Who we are:
Joining Popsa right now is pretty exciting. According to Deloitte, we are one of the UK’s fastest-growing tech startups, and previously ranked by the Financial Times in the Top 5 fastest growing software companies in the whole of Europe.
We have the backing of some of the best investors in the world. Our native iOS and Android apps are available in 12 languages – attracting more than 4 million users to date–and we ship to over 50 countries around the world.
People have never taken more photos than we do today. Our phones are crammed with memories. But although we’re good at capturing moments – we’re not as good at doing anything with them. They’ll often sit forgotten on our devices or in the cloud, shrouded in screenshots, receipts and pictures of where we parked the car.
Founded in 2016, we’ve already built an award-winning app that’s made printing your memories so easy and accessible, anyone can do it. No more barriers. No more time-wasting. In fact, everything we do as a business is designed with this ethos. We help people turn their best moments into something beautiful and lasting, in no time at all. But this is just the start...
Today we’re best known for photobooks, but our vision of the future goes far beyond this.Popsa is building a new generation of services that combine artificial intelligence and thoughtful design to support a healthy processing of the meaningful events and relationships in your life.
