You're the only marketer in the building — SEO, content, paid, the website, and the board deck all land on your desk.
ON-SITE MARKETING MANAGER FOR B2B
The senior marketing manager you need — without the hire.
Growston embeds a dedicated marketing manager into your business — owning the roadmap, running the specialists, and reporting straight to you — backed by the SEO, paid, content, and engineering bench most solo marketers never get to use.

The situation
You’re doing the marketing manager’s job on top of your own.
You have a website, a content calendar, maybe a few campaigns running. None of it has a senior owner.
The day fills with approvals, ad hoc requests, and fires. The 30/60/90 plan you meant to write stays a draft.
A designer here, a contractor there — nobody owns the outcome, and you're the project manager by default.
More pipeline, more content, more brand — with the same headcount and no senior marketing leader in the room.
A junior marketing hire needed months of ramp-up and management you didn't have time to give.
You need senior judgment running marketing day to day — not a board-level hire you can't justify this year.
Why Growston
Most staffing options give you a person. We give you a person with a team behind them.
A freelancer or a solo hire can run one channel. They can't run SEO, paid, content, and the website as one system — because that takes a bench, not a single set of hands. Growston's Outsourced Teams model pairs the embedded manager with the specialist bench that stays plugged into your workflow.
A typical hire or freelancer
- A full-time hire runs €80K–€150K/yr in salary, benefits, and recruiting (estimate) — before ramp-up time
- A freelancer runs their own calendar and disappears when a bigger client calls
- A generalist hire has to learn SEO, paid, content, and web from scratch — or outsource it anyway
- Junior hires and freelancers report on activity: posts published, tasks closed
- If it's not working, you're managing a difficult exit, notice periods, and a re-hire
Growston
- A senior embedded manager, live in weeks, at a fraction of full-time cost — with no severance risk if the fit isn't right
- A dedicated manager, in your Slack and your CRM, on your cadence — embedded delivery is the model, not the exception
- Your manager has Growston's specialist bench behind them — SEO/GEO, paid, content, and development — the same day the plan calls for it
- Your manager is accountable to the same commercial metrics the board asks about — pipeline, MRR, CAC payback — not a task list
- If it's not working, we name it first — and the engagement ends professionally, no severance, no drama
What we do
One manager, running the whole system
Growston’s On-Site Marketing Manager service embeds a senior marketing manager into your business to own the roadmap and coordinate every specialist behind it — pulled from Growston’s bench the moment the plan calls for them.
Strategy without the deck
Your manager sets the 30/60/90 roadmap and defends it to your board — backed by Growston's Strategic Oversight bench when the plan needs a fractional CMO's eyes.
One owner for every specialist
SEO, paid, content, and design report to your manager, not to you — pulled from Marketing Team Augmentation the moment the roadmap calls for extra hands.
Reporting your CEO can read
Monthly numbers tied to pipeline and CAC, not activity — built on the same Analytics & Tracking layer every Growston engagement runs on.
Content that doesn't wait on a freelancer
Your manager briefs, reviews, and ships content on schedule, calling in Content Strategy specialists for anything that needs a dedicated writer.
Paid spend with an owner, not a rep
If paid is part of the mix, your manager sets the brief and holds Paid Performance accountable to the same pipeline number as everything else.
Ready when the next market is
If growth means Oslo this year and London next, your manager already speaks the language — with International Expansion behind them when you're ready to move.

Let's meet

How the first meeting works
We do the homework before we meet — so the meeting starts at your numbers.
Before the meeting: We review what's public about your marketingsite, positioning, search visibility — before we meet.
In the meeting: 30 minutes on your growth target, what's missing, and what we'd change. Not a pitch deck.
After: A written proposal within 3 business daysscope, price, and the outcomes we'd commit to. Yours to keep either way.
No marketing function yet? The meeting covers structure, budget bands, and a realistic build timeline.

The alternatives
The honest comparison
| Growston | In-house hire | Big traditional agency | Freelancer / solo fractional CMO | |
|---|---|---|---|---|
| Cost | Fixed-scope, mid-market pricing for one senior manager with a specialist bench behind them | €80K–€150K/yr in salary, benefits, and recruiting (estimate) — before ramp-up | Expensive, and your account gets whoever the agency assigns that month | Affordable, but one person, one channel focus |
| Time to value | Weeks — audit to an embedded manager running your plan | 3–6 months hiring, plus ramp | Slow — briefs handed to juniors, account managers rotate | Fast to start, but capacity caps out fast |
| Strategy + execution together | Yes — one manager owns the plan and the specialist bench that executes it | Depends entirely on who you hire | Rarely — strategy and execution sold as separate retainers | Strategy yes, execution capacity no — they still need hands |
| After launch | Runs, tests, and improves the plan monthly, with a quarterly review | Maintenance mode until the next hire | Account handed to juniors | Unreliable continuity if they move on |
Fit check
Who this is for — and who it isn’t
Not a fit if you:
- Are pre-revenue with no product-market fit yet — there's no plan to manage until there's a product to market
- Already have a senior in-house marketing leader — Marketing Team Augmentation fits better than a second manager
- Operate in crypto, gambling, adult content, or MLM
A strong fit if you:
- Are a B2B SaaS, scale-up, or founder-led company in the Nordics, UK, US, or expanding into them
- Have revenue and budget for marketing but no senior person owning it — the founder, CEO, or a junior hire is currently carrying the load
- Want one accountable manager instead of a stack of freelancers and vendors you have to coordinate yourself
- Are ready to give your manager access to your tools, your data, and your decision-makers so they can actually run the plan

FAQ
Before you ask
What does an On-Site Marketing Manager actually do, day to day?
They own your 30/60/90 roadmap, run the specialists behind it — SEO, paid, content, web — and report straight to you or your board, the way an in-house marketing manager would, without the six-month hiring process.
Is this a full-time hire, a contractor, or something else?
It’s an embedded team member: dedicated to your account, working inside your tools and cadence, backed by Growston’s specialist bench — without the salary, benefits, or severance risk of a direct hire.
How is this different from Marketing Team Augmentation?
Marketing Team Augmentation adds specialist hours to a plan you or your team already own. An On-Site Marketing Manager owns the plan itself — the roadmap, the reporting, and the coordination across every channel.
We already have a junior marketing hire. Does this replace them?
Usually not. The manager gives your junior hire senior direction and a system to execute inside, instead of leaving them to work out strategy alone.
How fast can a manager be running our account?
Typically weeks from the first meeting to an embedded manager working inside your tools, once the audit and 30/60/90 plan are agreed.
What happens if the manager isn't the right fit?
We name it first, in the quarterly review or sooner. If it isn’t working, the engagement ends professionally — no severance, no drama, and you keep everything documented so far.
