Broker Company... Not sure how many... Haven't counted. As in being an "employee" of a company or changing of titles... One. I did work with one other company this year as an employee. Their niche is account management software for the industry- completely unrelated to sales, brokering, or the work behind it.

Throughout "promoting" companies that have different niches, I've always had and have been Sendto. Keep in mind I work with Funders and promote products and confirm the credibility from the experience or relationship.
