Koncert Review (2026)

Every plan card on Koncert's pricing page has a button reading Get Pricing where the price would be. Four plans, no figures, and a footer that says contact us for pricing.

The HTML tells a different story. Fetch the page and there is a five-column comparison table carrying the numbers 6, 7, 29, 79 and 99, one for each dialer product.

So there are two problems here and only one of them is Koncert's. The vendor hides a table of undenominated integers. This site read one of those integers — the 79 — and published it as Koncert's seat price. It has been removed rather than corrected, because a number the vendor does not show and has never attached a currency to is not a price.

That is the third time this week a figure in this directory turned out to have come from adjacent text rather than from a vendor's stated rate. Air.ai's $0.11 came from competitors' articles. Woodpecker's $29 appears to have come from prose comparing somebody else's per-seat charge. This one came from a hidden table.

The only dollar figures Koncert publishes

They are on a landing page you cannot reach from the navigation, which is not in Koncert's 619-URL sitemap, and whose only inbound link is a banner image inside a blog post from November 2024.

Take the discount at its word and the implied list price of the AI Flow Dialer is $150 a seat a month. The hidden table's column for that same product reads 79.

The smallest purchase Koncert publishes is therefore three seats for three months at $75, which is $675 — after which the rate, on its own arithmetic, doubles.

The consumable, and the floor, both hidden with the price

That landing page is also the only place Koncert prices a caller ID: a dollar each. The caller ID page itself describes buying numbers a few clicks away, a Twilio integration that provisions them, and a heat map that monitors reputation and rotates anything approaching a spam label — and gives no allowance and no rate.

Rotation volume is therefore set by Koncert's detection rather than by you, and whether a replacement number bills at a dollar is not stated. For comparison, Orum publishes five caller IDs a month on its lower plan and ten per user on its upper one, and Salesfinity bundles ten a seat at no charge.

The three-user minimum is on that page too, scoped to the offer. The pricing page states no minimum, and an archived version from 2024 said the opposite in spirit: it did not matter whether you had five sellers or five thousand.

A burst dialer with no word for a dropped call

Koncert's parallel dialer runs four lines by default and five on the top tier. The extra line is the only thing separating the two multi-line plans, so a parallel line is the paywalled unit.

The string abandon appears nowhere across its 619 sitemap URLs. Its TCPA page is entirely about whether its dialers meet the definition of an automatic telephone dialing system, which is a different question altogether. Its FAQ raises compliance only as something for the buyer to take to their lawyer.

The vendor does discuss abandonment once, in a glossary entry about predictive dialers, a category it positions itself against. There it calls call abandonment the most significant challenge of dialing more numbers than there are available agents, and notes that regulators limit the permissible rate. It never names the 3% cap, and never says whether its own four-to-five-line dialer sits inside the same rule.

Koncert's position is that its dialers are human-initiated and not robo-dialers, which is a genuine distinction and not the one that governs abandoned calls. A buyer carrying that obligation needs a count, and the product does not appear to produce one: its call-status list runs to eight values (ringing, listening, answered, completed, no answer, failed, busy, cancelled) and cancelled means a call a human stopped before it connected.

How many dialers is it

Five, according to the navigation menu on the pricing page. Four, according to a second navigation block in the same HTML. Four plans across two dialers, according to the visible cards. Five columns, according to the hidden table. Three, according to the compliance page. And the dialers page renames one of them.

None of that changes what the product does. It does mean nobody at the company is reading the pages against each other, which is the same conclusion the pricing suggests. The live FAQ page still carries an undeleted placeholder heading and a paragraph of filler text.

What the newest product tells you about the meter

Koncert Phone launched four days before this review and is the clearest statement of the pricing model on the site: volume-based, no per-minute fees, unlimited outbound minutes, subject to a fair and reasonable use policy that is named on the plan card and published nowhere.

That is the Salesfinity shape, where unlimited turned out to mean ten thousand dials a month in the contract, except that Koncert publishes no contract at all. Its terms of use is a website document with no subscription, renewal or cancellation language, and no master agreement or order form appears anywhere on the site.

Of nine results for its pricing query, two are Koncert's own and two are competitors. Four are aggregators, and all four decline to answer: one prints pricing available on request, one says no plans are listed, one says details are available from the vendor. The highest-ranking page that tabulates Koncert's plans is a competitor's, and its price row reads custom pricing in every column.

Demo, quote, and a sales process. There is no checkout, no published trial, and the words free trial are commented out of the live HTML on the one page that has a price.

• Ask what 6, 7, 29, 79 and 99 mean. They are in the page you were sent and the vendor has hidden them; whatever the answer is, it is worth hearing.
• Ask for the regular price of the AI Flow Dialer, since the only published figure describes itself as half of it.
• Get the caller ID allowance and the replacement rate in writing. A dollar a number is published once, on a page you were not meant to find, and rotation volume is the vendor's decision rather than yours.
• Ask how abandoned calls are counted and capped. The product runs four lines by default and its call-status list has no name for the event.
• Ask for the Fair and Reasonable Use Policy that bounds the unlimited minutes on Koncert Phone. It is named on the plan card and published nowhere.
• Get a contract term. None is published, and the site carries no master agreement at all.

There is nothing to reproduce, so this section is what to extract and what to be careful of.

Careful of: any figure quoted for Koncert that traces to the hidden table. Those five integers are the most likely source of every per-seat number circulating for this vendor, including the one this site published, and the vendor has attached no currency to them in any version of the page going back to April 2025.

Extract: the regular seat price for each of the two dialers, the caller ID allowance and replacement rate, the contract term, and the fair-use ceiling on the phone product. Four numbers, none published, all of which decide the bill.

And price the add-ons separately. Koncert Phone, the AI voice agent, the pitch tool, the cadence product and waterfall enrichment are five distinct SKUs with no price on any of them. Enrichment at least states its meter, that you pay only when a net-new phone number is found, without ever stating what a found number costs.
