The GTM agency for B2B go-to-market strategy and execution
A route to named buyerspipelinethe buying grouprevenue
GTM Quest is a GTM agency for US and UK B2B teams, based in London.
We define who you sell to and why they should choose you, then build the system that turns it into pipeline: LinkedIn, founder-led content, buying signals and outbound, running on a data layer you own.
We run it with you, or build it and hand it over. The data, the tooling and the playbooks stay yours.
For B2B SaaS, technology and services teams in the US, the UK and Europe.

01 / Our service
What our GTM agency builds for you
Six things, in order.
The last one is the one people forget to ask for.
Most agency scopes cover the first five. The sixth is what separates a supplier from a build.
The long read on each is our go-to-market agency guide.
What we
build
The account list
Who you are actually selling to this quarter: firmographics, the roles in the buying group and the trigger that starts a purchase.
02 / The GTM playbook · outbound setup
The whole motion, signal to meeting
Signals in, one account record, warm before outreach, then the handoff.
Tap any node. The tools named are the ones we run.
Listen
Signals in
Job changes, news, funding and site visits by company.
03 / The mechanism
Four channels, run as one system the Quest System
Each channel does something the other three cannot.
Running them together means the fourth gets easier every time the first three do their job.
72%
say ABM wins
17%
fully embedded
Most of the value in this category sits in the gap between those two numbers. Momentum ITSMA, 2023, 279 practitioners.
Channel 01
LinkedIn ads
Document and thought leader ads build recognition before anyone reaches out.
04 / System architecture
One database in the middle, everything else a spoke
Every channel reads from and writes to the same account record.
Signals flow in. Messages, posts and ads flow out. Tap a channel or a node.
The four channels
Channel 01
Direct, from the founder’s account
Connection requests and messages to people at accounts that just moved.
05 / The commercial model
Retainer or handover four ways to work with us
This decides what you are actually buying.
A retainer keeps the capability with the supplier. A handover puts it inside your company.
Every model comes with a weekly break clause and a full handover.
Ask any agency: whose name is on the tooling contracts?
Who should run the system once it is built?
Build and transfer
We build the system and hand it over. Documentation, training and knowledge transfer are included, and the tools are already in your accounts.
06 / How we start
We start the GTM motion on day one and build the system around it
M6
first revenue
Plan the cash for it. The only lever is starting conversations earlier.
Day 1
The motion starts
We agree the first accounts and start the conversations the same day, from your founder’s and team’s LinkedIn and warm introductions.
Week 1
The list, and the reason
Account definition, enrichment, and the one thing you will say that a competitor could not. Tested against the first replies.
Weeks 1 to 4
The infrastructure
Domains warming, deliverability tested, enrichment wired, CRM writeback proven before the first cold email.
Weeks 2 to 4
Channels join as they are ready
Ads and content to the full list, then signal-led outbound as the domains come ready.
Months 2 to 3
Scale, then handover or not
Cut what is not working, scale what is, then decide with you who runs it. A decision point, not a milestone.
What day one does not contain is revenue. Ebsta and Pavilion, 2023: deals close best at 31 to 60 days for small deals, 61 to 90 for medium, 150 to 180 for larger ones.
Sales cycles lengthened 32% year on year. 3.2 million opportunities across 364 companies (Ebsta and Pavilion, 2023).

09 / The choice before the choice
Agency, consultant, advisor, recruiter or hire who holds the work when it ends
Five different things get bought, and they are not substitutes.
They differ on one axis more than any other.
What they do
Design the route and operate it
Diagnose the problem and specify the answer
Speed
The motion on day one
Days to a plan
You end up with
A running motion, and a decision about who runs it
A plan, and the execution problem you started with
Best when
There is no internal operator and no motion yet
You have a team that can build and lack direction
→ We do both, and will tell you which one you need.
Gartner, March 2026: 67% of 646 buyers prefer a rep-free buying experience, and 45% used AI during a recent purchase.
Whoever you buy, they are building for a buyer who would rather not meet them.
10 / GTM agencies
GTM agencies: seven kinds, one label
“GTM agency” covers firms that do very different work.
Most of the GTM agencies you will find are specialists in one or two of these. Pick by the gap you need filled.

Go-to-market services and what is in scope
What a go-to-market strategy service includes, as one engagement.
Then the question that changes what you own: GTM as a service, or outsourcing?
GTM
services
Go-to-market strategy
ICP, positioning, pricing input and the channel plan.
Your tools, your accounts
A function you could run yourself, run by someone else on your own tooling. This is how we work.
13 / The basics
What is a go-to-market strategy? in five questions
A go-to-market (GTM) strategy is a company’s plan for reaching its customers and winning them.
In B2B it answers five questions. What does GTM mean in business? Go-to-market: the plan and the machinery for taking a product to its buyers.
The long version is our guide to go-to-market strategy.
The ICP
Who to sell to
Industries, sizes and roles that buy.

A go-to-market plan framework and examples
A strategy becomes a go-to-market plan when it has owners, dates and numbers.
There is no single right framework. Gartner’s and Harvard Business School’s are good starting points.

15 / The system
GTM engineering and Clay the system under the strategy
GTM engineering builds the data and automation behind a go-to-market motion.
A GTM engineer builds it: part RevOps, part data engineer, part marketer. Most of it runs in Clay.
We pair Clay with a Postgres database above the CRM, so you own the data and the history. See GTM engineer.

Tools change; the jobs don’t. This is our current stack, chosen per client.
We work with what you already have where it does the job.

Tools we use
Why
One system of record above the CRM that you own, with the full history of every account and touch.
17 / How onboarding works
From signature to first conversation, as one flow
Signing is the trigger. Everything after it is built in your accounts, not ours.
Two views: the shape at a glance, or the full workflow.
Day 0
Signed: the trigger
Signing starts the build. No discovery phase, no workshop deck.
18 / LinkedIn content engine
From ideal buyer to pipeline
Content is the channel that makes the cold message warm.
It runs as a system: who reads it, what has worked, which format, which stage of the funnel, then the handoff to pipeline.
Who
Define the ideal buyer
The roles in the buying group, and what they already read.
19 / The months after
What happens month by month once the motion is running
The question most agency pages skip, in the order it happens.
Month one
Conversations, and the build around them
Month one
Conversations, and the build around them
Almost all the work is diagnostic: which segment answers, which subject line does not, which enrichment field is wrong more often than right.
If an engagement is going to be stopped, it is almost always stopped in month two, on a number that has not had time to mean anything yet.
That is the argument for a weekly break clause rather than a twelve-month term.
20 / ROI and forecasting
Return on investment and a pipeline forecast
Your numbers, not ours. Every input is a slider, and every output follows from them.
The defaults are placeholders. Replace them with your own.
Meetings ramp to the monthly figure by month 3. Revenue lands one sales cycle after the opportunity (your cycle from day one: 150 days).

Each has its own page with how we run it, what it costs in the market and the US and UK rules that apply.

Win rate × deal value ÷ sales cycle. 1.0x is the average. Outbound is only average on its own, which is why we run it warm.
22 / Consulting or agency
Advice, or a GTM agency that builds and runs it?
Go-to-market consulting is advice on who to sell to, how to position and which channels to use, usually delivered as a plan.
A GTM agency does that and then builds the system.
Slide to how much you want built and run.

Built, and run or handed over
The route is designed, built and operated, then you decide who keeps the keys.
23 / Who we work with
Go-to-market for B2B SaaS and startups after product-market fit
Most of our work is with B2B SaaS, fintech, technology and services companies that have proven people will buy, but have not made revenue repeatable.
That is the stage where go-to-market work pays back fastest. See also GTM agencies for startups.
Our sweet spot
Make revenue repeatable
For early-stage teams we usually build around the founder (their LinkedIn presence and their outreach), then hand the system to the first sales hire.
B2B SaaS, fintech, technology and services
24 / The team
GTM team, motion and RevOps who runs it after us
A GTM team is everyone who turns the plan into revenue: marketing, sales, customer success and revenue operations.
The GTM motion is how they work together. RevOps is the plumbing that connects their data and handoffs.
The handoffs are where pipeline leaks, so every engagement ends with the definitions written down.
Sales-led
Reps run the deal
Marketing builds the account list and the warmth; sales runs discovery to close.
Average SDR ramp before they are productive (Bridge Group, 2025). So we prove the motion first and hire into it second.

25 / How we engage

Both suit companies that need the expertise before they can justify the headcount.
For a part-time marketing leader rather than a system, our sister site Fractional Quest covers fractional CMOs.

Senior leadership, part-time
Senior go-to-market leadership for one or two days a week: our Handover + support and Embedded models.
26 / Cost
What a GTM agency costs two numbers, not one
The build is a one-off.
The running cost is monthly and never stops: data, enrichment, sending, ad spend and tools.
We quote in writing after the discovery call, with tools, data and media as separate lines.
A system you cannot afford to feed is not an asset. It is a subscription you have been made responsible for.

For startups, what to expect to pay depends more on the running cost than the build. How agencies structure fees is in our GTM agency pricing guide.
