Fill your team shirt with sponsors

How it works

From idea to fully sponsored shirt in three steps.

1

Create your campaign

Add the player name, story, shirt colors and number range. Share the link with your network.

2

Supporters claim numbers

Each number has a price (number = amount). Sponsors pick a number and their name appears on the shirt.

3

Shirt fills up

Watch the shirt fill in real time. Every claim triggers a share, bringing in the next sponsor.

What it looks like

Sponsor names printed on the back of the shirt. Every number tells a story.

Frequently asked questions

Yes, completely free. No account needed, no hidden costs, no commission. We built this to help sports teams.

Payment happens outside the tool. When someone claims a number, you receive a notification with their details. You arrange payment directly (bank transfer, cash, or however you prefer).

You choose the shirt color, text color, and number range (e.g. 1 to 20 or 10 to 99). You can also optionally skip number 13.

The campaign page stays visible but no new numbers can be claimed. You keep access to the manage page to track payments.

Absolutely! The tool is optimized for WhatsApp sharing. After claiming a number, sponsors get a pre-written WhatsApp message with a link to bring in the next sponsor.

What organizers say

We raised the full amount in just 3 days. The WhatsApp sharing after each claim really snowballed. Friends of friends started sponsoring numbers.

Team parent, U14 softball

The visual shirt filling up was a game-changer. Once people saw their name on the shirt, they started sharing it everywhere. We went from 2 sponsors to 18 in one weekend.

Marco van den Berg

Coach, U16 baseball

No accounts, no payment hassle, just pick a number and done. My daughter set it up herself and had the whole team sponsored within a week.
