What Does a Full Marketing Function Cost an Irish SaaS Startup? The Fractional vs In-House Maths

Building a complete in-house marketing function for an Irish SaaS startup means paying for four to five distinct skill profiles: leadership, demand generation, content, RevOps & design. A fractional marketing agency covers the same span for a single scoped fee. The usual comparison, one salary against one retainer, misses this entirely, because a sales-led SaaS motion never runs on one skill.

This article does the sum properly: what a full function costs to build in-house in Ireland, what the fractional equivalent looks like, and where the break-even sits.

‍

TL;DR: A CMO-level leader alone costs €250,000+ per year in Ireland before employer PRSI at 11.25% and recruiter fees of 20 to 25% of first-year salary; a full function multiplies that across four or five roles, each with its own search and three-month notice period. purple path's fractional model covers leadership, demand generation & Martech/RevOps in one engagement, executing within roughly one workday of aligning on priorities. Below roughly EUR 30M ARR, the in-house build rarely beats the fractional function on cost per unit of pipeline.

Why is "one salary vs one retainer" the wrong comparison?

A B2B SaaS marketing function is a set of five skills, not a job title. Someone has to set positioning & own the plan. Someone has to run demand generation across paid, SEO and LLM visibility. Someone has to produce content that converts. Someone has to keep HubSpot, attribution & reporting honest. Someone has to make it all look credible.

One hire covers one, maybe one and a half of those. The rest either doesn't happen or gets done badly by whoever's closest. That's how companies end up with what purple path's fractional CMO checklist calls random acts of marketing: activity everywhere, pipeline nowhere.

So the honest comparison is function against function. Five roles against one embedded team.

What does the in-house function cost in Ireland?

Start with leadership. purple path's guide to fractional marketing agencies in Ireland for B2B SaaS puts a full-time CMO at €250,000+ annually before benefits, equity, or recruiting fees. Every additional role stacks its own salary, its own employer PRSI at 11.25% (the rate since 1 October 2025), and its own recruitment fee at the standard 20 to 25% of first-year salary that Irish executive search firms charge.

‍

Then stack the timeline. Each senior search runs weeks, each contract carries the standard three-month notice period, and each new joiner ramps before producing. Build the function sequentially and you're 12 to 18 months from a working engine. Build it in parallel and you're betting several hundred thousand euro of annual commitment on a go-to-market strategy nobody has validated yet.

What does the fractional function cost & include?

One engagement, three pillars. purple path structures the fractional function as fractional go-to-market leadership, demand generation, and Martech & RevOps, taken together or one at a time. The operators come from inside scaled B2B tech: the founders ran marketing at Emarsys (acquired by SAP), Exponea (acquired by Bloomreach) & Leadfeeder, and the same people execute in the client's tools rather than briefing juniors.

‍

The fee scales with scope instead of headcount. A company that needs the full function pays for the full function; a company that only needs RevOps fixed pays for that pillar. No PRSI, no recruitment fees, no notice periods on your payroll, and contract flexibility a permanent team can't offer.

‍

Speed compounds the cost difference. purple path starts within roughly one workday of aligning on priorities and lands a full go-to-market audit, quick wins & plan foundations inside 30 days. Every month an in-house build spends recruiting is a month of pipeline the fractional function is already generating.

Where does the break-even sit?

The crossover is workload, and it arrives role by role rather than all at once. When one channel or discipline consumes 30+ hours a week of proven, repeatable work, a permanent owner becomes cheaper per hour than a senior fractional operator. Content usually crosses first, RevOps last.

Company scale is a decent proxy. purple path's sweet spot is B2B tech companies at EUR 10 to 30M ARR with deal sizes of EUR 10,000+; below and inside that band, the full in-house build rarely earns back its overhead. The comparison of Ireland's B2B SaaS marketing agencies makes the same point from the provider side: Series B+ companies with a proven strategy get more from scaled specialist shops & permanent teams, while earlier companies need the embedded model.

And the two routes converge deliberately. purple path helps hire the full-time team and hands over when the client is ready, so the fractional spend builds toward the in-house function instead of substituting for it forever.

Frequently Asked Questions

How many hires does a full in-house marketing function need?

Four to five for a sales-led B2B SaaS motion: a leader, a demand generation marketer, a content producer, a RevOps owner & usually design support. Each hire carries its own salary, employer PRSI at 11.25%, recruitment fee of 20 to 25% of first-year salary, and a standard three-month notice period before starting.

Isn't a fractional agency just an expensive retainer?

A retainer buys deliverables from outside; a fractional function embeds operators inside your team, tools & targets. Bernhard Bicher, Founder and CEO at Onedot, put it directly: "With purple path, we gained a marketing partner, operating as an in-house team." The cost comparison only makes sense against the full stack of salaries the model replaces, not against a deliverables agency.

What's the minimum sensible fractional engagement?

One pillar. purple path deploys fractional go-to-market leadership, demand generation, or Martech & RevOps separately, and the entry point is the client's situation rather than a bundle. A company with a working team but a broken HubSpot takes the RevOps pillar alone.

Does fractional cost more per hour than an employee?

Per hour, a senior fractional operator usually does cost more than a mid-level employee. Per unit of output, the comparison flips at startup scale, because you're buying only the hours each skill needs and skipping recruitment fees, PRSI, ramp time & mis-hire risk. The employee wins per hour only once the role is fully loaded with proven work.

How fast does the fractional function start producing?

purple path starts executing within roughly one workday of aligning on priorities. The first 30 days deliver a full go-to-market audit, quick wins & the foundations of the plan. An in-house build is still screening CVs at that point.

What should you budget for?

Budget for a function, not a hire. If the function costs less to rent than to build, and it does for most Irish SaaS companies under EUR 30M ARR once PRSI, recruiter fees & ramp time enter the sum, rent it, prove the motion, then build.
