OUR STORY

Hamerly AG · Zuzwil SG · Construction software for construction companies in Switzerland, Germany and Austria

Built by builders. For builders.

Hamerly was not created in a startup office or a Silicon Valley coffee shop. It started with a real problem. We, Bianca Müller and Elaine Holl, worked on several projects ourselves and experienced firsthand how chaotic communication on construction sites can be. Tasks were sent through WhatsApp. Photos lived in private chats. Documentation was incomplete. And when mistakes happened, it suddenly mattered who said what and when. We quickly realized how easily a construction project can end up in a legal dispute simply because important information was lost or never documented properly. That experience led us to start Hamerly.

A platform built for real construction sites

From the beginning, our goal was simple. We wanted to build a product that works for everyone on a construction site. For site managers. For general contractors. For subcontractors and trades. A tool that brings communication, tasks and documentation into one place so projects run more smoothly and critical information never gets lost. With Hamerly, construction teams can organize their projects digitally, reduce mistakes and always understand what happened on site.

Built for Europe and the DACH region

The construction industry in Europe, especially in Germany, Austria and Switzerland, has strict requirements for documentation, privacy and accountability. Hamerly was built specifically with these requirements in mind. Our principles

  • GDPR compliant: Your data stays in Europe.
  • Full data ownership: Export your project data at any time.
  • Transparent documentation: Every task and communication is traceable.

Our mission

We believe construction projects should not fail because of poor communication. With Hamerly, we are building a platform that makes construction sites more structured, transparent and efficient. So construction teams can focus on what really matters. Building.
