Tanso’s latest €4 million seed funding round is led by Cologne-based investor Capnamic. Existing investors such as UVC Partners are also expanding their investments.
The Munich-based company enables businesses to determine their carbon footprint. Tanso operates in a rapidly growing market: until now, only large corporations have been subject to reporting requirements for CO2 emissions. From 2025 onwards, however, every company with annual revenue exceeding €40 million, a balance sheet total of €20 million or more than 250 employees must calculate and publish their own carbon footprint as part of regular annual reporting.
Alexander Kiltz, Principal at UVC Partners, says:
“Through initiatives such as the EU directive on corporate sustainability reporting (CSRD), we are seeing increased industry demand for solutions like Tanso’s. In particular, medium-sized companies with limited sustainability resources benefit from the Climate Intelligence Suite to meet reporting obligations and become more sustainable. We are excited about the entrepreneurial development of the founding team and look forward to supporting the company on its continued growth path.”
Tanso: “We must think about decarbonization holistically”
Tanso was founded in 2021 by Gyri Reiersen, Till Wiechmann and Lorenz Hetzel. As early as October of that year, the startup secured a pre-seed funding round of €1.6 million from UVC Partners, Picus Capital and Possible Ventures. The team now has around 20 employees.
Gyri Reiersen, co-founder and CPO at Tanso, says:
“We must think about decarbonization holistically, with CO2 accounting at both company and product level – only then can we achieve our goals. Competitive advantages through emissions reduction, for example through switching energy sources or suppliers, can only be achieved if you can demonstrate that your own products are better than the alternatives.”
