Extra Ordinary

Android Developer

We are a team of ordinary people, doing extraordinary things.

We started Kontakt.io in 2013 with an #ExtraOrdinary goal: to help the visually impaired navigate public spaces. Soon we’ve learned that any individual or business can benefit from beacon technology. Over the years, we’ve attracted over 14,000 clients and 8 million dollars of venture capital, but we’re still hungry for more. We want to learn more. Change more. And achieve more. We wouldn’t be able to revolutionize the way companies and people interact with each other, without #ExtraOrdinary people. Become one!
