TESTIMONIALS

Winning Stories from Real Campaigns

When other platforms were struggling, CallHub was a trusted partner who could easily scale up quickly when needed… from texting 5 people to calling 5 million, we could trust CallHub.

John Robinson

Campaign Manager, Bernie

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

A lot of our folks are volunteers, a lot of them are retired, they are often anxious with technology … It’s empowering for volunteers who don’t see themselves as very tech-savvy to be able to pick [CallHub] and a new program and just use it!”

Celine Trojand

Organizer, Organizing for Change
