Deal: Wenger Vieli advised DePoly on seed financing round extension

Wenger Vieli advised DePoly, a cleantech company transforming polyester and PET waste into valuable raw materials, in all legal matters in connection with its seed financing round extension, bringing the total fundraise to USD 23m. The funds are intended to support the launch of DePoly’s 500-tonne-per-year showcase plant in Monthey, Switzerland, and enable the company to scale towards its first commercial plant by 2027.

Its innovative approach supports a circular economy by reducing waste and reliance on fossil fuels, and it positions the company at the forefront of the sustainable plastics industry.

The team was led by Michael Baier (Partner, Corporate/M&A) and included Dominique Mattmann (Senior Associate, Corporate/M&A) as well as Dario Schönbächler (Associate, Corporate/M&A).
