Voypost is a Software development company with a focus on startups and SMEs. Founded in 2018 we started as a startup helping expats to deliver packages to their loved ones in their home countries via people travelling to the same direction. After testing 3 different countries, we found out that the market is too narrow. In early 2019 we pivoted to cross-border product delivery. After testing 10 popular verticals across 6 different destinations, we saw that the market was overwhelmed by offering. Thanks to dozens of experiments we had launched to validate our assumptions, we managed to cut 60% of redundant code, design a scalable architecture and establish a rapid delivery process. This helped us to continuously deliver new features in less than a week and have multiple experiments running at the same time. Starting late 2019 we opened our process and successfully leveraged it to rapidly build and launch MVPs for other startups.
