About Loop54

Founded in Stockholm in 2012, Loop54 started life as a search and recommendation related consultancy project for Voddler (the leading Swedish-based video-on-demand platform at the time). Loop54 morphed into a standalone product search engine in 2013, with the company growing and soon becoming cash-flow positive.

In 2015, Loop54 raised $580K in seed funding from Axel Johnson (one of Sweden's leading business groups, employing 19,000 people, and whose investments engage with 1 million customers daily), RECAPEX (based in Stockholm, previous investments: virtual fitting solution for fashion e-tailers, Virtusize), together with Swedish government agency, ALMI Invest, and angel investor, Erik Byrenius.
