GTM advisor go-to-market advisory from London
A GTM advisor helps a B2B team make the go-to-market decisions that everything else depends on: who to sell to first, what to say, which channels to use and when to hire.
GTM Quest offers GTM advisory as an engagement, led by operators who have built and run these systems.
We write every decision down, start the motion on day one, and tell you plainly what we would do next.
If you want more than advice, we also build the system and run it with you, or hand it over.

01/ our GTM advisory
What our GTM advisory covers six decisions, written down
Most go-to-market problems are a decision nobody has made yet.
Our GTM advisory works through these six in order, and each one ends as a written decision with an owner on your side.
01
ICP and the first segment
Which customers you win most easily, and which segment to win first.
We look at closed deals, lost deals and the accounts sales already cares about, then write the ICP down with your sales lead.
- ✓ A written ICP
- ✓ One beachhead segment
- ✓ Disqualifiers, not just fits
02
Positioning and the message
What buyers compare you with today, what only you do, and the words that make that clear.
The output is language your website, outbound and sales deck can all use.
- ✓ Competitive alternatives
- ✓ Differentiated value
- ✓ A message tested with buyers
03
Channels and sequencing
Which channels reach your buyers, in what order, and what each one is for.
We advise against adding a channel before the one before it is working.
- ✓ Channel choice by segment
- ✓ What to stop
- ✓ A sequence your team can run
04
Pipeline and the numbers
Where pipeline really comes from, where deals stall, and which few measures tell you the motion is working.
We agree what counts as a qualified meeting before anyone reports on it.
- ✓ Source of pipeline
- ✓ Stage definitions
- ✓ Weekly and monthly measures
05
Hiring and the team
When to hire, which role first, and how to tell whether the motion is ready for a hire.
We help write the role and the scorecard, and sit in on interviews if you want us to.
- ✓ Role design
- ✓ Interview scorecards
- ✓ A playbook the hire inherits
06
The GTM plan
The decisions above, on one page: segment, message, channels, owners, measures and the next review date.
It is a plan your team can run without us in the room.
- ✓ One page, not a deck
- ✓ Owners and dates
- ✓ A review rhythm
Advice is the start, not the limit.
We are a London GTM agency, so when a decision needs building (the account list, the data layer, outbound, content, LinkedIn), we can build it with you.
A useful self-check before any call: our GTM scorecard covers the same ground as our first week of advisory.
02/ how it can run
GTM advisory engagements pick the level of involvement
GTM advisors work in different ways, and so do we.
Pick the one closest to what you need to see what it involves and who does the work.
How much help do you want?
Advisory
Advisory only
A senior go-to-market advisor works with the founder or revenue leader on a regular rhythm.
Your team carries out the plan; we pressure-test the decisions, review the evidence and say what we would change.
- ✓ Regular working sessions
- ✓ Written decisions after each one
- ✓ Reviews of pipeline, messages and channels
- ✓ Your team owns delivery
Best when you have people to do the work and need judgement on what to do.
Advisory and build
Advisory with the build
The same advice, plus the system that carries it out: the account list, the data layer, outbound, content and LinkedIn.
We build it with your team so they can run it.
- ✓ Everything in advisory
- ✓ Account list and data layer
- ✓ Channels set up and tested
- ✓ Documentation as we go
Best when you know what to do but lack the hands or the tooling.
Embedded
Advisory, built and run
We advise, build and run the motion alongside you, reporting weekly on meetings held and monthly on pipeline created.
- ✓ Everything in advisory and build
- ✓ Day-to-day running
- ✓ Weekly and monthly reviews
- ✓ A break clause either side
Best when there is no one in-house to run go-to-market yet.
Handover
Advise, build, then hand over
We set the direction, build the system, prove the channels and then hand the playbook to the person you hire.
You keep the data, the lists, the domains and the documentation.
- ✓ A proven, written playbook
- ✓ Role design and interviews
- ✓ Training for the new hire
- ✓ A clean exit
Best for founders moving on from founder-led sales.
What it costs. Every engagement is scoped and quoted in writing after the discovery call.
Data and tools are separate lines, so you can see what you are paying for.
03/ the first weeks
How we work as your GTM advisor the motion starts on day one
Advice that waits for a perfect plan is advice nobody tests.
So the motion starts on day one, and the decisions are made alongside the first real conversations.
- 01
The call
Fifteen minutes on what you sell, who to and which decision is stuck. Afterwards you get a written next step, whether or not you work with us.
BEFORE - 02
Start the motion
The first target accounts agreed with you, and conversations started the same day from the founder and team LinkedIn, warm introductions and existing contacts.
DAY 1 - 03
Diagnose
Closed and lost deals, pipeline sources, channels and customer interviews, read alongside the first replies. One written constraint and the decision it needs.
WEEK 1 - 04
Decide
ICP, positioning, the first segment and the channel sequence, agreed with the founder and sales and tested in live conversations.
WEEKS 1 TO 2 - 05
Build around it
If you choose the build, the account list, data layer and channels join one by one as they are ready. If not, your team builds and we review.
WEEKS 1 TO 4 - 06
Advise, run or hand over
At the review you choose: keep us as your GTM advisor, have us run it, or take it in-house with the playbook, the data and the training.
MONTHS 2 TO 3
The handover-or-not choice is yours, and it is written into the engagement from the start.
A GTM advisor who plans to stay forever is a cost, not an investment.
04/ definition
What is a GTM advisor? judgement on the decisions that matter
A GTM advisor (go-to-market advisor) is a senior operator who helps a company decide how it will reach and win its customers.
They do not usually run the channels themselves; they help the founder and revenue leaders make better decisions about them.
Harvard Business School Online describes a go-to-market strategy as a detailed plan of how a startup will reach its target customers, and names three facets every strong one considers: distribution channels, product messaging and marketing tactics, and the estimated customer acquisition cost.
A good GTM advisor has made those calls before, at your stage, and knows which one to make first.
The Harvard Business School Rock Center's session summary on go-to-market makes the point that matters most for advisory: the strategy is never finalised, and for early-stage companies the founders must own it.
That is why we treat GTM advisory as support for the people who own the decisions, not a replacement for them.
What does a go-to-market advisor do?
Day to day, a go-to-market advisor reads the evidence (deals, pipeline, calls, customer interviews), asks the questions the team has stopped asking, and helps turn the answers into decisions.
They review messaging and channel plans, sit in on pipeline reviews, help with key hires and introduce people where it helps.
The best ones write things down.
A decision with a reason and an owner survives the advisor leaving; a good conversation does not.
GTM advisors and GTM advisory firms
"GTM advisors" are usually individuals: former revenue leaders, founders or operators who advise a handful of companies.
"GTM advisory" can also mean a firm, such as ours, that provides the same senior advice with a team behind it who can build what the advice calls for.
For a broader view of firms that work on strategy and system design, see our guide to GTM consultants.
05/ options
GTM advisor vs consultant, fractional leader, agency or non-executive which one fits
Five kinds of senior go-to-market help overlap in name and differ in what you actually get.
Pick a tab to compare a GTM advisor with each.
→ Many consultants also advise, and many advisors take on projects. See our guide to GTM consultants for the project route.
→ For the trade-offs between a part-time leader and an outside team, read fractional GTM manager vs agency.
→ GTM Quest is both: senior GTM advisory, and a go-to-market strategy agency that can build and run what the advice calls for.
→ A non-executive director is a company director in law, so the role carries duties an advisor does not. See the section below.
For the wider choice between an outside team and a hire, see in-house vs a GTM consultant.
06/ board roles
GTM advisor, board advisor or non-executive director? the legal difference
An advisory board and a board of directors sound alike and are not.
A GTM advisor, or a member of an informal advisory board, gives advice; a non-executive director is a director of the company.
The explanatory notes to the Companies Act 2006 say the term director covers an executive director, a non-executive director who has been properly appointed, and a de facto director.
The general duties in sections 171 to 177 of the Act are owed by a director to the company.
GOV.UK lists those duties for every director: follow the constitution, promote the success of the company, use independent judgement, exercise reasonable care, skill and diligence, avoid conflicts of interest, refuse third-party benefits and declare interests in transactions.
An advisor who starts directing the board can drift into the role without the title.
Section 251 defines a shadow director as a person in accordance with whose directions or instructions the directors are accustomed to act, and adds that a person is not a shadow director only because the directors act on advice given in a professional capacity.
So keep the line clear.
A GTM advisor recommends and the board decides; a non-executive director decides with the board and carries the duties that come with it.
This is not legal advice; speak to your company lawyer about any board appointment.
07/ by stage
When to hire a GTM advisor what GTM advisory looks like at each stage
The decision that matters changes as a company grows.
Here is what we would focus a GTM advisor on at each stage.
Early-stage B2B software: find the first repeatable customer
The founder is the sales team, and should be.
The best go-to-market advisors for early-stage B2B startups help the founder pick one segment, write the first message and learn from every conversation, without pretending there is a playbook yet.
- ✓ One segment, written down
- ✓ Founder-led outreach and content
- ✓ Discovery calls that test the message
- ✓ No hires until the pattern repeats
Series A B2B SaaS: turn founder-led sales into a motion
The question becomes whether anyone other than the founder can sell.
Good GTM advisory for a Series A B2B SaaS company documents what the founder does, builds the first channel that does not depend on them, and helps hire the first sales and marketing people into a motion that already works.
- ✓ A documented sales motion
- ✓ The first scalable channel
- ✓ Stage definitions and pipeline reviews
- ✓ Role design for the first hires
Series B: add segments without losing the first
Growth now depends on a second segment, a second product or a second region.
An advisor helps choose which, protects the core motion while the new one is tested, and sets measures that show which is working.
- ✓ Next segment or region chosen with evidence
- ✓ A bounded test, with a stop rule
- ✓ Marketing and sales on shared definitions
- ✓ Leadership hires and their scope
Scale-ups: fix the constraint, not the symptom
A B2B GTM advisory firm for scale-ups earns its keep by naming the one constraint holding revenue back (segment, message, channel, sales process or data) when the business is too busy to see it.
- ✓ A source-of-pipeline review
- ✓ Win and loss interviews
- ✓ One constraint, one plan
- ✓ Revenue operations that report the truth
Entering the UK or Europe
For overseas companies coming to the UK, and UK companies going into Europe, a GTM advisor helps pick the first segment, test the message with local buyers and decide what to run locally and what to run from home.
- ✓ Beachhead choice
- ✓ Local message testing
- ✓ UK GDPR and PECR handled
- ✓ A local account list
Whatever the stage, prove the motion before you hire into it.
The Bridge Group found new in-house SDRs take 3.0 months on average to ramp, with 40% median annual attrition, across 351 companies.
If you are deciding between hiring and outside help, our GTM salary guide shows what the in-house roles cost.
08/ what you get
What good GTM advisory produces decisions, not decks
You can judge any GTM advisory engagement by what is left when it ends.
These are the artefacts we would expect, ours included.
If you want a written playbook format to hold these decisions, our GTM strategy playbooks guide shows how other teams structure theirs.
09/ how buyers buy
Why GTM advisory matters more now the decisions are made earlier
Buyers make up their minds before they talk to you.
6sense's 2025 study of more than 4,000 buyers found 94% of buying groups had ranked their preferred vendors before first contact, and bought from that early favourite 77% of the time.
They also want to do much of the work alone.
Gartner found 61% of B2B buyers prefer a rep-free buying experience, and 73% actively avoid suppliers who send irrelevant outreach, in a survey of 632 buyers.
More people are involved, in more places.
Forrester puts a typical purchase at 13 internal stakeholders and nine external influencers, and McKinsey's B2B Pulse found buyers use an average of ten interaction channels, up from five in 2016.
Put together, the segment, the message and the channel mix are decided long before a sales call can fix them.
That is the judgement a GTM advisor is for, and why getting it wrong is expensive.
10/ choosing one
How to choose a GTM advisor questions to ask, and what a good answer sounds like
Ask every GTM advisor on your shortlist the same questions, including us.
Vague answers are an answer.
For a longer checklist, see how to choose a GTM consultant; most of it applies to advisors too.
11/ walk away
Red flags when hiring a GTM advisor what we would question
Advice before diagnosis
If the answer arrives before they have seen your deals and pipeline, it is a template.
Guaranteed pipeline or revenue
Nobody can promise what your market will do.
Ask what they will deliver instead.
Experience at the wrong stage
Running a large sales team is a different job from finding the first customers.
Ask what they did at your stage.
Figures without sources
Benchmarks with no link are opinions.
Ask where every number came from.
No written output
If nothing is written down, the advice leaves with the advisor.
Equity with no commitments
Equity for an advisor should come with a defined commitment, a vesting schedule and a cliff.
Without them, it is a gift.
12/ how advisors are paid
Equity vs paid GTM advisory how it usually works
Individual GTM advisors to early-stage companies are often paid in equity; firms and project advisors are usually paid in fees.
One widely used template for equity advisors is the Founder Institute’s FAST agreement.
The Founder Institute's FAST agreement (Founder / Advisor Standard Template, Version 3, July 2026) sets those grants by company stage and level of help, includes a three-month cliff on vesting, and gives an example of an expert pre-seed advisor vesting over two years.
It also names a strategic level, with no percentage in the published table.
The Founder Institute says FAST is aimed at founders and senior executives in advisory board roles, and is not designed for traditional project consulting and work-for-hire relationships.
It also says it is not uncommon for a technology startup to set aside a 5% pool of equity for a group of advisors.
In the UK, check the tax route before you grant anything.
GOV.UK says EMI options require the holder to work at least 25 hours a week, or 75% of their working time, for the company, which most outside advisors will not, so ask your accountant which scheme fits.
Paid advisory is simpler to set up and easier to end.
If you pay an individual through their own limited company, the off-payroll working rules (IR35) may apply, and for most medium and large clients the client decides employment status.
Engaging a firm to deliver defined work is different.
This is not tax advice.
GTM Quest is paid in fees, not equity.
Every engagement is scoped and quoted in writing after the discovery call.
13/ B2B SaaS
B2B SaaS GTM advisor what a firm adds, and on-demand vs traditional
A B2B SaaS GTM advisor works on the decisions specific to subscription software: who the product is for, how buyers trial it, where sales comes in, and how expansion and renewal feed pipeline as well as new logos.
Trials are now part of most buying journeys: Forrester found more than 60% of business buyers use a trial, and procurement is a decision maker in 53% of buying cycles.
A SaaS advisor helps decide how the trial, the sales conversation and procurement fit together.
What are the benefits of a B2B SaaS GTM advisory firm?
An individual advisor brings one career's worth of pattern recognition.
A B2B SaaS GTM advisory firm adds three things: more than one senior view on a hard decision, continuity when one person is unavailable, and people who can build what the advice calls for.
The trade-off is that you may not get the same person every time.
Ask who your advisor will be, and make that person a named part of the engagement.
Are on-demand GTM experts better than traditional consultants?
It depends on the shape of your problem.
On-demand GTM experts and advisors suit a stream of decisions that need a senior view quickly; a traditional consultancy suits one large question with a defined scope and a deadline.
On-demand help is usually faster to start and easier to stop.
A traditional project usually goes deeper on a single question.
Many teams use both: an advisor for the weekly decisions and a project for the occasional big one.
If you want to assess an individual expert, our GTM expert page sets out what to ask.
Account-based go-to-market
If your market is a few hundred named accounts rather than thousands, the advice changes: account selection, buying groups and coordinated plays matter more than volume.
That is the work we do as an ABM agency.

GTM advisor FAQ
What founders and revenue leaders ask before they hire a GTM advisor, and about how our GTM advisory works.
A senior operator who helps a company decide how it will reach and win its customers: the segment, the message, the channels, the pipeline and the hires.
A GTM advisor usually advises the people who own those decisions rather than running the channels.
Reads the evidence (deals, pipeline, calls and customer interviews), helps the team make and write down decisions on ICP, positioning, channels and hiring, and reviews how those decisions perform.
Senior go-to-market advice delivered as an ongoing engagement, by an individual or a firm.
At GTM Quest, GTM advisory ends in written decisions with owners on your side, and can extend to building and running the system.
An advisor usually gives ongoing judgement over months; a consultant usually delivers a defined project, such as a strategy or a system design.
The labels overlap.
See the comparison and our guide to GTM consultants.
No. A non-executive director who has been properly appointed is a director in law and owes the general duties in the Companies Act 2006.
An advisor advises the company and is not a director.
See board roles.
When go-to-market decisions are stuck or keep being revisited: choosing a first segment, moving on from founder-led sales, entering a new market, adding a segment, or before your first sales and marketing hires.
One that has taken a company from founder-led sales to a repeatable motion before, documents what the founder does, and helps hire into a motion that already works.
Ask for a specific example at Series A, not a general track record.
Operators who have found the first repeatable customers for a B2B product themselves, and who help the founder own the go-to-market rather than take it over.
Harvard Business School's Rock Center notes that for early-stage companies, the founders must own it.
Individual advisors to early-stage companies are often paid in equity; the FAST agreement sets grants from 0.10% to 1.00% depending on stage and level of help.
Firms and project work are usually paid in fees.
It depends on seniority, time and whether the work includes building anything.
We could not find a published survey of advisor fees we trust, so we do not quote a range.
Our own work is scoped and quoted in writing after the discovery call.
If you pay an individual through their own limited company, the off-payroll working rules may apply, and for most medium and large clients the client decides employment status.
Engaging a firm to deliver defined work is different.
This is not tax advice.
Many cannot, which is why advice sometimes goes unused.
We can: we are a London GTM agency as well as an advisor, so the account list, data layer, outbound, content and LinkedIn can be built with your team, then run together or handed over.
The motion starts on day one, with the first target accounts and conversations from your own team's LinkedIn, warm introductions and existing contacts.
The written decisions follow in the first weeks, tested against those conversations.
Yes.
We are based in London and work with B2B teams across the UK and Europe, and with overseas companies entering the UK.
