About Us

We are a family company from Poland (Europe). We have been working on this project for more than two years. It is our dream to make efneo a global product. We are a group – father, his sister and his adult sons.

• Stefan Migaszewski – father, the inventor
• Bogusława Janowska – his sister, the investor
• Wiktor Migaszewski – I am focused on technical details and patent processing
• Fryderyk Migaszewski – I am a manager, my objective is to make efneo a profitable company

Our collaborators come from the best Polish Technical University of Warsaw and from metal processing industry. They bring the best technical expertise to the team. We have been working on this project for more than two years. At this moment:

• the invention is patent pending.
• we have a working prototype – it works smoothly and in line with all the assumptions. It’s partly built of plastic so it has only been tested under very limited load.

Follow our progress on Facebook and Twitter! Subscribe to the Product Launch Alert! Comment on our posts.  We are looking for manufacturers of some metal parts. If you are a manufacturer or know the industry you can find the details with technical drawings here.
