Berlin-based e-scooter rentals company Tier Mobility has announced a $200 million raise, which it says is the “first close” of its Series D, as investors continue to plough money into urban micromobility. Existing investor SoftBank Vision Fund 2 is co-leading the Series D with the UAE-based Mubadala Capital, which also backed Tier’s Series C last year, while other existing investors RTP Global, Novator, White Star Capital, Northzone and Speedinvest also participated.
