What is Koncert?
Koncert is a B2B sales engagement and dialing platform built to help sales teams have more high-quality conversations in less time. The platform combines AI-powered dialers, human-assisted dialing, multi-channel cadences, and sales coaching tools into a single environment that plugs directly into popular CRMs and sales engagement systems. By filtering out voicemails, bad numbers, and phone trees while automatically managing caller IDs and logging activity, Koncert lets reps focus their time on live conversations instead of manual dialing and administration.
The company traces its roots to ConnectLeader, a New Hampshire, based sales engagement vendor founded by Senraj Soundar and focused on inside sales productivity. ConnectLeader, founded in 2008, rebranded to Koncert in 2021 to reflect the evolution of its product from pure dialing to a broader multi-channel sales engagement and AI-driven platform. Today Koncert’s suite includes AI Parallel and AI Flow (power) dialers, an Agent-Assisted dialer, Click Dialer, Koncert Cadence for multi-channel outreach, AI PitchLab for real-time coaching, and Waterfall Data Enrichment for cleansing and enriching contact data.
Koncert differentiates itself in the dialer market with an emphasis on ultra-low latency call connections, automated local presence and caller ID health, and integrated coaching features like Remote Coach and Remote Salesfloor. The platform is SOC 2 Type II, GDPR, and TCPA-aligned, and integrates deeply with Salesforce and HubSpot alongside sales engagement tools such as Outreach, Salesloft, and Apollo.io. These integrations provide bi-directional sync so calls, emails, notes, and outcomes are captured automatically where sales teams already work.
Positioned primarily for B2B organizations running high-volume outbound motions, Koncert serves SDR/BDR teams, account executives, inside sales, and revenue leaders who need to scale outbound prospecting without adding headcount. The company has been repeatedly recognized in G2 Grid Reports as a high performer and momentum leader in categories such as Auto Dialer, Sales Engagement, and Sales Coaching, and is increasingly compared against modern AI dialers like Orum and Nooks as well as broader sales engagement platforms like Salesloft and Outreach.

Who Koncert is for
A strong fit for
B2B organizations with dedicated outbound SDR/BDR or inside sales teams that need to dramatically increase daily dials, live conversations, and pipeline by automating dialing, improving connect rates with local presence, and coaching reps at scale.
Probably not for
Very small teams with low call volumes, businesses that primarily rely on inbound or chat-based sales, or organizations looking for a lightweight CRM rather than a specialized outbound dialing and sales engagement platform.
How Koncert compares
Within the dialer and sales engagement market, Koncert positions itself between pure-play power dialers and full sales engagement suites. Compared with legacy auto-dialers or basic VoIP tools, Koncert offers a much richer set of capabilities: AI-powered multi-line dialing, automated local presence and caller ID health, virtual salesfloor functionality, and integrated conversation intelligence. This allows it to compete directly with modern AI dialers like Orum and Nooks on productivity while offering more built-in coaching and compliance features.
Against broader sales engagement platforms such as Salesloft and Outreach, Koncert’s strengths are its dialer depth, call quality, and outbound calling specialization. Those platforms often lead on email-centric workflows and ecosystem breadth, whereas Koncert excels at high-volume, phone-first outbound motions and real-time coaching. For teams that already rely on Outreach or Salesloft for sequencing, Koncert can act as the dialer backbone via its native integrations. For organizations whose primary bottleneck is live conversations rather than email automation, Koncert’s dialer-centric approach, ultra-low latency infrastructure, and caller ID management can make it a more effective choice than general-purpose engagement tools.
Tool research is the easy part. Someone still has to build the lists, write the copy, make the calls, and book the meetings.
