Commsor enables companies to activate their network (advisors, investors, partners, customers, influencers, etc) to drive revenue. Effectively we do that three ways: 1. Add a warm intro check for the sales teams. Before they make that cold call, we help them check if someone can open that door for them. 2. Connect your prospects with customers they already know, but more importantly already trust. 3. Enable you to build proper B2B referral programs. None of that B2C "click my link and I get a referral cut" stuff Did you know our logo is a Brontosaurus and that they were so large that scientists still arent fully sure how they would have moved under their own weight? 🦕
