What does it cost to outsource outbound?

Of the 101 companies here, 38 publish a price at all. Among those that do, the entry figure is usually a monthly retainer, and it often excludes a setup fee for domains and inboxes or needs a minimum term. Compare what the entry price buys, such as channels, volume and who writes the copy, before comparing two numbers.

Should I pay per meeting or pay a monthly retainer?

Paying per result moves the volume risk to the supplier and the definition risk to you. 16 companies here bill per meeting or per qualified lead, and 15 of them publish what counts as qualified. A retainer buys effort you can inspect; a per-meeting price buys an outcome someone else has defined, so read that definition before comparing prices.

Who owns the domains and inboxes an outbound supplier sets up?

It depends on the supplier, and most do not say. 49 of the 101 here publish nothing on it. Ask before signing whether the domains are registered to you, whether the inboxes sit in your workspace, and whether the lists and enrichment tables leave with you. If the answer is no, the pipeline stops when the contract does.

What counts as a qualified meeting?

Whatever the contract says, which is why it should be written down. Useful definitions name the buyer's title and company size, require the prospect to attend, and say what happens to no-shows. 38 of the 65 companies here that sell meetings or leads publish no definition at all.

What is GTM engineering, and how is it different from lead generation?

Lead generation sells an outcome, usually meetings, produced on the supplier's infrastructure. GTM engineering sells a system: the enrichment, scoring, signals and routing that decide who gets contacted and when, usually built in your own tools, often in Clay. Some companies sell both. The difference matters most when the engagement ends.

Are free pilot campaigns really free?

13 companies here offer a free pilot or test campaign. It costs no fee, but it is a sales process: the supplier chooses the segment, and a pilot run on its own infrastructure proves its system rather than building yours. Ask what you keep from the pilot if you do not continue.

Why do so few outbound companies publish a price?

63 of the 101 here publish no price. Part of that is genuine, because a build is scoped to your data and stack. Part of it is commercial, because a gated price means a call. Either way it is a fact about how a company sells, so this directory records it rather than estimating a figure.

Why are some companies listed first?

Frontal, ColdIQ and Arrel are clients or partners of busyless, and they are listed first for that reason. Their cards and pages say so. Everything else about their entries is the same as everyone else's: the same fields, read the same way, with silences and limitations recorded plainly.

The directory

GTM agency directory: who keeps the engine when you leave

Most of this market sells meetings. About half of it will not say who owns the domains, inboxes and workflows that produce them, and most of the meeting sellers will not say what counts as one. This is what 101 outbound and GTM engineering specialists actually publish, read off their own sites.

101: Outbound and GTM specialists, checked one by one
38: Publish a price at all. The other 63 do not
49: Do not say who owns the domains, inboxes and build when you leave
38: Sell meetings or leads without publishing what counts as a qualified one

The question nobody answers

When you stop paying, what do you keep?

Outbound runs on infrastructure: sending domains, warmed inboxes, enrichment tables, lists, workflows. Whoever owns them owns the engine. If they sit in the supplier's accounts, the pipeline stops the day the invoice does, and you start again from nothing.

So we checked what each of the 101 companies here publishes about it. 49 say nothing at all. 45 say the domains, the data or the build are yours to keep, and 7 say plainly that they own the sending infrastructure.

The split is not random. Of the 58 that run outbound for you, 38 are silent on it. Of the 43 that build a system for you to run, or offer both, 28 say you keep it, because a handover is the product they are selling.

The second silence sits in the result. 65 companies here sell meetings, replies or leads, and 38 publish no definition of a qualified one.

Here the split runs by how they bill. Of the 16 that charge per meeting or lead, 15 define what counts, because the definition is the invoice. Of the 49 selling meetings on a retainer, 37 do not. The ones you pay regardless are, mostly, the ones that never say what you are paying for.

Who keeps the infrastructure, by how the work is delivered

	Yours	Theirs	Silent
58 run it for you	17	3	38
7 build it for you to run	4	0	3
36 build and run it	24	4	8

Counted from what each company publishes on its own site, read in September 2026. This records what they say, not what they do. A company that is silent may well hand everything over; it simply does not say so where a buyer can read it before signing.

First decision

Nine different jobs share one label

Before price, decide what you actually need run. These differ in cost, in speed and in how much of your own team they take.

Search for a cold email agency and most of what comes back is a managed sending operation: secondary domains, warmed inboxes, a sequence and a calendar link. A cold outreach agency is often the same business with LinkedIn added. Neither label tells you whether anyone is building the list logic that decides who gets contacted, which is where most campaigns actually succeed or fail.

The counts are how many of the 101 run each motion, not how well. Two labels deserve a second look. A linkedin outreach agency is sending from a named person's account, usually yours or a founder's, so ask whose reputation is at stake. An appointment setting agency is selling people on the phone, and its price should say how many hours of calling it buys.

Every specialist

The directory

Start the filters with what you need run, then with whether you want it run for you or built for your team.

Every gtm agency below was checked against its own site rather than a review listing, and each card carries the two answers that matter most after price: whether you keep the infrastructure when you leave, and what the company counts as a result. A dash means it publishes nothing on that point.

A dash on a card means the company publishes nothing on that point, and it is the most common answer on both rows: 49 of 101 say nothing about who owns the infrastructure, and 38 of the 65 selling meetings or leads do not define a qualified one.

Buyer's guide

How to choose a GTM agency

Five questions, in the order they usually decide things. Every figure below is computed from the directory above.

1. Decide whether you are renting or building

A managed shop rents you an outcome from its own machine. A build leaves a system in your accounts that your team runs. A gtm consultant who designs the system and then leaves sits at the far end of the same line. Of the 101 here, 58 run it for you, 7 build it for you to run, and 36 offer both.

2. Get the definition of a result in writing

A positive reply, a booked meeting, a held meeting and a qualified opportunity are four different things, priced very differently. The broadest label on this market, b2b lead generation agency, covers all four. 27 of the 65 companies here selling meetings or leads publish what counts as a qualified one. Ask the rest before you compare prices.

3. A from-price is not a price

Entry prices in outbound usually leave something out: a setup fee for domains and inboxes, the data and tool costs, a minimum term, or the copy. 38 of the 101 publish a price at all. For the rest, the first call is the price list, so arrive knowing which of those four you are asking about.

4. Treat a free pilot as a sales process

13 companies here offer one. A pilot costs no fee, but the supplier chooses the segment, the copy and the infrastructure, so it proves their machine rather than yours. It is still worth running. Agree beforehand what a pass looks like and what you keep if you walk away.

5. Check the evidence you can actually check

Results tiles without a client name cannot be verified by anyone. Named case studies with a date and a client you can contact can. Every result on this page is reported as the company's own claim, and the reviews say which companies name their clients.

What the market charges

Monthly commitment bands for each gtm agency here, normalised so a per-meeting seller and a retainer shop sit on one axis.

Under $2,500/mo10
$2,500 - $5,000/mo12
$5,000 - $10,000/mo24
$10,000/mo and up15
Does not publish a price63

A company is counted in every band its published pricing spans, so the totals add up to more than 101. The last row is not missing data: it is the 63 companies that publish no price at all, which is a fact about how they sell.

By who you are

Builders, senders, and who they serve

Filter to the companies that name your sector on their own site, rather than the ones listing every industry on a landing page.

The newest group here is the builders. A Clay agency sells the enrichment and scoring logic rather than the sending, and a gtm engineering agency usually sells the whole system around it: signals, routing, CRM writes and the agents that research each account. They are the easiest to leave well, because what they sell is the thing you keep.

What we left out

52 we checked and did not list

The part of a directory nobody publishes, because producing it means opening every site.

The market uses a dozen names for the same work. An outbound lead generation agency, a go-to-market agency and a revenue partner can all describe the businesses below, and the label tells you nothing about whether a company sells outbound, sells software, or still trades.

Methodology

How we checked, and what we owe you

We opened 153 companies and kept 101. Every fact on this page was read off the company's own website in September 2026, not from a comparison article, a review site or another directory. Where a company publishes no price, this page says so rather than estimating one, and 63 of them publish none.

A disclosure the link building directory does not need. Frontal, ColdIQ and Arrel are clients or partners of busyless, and they are listed first for that reason. Nothing else about those entriesdiffers: the same fields, read the same way, with silences recorded as silences and limitations written as plainly as anyone else's. Each card and page says so too.

How the rest are ordered. After the longer reviews, companies are listed by how many of a buyer's key answers they publish: a price, who owns the infrastructure, what counts as a qualified result, a guarantee and who they take on. It is a count of published facts, not a rating of the work, which nobody outside a client list can judge.

No affiliate links and no listing fees. Nobody pays to appear here, and no position is for sale. Outbound links carry nofollow and we earn nothing if you hire anyone listed.

We record what companies say, not what they do. The ownership and result answers on every card report each company's own published words. A company that does not address a question is recorded as silent, never as doing anything wrong.

Published results are claims. Meetings booked and pipeline generated are reported as each company states them. Nobody outside a client list can verify them, and the pages say so rather than repeating them as fact.

No invented ratings. There is no star rating and no aggregate score. The scorecards on the expanded reviews are an editorial read of what each company publishes, across six dimensions, and stay out of the structured data. Third-party scores appear with a source, a count and a read date.

FAQ

Questions buyers ask

What does it cost to outsource outbound?
Of the 101 companies here, 38 publish a price at all. Among those that do, the entry figure is usually a monthly retainer, and it often excludes a setup fee for domains and inboxes or needs a minimum term. Compare what the entry price buys, such as channels, volume and who writes the copy, before comparing two numbers.
Should I pay per meeting or pay a monthly retainer?
Paying per result moves the volume risk to the supplier and the definition risk to you. 16 companies here bill per meeting or per qualified lead, and 15 of them publish what counts as qualified. A retainer buys effort you can inspect; a per-meeting price buys an outcome someone else has defined, so read that definition before comparing prices.
Who owns the domains and inboxes an outbound supplier sets up?
It depends on the supplier, and most do not say. 49 of the 101 here publish nothing on it. Ask before signing whether the domains are registered to you, whether the inboxes sit in your workspace, and whether the lists and enrichment tables leave with you. If the answer is no, the pipeline stops when the contract does.
What counts as a qualified meeting?
Whatever the contract says, which is why it should be written down. Useful definitions name the buyer's title and company size, require the prospect to attend, and say what happens to no-shows. 38 of the 65 companies here that sell meetings or leads publish no definition at all.
What is GTM engineering, and how is it different from lead generation?
Lead generation sells an outcome, usually meetings, produced on the supplier's infrastructure. GTM engineering sells a system: the enrichment, scoring, signals and routing that decide who gets contacted and when, usually built in your own tools, often in Clay. Some companies sell both. The difference matters most when the engagement ends.
Are free pilot campaigns really free?
13 companies here offer a free pilot or test campaign. It costs no fee, but it is a sales process: the supplier chooses the segment, and a pilot run on its own infrastructure proves its system rather than building yours. Ask what you keep from the pilot if you do not continue.
Why do so few outbound companies publish a price?
63 of the 101 here publish no price. Part of that is genuine, because a build is scoped to your data and stack. Part of it is commercial, because a gated price means a call. Either way it is a fact about how a company sells, so this directory records it rather than estimating a figure.
Why are some companies listed first?
Frontal, ColdIQ and Arrel are clients or partners of busyless, and they are listed first for that reason. Their cards and pages say so. Everything else about their entries is the same as everyone else's: the same fields, read the same way, with silences and limitations recorded plainly.

Outbound finds buyers. Content decides whether they believe you.

Every company above sells a way to reach people who have never heard of you. The first thing a prospect does after a good cold email is look you up, and what they find is a different job. busyless does not sell outbound. It owns the content system that outbound lands on: what gets published, why, and whether it earns the reply.
