Money that stays local
Contribio is built on community wealth building. Points students earn are spent with partners near Penrhyn Road, Knights Park, Kingston Hill and Roehampton Vale, keeping value in Kingston, not leaking out to big platforms.
- Every partner is vetted before going live
- Your stats are calculated by the platform, so students trust them
- Run by a co-operative, not a corporation
Made for Kingston businesses
Quick answers for vendors
What does it cost?
Email sales@contribio.app and we'll talk you through it. Your spend bonus is optional, and you decide how much to put in.
How do I get paid?
Every Monday we add up what you're owed and pay it out. One point is worth 10p, so 50 points spent with you is £5.
What if my bonus pot runs out?
You'll get an alert to top up. Until you do, purchases that need a bonus are paused, so you're never on the hook for money you didn't put in.
Can anyone sign up?
Every partner is checked before going live, to keep students safe. Apply online and we'll be in touch.
