Questions we often get

Who does bon.do build software for?
We build apps, SaaS platforms, backends and connected devices for medtech, life science and healthcare companies, and for product companies that need the same discipline. We work with ISO 13485, MDR, IVDR, GxP and GDPR requirements. Bon.do is not ISO 13485 certified. We work inside our clients' ISO 13485 quality systems, and the regulatory responsibility stays with the client as manufacturer.
What does an app cost?
A focused MVP typically lands between DKK 30,000 and 150,000. Complex enterprise apps start from DKK 250,000. The free assessment gives you a written estimate for your product.
Do we own the code?
You do. All code, data and IP are yours from day one, built on open, well-documented tools, so you are never locked in to us.
