It's a fundamental logistical problem: not everyone, or everywhere, has a traditional address, and GPS coordinates can be tough to use. While working in the music industry, Chris Sheldrick noticed that bands and equipment kept getting lost on the way to gigs, and he took up the mission to create a better addressing system for the world. He worked with a mathematician friend to devise the what3words algorithm that has named every 3-metre square in the world. Started in 2013, the system is being used by eight national postal services, and has a range of integration partners across the world in fields as varied as humanitarian aid, logistics, and in-car navigation.
