Your team has 10 days to walk.

(and their employees')

How does our 10-day challenge work?

Your employees just need to install the Treely app on their phones.

Over the 10-day challenge, the app tracks their steps (but not their data) and converts them into trees to be planted.

Every time a participant hits 15,000 steps, we plant a tree.
And every step counts (yes, even those to the coffee machine).

3 fantastic reasons to organise a Treely challenge

Strengthen team spirit

Thanks to team rankings and fun challenges, participants motivate each other and pull together to reach their goals.

Build a responsible company culture

By involving your staff in an ecological challenge and giving them the opportunity to plant trees, your ESG policy becomes participative and embodied.

Improve employee wellbeing

On average, Treely challenge participants walk 50% more than usual!

And 98% report feeling better after their challenge.


Participants say the Treely experience helped them get to know workmates they’d never chatted with before (whether they share the same office or work remotely).

How and where are the trees planted?

All the trees your team unlocks are put into the ground and monitored by the NGO Eden Reforestation Projects, who employs local communities in Madagascar.

Eden Reforestation Projects specialises in restoring devastated ecosystems.
