What it is

A signal, not a sale.

Belief comes before money. Before pilots. Before contracts. It's the first thing — and it costs nothing.

Sign your name

Tell us who you are, where you're from, and which tier resonates with you. Two minutes, no money.

Share the proof

You get a Cittopian badge ID. Share it. Tag your home city's mayor. Forward to one municipal contact.

Watch the wall grow

Every signer joins the public Wall of Belief. As it grows, cities and institutions take notice. Word of mouth builds momentum.

Four ways to be a Cittopian

Pick the one that fits you.

There's no hierarchy of effort. A citizen who shares with their cousin's town council moves the needle as much as an institutional partner. We celebrate every level.

🌱
Tier 1

Cittopian

Anyone who believes in the urban climate transition. Citizens, students, climate-curious humans.

What we ask: Sign your name. Share the page once. That's it.
🤝
Tier 2

Cittopian Champion

Word-of-mouth amplifiers. People with a network, a city contact, a mailing list, a small audience.

What we ask: Sign + introduce one decision-maker (mayor's office, climate dept, NGO).
🏛️
Tier 3

Pilot City

Municipalities ready to be among the first 100. We work directly with you on onboarding + verification.

What we ask: Express municipal interest. We follow up with a 30-min discovery call.
🌍
Tier 4

Founding Institution

EU bodies, UN-Habitat, NGOs, academic networks, research consortia, urban planning bodies.

What we ask: Strategic conversation about programme alignment.

The Wall

Recent Cittopians.

A few of the people putting their name behind this. The wall grows in real time as more believers sign.

Why this matters

Belief moves cities.

Municipalities don't sign SaaS contracts on a whim. They sign when their staff have already heard the name. When a councillor's daughter mentions it. When a peer mayor says they're piloting too. That's where the Wall of Belief becomes power.

Word of mouth scales

Every signer has a network. Every network has a city employee. Belief travels through people, not ads.

Procurement validation

When we walk into a municipal procurement meeting, the Wall of Belief is the proof that we're not vapourware.

Roadmap alignment

What signers ask for shapes Phase 7+ priorities. The Wall is also our voice-of-customer feed before we have customers.

Two minutes. No money.
A lifetime of being a Cittopian.

The cities of tomorrow are listening. Show your belief.
