Horizon Nua was the first spin-out enterprise created from the Horizon 2020-funded Connecting Nature project in 2017. The idea for the business came out of initial collaboration with three cities on new business models for nature based solutions. The cities asked for a guidebook capturing this process, we put one together, then other cities asked for it and started to translate it into their own language and from there it snowballed. In the first year alone there were more than 250 requests for guidebooks and workshops from more than 25 countries around the world. We stopped counting after that!
