The Challenge
The problem
Finding reliable contractors for housing and construction needs in Switzerland was fragmented and hard to trust. Individuals and businesses lacked a single, trustworthy place to discover local contractors, compare them, reach out, and see real feedback from other customers. HausBauCheck needed a marketplace that made discovery effortless and built trust into the housing community.
The Solution
What we built
A1 Digital designed and built a comprehensive marketplace — a mobile app and companion website — that connects people with contractors across the housing market. Using a single Flutter codebase for both Android and iOS (with a Laravel backend), the team delivered a seamless, consistent experience across platforms while keeping build and maintenance efficient. The result is an MVP engineered to scale as the network grows.
