Hiasynth Humanity — European demographics & market data

Hiasynth Humanity

Query humanity.

Find your customers, size your market and choose your next location anywhere in Europe, by asking your AI assistant in plain words. See who lives around each neighbourhood you're considering, how many people match your customer and the towns where they cluster most, and which channels reach them, from a whole country down to 1 km².

Every answer is computed from Hiasynth Humanity, a modelled population of all 522 million Europeans: each person in a household, each household in its neighbourhood, with about 700 attributes per person, from age and income to values, media habits and what the household spends. So you can combine anything, in any place.

Connect

Headless clients send an API key from hiasynth.co/app/mcp as Authorization: Bearer …:

Build it into your product

The same server is an API for your features and agents: size a market inside a CRM and show where to dig next, tie a marketing tool's personas to the actual population, or show the wallet size of any neighbourhood.

• Auth: OAuth 2.1 for user-facing apps, or a server-side API key from hiasynth.co/app/mcp (Authorization: Bearer …).
• Responses: structured JSON with the numbers already computed: counts, shares, lift against the local baseline, top places, and a confidence tier. Aggregates only, never individual records.
• Fine control: query_population takes a structured spec (group-by, filters, count/share/avg) for pipelines that need exact shapes.
• Any MCP client library works: the official SDKs, the Claude and OpenAI APIs' MCP connectors, LangChain, or plain JSON-RPC over HTTPS.
