About Tender365



Tender365 was initiated in the middle of 2017 as an idea of four energy supply companies as part of a design sprint led by EXXETA. From the very beginning, the idea was to get various companies from the sector inspired about the platform through the opportunity to participate in Tender365. The platform’s test version was available in summer 2017 and continued to develop further through the participation of energy suppliers and municipal utility organisations.

The platform is operated by Tender365 GmbH located in Leipzig. The founding shareholders of Tender365 GmbH are the initiators EXXETA AG and GasVersorgung Süddeutschland GmbH as well as eins energie in sachsen GmbH & Co. KG. Further potential stakeholders are also ready to join the company and corresponding negotiations are in progress.


A characteristic of the company is that the shareholder combine various market roles of the energy market. EXXETA, as an IT solution provider active in the energy sector, but also in other sectors such as automotive and finance, ensures quality and topicality of the platform. GVS, eins energie and Gas-Union, as innovative energy companies, contribute their experience in the areas of trading, procurement and sales as well as their networks. Due to their experiences in the market, they are aware of the challenges in the commodity business and of customer requirements.

The company is led by directors Frank Sonne (EXXETA) and Helmut Kusterer (GVS). The Tender365 team is being strengthened by Markus Jungmann for Business Development & Sales as well as Andreas Langer as Product Owner for the platform software. All four are available to you to answer your questions and are responsible for the reliable operation as well as functional and technical development of the platform.

We are open to any suggestions you may have. You are warmly invited to become a part of the company and join us in taking the platform to even greater heights.
