Ask HN: Lead-Gen agency for a software company?

There is a cool lead-gen agency in Germany that provides a list of the high-quality leads that need CRM / ERP software solutions. The lead-gen agency already pre-vetted these leads and sell them to the software companies. So they are high-quality leads that need a software solution.

Since I am looking for clients for my software company, I am wondering if there is something similar but for the UK or US market?

Thanks, Marko
