Technical co-founder & back-end developer 

About us

Treemendo enables customer and companies to plant and own forests. We address some of the biggest problems in afforestation & climate change by enabling users to purchase and plant trees, through a gamified planting and forest experience, via a mobile and web application.  Using different sensors we are able to recreate the forest for the users. With the funding of people we planted our first forest in 2019, and are aiming to plant 1 million trees in 2020.
