Comparison
Agencies are useful when the strategy is clear and the team needs execution capacity. A fractional CMO is useful when the constraint is diagnosis, priority, system design, and weekly growth decisions — that senior layer is what WSS provides.

Side by side
The right choice depends on whether strategy and priorities are already clear, or whether the company still needs senior judgement to decide what matters before more execution.
| Dimension | Agency | We Scale Startups |
|---|---|---|
| What gets delivered | Channel execution (paid, SEO, content, creative) | A repeatable system the team (and partners) can run |
| Strategy | You brief the channel; they ship | We diagnose the constraint, then align execution |
| Reporting | Often channel metrics and delivery dashboards | Commercial signal, scale, stop, fix calls |
| Decision rights | Strong on their remit | Shared on the outcome across channels |
| When the engagement ends | Delivery pauses with the retainer | The operating rhythm continues without us |
| Founder dependency | You may still own cross-channel calls | You step back as the system owns the cadence |
The third option
Fractional fits when you need the system and cadence without locking in a permanent exec search. Full-time fits when the role is stable and you want a single owner for the next multi-year chapter.
When you need senior GTM judgement and a running system now, but the full-time CMO brief is still evolving — stage, channel mix, or team shape is not stable enough for a £150k hire.
When the constraint map is clear, the weekly cadence runs without the founder, and you want a permanent executive owning vendor strategy, hiring, and board narrative long term.
Often yes. We help define the bar, interview for system-building ability, and hand over dashboards and decision rules so the hire starts with context rather than a blank page.

Before you hire anyone
Agencies execute; they rarely fix cross-channel prioritisation. A first marketing lead inherits whatever system already exists. If the founder still owns every scale/stop/fix call, neither hire solves it.
Each channel reports in its own dashboard, briefs change weekly, and nobody can say what gets scaled or stopped on Monday. A new agency inherits that chaos; it doesn't fix it.
The channel plan is clear, the offer converts, and you need production capacity — more creative, more pages, more campaigns. That's what agencies are built for, and the brief writes itself.
Hiring into an undefined GTM motion produces expensive, frustrated marketers. You want a named bottleneck, a weekly decision cadence, and one internal owner who can receive a system before you recruit into it.
FAQ
Yes. WSS often sits above or alongside an agency: we set priorities, define what good looks like, review signal, and make sure channel execution connects to the commercial outcome.
If you know the channel and only need execution, hire an agency. If you are unsure where growth is breaking, start with diagnosis or WSS fractional leadership before adding more delivery.
Not forever. WSS is usually a bridge: senior growth leadership and system design now, then a cleaner handoff to internal hires or a full-time CMO when the role is clearer.
WSS's Fractional CMO engagement runs £5k–£8k/mo, or £7.5k–£10k/mo for the Plus tier (~2 days/week) — the public ranges are on our pricing page. Many post-PMF startups spend a similar monthly amount on an agency retainer. The difference is what the money buys: an agency retainer buys channel production; a fractional CMO buys senior decision-making, prioritisation, and a growth system your team keeps when the engagement ends.
No. A branding or creative agency delivers identity and production work against a defined creative scope. A fractional CMO owns growth priorities across channels, reporting, and team direction. Many teams need both, in sequence: settle positioning and strategy first, then brief the creative work. If you are choosing where the next pound goes, fund the decision layer before more production.
Usually it is an agency model with more integration: external people working inside your standups and tools. That solves communication, not ownership. The question stays the same — who makes the weekly scale, stop, and fix calls? If that judgement still sits outside the company, or still with the founder, you need a senior owner (fractional or in-house) before more embedded execution.
