Trusted and loved by customers worldwide


“We can make calls at about 5x the rate that we would with a manual dialer, getting through a list of 100 calls in just over an hour. This has been a huge capacity saver in our organization.”

Amanda Destefano, Leadership Organizer, United Workers

“I really love your team. You are just super responsive and super friendly and nothing’s too difficult! It’s been a really good experience.”

Shaun Murray, Senior Organizer, GetUp

“A lot of our folks are volunteers, a lot of them are retired, they are often anxious with technology and they were able to use CallHub easily. It’s empowering for volunteers who don’t see themselves as very tech savvy to be able to pick up a new piece of software and a new program and just use it, so that was great.”

Celine Trojand, Digital Organizer, Organizing for Change

“I love this product. It’s so easy to use with a very clean user interface. The price is the most economical I’ve seen in the industry and last but not least is the wonderful customer support. They answer all questions very quick.”

Ronald Hart, Marketing, The Cloud Marketers

“Solid dialer, responsive support, and awesome CRM integrations!”

Django Merope Synge, Campaigns Director, GetUp

“CallHub made my marketing program easy and also affordable. I love the dialer, the SMS marketing program and the voice broadcasts. The CallHub team is doing a wonderful job!”

Wendy Mathis, Global Quest Services

CallHub has become my go-to platform for affordable phone canvassing campaigns, voice broadcasts and text message blasts. In particular, text message blasts are the single most useful tool for volunteer mobilization that I have used in recent years.

Jordan Bober, Director of Development and Election Readiness, Green Party of Prince Edward Island
