Münchner Climate-Tech Startup Tanso gets 12 million euros

The Dutch B2B investor Henq and the Belgian VC Fortino Capital have cited the Series A financing round at Tanso. The German VCS Capnamic and UVC Partners have expanded their participations.

Tanso Technologies, a climate-tech startup from Munich specializing in industrial sustainability software, has completed a Series A financing round over 12 million euros. The round was led by the Dutch VC Henq and the Belgian B2B-Saas investor Fortino Capital, existing investors Capnamic and UVC Partners also increased their investment amounts.

One month after the foundation, in September 2021, Tanso had already started 1.6 million euros in pre-seed capital. At that time, the round was led by UVC Partners, supported by Picus Capital, Possible Ventures and several Business Angels. Among them: managers from the HR startup Personio and the robot company UIPATH.

Goal: European market leader in the ESG software segment for industrial companies

Tanso has developed a SaaS platform that helps companies calculate and reduce their CO₂ emissions. The TÜV-certified platform shows both corporate carbon footprint (CCF) and Product Carbon Footprint (PCF).

With the CCF module, a company can automatically calculate how much CO₂ emits it at all locations-from direct emissions (e.g. machines) to indirect (for example by suppliers or travel). The PCF module particularly helps to measure how much CO₂ creates in the manufacture of individual products.

Tanso wants to significantly enlarge the team with the fresh capital, from currently 55 to over 100 employees. The startup also wants to open up new international markets outside the roof space and drive the development of additional modules-for example for supply chains, legal requirements and risk management. At the same time, the Tanzo team wants to rely more on AI applications, for example with its own AI Copilot.

Benefit from the CSRD directive

Through the EU-wide corporate sustainability reporting directive (CSRD), companies have been obliged to disclose ESG indicators in their annual reports since 2025. These include CO₂ emissions, social standards and governance structures.

Tanso aims at industrial companies and the producing middle class, which are particularly challenged due to complex supply chains and internal barriers to present such reports. The software should automate data collection, minimize Excel-based manual processes and identify specific savings potential.

According to its own information, Tanso says over 300 customers in more than 40 countries, including Kärcher, Duravit, Paulaner and Goldbeck.
