Customer Success Manager Mid-Market (51-1000 emp.) 7/10/2026 "Highly Efficient Calling Solution with Excellent Support" 5/5 What do you like best about Koncert? I find the AI parallel dialer and flow dialer functions in Koncert very helpful as they have generated over 100 appointments for us in the past six months. I also appreciate the clean caller ID which boosts our connectivity rates. The team at Koncert is really helpful and quick to respond. The platform itself is robust with minimal downtime, and the connectivity is top-notch, enabling us to have conversations on nearly every fourth call. I also like how the user management is flawlessly easy to use. The app is self-explanatory, making adoption quick and straightforward. The setup was easy, and the support from the team was crucial for getting us started smoothly. Review collected by and hosted on G2.com. What do you dislike about Koncert? The only thing that would make it better for us but not a deal breaker is the list deletion option. As of now there is no way to delete a list once it is uploaded to the system. And this feature would greatly help if you are calling multiple campaigns but your ICP is crossed over from one campaign to the other. The fix for this can be either having the option to delete the list entirely or have the data uploaded scoped to a campaign. Review collected by and hosted on G2.com.
