One Challenge.
Endless branches.
Create a challenge website, share it with a few friends, and watch every person who passes it on become a new branch of your tree.
Start Your ChallengeHow It Works
Every person who takes part gets their own link, so the challenge keeps spreading without you having to push it.
Create your challenge
Name it, say what people have to do, and pick what they share when they take part.
Share it with friends
Send your challenge link by text, email or social. No account needed to open it.
They take part
They add a photo and a few words, enter a name and email, and they are in — in about two minutes.
The tree grows
Each new participant gets their own link and joins the tree underneath whoever invited them.
The tree is the whole point
Every participant is a branch, and every branch is proof that one person passed it on.
See every branch
Explore the whole movement from the first participant down to the newest one, however deep it goes.
See who invited who
Click anyone to see what they shared, who brought them in, and how far their own branch reaches.
Watch it grow live
New joins appear as they happen, with leaderboards for the people spreading it furthest.
What will you challenge people to do?
Rescue Pets
Share adoption stories and before-and-after photos, and get more animals a second chance.
Fitness
Runs, step counts, cold plunges — anything people can do and then dare a friend to match.
Acts of kindness
Pay it forward, one good deed at a time, and let each one invite the next three.
Environment
Beach clean-ups, tree planting, plastic-free weeks — with before-and-after proof.
Schools & Teams
Class challenges, spirit weeks and team fundraisers that spread through families.
Anything else
Start from a blank challenge and decide exactly what people share when they take part.
