What Mietz does
Mietz GmbH is a Berlin-based PropTech company founded in May 2021 that operates a fully digitized, end-to-end rental platform connecting individual tenants with landlords, private property owners, brokers, and professional property managers across the DACH region. The platform is dual-sided: tenants use a free mobile app (iOS/Android) that enables swipe-based apartment discovery (modeled on a Tinder-style UX), one-time creation of a reusable application dossier, in-app landlord communication, and digital contract signing; landlords and property managers use a web-based SaaS platform ("Mietz for Business") that covers listing distribution, automated applicant qualification, broadcast messaging, calendar coordination, and contract execution.
The technology stack combines several proprietary modules. Mietz KI is an AI assistant that processes property images and structured data (address, rent, amenities) to generate listing/exposé texts incorporating micro- and macro-location information, translates tenant communications, drafts response suggestions, and evaluates applicant documents. Mietz Score is an AI-based tenant scoring engine that evaluates SCHUFA reports, pay slips, employment verification, and IDs to produce match scores between applicants and specific listings. The Digitaler Mietvertrag (QES) module delivers the first legally compliant in-app qualified electronic signature for German residential leases in the market, meeting §126 BGB Schriftformerfordernis and EU eIDAS requirements via AI-based video identification. Underlying infrastructure integrations include Nylas (calendar/OAuth), Firebase Cloud Messaging (push), and AWS SES (transactional email). The platform supports ERP/CRM/PM data import and cross-listing to major German portals.
Mietz monetizes through three primary streams: a transaction fee for each completed QES contract signing (pay-per-use, available standalone), a recurring B2B subscription for Mietz for Business (automated qualification, scoring, messaging), and a marketplace commission structure linking free tenants to paying landlords. The tenant app is fully free. The company holds a §34c GewO real estate broker license, is DSGVO-compliant, and reports all data stored in Germany. Go-to-market blends product-led growth on the tenant side with direct enterprise/B2B sales to property managers and participation in industry channels such as Aareon Connect. Named enterprise/mid-market customers include Cresco Real Estate, SMARTments business (NORD), IQ Bau, and Lempert & Zilch GmbH.

Mietz product offering
Product offeringCore offering
Mietz provides a fully digitized end-to-end rental platform connecting tenants and landlords through a mobile app and B2B web platform. The offering includes swipe-based apartment matching, AI-powered tenant scoring (Mietz Score), automated document verification, and legally compliant digital rental contract signing via Qualified Electronic Signature (QES). The platform replaces fragmented legacy workflows (email, phone, paper contracts) with a single integrated solution covering listing, applicant screening, communication, and contract signing.
Product overview
Mietz is a Berlin-based PropTech company offering the first fully digitized rental platform in Germany. The core offering consists of a dual-sided platform combining the Mietz App (mobile app for tenants) and the Mietz Vermieter-Plattform (web platform for landlords). These are supplemented by modular add-ons: the Digitaler Mietvertrag (QES e-signature solution), Mietz KI (AI assistant), and Mietz Score (tenant scoring). In March 2026, Mietz expanded into property sales as part of its strategy to become an all-in-one digital property platform. The platform targets urban rental markets with initial focus on Berlin, Hamburg, and Munich, serving both B2C (tenants) and B2B (property managers, landlords) segments.

Mietz competitors and assessment
Company assessmentBroad incumbents
- Zillow: US-based category-leading real estate platform with end-to-end rental and buying workflows. Comparable as a global blueprint for a digital property marketplace, though operating in a different regulatory environment.
- Immoscout24: Germany's largest real estate marketplace for both rentals and purchases, with broad consumer and B2B reach. Competes with Mietz for landlords' listing budgets but lacks Mietz's end-to-end QES signing and tenant scoring depth.
- Immowelt: Major German real estate portal for buying, renting, and evaluating properties. Comparable to Mietz as a rental discovery channel, though much broader and less specialized in workflow automation.
Emerging players
- Nestpick: European furnished and short-term rental marketplace for students and professionals. Comparable as a digital rental platform serving urban expats, though focused on medium-term furnished stays.
Direct peers
- Vermietet.de: German cloud-based property management software for landlords covering tenant communication, documents, and accounting. Closest direct peer to Mietz's B2B landlord platform offering.
- Homepilot (by Haufe): German property management SaaS targeting landlords and small property managers. Comparable to Mietz's B2B tools for tenant management, documents, and workflow automation.
- WG-Gesucht: Germany's leading apartment and shared-flat search platform serving students and young professionals. Directly comparable to Mietz's tenant-side marketplace for urban rental seekers.
- Doorbell (Türkiş & Partner): German digital property management platform offering tenant communication, document handling, and workflow tools for smaller landlords. Directly comparable to Mietz's landlord-facing workflow features.
Regional players
- McMakler: German digital real estate brokerage serving both buying and renting. Comparable as a digitally-enabled intermediary in the German market, though focused on sales and traditional brokerage.
Others
- Aareon: Germany's leading property management software vendor and Mietz's channel partner via Aareon Connect. Comparable as the dominant PM software ecosystem in DACH that Mietz integrates with and sells through.
