Doozer

What Doozer does

Doozer Real Estate Systems GmbH is a German PropTech company headquartered in Berlin that provides a cloud-based SaaS platform for digitizing vacancy apartment renovation management for professional property holders, housing companies, asset managers, and property managers. Founded as an engineering office in 2010 with formal platform launch in 2012 and digitization mission formalized in 2014, the company addresses a specific bottleneck in the German Wohnungswirtschaft: every second apartment requires renovation between tenant changes, often resulting in 5-month vacancy periods that cost housing companies significant rental income.

The core product is the Doozer SaaS Platform, comprising approximately 23 modules covering the full renovation lifecycle from apartment intake through configuration, service package selection, real-time cost calculation, craftsman selection and commissioning, multi-level approval workflows, change order and defect management, digital handover protocols, and central revision-secure document storage. The platform exposes a Standard-API at no additional cost for integration with ERP systems (including SAP), BI tools (Power BI, Tableau), and DMS systems, with ZUGFeRD-format invoice generation for German e-invoicing compliance. Hosting is in ISO 27001/27017/27018-certified EU data centers with GDPR-compliant processing on German servers.

Doozer operates a dual-tier revenue model: Doozer Business offers free platform access with a commission fee (described as in the Skonto/discount range) charged when a craftsman is commissioned through the platform, while Doozer Unlimited provides full subscription access at less than 1 Euro per residential unit per month for customers using their own framework contract partners. Go-to-market combines enterprise field sales targeting housing companies with approximately 3,500+ residential units through consultation calls, demos, and pilot programs, with self-service registration available at app.doozer.de. In June 2024, Doozer merged with Zig, the leading Dutch housing industry software provider (ERP, CRM, tenant portal, BI) serving 200+ organizations, in a transaction supported by Main Capital Partners, creating a combined European housing technology platform with 250+ employees and a customer base spanning LEG Immobilien, degewo, Adler, Hilfswerk-Siedlung, Noratis AG, ZBI Gruppe, and Pro Haus Plus.
