How to Choose a Go-to-Market Partner in 7 Steps

You know you need outside go-to-market help. The problem is that the options blur together. An advisor, a fractional CRO and an operator-investor can all describe their work in almost identical language, and at pre-seed or seed a wrong pick costs you two quarters you do not have. The fix is not a better gut feel. It is a process.

What follows is the seven-step process we use at dm(v) when founders ask us how to evaluate this kind of partner, including the ones who end up choosing someone else. It covers stage fit, reference checks, the engagement model and a 90-day pilot with exit criteria.

What you need before you start

Two things, both of which take an hour to write down.

• A list of the specific decisions you cannot make alone. Not "we need sales help". More like: which segment to double down on, how to price a usage component, whether to hire a founding seller or a second technical AE.
• An honest read on your stage. Are you still the demo, the follow-up and the signature on every deal? Or do you have one or two reps in ramp and the problem is consistency?

If you cannot answer the second one cleanly, start with the go-to-market foundation before you talk to anyone.

(01) Define the gap you are hiring for

Three different gaps get bundled under "go-to-market partner", and each points to a different kind of person.

The first is building the motion: turning what works on your calls into something another person can run. The second is running revenue part-time: managing a team that already exists, owning a forecast, sitting in your leadership meeting. The third is opening doors and capital: an investor who makes introductions where cold outreach dies.

Most pre-seed and seed founders think they want the second and actually need the first. If you have no reps yet, there is no revenue team to run. What you need is someone who helps you build the repeatable motion underneath your first revenue engine, not someone who takes the deals off your desk.

(02) Match the partner type to your stage

Stage fit is the single highest-signal filter. Use this mapping as a starting point.

• Pre-seed to seed: an advisor or operator-investor who has built a first motion from zero. Cadence is regular 1:1 sessions, closer around a fundraise.
• Seed to early Series A: the same profile, plus help defining the first commercial hires and joining live calls during the handover.
• Series A and beyond, with a team already in place: this is where a fractional CRO or interim revenue leader starts to make sense, because there is something to lead.

Context matters here. In Supabase's 2026 survey of around 2,000 startup builders, half of respondents ran a product-led growth motion, and dedicated full-time sales hires usually did not arrive until after the tenth employee (Supabase). A partner whose entire playbook assumes an inside sales floor will not be much use to you. Our breakdown of go-to-market partners by stage maps the main models if you want to compare categories side by side.

Also work out what motivates the person. Some advise to build a network, some for financial upside, some because they like operating. All three can work. Not knowing which one you are dealing with is what causes the relationship to go quiet in month four.

(03) Build a shortlist using the right signals

Aim for six to ten names per gap, not two. The profiles that tend to work best at this stage, roughly in order:

1. Post-Series B founders who sold a technically complex product themselves.
2. Active angels in your category who have recent, specific knowledge of your buyer.
3. Operators who built a go-to-market function from the ground up, not inherited one.
4. Senior corporate leaders, useful mainly for buyer-side insight and introductions.

Filter on stage-relevant experience, not logos. Someone who ran a 60-person revenue organisation at a Series C company has usually forgotten what it feels like to have no pipeline, no brand and no case studies. The relevant question is whether they have done your next twelve months, recently. If part of the brief is helping you make a first commercial hire, check they have opinions about hiring your first sales rep that go beyond a job description.

(04) Score candidates on four criteria

Keep the scorecard short enough that you actually use it. Score each candidate from 1 to 5 on four things:

• Stage fit: have they done this at your stage, with your deal size and cycle length?
• Comparable outcomes: can they name anonymised companies of similar shape and say what changed?
• Engagement clarity: are scope, time commitment, cadence and decision rights clear before money is discussed?
• A concrete 30-to-90-day plan: do they describe measurable ramp metrics, or do they describe a framework?

Anyone scoring below 3 on engagement clarity is a pass, however strong the rest looks. Vague scope is the most common cause of an advisory relationship quietly decaying. The traits that predict a good go-to-market hire apply here too: evidence of achievement, coachability and specificity under questioning.

(05) Run reference checks and interview for specifics

Interview for detail, not philosophy. Three questions that separate operators from commentators:

1. What did the first 30 days look like with your last company at my stage? Walk me through the calendar.
2. Which deal did you sit in on, and what did you change about the discovery?
3. What did you get wrong there, and how did you find out?

Vague answers are a disqualifier. Then take references off-list. Ask former founders specifically about the handover: what happened when the founder stepped back from calls, and whether the partner was still around when it got messy. The same back-channel logic works for commercial hires, and for good reason.

(06) Negotiate the engagement model

Settle four things in writing before anyone signs.

• Scope: which decisions, which artefacts, which calls.
• Time: hours per month, named cadence, and what happens around a raise.
• Compensation: cash, equity or hybrid. Among advisor equity grants issued by pre-seed companies on Carta in the first half of 2024, the median grant was 0.21% of company shares (Carta). Treat that as a reference point, not a rule.
• Decision rights: the partner advises and builds. You decide. Say it out loud.

If the person also wants to invest, separate the two conversations. Investment can strengthen alignment, but it should not be the reason you skip diligence on the advisory work.

(07) Structure a 90-day pilot with exit criteria

Nobody should commit to two years on a first impression. Agree on two or three measurable milestones and a clean thirty-day exit on either side, with unvested equity returning.

Pick leading indicators, not closed revenue: qualified pipeline created from the new segment, stage-to-stage conversion on discovery, and the number of calls where a rep ran the demo without you. Call quality is worth measuring directly, and a partner who does not touch live calls cannot move it.

Troubleshooting: where these engagements fail

Three failure patterns show up again and again.

Frameworks without calls. You wanted hands-on, they meant monthly strategy. Fix it in Step 6 by naming how many live calls they join per month.

Vesting on time, not output. Equity keeps vesting while the calls thin out. Tie the first tranche to the pilot milestones from Step 7.

Volume advice that damages the brand. Some partners default to more outreach as the answer to everything. In a Gartner survey of 632 B2B buyers, 73% said they actively avoided suppliers that sent irrelevant outreach (Gartner). In Supabase's survey, 67% of respondents had not tried paid customer acquisition at all, up from 62% the year before. Precision beats volume at your stage.

Key takeaways

• Write down the three decisions you cannot make alone before you talk to a single candidate.
• At pre-seed and seed, choose someone who builds the motion with you rather than someone who runs revenue part-time.
• Disqualify any candidate who cannot describe their first 30 days at a comparable company in concrete detail.
• Put the engagement on a 90-day pilot with two or three leading metrics and a thirty-day exit on both sides.
• Tie the first equity tranche to pilot milestones, not to the calendar.

Next steps

Run the seven steps in order and the choice usually makes itself by Step 5. Start with the decision list, keep the pilot short, and measure the handover rather than the hours. If you want a view on which model fits your stage, you can ask Dajana directly.
