"Konsert’s Parallel Dialer, New UI, and AI Notes Supercharge Productivity"
5/5
What do you like best about Koncert?

The parallel dialer is amazing. I get through my work so much faster than I ever could with a single-line dialer. I absolutely love the new UI, and the AI note taker saves me a ton of time. Reporting is extremely important for us, and the number of features Konsert offers—especially the ability to drill down into micro reports—has been a real game changer for me. Review collected by and hosted on G2.com.

What do you dislike about Koncert?

I’ve been using Konsert for just over a year, and so far I have zero complaints. There have been a few minor glitches here and there, but whenever that happens I just log a ticket and Support typically has it fixed within a day or two. Review collected by and hosted on G2.com.

"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.

"AI-Powered Parallel Dialing That Connects to Humans Faster—Great Value"
5/5
What do you like best about Koncert?

AI powered Parallel dialing feature. Allows to augment a team of callers and connects to a human quicker. Price is very reasonable. Review collected by and hosted on G2.com.

What do you dislike about Koncert?

Interface analytics could be better designed. Would be helpful to know more data about the conversations and what was effective in meeting conversion. Another thing that Koncert can improve is sorting out calls that are call screeners. Review collected by and hosted on G2.com.

"Helpful overall, but Audio Lag is an issue"
2.5/5
What do you like best about Koncert?

can get through calls very quickly, if you have a low pickup rate Review collected by and hosted on G2.com.

What do you dislike about Koncert?

The audio lag kind of sucks. I've had audio issues with several prospects, where the lag has caused them to not hear me and they hang up. It's caused me to miss out on a handful of potential conversations with great leads Review collected by and hosted on G2.com.

"Superior CS and Support Teams"
5/5
What do you like best about Koncert?

The support by the CS team and the technical team itself is definitely the best I have received. They are patient in explaining things or helping to find workarounds when necessary, and the technical team turns things around in well under 24 hours in most cases, and I can vouch that they are responsive and helpful no matter the size of your business. Review collected by and hosted on G2.com.

What do you dislike about Koncert?

I can't say there is anything I dislike about Koncert, but I think they could just make the underlying technology a little more responsive. Review collected by and hosted on G2.com.

"Built for Real Sales Teams, Backed by Outstanding Customer Service"
5/5
What do you like best about Koncert?

I chose Koncert specifically because, to me, it is designed for actual sales people instead of telemarketers or call centers.

What I like best about Koncert is actually the people who run it though. They're customer service is insanely good. Review collected by and hosted on G2.com.

What do you dislike about Koncert?

The only dislike is some minor glitches that occur very rarely, but again, their customer service in resolution is fantastic! Review collected by and hosted on G2.com.

"Efficient Dialing with Room for Improvement"
3.5/5
What do you like best about Koncert?

I find the flow dialer super useful for making calls throughout my day. It's helpful for segmenting by calling mobile numbers, where I get the highest response rates. The integration with HubSpot is great for importing lists, and the automatic dialer and local presence streamline making calls and getting through lists efficiently. It's much faster than clicking to dial, and has a lot of crossover with HubSpot, which is very efficient for me. The setup was straightforward and simple. Review collected by and hosted on G2.com.

What do you dislike about Koncert?

I find that when I'm creating tasks and getting reminded of that, it hasn't worked super well on that front. Also, knowing when I have to wait for the phone tree to get to somebody's voicemail during the automated voicemail tracking is a bit unclear. I haven't gotten an answer on that, and I'm curious to know what's the case with that. Review collected by and hosted on G2.com.

"Revolutionized Our Outbound Calling with Efficiency"
5/5
What do you like best about Koncert?

I like the ability to change from dialing two at a time to five at a time, which is a huge help for making a lot of phone calls quickly. I also appreciate the ability to upload battle cards into the contacts and different leads list I'm dialing out of, so I have an idea of what to say, all ready and easily accessible. It actually just saves a lot of time and effort because with other tools like HubSpot or SalesLoft, you dial one by one and make 50 calls over three hours. But with Koncert, I can make hundreds of calls in one to two hours. The setup was pretty simple; Koncert helped walk us through getting everything integrated and imported in just a few hours. Review collected by and hosted on G2.com.

What do you dislike about Koncert?

Nothing comes to mind about a dislike. Its a great tool, don't have anything to complain about. Review collected by and hosted on G2.com.

Excellent support, responsive and helpful. Dialing tech is among the best in the market as well. Review collected by and hosted on G2.com.

What do you dislike about Koncert?

I don't like AI integration preventing user decision making: if we want to override the system it should put user choice ahead of best-practices. Review collected by and hosted on G2.com.
