Structure your marketing team around the jobs your growth depends on now, not around an org chart from a larger company. At Seed that is usually one person who can both plan and do. By Series B it is a small team where every channel that brings in pipeline has a named owner, and one leader is accountable for the number.

The mistake I see most often is hiring for titles before deciding the jobs. A “Head of Growth” hired before anyone knows which motion works ends up doing a bit of everything and owning nothing. The order below starts with the jobs, then fits people to them.

Why structure matters more than headcount

A small team with clear owners beats a larger team with blurred ones. When two people share a channel, neither is accountable for its results. When nobody owns a job, such as lifecycle email or pricing pages, it quietly doesn’t happen, and the gap shows up months later as a conversion problem.

Structure also decides what the founder must still do. Every job without an owner falls back to the founder, usually at night. A good structure frees the founder from execution while keeping them close to positioning, which stays their job longer than any other.

Finally, structure shapes hiring. A role defined by its jobs and outcomes attracts people who have done that work. A role defined by a title attracts people who have held the title. At a startup, the first group is the one you need.

The framework at a glance

This guide works through five steps:

1. List the six jobs, and which matter for the next two quarters.
2. Hire a builder for the job that limits growth most.
3. Add an owner per working channel, then one leader for the number.
4. Decide what stays in-house and what you buy.
5. Write job descriptions around outcomes.

The team shape that results changes by stage. Figure 3 shows the typical shape at Seed, Series A and Series B.

Step 1: List the jobs before you list the roles

Every startup marketing function does some mix of six jobs. Write down which ones matter for the next two quarters, and who does each today, even if the answer is “the founder, badly”.

Example Co., step 1 Fictional

Example Co. sells scheduling software to clinics, has 40 customers and one salesperson. The founder writes all the content and runs a small Google Ads budget. Positioning is clear, demand capture works, and lifecycle is the gap: 300 trial sign-ups a quarter, 9 customers. The first job to staff is lifecycle and conversion, not “brand”.

Step 2: Make the first hire a builder, not a manager

Your first marketing hire should own one or two of the six jobs end to end and do the work themselves. A director who expects to hire a team before shipping anything is the wrong first hire at Seed, in my view, however strong their CV.

Pick the profile from the job you named in Step 1:

• Demand creation or capture is the gap: a growth marketer who has run paid and content with a small budget, and can show the numbers they moved.
• Sales says the story doesn’t land: a product marketer who has written positioning, launch plans and sales material.
• The founder still has to own pipeline: a fractional head of marketing for the strategy, plus a freelancer or junior marketer for execution.

My post on your first marketing hire covers when to hire and how to test candidates on evidence. The First Marketing Hire Kit has the scorecard and the 30-60-90 plan.

Step 3: Add owners by channel, then one leader for the number

Once one or two channels reliably produce pipeline, give each of them an owner. After that, hire the person who owns the whole number: pipeline or revenue from marketing, against a budget.

This is roughly the order I’d follow. The headcounts are illustrative, not a benchmark: there is no reliable public data on startup marketing team size by stage, and teams vary widely by motion.

Example Co., step 3 Fictional

A year later, lifecycle emails have lifted trial-to-paid from 3% to 6%, and Google Ads now brings half of new trials. Example Co. hires a paid acquisition owner and makes the first hire head of growth. The founder stops running campaigns but still owns positioning.

How a large company names its marketing teams Real example

GitLab, a public software company, publishes its marketing handbook. As of November 5, 2026, its index listed separate teams and handbooks for demand generation, growth marketing, marketing operations, product and solution marketing, analyst relations, corporate communications, developer relations, partner and industry marketing, regional marketing and public-sector go-to-market.^[1] That’s what the three groups in Figure 3 grow into at scale. A Series B startup needs owners for the few jobs that matter now, not all of these teams.

Step 4: Decide what to keep in-house and what to buy

Keep in-house the jobs that hold your knowledge of the customer: positioning, product marketing and the analytics that tell you what works. Buy the jobs that need specialist skill in short bursts: design, video, paid-media setup, SEO audits, PR for a launch.

A fractional leader is a reasonable bridge when you need senior judgment for 10 to 20 hours a week, not a full-time manager. My comparison of fractional and in-house marketing leadership covers the trade-offs at each stage, and the cost guide covers the rates.

Step 5: Write job descriptions around outcomes

A good startup job description says what the person will own, what success looks like at six and twelve months, and what evidence you want to see. A list of tools and years of experience doesn’t tell a candidate what the job is. Three templates follow. Change the numbers to your own.

Head of Growth (Series A)

You’ll own: new pipeline from marketing, and the budget and channels behind it.

In your first six months you will:

• Find which two channels can reliably bring qualified pipeline at a cost per customer that pays back within [your payback target].
• Set up the reporting that shows pipeline by channel, which the board and the sales team both trust.
• Hire or brief the first channel owner or agency.

You might be a fit if you have:

• Grown pipeline or revenue at a startup at a similar stage, and can show the before and after.
• Run paid and organic channels yourself, not only managed people who did.
• Written a budget plan and defended it to a founder or a CFO.

Product Marketing Manager (Seed to Series A)

You’ll own: how we explain the product, and the material sales and customers use to decide.

In your first six months you will:

• Rewrite positioning and the homepage from customer interviews.
• Ship the launch plan for [the next release].
• Build the first set of case studies, battlecards and a pricing page sales can use.

You might be a fit if you have:

• Written positioning that changed what a company said, and can show the before and after.
• Run customer interviews and turned them into messaging.
• Worked closely with sales and product.

Demand Generation Manager (Series A to B)

You’ll own: qualified leads and pipeline from [the channels you name], against a target and a budget.

In your first six months you will:

• Take over [channels] and report weekly on cost per qualified lead and pipeline created.
• Run at least [number] tests a quarter and write down what each one taught us.
• Agree the definition of a qualified lead and the follow-up time with sales.

You might be a fit if you have:

• Owned a pipeline target and a budget.
• Run campaigns in the channels above yourself.
• Worked from a CRM and know where its data goes wrong.

Common mistakes

• Hiring a VP to find the first channel. A senior leader expects a team and a working motion to manage. Without either, they spend the first six months building what a builder would have built, at twice the cost.
• Splitting one channel between two people. Shared ownership means no ownership. Give every channel one name and one number.
• Outsourcing positioning. An agency can sharpen your words, but it can’t know your customers as well as you do. Keep positioning with the founder or a product marketer.
• Hiring for tools. “Five years of HubSpot” describes software, not results. Ask for evidence of what the person changed.
• Adding headcount before fixing conversion. More marketers pushing traffic into a leaky funnel make the leak bigger. Fix lifecycle and conversion before you scale acquisition.
• No one owning the data. When marketing ops is everyone’s side job, the board deck and the CRM disagree. Name an owner by Series A.

A checklist before your next marketing hire

• I’ve written down which of the six jobs matter for the next two quarters.
• I know which single job limits growth most right now.
• The role owns that job end to end, with a number.
• I’ve written what success looks like at six and twelve months.
• I know what evidence I’ll ask candidates for, such as a work sample, before-and-after results or a test task.
• I’ve decided what stays with me (usually positioning) and what moves to the hire.
• I’ve budgeted for the tools and the freelance help the role will need.

How to tell whether the structure is working

Check these every quarter:

• Every channel has one owner and one number, and each owner can say whether they hit it.
• Pipeline from marketing is predictable, within a reasonable range of plan for two or three quarters running.
• The founder’s marketing time is falling, except for positioning and key customer conversations.
• Sales and marketing agree on the numbers: one definition of a qualified lead, one source of truth.
• Hiring follows the bottleneck: the next role you plan is the job that now limits growth, not the next title on an org chart.

Examples from different fields

The six jobs are the same everywhere, but which one comes first depends on how your buyers buy. These examples are fictional and illustrative.

B2B SaaS selling to mid-market companies. Buyers search for the category and compare vendors on review sites. The first hire is a demand-capture marketer for paid search and review sites. A product marketer for comparison pages and battlecards follows once sales hears the same objections every week.

AI startup with a usage-based product. Developers try it before anyone buys. The first hire is a technical content or developer-relations marketer who writes tutorials and sample apps. Lifecycle marketing comes next, to turn free usage into paid accounts. Product marketing owns the trust material buyers ask for: how models are evaluated, where data goes, and what changes when the model does.

EdTech company selling to school districts. Buying follows the school-year calendar, and teachers influence administrators. The first hire is a marketer who can run teacher community and events around the planning season. A sales-enablement owner for proposals and pilots follows. My EdTech marketing calendar shows when each job peaks.

MedTech company selling a device to hospitals. Clinical evidence and value-analysis committees decide. The first hire is a product marketer with clinical or scientific credibility. Every claim goes through regulatory review, so marketing operations includes a claims-approval process from day one. The MedTech Marketing Playbook covers the buying committee.

Consumer subscription app. Growth depends on paid social, app stores and retention. The first hire is a performance marketer with creative-testing experience. A lifecycle marketer follows quickly, because retention decides whether paid acquisition pays back.

Two-sided marketplace. Each side needs its own owner: one for supply (sellers or providers) and one for demand (buyers). The first hire usually owns the harder side, which is most often supply.

What changes by stage?

• Seed — One builder, the founder owns positioning and the number.
• Series A — A leader who owns the number, plus channel owners for what already works.
• Series B — A VP with demand, product marketing and operations under them; add regional or segment roles only once one motion works in one market.
