The hackathon was a chance to showcase the product-led way of working we introduced to bol last year, while working on a topic that is important to all of us; Sustainability! In cross-functional teams (with engineers, PMs, Designers, Analysts and business representatives) the participants could focus for 4 days on the topic of sustainability, and how we as bol could contribute even more to sustainable shopping. After 4 days the teams presented their problems-to-solve, customers* to solve the problem for and proposed solution to a jury including our CPO, CTO & CeCO, who all valued the work that was put in highly. Participants really loved working with people in different roles and from different departments, the fact that they could contribute to the bol purpose to accelerate sustainable consumption & (for some) getting to know the wonderful world of product-led working.
