It has been a great experience working with CallBox. The team is highly supportive and flexible in customising the campaigns as per your market and TG. Van has been excellent in supporting us at every stage.
Callbox offerings are the most competitive in the market and their account executives leave an indelible mark on prospects making sales a smooth transition for the internal sales team.
I spoke Van to about B2B lead generation for a SAAS product we are developing. His presentation was extremely clear an on point with what we want from a Lead gen partner. This really helps my business objective and my team to move forwards.
Callbox has been great to work with, their account and operations manager collaborates closely with us to overcome any challenges. They also take the initiative to optimize the processes, content, enablement and what it takes to get more leads coming in. They are an amazing team to work with! - Marketer at an SaaS company
