Of the 264 AI SDR and voice agent tools in this directory, 114 publish no price at all. Not a starting price, not a per-seat figure, not a per-minute rate. A contact form.
That number on its own is a complaint, and complaints are cheap. The useful part is what happens when you split it by category, because the split is not random and it is not about company size.

Read the top and the bottom of that table together. Voice Infrastructure publishes a price 86% of the time. Inbound Qualification publishes one 11% of the time. These are the same technology sold to different people.
Infrastructure sells to an engineer who is going to build a cost model before committing, so a published rate card is a competitive advantage. Deepgram, Cartesia and Twilio all publish to four decimal places, because the buyer is going to multiply. The application layer sells to a VP who will be shown a figure inside a deck, in a meeting, after a discovery call that establishes what they can afford. A rate card would interfere with that.
Scheduling is the clean counter-example at the bottom of the table. All five tools publish, because scheduling is a commodity bought by an individual with a card, and a form would simply lose the sale to Calendly.
How this was counted
A tool counts as publishing no price when none of three fields could be filled from its own pages: a monthly entry price, a per-seat rate, or a per-minute rate. Free tiers do not count as a price, because a free tier prices nothing that a growing team will actually buy.
Prices were read first-hand off each vendor's own pricing page, never from an aggregator or a comparison post. 150 of the 264 records carry the date they were verified, all in 2026. The remaining records are either free-tier-only rows or vendors we cannot reach, which is its own finding: nine of them return a firewall challenge or disallow our crawler outright, and one serves rupee pricing to this machine with no dollar tier visible anywhere.
108 will not quote without a call
A slightly different count, and a more expensive one for a buyer. 108 of 264 have no self-serve path at all: no signup, no checkout, no trial you can start without talking to somebody.
The cost of that is not the meeting. It is that a buyer cannot build a shortlist without booking six calls, so the shortlist gets built from whoever answered fastest. On r/sales a buyer described being unable to do even that: “I need ballpark pricing, calling their reps is not an option without me getting in trouble”, because their employer forbids contact with vendors outside procurement. The only numeric answer that thread received was removed by moderators as self-promotion.
Publishing a price and publishing a meter are different questions
The count above is generous, because it treats any number as a price. Several vendors publish a figure that cannot be turned into a bill.
Lusha publishes both halves: a price, and the meter underneath it. A phone number costs five credits against one for an email, so a buyer can compute what their own motion will consume. Warmly publishes a price and never defines the credit it bills against. Cognism publishes neither and gates both behind a call. Only the first of those three lets anyone compute a unit cost before signing.
Twenty-one tools publish a per-minute rate, which sounds like the most transparent number on the site. It is usually the least. The advertised rate excludes speech recognition, the model, synthesis and telephony in varying combinations, and the excluded components are frequently larger than the rate itself. Millis advertises $0.02 and the components it excludes come to $0.0465, so the floor is 3.3 times the headline.
What we could not establish
Nine vendors could not be read at all: their sites return a firewall challenge to our crawler, or their robots file names it and disallows it. Those rows are recorded as unverified rather than assumed to be hiding something, because a bot policy is not a pricing policy and conflating the two would be exactly the kind of inference this page exists to argue against.
Check it yourself
Pick any five tools in Inbound Qualification from the directory and open their pricing pages. The claim here is falsifiable in about six minutes, and if the count is wrong we would rather hear it from you than not. Every row carries the date it was read, so a vendor that has since published a price can be corrected and re-dated rather than argued about.
