Owner-managed and your partner since 1995.
who is an engineering company from Lübeck — founded on the conviction that good electronics only emerge when hardware, firmware and software are conceived together.
Our Values
Three convictions that guide our daily work and that our clients value in us.
Uncompromising Quality
Quality isn't a checkbox — it's an attitude. Our TÜV-certified QM system to ISO 9001 and ISO 27001 is the foundation, but our standard goes further. Every project benefits from the experience of over 500 that came before.
Partnership as Equals
We see ourselves not as a service provider but as a development partner. Our clients involve us in their product strategies for the long term, because we think along, ask the right questions and find the best solution together.
Technological Curiosity
We are passionate developers and keep developing ourselves, too. Through active technology scouting, we spot new trends early and bring innovation into your products.
The who Ingenieurgesellschaft mbH was founded over 30 years ago.
What began with electronics development on a LonWorks® basis is today a high-tech engineering service provider for tailor-made hardware, software and firmware solutions. We develop systems across the entire product lifecycle — from the idea through prototyping to series production, including maintenance, updates and further development.
