What they’re building

HousApp helps real estate offices handle enquiries, manage their inbox and schedule property viewings. The platform aims to reduce administrative work so agents can spend more time with buyers, sellers and leads.

Its software connects customer communication with the everyday workflow of an agency. That gives teams one place to follow up instead of coordinating appointments and messages manually.

HousApp raised €4.3 million in a seed round backed by Arches Capital, Antler and angel investors. The funding supports product development, engineering and expansion of its platform for real estate agencies.
