They diverge on capability: Cognism covers Diamond Data, Koncert covers AI Parallel Dialer.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Cognism

United States coverage is behind ZoomInfo, and the gap shows most in mid-market American accounts where record density thins out.
The commercial model combines an annual platform fee, per-seat licences and credit allowances, so a quoted seat price consistently understates the total.
Diamond Data verified mobiles are a subset of the wider database rather than the whole of it, and the subset available for your target market should be tested before signing.
There is no free tier and no monthly rolling contract, so evaluating properly means committing to a year or relying on a short trial with limited data.
Coverage density varies sharply by country, with the United Kingdom strong and DACH and the Nordics noticeably thinner, which matters if your expansion market is the weak one.

Koncert

Pricing is not published; the pricing page shows placeholder numbers rather than real rates and directs you to sales, which makes it impossible to compare cost per seat against Orum or Nooks without entering a sales cycle.
Parallel dialling connects representatives so fast that they arrive on a live call with no time to recall prior context, and reviewers report this pushes reps onto a rigid script and degrades conversation quality even as dial volume rises.
Koncert supplies TCPA-supporting features but not legal cover, and parallel and agent-assisted dialling attract regulatory attention in several jurisdictions, so the compliance burden and any liability stay with your organisation.
Selling four dialler products rather than one means the capability you evaluated may not be the one you bought, and switching modes or mixing them across a team frequently involves renegotiating the contract.
The agent-assisted dialler bills for human labour rather than software seats, so its cost scales with call volume rather than headcount and can rise sharply during a campaign push in a way a per-seat budget does not anticipate.

Answered from the vendors’ own pages

Cognism: Can a European company use it lawfully?

It notifies contacts held in its EU and UK database and screens do-not-call registers, which supports a legitimate interest basis. The balancing test, record keeping and handling of objections remain your obligation, not the obligation of the vendor.

Koncert: What is Koncert previously called?

ConnectLeader. The company rebranded to Koncert while retaining the same dialler technology lineage.

Cognism: How does it compare with ZoomInfo on coverage?

ZoomInfo is stronger in the United States, Cognism is generally stronger on European mobile numbers. That, rather than feature lists, is what most head-to-head evaluations come down to.

Koncert: What is the agent-assisted dialler?

Human agents place calls and navigate gatekeepers, phone trees and receptionists, connecting your representative only when a live decision maker is on the line.

Cognism: Can we buy a single seat monthly?

No. Contracts are annual with a platform fee, which makes a genuine pilot harder than with credit-based self-serve vendors.

Koncert: Is pricing published?

No. The pricing page shows placeholder figures and directs visitors to contact sales for a quote scoped by dialler type and seat count.

Koncert: Is parallel dialling legally safe?

Koncert provides TCPA-supporting features and holds SOC 2 Type II and GDPR compliance, but the calling organisation remains responsible for regulatory compliance in each jurisdiction it dials into.
