Tau Secures €4.5 Million Series A Funding from ALTANA Group

Electric mobility and advanced materials venture to accelerate product development and strengthen team

Turin/Berlin/Wesel, March 4, 2020 – Turin-based e-mobility and advanced materials venture Tau has secured a €4.5m series A equity investment by the corporate venture arm of ALTANA Group, the German specialty chemicals company.

The visit of Tau R&D site in Turin in July, 2019 “We are excited about welcoming ALTANA Group as an additional investor who shares our vision for the core of e-mobility by achieving the transition of wire coating towards a sustainable process and by delivering disruptive change in form of next generation technologies and high-performance materials”, says Dr Daniel Rutz, Chief Development Officer of Tau. Tau’s proprietary DryCycle® and LILIT® technologies meet the demands of electrical automotive engineering for ever smaller, lighter and yet more powerful and reliable electric motors. DryCycle technology offers higher performance, greater sustainability and stronger reliability in wire enamelling. By using only solvent-free polymers, DryCycle reduces the production of harmful VOC during the coating process and lowers carbon dioxide emissions. “We at Tau believe in bringing peace-of-mind to different stakeholders in electric mobility”, explains Francesco Taiariol, Tau’s CEO and co-founder. “To the rapidly changing electric vehicles producers, we bring the electrical, mechanical, thermal and chemical resistance that they demand. Think of high voltage, SiC powered, partial discharge and high filling factor for electric drive trains. To production process operators, we bring simplicity, flexibility in terms of rectangular, square or round geometries, state-of-the-art controls, the elimination of harmful substances and the reduction of scrap that they crave for. And to our children, we bring a minimized carbon footprint, a generally sustainable use of resources and an overall contribution to the change that we all think is necessary.” ALTANA’s division ELANTAS, a global market leader in the field of enamels, will help accelerate Tau’s product development and contribute their knowledge and experience in the synthesis and analysis of polymers used as electrical insulation materials. “Tau’s technological solutions are spot-on with the increasing demand by electric mobility for higher performance wire, and we are excited to work with them. The investment reflects our continuous desire to be at the forefront of innovation and to embrace change towards sustainability. Our collaboration with Tau will contribute to our ability to assist our customers’ transition to greener and more efficient processes”, says Volker Mansfeld, Head of Business Development of ALTANA AG. The series A financing builds upon Tau’s rapidly growing momentum with product development and with automotive and energy OEM & tier 1 suppliers. As part of the transaction, ALTANA AG invests up to €4.5 million for a minority stake and a board seat, and its division ELANTAS enters a joint development agreement with the venture.
