In-house, agency, or
digital partner?
The B2B model NZ scaleups should use.

Every B2B founder hits this wall eventually. The product is working, sales are coming in, and suddenly marketing matters. The question is never "should we do marketing" - it's who does it, how, and how much it costs before you actually know if it's working.

Why this decision breaks companies

Most B2B companies get this decision wrong not because they chose the wrong model, but because they chose it at the wrong time. They hire a full-time marketing manager at Series A when they haven't validated a single channel. Or they sign a 12-month agency retainer when they're still figuring out ICP. Or they try to do it themselves with a founder who hates writing.

The decision isn't permanent, but it's expensive to undo. A bad hire takes 6–12 months to realise and 3 months' notice to exit. A bad agency retainer bleeds $5k–$15k/month while you wait to see results that never come. Getting this right at the right stage is one of the higher-leverage decisions a founder makes in years 1–3.

The three models, actually explained

There are three real options. Everyone already knows their names - in-house, agency, digital partner - but they get described in ways that suit whoever's selling them. Here's what they actually mean in practice.

In-house: what you actually get

An in-house marketer is someone on your payroll, usually a Marketing Manager or Head of Marketing at seed/Series A, who owns a mix of content, campaigns, CRM, sales support, and reporting. They know your product, they're in the room when strategy changes, and they care about the outcome because their job depends on it.

The catch: a good one costs $90k–$130k+ in NZ (more in AU/US), and they usually have one or two deep skills and a lot of surface-level everything else. You're paying salary, benefits, and onboarding for someone who needs 2–3 months to ramp before they're producing anything. And if they leave, you start from scratch.

• Works best when: you have product-market fit, a validated channel, and enough predictable revenue to justify a 12-month salary commitment
• Breaks down when: you're pre-PMF, the ICP is still fuzzy, or the founder expects one person to do six different specialisms at senior level
• Often missed: junior hires become project managers, not producers. They manage agencies, brief designers, and run reporting - they rarely do the work themselves

Agency: what you actually get

Agencies sell scale, process, and specialisation. The pitch is that you're getting a whole team - strategist, writer, SEO lead, designer - for the price of one hire. On paper, that sounds like good math.

In practice: you get a senior person in the pitch room and a junior account manager once the contract is signed. The team rotates. Your brand context lives in a shared Google Doc that gets skimmed at the start of every sprint. Reporting optimises for vanity metrics because those are easier to defend. And the retainer auto-renews while results stay flat.

There are genuinely excellent agencies. But they tend to work best for companies that already know what they want - where the strategy is set and the execution needs firepower, not direction. That's usually post-Series B, not seed.

• Works best when: strategy is set, channels are proven, and you need volume output at specialist skill level
• Breaks down when: you need strategic thinking, are still discovering what works, or have a brand that requires deep context to represent well
• Often missed: agencies are production engines, not strategy partners. Expecting strategy from a production engine is where most relationships go wrong

Digital partner: what you actually get

A digital partner - sometimes called a fractional CMO, embedded operator, or growth partner - is somewhere in the middle. You're not hiring an employee, and you're not getting a production agency. You're getting an experienced operator who works across your business at the strategic and execution level, usually with fewer process layers than an agency and more skin in the game than a contractor.

The key differentiator is accountability. A good digital partner ties their output to pipeline, not to deliverables. They don't invoice for a monthly content calendar - they measure whether the content moved the number.

This model scales up or down. It works especially well for founders who need a marketing brain without a full-time hire, or for companies going through a specific phase (launch, funding round, new ICP) where a generalist operator outperforms a specialist agency.

• Works best when: you need strategy and execution combined, you're in a growth or transition phase, and a long-term hire isn't the right call yet
• Breaks down when: you need volume content output, large-scale paid campaigns, or a clearly scoped specialist skill at scale
• Often missed: annual prepay or pipeline-tied retainers align incentives in a way a day rate never can - the partner has skin in the outcome, not just the hours

The honest comparison

Here's the same decision laid flat. No pitch decks, no positioning. Just what each model actually costs and what you're actually getting for it.

The stage question

Stage matters more than budget. The right model at seed is usually wrong at Series B, and vice versa. Most founders over-hire for their stage or under-commit for their goals. Here's a rough decision map.

Pre-seed and seed

At this stage, the best thing you can do is figure out what works - not scale what you think should work. That means moving fast, testing channels, killing what doesn't move, and doubling down on what does. A large agency retainer is almost always the wrong call here. You don't have enough signal to brief them well, and they don't have enough incentive to find it for you.

A digital partner or the founder doing marketing themselves tends to outperform at this stage. The founder knows the product and the customer better than anyone. A good operator can run experiments fast without process overhead. The goal is signal, not scale.

Series A to early Series B

Here is where the model question gets complicated. You probably have some channel validation. You have ARR. Investors want to see marketing as a growth lever. The temptation is to hire a Head of Marketing and let them "build the function."

The problem: a newly-hired Head of Marketing at Series A spends the first 3 months doing discovery, the next 3 building a plan, and the next 3 starting to execute. You're 9 months in before you see anything meaningful. Meanwhile, your competitors who started earlier are already compounding.

A better approach at Series A: bring in a digital partner or fractional operator to run and prove the strategy first. Then hire to the proven model, not to an idea of what the model should be.

Post-Series B and beyond

At this stage, you need a real marketing function. In-house leadership with a clear org structure, and agencies for specialist execution volume. A digital partner still has a role - often running specific projects like a product launch, entering a new market, or building out a content engine - but the core function should be internal.

The agency dynamic shifts here too. You now have the strategy, the channels, and the context to brief an agency properly. They become a production partner rather than a strategy substitute, which is where they perform best.

When operator-led wins

The model I work with - digital partner, embedded operator - wins most often in the following scenarios. I'm being direct here because it's not for everyone, and I'll tell you straight if it isn't.

• You're pre-hire: need strategy and output before you've got the ARR to justify a salary
• You're post-bad-agency: had a retainer that produced content but no pipeline, and you need to rebuild with accountability
• You're in a specific phase: fundraising, launching, entering a new market - phases that need fast, strategic execution, not a 12-month plan
• You need senior skill set without senior price tag: 12+ years of B2B experience for a fraction of what a full-time hire costs, with no onboarding tax
• Cash is constrained: equity-for-marketing arrangements work here, and align incentives in a way that day rates never can

The decision framework

Here's the actual decision tree. Not a Miro diagram, just the logic.

1. Do you know what channel is working? If no: digital partner or founder-led. If yes: proceed to 2.
2. Do you have ARR to justify a $100k+ salary? If no: digital partner, fractional, or operator model. If yes: proceed to 3.
3. Is strategy set or do you need it built? If building: operator/partner first, hire to the model second. If set: hire in-house and use agencies for volume execution.
4. Is speed critical? Agency ramps in 4–6 weeks with process overhead. An experienced operator can start producing in week one.
5. What's the real accountability model? If you need results tied to pipeline, not deliverables, a partner arrangement beats both agency and junior hire.

What I actually do

Cut the Waffle sits firmly in the digital partner model. I work with B2B companies - mostly SaaS and scaleups - at the strategy and execution level. One call, then the work starts. No 47-page proposals, no account manager, no six-week onboarding. Direct line to the operator who's also currently running a B2B marketing function full-time, so the playbooks are live, not theoretical.

For B2B SaaS scaleups and established B2B companies, it's either a fixed-scope project (Foundation or Full Package) or an ongoing partner retainer tied to pipeline metrics. Annual prepay gets 10% off the headline rate.

If the agency or in-house route is the right call for you, I'll say so. This isn't a sales page dressed as advice. But if you've read this far and recognise your own situation in any of the above, the next step is simple.
