From LBS to 7m trees: TreeApp founders hit major climate milestone
Founded on Earth Day 2020 by LBS alumni, TreeApp has grown from a classroom-inspired idea into a Europe-wide climate tech success story
What began as a conversation between London Business School classmates has quietly grown into one of Europe’s most ambitious reforestation platforms.
TreeApp, founded by LBS alumni Jules Buker and Godefroy Harito, has announced a major milestone in its 2026 Impact Report: more than 7m trees planted globally. Launched deliberately on Earth Day 2020, the trio set out with a deceptively simple idea, democratise environmental impact by letting anyone plant trees for free, every day, with the activity funded through advertising partnerships.
The concept, born during their time at LBS, was rooted in a shared frustration: climate action often felt distant, expensive, or inaccessible. Their solution was to turn it into something frictionless and habitual—an app that converts attention into measurable reforestation.
Since then, that idea has scaled far beyond its early prototype.
Today, TreeApp supports over 450 native and non-invasive tree species and has generated more than 70,000 workdays for local communities and farmers involved in planting and stewardship projects. Its footprint now spans Europe, with active reforestation sites in Greece, Spain, France, and Germany, alongside more than 100 UK locations.
The platform itself has expanded into over 30 European countries, evolving into a widely used climate engagement tool for both individuals and brands seeking verifiable environmental impact.
The founders, now Forbes 30 Under 30 honourees, trace much of the company’s trajectory back to their time at London Business School, where exposure to entrepreneurship, systems thinking, and impact investing helped shape the business model that underpins TreeApp today.
The 2026 Impact Report also highlights how the company’s projects are contributing to broader ecological and social outcomes, including biodiversity restoration, soil regeneration, and alignment with the UN Sustainable Development Goals. Alongside the data, it foregrounds stories from landowners, farmers, and planting teams whose livelihoods are increasingly tied to long-term environmental regeneration.
Seven million trees marks a symbolic and operational milestone, but for TreeApp’s founders, it is also a proof point. What started as an LBS-born idea to make climate action effortless has become a scaled infrastructure for everyday environmental participation, with the ambition clearly still compounding.
