"We started working with Whistle in February 2022. It was very evident that Whistle has plenty of experience at onboarding new customers. The process was professional, efficient and comprehensive. This was one of the main reasons we decided to partner with Whistle – we wanted to avoid a long learning curve and onboarding process, and Whistle definitely delivered."

“They took the time to really get to know our product, target markets and internal procedures, and were able to work around our current flow seamlessly. The team is enthusiastic, personable and have been incredibly supportive with great advice and regular check-ins for strategy and practice, which has been incredibly helpful.”

"They helped set up a whole new SDR function for us which was massive. Their team members were bright, intelligent, and hard working as well. Leads responded to them nicely. They helped schedule 800+ sessions."

“The girls on our Whistle team crush their goals every day, every month. They have amazing attitudes and willingness to be part of our team. Love Whistle!!!! "

"We selected Whistle because of their time-zone availability and proven success in past work. They helped us to increase demos booked and decrease no-show rates. Initially, we were looking to run through a backlog of thousands of warm leads that we didn't have the manpower to get to. Now, Whistle helps us stay on top of the large number of new inbound leads we have starting trials."

"It's been really great to work with the Whistle team. With no SDR in place we needed a quick way to start cold-calling prospects and Whistle were able to step in and deliver in a super quick way. I'd highly recommend Whistle for all your outsourced SDR needs."

"We view Whistle as an inherent part of the Setpoint team, together we join forces to unfold target markets and niche audiences. The team has demonstrated the agility to pivot as needed time and time again, with creativity and much enthusiasm. We recommend working with them."

“Whistle has delivered a high volume of leads, as well as some outstanding creative content for sequences and professional service that we can rely on. We trust the team to do a good job and haven’t been disappointed. I highly recommend them.”
