We only buy the bestA bit more about TapTap was founded in late 2020 by two charging software experts, Nico and Dan, who saw that the charging UX for EV drivers was broken. They bootstrapped their way to building 2 key products: a driver app that enables really simple payments on a huge network of chargers; and a platform for charger owners and installers to manage their chargers and collect payments. Tap is live in the Netherlands, Belgium, Ireland and the UK with tens of thousands of satisfied users (our 4+ App store ratings prove it). At Tap, we believe that the intersection of energy and mobility has unlocked the next great wave of technological innovation, and we are here for it. Join us!
