TIER Mobility is Europe’s leading shared micro-mobility provider, with a mission to Change Mobility for Good. By providing people with a range of shared, light electric vehicles, from e-scooters to e-bikes and e-mopeds, powered by a proprietary Energy Network, TIER helps cities reduce their dependence on cars. Founded in 2018 by Lawrence Leuschner, Matthias Laug and Julian Blessin.

Recently we have closed a financial transaction to merge with Dott. Together we create the European champion of shared micro-mobility, with revenues of €250m, supporting over 125M trips a year in more than 20 countries. Following this closing, teams across TIER and Dott will be progressively integrated. There has never been a more exciting time to join this ride!
