There are more ways than one to look up prospective business partners, but (as often) I think that a direct way works best. And I believe that resorting to a site such as Sumsale is as direct an approach as it can be.
In general terms, the site is made up of listings that span the whole world, and that come from businesses that are looking for more exposure/new opportunities. If you are looking for local, regional, national or international business partners this site is a good port of call. Some of the territories that are covered include not only the United States, Canada and the United Kingdom but also territories such as India and China.
Still, it seems to me that the ones living in the US are getting the best deal since the main page is broken down in the different States and their main cities. The latest ads can be seen in each and every case, and you can also visualize the ones that have had the more comments.
The actual business categories are as wide-ranging as it should be, with consumer services and consumer goods being listed alongside financial services and general industrial equipment.
