to conveniently calculate their renovation needs, renovation costs and the associated CO2 savings within a very short time. Last year, the young startup company from Freiburg was already able to increase sales fivefold compared to the previous year.

“Today, we already serve 60 cities and municipalities with our software solution,” explains Thorsten Harig, CEO of PLAN4. “With the new round of financing, we will expand our capacities so that we can respond to the permanently increasing demand,” Harig continues.

By way of background, reducing CO2 emissions from the building stock plays a key role in Germany’s climate policy. Today, 35 percent of the final energy demand in Germany is attributable to the building sector. At the current renovation rate of around one percent, the climate targets cannot be achieved. A higher renovation rate can only be achieved by using digital tools such as PLAN4’s “Building Check”.

PLAN4 Software GmbH is a start-up company from Freiburg im Breisgau. With the tool “GebäudeCheck” developed in Germany, the young innovative company has specialized in the digital evaluation of the renovation effort of existing buildings. With a time saving of about 50 percent compared to conventional methods, customers find out in which condition the building is and with which priority the respective renovation steps have to be initiated. Regional differences, among other things, are also taken into account in the assessment.

The new Venture Partner Michael Kokorniak brings more than 25 years of experience as a founder and software entrepreneur to the round of the Venture Partners Marc Silke and Thomas Knaack. After his engineering studies and subsequent scientific work, he founded the software company Pace Aerospace Engineering and Information Technology together with two partners, which he expanded from a Berlin startup to a globally active group in the field of digitization and decarbonization of the aviation industry until his retirement in 2021. Since then, Michael Kokorniak has been involved as an investor, entrepreneur and consultant in various promising technology sectors.

Daniel Pölt, on board as Investment Manager since February, studied at WHU – Otto Beisheim School of Management and at the University of North Carolina at Chapel Hill in the USA. He started his career in 2017 at the consultancy Simon-Kucher & Partners, where he supported clients from the banking and insurance sectors on topics related to price/product optimization, digital sales models and monetization strategies, most recently as a manager.

Last but not least, Jakob Schulz will support the company as an investment advisor in the future. Besides his task at Bitstone Capital, he works with medium-sized companies and family offices on the topics of venture, real estate and PropTech at the Matuschka Group.

Green Fusion receives additional funding to optimize complex energy systems of buildings

  • BitStone Capital, FutureProp, Marc Stilke and other angel investors expand investor base of Green Fusion in addition to existing shareholders High Rise Ventures, Vireo Ventures and other strategic angel investors.
  • The funding will be used to further develop the energy management software and bring it to market, with an objective of strengthening inefficient heating systems in existing buildings to reduce CO2 emissions.

Berlin, February 2022 – Green Fusion has been able to convince further renowned investors from the proptech sector to invest in its intelligent control software. In addition to venture capital investor BitStone Capital, which invests primarily in the real estate tech sector, industry-experienced business angels and the family office FutureProp expand the investor team. The next phase of development will increasingly focus on the digitization and optimization of existing energy systems in the housing industry.

Optimize entire real estate portfolio – „Digitizing and analyzing heating systems is only the first step on the way to efficient operations,” summarizes Green Fusion co-founder and CEO Paul Hock. „In most cases, however, there is a lack of capacity and the necessary engineering knowledge to optimize the systems after evaluation, as well. Green Fusion enables remote access to all plants and, in the future, automated optimization without manual intervention on site. This can save resources, travel time and, most importantly, CO2 emissions.“

With Green Fusion’s interoperable, modular approach, monovalent systems such as gas boilers or district heating systems will increasingly be optimized and integrated into the cloud platform in the future.

Marc Stilke, Venture Partner of BitStone Capital and Business Angel, adds: „We were convinced by the combination of an excellent, complementary team and the intelligent approach to optimize hybrid energy systems in existing buildings. This is a huge market potential and a key driver of the energy transformation.“

About Green Fusion – Founded in January 2021, the startup Green Fusion develops a cloud-based energy manager for the intelligent control of heat, electricity & e-mobility. The focus here is on hybrid heating systems in buildings such as heat pumps, solar thermal systems or gas boilers and the coupling to photovoltaic systems and e-charging columns, as they are increasingly used for example in quarters. Further, the energy management software also allows existing systems to be operated more efficiently through visualization and remote control. In the future, Green Fusion will use machine learning to increase system efficiency and prevent outages with predictive maintenance. Green Fusion helps its customers to reduce CO2 emissions and operating costs, increase security of supply and reduce maintenance and operating costs. The first projects in the real estate industry have already been successfully implemented.
