The Problem

No one scores cities
the way we score companies.

Credit ratings, ESG scores, and risk indices exist for every public company. Cities, where 4.4 billion people live, have nothing comparable.

$$$
Expensive & Outdated

McKinsey charges six figures. The EIU (a global liveability index) covers 173 cities once per year at $1,500+ each. By publication, the data is months old.

Raw & Unstructured

GDELT (a public database monitoring 380,000+ outlets) provides raw event data but no scoring, no deduplication, no intelligence layer.

geo-centric APIs
Entity, Not Geo

Brandwatch (a social listening platform) tracks brands, not places. ZenCity (a civic engagement tool) works one city at a time for government clients only.

BRANDWATCH / ZENCITY
Across industries, decisions worth billions depend on understanding how cities are performing. Yet there is no standardized, programmatic way to assess a city's conditions.

Signals of adjacent demand: Numbeo (a crowdsourced cost-of-living database) sells API access at $100-500/month despite unreliable data. Teleport raised $2.55M from a16z for a similar vision before being acquired in 2017. Developers on GitHub actively build city tools using these imperfect sources.

Social Responsibility

Built for public good

The free dashboard is not a marketing funnel. It is the product's identity.

Civic Transparency

Free public dashboard lets anyone explore city conditions using data from 380,000+ independent sources.

NGO & Academic Access

Free API access for registered non-commercial users. Target: 3 NGO or academic pilot users by Month 4.

Transparent Methodology

Like Moody's and S&P, we publish our methodology. The value is in the pipeline, not the formula.

Open & Ethical

No personally identifiable information collected. GDPR-compliant data pipeline. Source credibility is transparent, not hidden.

The free dashboard is not marketing. It is core to the product's mission of civic transparency.
