When should a startup hire a product marketing consultant? (And when to hire full-time)

The reality is that it's earlier than you think. Here are the signs it's time.

Key takeaways

Hire a product marketing consultant earlier than you think: as soon as something in your go-to-market feels off, even if you can't say exactly what. Figuring out what the problem actually is, and testing the fix in the market, is a big part of the job.

Most founders wait until they have a clear problem to hand over. By then they've usually guessed at the cause, wasted a ton of time, or even hired for the wrong fix: a demand gen marketer for what's really a positioning problem, or more reps for a story that only the founder can successfully tell.

First up, let's talk about what a product marketing consultant even does.

What a product marketing consultant does for start-ups

A product marketing consultant owns the decisions about how your product is understood and bought. That means:

Running ads and demand gen programs usually sits with a demand gen marketer or an agency, and week-to-week ownership of the story sits with a full-time Marketing hire. I wrote more about where product marketing ends and go-to-market begins in GTM and PMM are not the same job, it's worth understanding the difference.

Why to hire a product marketing consultant before you have a defined problem

The first item on that list is the one founders skip. They assume they need to know what's broken before they bring someone in, so they spend months on their own theory of the problem first.

The trouble is that founders are the closest people to the product, which makes it hard to see how buyers actually see your product. Everyone on the team usually has their own explanation for why things are slow.

But when you find a great consultant, they'll spend the first few weeks digging into your business to find out what's really going on. What's actually broken, and why. That's gold for smaller companies.

That also means it's not too early if you're still pre-launch or have very few customers. The work then is testing: which segment responds, which message gets a reply, what people will pay for. (If that's you, see how to build a go-to-market strategy if you have zero customers.)

You don't need the answer to hire. All you need is to know that something feels off.

Signs it's time to hire a product marketing consultant

These are the signs I'd use to signal whether I need a product marketing consultant. If one or two sound familiar, I'd start the conversation now, even if you're not sure which one is the root cause.

When to consider hiring a full-time product marketer

A consultant gets the decisions made and tested. As the company grows, some of the signs above, like more and more features shipping, turn into weekly work. Someone needs to own it inside the company. In my view, a full-time product marketer should be one of the first 20 people you hire at a tech company. You might want to consider a full-time hire if you're in one of these situations:

Product marketing consultant vs full-time PMM vs agency

Put side by side, the three options do different jobs:

OptionBest whenWhat you get
Product marketing consultantSomething's off and you need it found and fixed, or you have a scoped push: a launch, a repositioning, a new segmentDiagnosis, decisions tested in the market, and the assets built on them, in a finite engagement
Full-time PMMThe story needs looking after every week: new releases, sales cycles, ongoing enablementContinuous ownership inside the company
AgencyStrategy is already clear and you need volumeThroughput: campaigns, content and programs in market

These aren't either-or. One order I like: a consultant first to find the problem and make the decisions, then a full-time hire who runs with them, with an agency added once there's a clear brief to execute. That also makes the full-time hire easier, because you're recruiting for a defined job.

What to have ready before you hire a product marketing consultant in your start-up

Since you don't need a defined problem, the bar here is low. Have these four things in place before you sign anything:

Once you have those, use these questions to ask a go-to-market consultant to compare the people you talk to.

What good looks like after you hire a product marketing consultant

A few weeks in, you should have a named problem and decisions you can argue with: a named ICP, positioning that leaves some buyers out on purpose, and a core claim sales can repeat. If you're looking at a polished deck that still keeps every option open, ask why.

By the end of the engagement, your team should be able to run the work without the consultant in the room:

If you're heading into a launch, how to prevent a failed product launch covers what to lock before launch day, and what to do if your product launch failed covers the other side.

Questions I get on this topic

When should a startup hire a product marketing consultant?

Earlier than most founders think: as soon as something in your go-to-market feels off, even if you can't name the problem yet. Finding the problem and testing the fix is part of the job.

Do I need a defined problem before I hire a product marketing consultant?

No. A list of symptoms is enough, like deals stalling after the demo or prospects comparing you to the wrong competitors. Working out the cause from customer and sales evidence is the first part of the engagement.

How do I know if I need a product marketing consultant?

Look at what's breaking. If prospects don't understand why you're different, deals stall without a clear reason, sales can't sell without the founder, or a launch is coming without an agreed ICP, that's product marketing work.

Is it ever too early to hire a product marketing consultant?

Not usually. Even before you have customers, a consultant can help you test segments and messages in the market so your first go-to-market choices are based on how buyers respond. The one thing you need is a founder ready to make the decisions the work turns up.

When should a startup hire its first full-time product marketer?

Once the work is weekly and ongoing: frequent releases, a sales team that needs regular enablement, and tested positioning that needs looking after. In my view, that hire should be within your first 20 people.

Is a fractional PMM the same as a product marketing consultant?

They overlap. Fractional usually means ongoing part-time hours on a retainer. A consultant engagement is usually scoped to one problem with an end date. Plenty of people offer both.

What should a product marketing consultant deliver?

A clear read on what's actually wrong, decisions your team can act on (ICP, positioning, core messaging), and the material that puts them to use, like sales talk tracks and launch assets. Your team should be able to keep using it after the engagement ends.

Where does a startup start looking for a product marketing consultant to hire?

Start with consultants who specialize in early-stage go-to-market work. I'm one of them: I run [More Than Said](https://morethansaid.com), a product marketing and GTM strategy company for startups.
