suena energy secures €8 million Series A funding
Hamburg, 18 September 2025
TUHH start-up drives energy transition forward
The Hamburg-based start-up suena energy, which emerged from the Hamburg University of Technology (TUHH), has raised €8 million in a Series A financing round, thereby continuing its growth trajectory. The company was founded in 2021 by TUHH alumni Dr Lennard Wilkening, Miguel Wesselmann and Tom Witter and is based on research conducted at the TUHH. suena received support early on from the Startup Port @TUHH start-up centre and programmes such as the EXIST start-up grant.
With its cloud-based optimisation software suena opt, the young company is developing a solution that optimises the techno-economic operation of large-scale battery storage facilities, solar parks and wind farms. The software creates real-time operating schedules, integrates forecast models and AI, and thus enables the simultaneous use of multiple markets and applications.
The aim is to increase the efficiency and cost-effectiveness of energy storage systems, facilitate the integration of renewable energies and reduce battery ageing. In this way, suena is making an important contribution to the energy transition and to making European energy markets more flexible.
The new Series A funding will be used primarily to further develop the software, scale up to the European market and expand the team. Suena also plans to implement further pilot projects with operators of large storage facilities and energy suppliers. Together with new investors Eneco Ventures and 4impact capital, as well as existing partners InnoEnergy, J.O.S.S., Santander Asset Management and Energie 360°, sunea is ready to push boundaries and explore new opportunities.
For the TUHH, this success is a prime example of how scientific research can be translated into marketable innovations. At the same time, it demonstrates the importance of targeted start-up support for the transfer of ideas from universities to industry.
Suena energy thus represents the growing importance of deep tech start-ups from the scientific community, which are not only economically successful but also make a decisive contribution to solving key issues for the future, such as sustainable energy supply.
