Minimapper is a Finnish proptech startup building an AI-powered tool for making real estate photos understandable. Our product helps property portals, brokerages, and landlords to make listings easier to understand by showing exactly where each photo was taken within the property. Minimapper adds a small floor plan minimap with a viewing marker to listing photos, giving property seekers a clear spatial understanding of the spaces from the very beginning. Even though floor plans and photos are two of the most important assets in real estate marketing, today, this crucial connection is often missing from property listings. Interior photos can look attractive, but users often struggle to understand how the rooms connect, where a photo was taken, and how the property actually feels as a layout. According to a user survey by leading Finnish property portal Etuovi.com, 80 % struggle with spacial understanding without Minimapper, and two-thirds want to see Minimapper in listings, as it helps 87 % to understand the spaces easier. Minimapper is available in all HOAS properties in the Helsinki region, where they manage over 10 000 apartments. In 2025 alone, Minimapper helped over 650,000 students to find their next home more easily. We are now developing Minimapper into an automated AI API that can process property listings at scale. The goal is to enable major real estate portals and listing platforms to automatically add minimaps to property photos whenever a floor plan is available. We are looking for a backend-focused full-stack developer to help build the backend systems, cloud infrastructure and integrations around our AI pipeline. Experience with APIs, scalable backend architecture, Google Cloud, Dart & Flutter, visual AI, image processing or real estate technology is especially relevant. This opportunity is best suited for someone who is motivated by startup ownership and long-term upside. Initially, the compensation is expected to be primarily option-based, with the aim of building a well-funded, scalable company together. Minimapper is at an exciting stage: the core AI product exists, market discussions are active, and the path is clearing toward scalable portal integrations. We are eager to talk to you and find out what we could achieve together.
