Homeday

Homeday is a German proptech real estate brokerage founded in 2015 and headquartered in Berlin, combining a nationwide network of local partner brokers with digital tools to help owners sell, buyers purchase, and both finance residential property across Germany. Its consumer products include free online and in-person property valuation, full-service sales brokerage, buyer representation, mortgage and financing brokerage through partner banks, and the Preisatlas transparent real estate price map for Germany. Homeday is backed by 500 Global and other investors. The company runs an active engineering organization on GitHub (homeday-de) publishing internal tooling, a Vue component library, design assets, and Ruby clients for third-party real estate APIs (ImmobilienScout24, onOffice), but does not currently publish a first-party public developer API or OpenAPI specification. This profile was added to the API Evangelist network as a venture-portfolio lead and enriched with identity, link-property, and domain-security signals.

Homeday is profiled on the APIs.io network. Tagged areas include Company, Real-Estate, PropTech, Germany, and Brokerage.

Homeday’s developer surface includes engineering blog, support, and 5 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data regime (on an ambiguous tag, where no other regime matched), so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/.
