Tau is a technology company at the core of energy transition, decarbonization of energy and electrification of transport.
Tau brings disruptive performance, sustainability & reliability to the copper and steel core of electric motors.
Tau was founded in 2015 by Francesco Taiariol and Filippo Veglia. The company is headquartered in Turin, Italy, with offices in Germany and Russia.
Tau has developed DryCycle® technology, which sets a new standard of wire coating. The strict use of solvent-free polymers eliminates the emission of harmful VOC and greenhouse gases while a simplified production process minimizes the use of resources, reducing energy consumption and waste.
Tau’s LILIT® technology provides the essential inline quality control to assure reliability of polymer insulation in magnet wire and electrical steel. Tau's wire uses less resources and improving the electric vehicles’ efficiency, range and recharge time, notably through superior resistance to partial discharge and accommodating voltages of 800V and higher.
Tau reached an important commercial milestone when its wire products completed diligent validation processes of several automotive OEM and Tier 1 suppliers in Europe, Asia and North America.
Tau is backed by Solvay Ventures, Middle Eastern sovereign wealth funds, the Russian Direct Investment Fund (RDIF), Altana, Finindus, and others. The company raised €9M in a Series B round on Feb 01, 2023. This brings Tau's total funding to $25.6M to date.
