U.S. electric bus maker Proterra continued its money-raising streak with a $155 million round announced Wednesday in Germany. Automotive giant Daimler co-led the round with Tao Capital Partners, Nicholas Pritzker’s family investment office, which had invested previously. G2VP participated as well. New capital will help Proterra’s quest to electrify the entire bus sector, but this deal comes with a business opportunity: Proterra and Daimler “have entered into an agreement to explore the electrification of select Daimler heavy-duty vehicles,” the companies said in a statement.
