Stefan Mueller

Founder & Owner

The founder

One owner. Every decision.

Leenway is owner-operated by Stefan Mueller. What began with a single product idea has grown into a house of consumer brands — from indoor gardening and teleprompters to gourmet spices, pet products and industrial labelling — built and run hands-on rather than managed from a distance.

That operating background shapes how Leenway invests: no committees, no lengthy due-diligence theatre. Founders and sellers speak directly with the person who signs — and who will actually run the business afterwards.

“I only buy or build what I would be happy to run myself for the next ten years.”
