After Apple booted Google Maps from iOS last year, Daniel Graf led the development of a beautiful, refreshed mapping experience that shot to number one in the iTunes store and kicked Apple’s ass on its own turf. Here’s how Graf made it happen—in his own words:

“We have a very successful Android version of Google Maps, so the easiest thing to do was to say, this is super-successful, users love it, so why don’t we just port it over to iOS? But I wanted to challenge the team. While the Android version is a great product, you can also tell it’s been around for a while. You have to access everything via menus—it’s not really best-use-case driven anymore. I said, let’s take a step back—what if we could start from scratch and forget anything we’ve ever done? We have the foundation—the Google data, the mapping data, the local business data, the imagery, the navigation algorithms—it’s a dream to start with.”
