Review: The Spark 2021

With the topic “Net Zero Tech” this year, we honored start-ups that are already taking an important and decisive step towards climate neutrality.

In addition, with the Female Founder Award, we honor founders who, as digital pioneers, encourage more women to take the step into founding a company.

The award ceremony

On November 11, 2021, ten pioneering digital companies competed as finalists in the Tipi, Berlin and presented themselves to over 200 invited guests from politics, business and science.



OroraTech is developing the first global space-borne forest fire intelligence service, including risk assessment, early detection, real-time monitoring and damage analysis. By using New Space technologies, the company wants to help shape a sustainable future.



DABBEL was founded in 2018 with a mission to develop the most scalable, cost-effective and sustainable software to drastically reduce CO2 emissions in commercial buildings worldwide as quickly as possible. With the DABBEL KI software, CO2 emissions can be reduced by up to 40% in less than 4 weeks – completely without additional hardware.



Circunomics is the first cloud-based IoT marketplace for battery reuse and recycling with a vision of a circular economy. With artificial intelligence, the platform simplifies and optimizes the return and remarketing of e-vehicle batteries for a sustainable use of resources.



Concular has developed software that can be used to digitize materials in buildings so that they can be moved to new buildings in the event of demolition instead of being deposited. This saves CO2, waste and resources.


Inspiring the masses for electromobility – elvah meets this requirement. With its uncomplicated app including recommendations for the best charging experience and a charging flat rate for electric cars, the company offers its customers provider-independent and digital access to all public charging stations in Germany and 30 other countries.

The Swiss start-up is active in the trading of renewable energies. It offers a set of tools that enable structuring and transparency when pricing so-called Power Purchase Agreements (PPA). It provides market analysis, continuously monitors energy sales and risks of PPA deals and renewable energy assets. Energy sellers thus gain more fairness on the energy market. PEXAPARK has more than 50 employees and is already active in 18 markets.


How big is our carbon footprint? Companies can get the answer to this question in detail with the software solution from the company founded in 2019. The data collection for footprint measurement is fully automated and the results are visualized in real time. This forms the basis for CO2 management and the definition, implementation and tracking of the climate strategy.


TESVOLT is the technology leader for energy storage solutions for trade and industry. Over 2,200 storage projects have already been delivered worldwide. TESVOLT storage can be combined with all regenerative energy sources and is mass-produced in Europe’s first gigafactory for battery storage at the Wittenberg site.




TeleClinic enables patients to have an online visit with a qualified doctor who can issue them with prescriptions and sick notes via an app. Katharina Jiinger founded TeleClinic at a time when online visits to the doctor were still forbidden in Germany and digital prescriptions and digital sick notes were still a thing of the future. Today, 7 years after its foundation, the market is completely liberalized and TeleClinic treats hundreds of patients online every day.



Mengting Gao wants to create meaningful connections for people across national borders and cultural differences – with Kitchen Stories we succeed every day through one thing that connects us all: cooking.



Demodesk is the first intelligent meeting platform for sales teams.
