To address the problem, Sheldrick teamed up with his friends Mohan Ganesalingam, a mathematician, Jack Waley-Cohen, a linguist and Michael Dent and co-founded location technology company what3words in 2013. London-based what3words is enabling people around the world to identify and share any precise location using just three words. The three-word addresses are easier to remember than a postal address and can be shared more accurately than any other location reference system. It is also the first addressing system entirely optimised for voice, allowing for the easiest and most human-friendly possible input. For example, Sheldrick’s business card mentions ///filled.count.soap which marks the exact entrance to what3words’ London headquarters. The other side of his business card has an address ///dancehall.flatbreads.retire, which takes one to a beach in Philipsburg, the capital of Dutch Caribbean island of Sint Maarten, where three-word addresses are solving the pizza delivery challenge. It means that every house on Sint Maarten, as well as every beach chair, now has a reliable and accurate address for pizza delivery.
