Industrial start-up/scale-up

I am looking for an active participation in a start-up or scale-up within the technical (manufacturing) industry or manufacturing environment. It may involve both B2B and B2C propositions, as long as there is a physical, scalable product.

Criteria

• Phase: There must be a marketable product and demonstrable traction in the market. I don't get into the idea phase. Profitability is not yet a requirement, but there must be a view of a healthy business model.
• Size: A current revenue between €100,000 and €1,00,000.
• The Founder: I am looking for a founder who wants to stay on board and has the ambition to continue. You are not just looking for capital, but for a partner who brings "clout", knowledge and experience to realize the next phase of growth.
