What Zemtu does

Zemtu is an Austrian software company that develops a web-based carsharing and shared-mobility platform used by operators to run station-based, zone-based, and free-floating sharing services for cars, e-cars, vans, bicycles, e-bikes, cargo bikes, and scooters. Founded in 2015 in Vorarlberg, Austria, by Dominik Bartenstein, Philipp Metzler, and Roland Kainbacher — who had previously launched the caruso carsharing service in 2009 — Zemtu sells a unified 3-in-1 product consisting of a mobile app (iOS, Android, PWA) for end users, a desktop booking application for fleet managers, and an admin dashboard for operators, supplemented by REST and GraphQL APIs and white-label app distribution in the App Store and Google Play. The platform integrates with leading telematics and hardware vendors — INVERS CloudBoxx, Convadis C-Compact, Smartcar OEM APIs, I LOCK IT bike locks, and Fink Logger — enabling both hardware-attached and hardware-free (OEM-API-based) carsharing, with billing via Stripe (credit card, SEPA, Apple Pay, Google Pay) and on-premise data hosting in a secure Austrian data center.

The company operates a quote-based, multi-year SaaS subscription model supplemented by professional services for onboarding, customization, and pilot deployments, with no public pricing. Zemtu's customer base is concentrated in Europe (Austria, Germany, Switzerland, Liechtenstein, Czech Republic, Spain) with growing US presence, and spans public-sector carsharing operators, municipal utilities (Stadtwerke), corporate fleets, car dealers, bikesharing operators, and rural community programs. Distribution combines a sales-led direct motion (website demos, consultation, pilots, customization) with indirect lead flow from hardware partners who recommend Zemtu as their preferred software layer, and content marketing through detailed public-sector and enterprise success stories. The company remains privately held and founder-controlled, with no disclosed external funding and a team of approximately 17–20 people.
