Our Take on Joby

Joby's small media presence seems to be by design - Joby's team has been working with maximum intensity on bringing the project to fruition and testing their full scale S4 prototype. The company has recently closed large funding rounds - which included investors such as Toyota, JetBlue Baillie Gifford - and is demonstrating strong momentum as it stands up its new manufacturing facility in California. Once the facility is operational, it's likely we will be seeing substantially more news from Joby as it begins testing and certifying vehicles.
