About Hello Retail

Hello Retail started its journey in 2013, to become today’s e-commerce personalization platform that helps merchants across the globe stay relevant in a competitive market, maximize profits, and create unique experiences tailored to each visitor.

At the beginning of 2023, we announced our innovative predictive software – Product Intelligence – which has become the AI backbone of our personalization platform. The world and the e-commerce climate are ever-changing, and we aim to empower our customers who want to be at the forefront of innovation.

Today, we are almost 70+ people based in Copenhagen with different nationalities which gives a great, international atmosphere. We are relaxed but ambitious, we have fun but know when to work. We cooperate but are fully aware of the value of being self-driven and motivated.

If you do not know Copenhagen already, the capital of Denmark oozes of atmosphere, lots of shopping, restaurants and cafées, and cool hangout places. You can cross Copenhagen by bike or electrical scooter in no time to go for street food, maybe even kayaking in the canals, or ice skating in the wintertime.

Our brand new office is only a 5-minute walk from the Copenhagen Central Station. If you live in Southern Sweden you can tag along our other employees living in Sweden going by train from Malmö to Copenhagen daily. We have made it as easy as it gets.
