Agency vs First Product Marketing Hire: The Decision That Quietly Shapes Your SaaS Growth

As a product marketing studio, we deal with early-stage SaaS founders daily, and most early-stage SaaS founders think, “product marketing is important once the traction starts.”

Honestly, I don’t know what “we’re too early” means when it comes to early-stage SaaS starting their marketing.

When in reality, product marketing decides how the traction shows up, who it attracts, and whether growth compounds or plateaus. 

I’ve had long conversations with funded and bootstrapped founders on ‘agency vs first product marketing hire’ and honestly it does shape your SaaS growth trajectory but only if done right and strategically.  I’ve seen founders opting for agencies for the first few months, only to flatline with the most clichéd activities that don’t even make sense after a while, or hiring their first “founding marketer” only to let them go between 6–8 months because the activities don’t make sense or weren’t giving any results.

In 2025 and going into 2026, this decision is becoming more critical than ever as buyer journeys fragment, AI accelerates execution, and positioning becomes harder to reverse once it is live in the market.

As a founder of Groie, a product marketing studio, this article is more about sharing my experience on when it is the right fit to hire your first “founding marketer” or when to opt for an agency.

Why SaaS Product Marketing Is No Longer Optional

SaaS product marketing used to be associated with launches and messaging decks. That era is over. Today, product marketing sits at the intersection of ICP clarity, category narrative, content strategy, outbound relevance, sales enablement, and product adoption.

April Dunford, positioning expert and author of Obviously Awesome, puts it simply: “Great positioning does not come from inside the product. It comes from understanding how the market sees alternatives.”

In 2025, markets were already crowded by default. AI has made feature parity easier and differentiation harder. By 2026, founders are competing less on what their product does and more on how clearly buyers understand why it exists.

This is why SaaS product marketing decisions early on carry long-term consequences.

The Core Question Founders Actually Need to Ask

Most founders frame the decision as: Should I hire an agency or my first product marketer?

The better question is: Do I need clarity, speed, and pattern recognition, or ownership, depth, and continuity right now?

What does that mean? 

Let me simplify. Ask yourself, “Do you need a bunch of experts who can handle design, development, get things live fast, and run campaigns, or do you need someone who builds everything from scratch, focuses on getting things right, and builds momentum single-handedly?”

Those are two different needs. They should not be solved with the same answer.

Hiring Your First Product Marketing Manager In-House or hiring your ‘founding marketer’ 

Bringing your first product marketing hire in-house sounds like the logical next step. Ownership feels safe. Alignment feels natural. Control feels reassuring. And sometimes, it is the right move.

When an In-House Product Marketing Hire Makes Sense

Getting someone inhouse or your founding marketer makes sense when: 

• You have a stable ICP and repeatable sales motion
• Your product direction is unlikely to pivot materially
• Sales feedback loops already exist
• You can support this hire with leadership time and context
• You are ready to commit for 12 to 18 months
  
  

What does that mean? 

You don’t want sporadic marketing activities. Your founding marketer should not spend most of their time designing in Canva just because the social posts calendar demands it, especially when there is no design team to support those needs. They should not be learning development simply because a few pages need to go live, or worse, working on sales only because getting leads feels urgent.

All of these tasks are important and do require involvement, but hiring your first product marketing marketer without a system in place sets them up for failure.

In-house product marketers thrive when they can go deep, build internal trust, and evolve strategy over time. As Dave Kellogg, former SVP at Marketo, has said:
“Hiring too early or too late is equally dangerous. The timing has to match your company’s operational maturity.”

The Hidden Risks of Hiring Too Early

This is where many seed and early Series A founders misstep.

Common risks include:

• Hiring for execution before clarity exists
• Expecting one hire to define positioning, build GTM, create content, design, enable sales, and analyze markets
• Locking in messaging that is not market-validated
• Losing months onboarding someone without a clear mandate
  
  

A single early hire often inherits founder bias. Without external perspective, early messaging hardens too soon. Reversing it later becomes expensive. This is one of the most common reasons SaaS startups stall after initial traction.

Working With a Product Marketing Agency for SaaS

Agencies often get dismissed as execution arms. That assumption is outdated.

Modern SaaS product marketing agencies like Groie operate as pattern libraries. They see dozens of markets, ICPs, failed launches, successful pivots, and messaging experiments across stages.

When an Agency Is the Better First Move

An agency is usually the right choice when:

• You are pre-seed to early Series A
• Your ICP is still evolving
• Your sales cycle is inconsistent
• You need fast clarity more than long-term ownership
• You want to avoid committing to the wrong narrative
  
  

In 2026, speed to insight matters more than speed to output. Agencies that specialize in SaaS product marketing help founders:

• Pressure-test positioning before it ossifies
• Align product, content, outbound, and website messaging
• Create a GTM foundation that an internal hire can inherit cleanly
• Avoid the “rewrite everything in six months” problem
  
  

As OpenView’s 2025 SaaS Benchmarks highlighted, companies that invested in positioning and messaging before scaling headcount saw higher pipeline efficiency and shorter sales cycles.

‍

Why This Decision Was Harder in 2025 and Will be in 2026

Three trends are changing the stakes.

1. AI Has Compressed Execution Timelines

AI tools have reduced the cost of output, not thinking.

This means founders who rush execution without clarity now fail faster and louder. Product marketing errors propagate instantly across websites, outbound, ads, and sales decks.

2. Buyers Expect Narrative Clarity

By 2026, buyers will rely more on self-serve research, AI summaries, and peer validation.

If your SaaS positioning is unclear, no sales call will save it.

3. Product Marketing Is Becoming Cross-Functional by Default

The modern product marketer touches SEO, AEO, content strategy, sales enablement, onboarding, and lifecycle messaging.

Hiring one person too early to do all of that is unrealistic.

How Founders Should Actually Manage This Decision

The smartest SaaS founders treat this as a phased strategy, not a binary choice.

Phase 1: External Clarity and Foundation

At this stage, founders need:

• ICP hierarchy and buyer language
• Category narrative and positioning
• Messaging architecture across channels
• GTM alignment before scale
  
  

This is where a specialized SaaS product marketing partner adds disproportionate value. This is also where Groie operates. Groie works with early-stage SaaS teams to build product marketing foundations that are lean, validated, and scalable. Not campaigns. Not vanity content. Foundations that future hires can build on without rewriting history.

Phase 2: Internal Ownership and Scale

Once clarity exists, hiring in-house makes sense. The internal product marketer inherits:

• A clear narrative
• Proven messaging
• Documented GTM logic
• Defined priorities
  
  

This reduces ramp time and increases the odds that the hire succeeds. In this model, agencies and in-house are not competitors. They are sequential tools.

‍

Agency vs In-House Is the Wrong Framing

The right framing is timing. Hire in-house too early, and you risk locking in the wrong story. Wait too long, and you create dependency. Founders who win in 2026 will be the ones who treat SaaS product marketing as infrastructure, not headcount.

FAQs

Should SaaS startups hire an agency or a full-time product marketer first?

Most seed and early Series A SaaS startups benefit from working with a specialized product marketing agency first to establish clarity before making a long-term hire.

When does hiring an in-house product marketer make sense?

Hiring in-house makes sense once ICP, positioning, and GTM foundations are stable and the company is ready to scale execution consistently.

What are the risks of hiring product marketing too early?

Early hires often inherit founder bias, lack market validation, and get spread too thin, leading to unclear messaging and rework later.

Can agencies replace in-house product marketing teams?

Agencies should not replace internal teams long-term. They are most effective at early clarity, validation, and foundation building.

How should founders evaluate this decision at seed or Series A?

Founders should evaluate market clarity, sales consistency, internal bandwidth, and risk tolerance before deciding. The goal is not speed. The goal is correct sequencing.
