€1

Why one euro?

Small enough to be simple. Universal enough to connect us.

The experiment is not about what one euro buys. It is about the scale of a shared choice—the same small action, repeated across borders.

  • One clear action
  • The same amount for every participant
  • A question anyone can share

The global goal

One billion is the horizon—not a guarantee.

The purpose is to observe how far a simple, voluntary idea can travel. There is no promised destination, only an open experiment shaped by each person who chooses to take part.

Clarity matters

Transparent by design.

01

Completely voluntary

Joining is always your choice. Share only if the idea genuinely interests you.

02

Not a charity

This is an independent social experiment. Your euro is not a charitable donation.

03

Not an investment

No profit, return, reward, prize, ownership, or guaranteed outcome is offered.

04

Visible participation

A participant counter is prepared for transparent public progress as the experiment develops.

Questions, answered

The clear version.

Is this a charity or fundraiser?+

No. The 1 Euro Global Experiment is an independent social experiment. Participation is voluntary, and contributions are not charitable donations.

Is my €1 an investment?+

No. It is not an investment, and there are no rewards, returns, profits, prizes, ownership rights, or guaranteed outcomes.

Why exactly one euro?+

One euro is deliberately small and consistent. The experiment explores what collective participation can look like when the individual action is simple.

What happens after I join?+

Stripe confirms your payment. Your participation becomes part of the total, and you can help the idea travel by sharing the experiment.

Is one billion participants guaranteed?+

No. One billion is the global question behind the experiment, not a promise or forecast. The outcome depends entirely on voluntary participation.
