Bolt is one of the fastest-growing startups in Europe, having raised $200M at $1B valuation in the latest investment round backed by strong industry-savvy investors like Didi Chuxing and Daimler. The company is growing at a 20% monthly growth rate as we’re capturing a sizeable segment of $1500bn transportation market – an industry attracting interest from some of the biggest global tech investors. As today on-demand transportation only counts to 3% of global transportation, we’re just getting started.

We believe in a future with less car ownership and flexible urban mobility. To be successful in that vision we need to solve many technological challenges. We are leveraging AI in routing and pricing, demand and traffic prediction, reengineering maps to allow pooling and improve navigation, tuning the real-time matchmaking system needs to make thousands complex real-time decisions every second, and of course all of that needs to scale up to tens and hundreds of millions of users. On top of that there is the electric vehicle revolution and the autonomous driving that looms in the near future.

Come help us make this happen!
