Global data fails in Germany.
And another provider won't fix it.

The Mittelstand is barely on LinkedIn, and LinkedIn is where global data comes from. Germany's real data is public, official and in German. It rewards specialists, and we do nothing else.

Why we only do Germany

Three ways to enrich.

API Enrichment

Create a key and enrich from your own stack: one POST per lookup, JSON back.

CSV Enrichment

Upload a list in the dashboard, download the results file. No code required.

Waterfall Enrichment

Keep chaining global providers. Route German lookups through a specialist. Misses cost nothing.

From leads.csv to results.csv

Exactly as documented

Inputs, outputs, errors and rate limits are specified precisely. The reference is generated from the same definitions the API runs on, so it is always up to date.

Pay for results, not attempts

A found email or profile costs credits. A miss costs nothing. Plans start small and scale with your volume.
