Notes from the founder: The platform was originally meant to help businesses with their sales outreach and marketing. While businesses still continued to use us, I found a better market fit for CallHub with political campaigns and advocacy groups. Now in 2017, we have more than 700 customers who reach people in 200+ countries using CallHub.
