I would start by using some of the same techniques you used to grow your sales in the EU to enter the US market.

Producing consistent quality content on your website is essential. Along with a solid social media strategy.

From there once you develop a solid presence it will be very easy to reach out to more small distributors, centers, partners etc. and get them on board. Plus you if everything is done right you will have inbound leads wanting your product too.

Make sure your partners have a healthy margin and understand the demand for your product.

If you need any help along the way Im just a call away.
