Crowdfunding with Painted Rocks

A child paints a bright orange rock with a heart on it. She writes its unique web address on the back — ROXGEO.COM/ABC123 — hides it in the local park, and walks away smiling. Two days later, a stranger finds it, visits the page, and donates to her classmate’s medical fund. That’s the power of a painted rock with a purpose.

How It Works

2

Paint & Link Your Rocks

Paint eye-catching rocks and register each one in RoxGeo — you’ll get a unique address (ROXGEO.COM/ABC123) and a secret PIN. Write the address on the rock and link your campaign, moneybox, or tracking link.

Hide & Watch Donations Grow

Hide rocks in parks, trails, and public spaces. When someone finds your rock and visits ROXGEO.COM/ABC123, they discover the story behind it — and can donate with one tap.

Who Is This For?

Anyone with a paintbrush and a cause can start. Here are a few ideas:

Teachers & Schools

A class project that combines art, geography, and empathy. Students paint rocks for a classmate in need or a school charity.

Parents & Families

A weekend activity that teaches children the joy of giving. Paint rocks together for a neighbor or local cause.

Community Groups & NGOs

Scout troops, youth clubs, church groups — any community can paint and hide rocks to raise awareness and funds.

Content Creators

Launch a rock painting challenge on social media. The treasure hunt format is naturally engaging and shareable.

Sports Teams & Clubs

Raise money for equipment, a tournament trip, or a teammate in need. Each member paints and hides rocks in the neighborhood.

Preschools & Kindergartens

Little hands, big hearts. Toddlers paint simple rocks with teachers, learning about sharing and helping others through play.

Senior & Care Homes

A meaningful intergenerational activity. Residents paint rocks for a local cause, connecting with the community beyond their walls.

Event Organizers

Add a painted rock hunt to festivals, fairs, or charity runs. Attendees find rocks that link to the event’s fundraising campaign.

Campaign Ideas

Not sure what to fundraise for? Here are real scenarios where painted rocks make a difference:

Help a Classmate

A child needs medical treatment or family support. The class paints rocks linking to the campaign — donations follow as rocks spread through the community.

Animal Shelter Support

Paint rocks with animal faces and hide them near parks. Finders discover the shelter’s story and can donate food, supplies, or money.

Community Playground

Kids paint rocks and hide them around the neighborhood. Each one links to a campaign for a new playground, park bench, or community garden.

Environmental Project

Raise funds for tree planting, beach cleanups, or wildlife conservation. Nature-themed rocks spread eco-awareness with every find.

School Trip or Camp Fund

Students paint rocks to raise money for a class trip, summer camp, or exchange program. Each rock carries the story of the adventure ahead.

Birthday or Memorial Fundraiser

Instead of gifts, ask friends to find painted rocks and donate. A beautiful way to celebrate a birthday or honor someone’s memory.

Support Someone Else’s Campaign with a Moneybox

A moneybox (skarbonka) lets you create a secondary collection linked to an existing campaign on 4fund.com. Instead of starting your own fundraiser, you support someone else’s cause by collecting donations separately. Perfect for schools or groups that want to contribute to a larger campaign. Learn more about moneyboxes.

Track Per-Rock Impact with Tracking Links

Tracking links (/z/ URLs) are unique promotional links that redirect to your campaign. Each link tracks clicks and donations separately, so you can see exactly how much impact each painted rock generates. Create a different tracking link for every rock and monitor real-time stats directly in the RoxGeo app. Learn more about tracking links.

Your Rock, Your Mission

You don’t need a school or a group. Any creator can link a single rock to a cause they believe in:

1 Create a free campaign on 4fund.com for your chosen cause.
2 Paint and register your rock in the RoxGeo app. You’ll get a unique address (ROXGEO.COM/ABC123) and a secret PIN.
3 Enable "Support a Cause" in the rock’s settings and paste your campaign link, moneybox link, or tracking link.
4 Write the rock’s web address (ROXGEO.COM/ABC123) clearly on the back. The PIN stays secret — only the finder uses it to confirm the discovery.
5 Every finder visits the address, sees the campaign, and can support it with one tap.

Best Practices

Paint bright, eye-catching rocks. Use weather-resistant sealant so they last outdoors.
Write the rock’s unique address (ROXGEO.COM/ABC123) clearly on each rock. You can also add #ROXABC123 for social media.
Hide rocks in high-traffic areas: parks, playgrounds, bus stops, and near schools.
Share photos on social media before hiding to build anticipation.
Update your campaign regularly with photos and stories to show impact.
Use tracking links (/z/ URLs) from 4fund.com or zrzutka.pl for each rock to measure per-rock impact. You can view click and donation stats directly in the RoxGeo app.

Frequently Asked Questions

Does it cost anything to start a campaign?

No. Both RoxGeo and 4fund.com are completely free for organizers. There are no platform fees, setup costs, or hidden charges.

Can people from other countries donate?

Yes! 4fund.com supports all major European languages and payment methods. Your rocks can cross borders, and donors from any country can contribute.

How do finders know about the campaign?

Each rock has a unique web address written on it (e.g. ROXGEO.COM/ABC123). The finder simply visits that page in their browser and sees the rock’s profile with photos, travel history, and the campaign link. One tap takes them to the fundraising page.

Is this safe for children?

Absolutely. Children paint under adult supervision. The fundraising link is reviewed by a teacher or parent. No personal data appears on the rocks. RoxGeo is designed with child safety as a core principle.

What if my rocks travel far away?

That’s the magic! The farther they travel, the more people discover your cause. Rocks that cross cities or countries bring your campaign to entirely new audiences.

What happens when someone finds my fundraiser rock?

The finder visits the address written on the rock (e.g. ROXGEO.COM/ABC123). They see the rock’s travel history and your campaign link. They can react with an emoji, mark the find with a secret PIN, and donate to the cause — all without downloading the app. To claim the rock and continue its journey, they can download RoxGeo and pick it up with GPS verification.

What is a moneybox (skarbonka)?

A moneybox is a secondary collection feature on 4fund.com / zrzutka.pl. It lets you create your own collection linked to someone else’s existing campaign. Donations go to the same cause, but you can track how much your group (school, class, community) contributed separately. It’s perfect when you want to support someone’s campaign without creating a new one. Learn more about moneyboxes.

What is a tracking link and why should I use one?

A tracking link is a special promotional URL (with /z/ in the path) that redirects to your campaign. Each tracking link tracks clicks and donations independently, letting you measure the impact of each individual rock. Create a unique tracking link for every rock you paint, paste it in the RoxGeo app, and monitor real-time stats to see which rocks generate the most engagement. Learn more about tracking links.
