The problem

Buyers cannot find straight answers on what fractional marketing leadership should cost.

How a fractional CMO fixes it

Transparent monthly retainers scoped to your stage — typically 30–50% of a full-time CMO for the leadership you need.

What a fractional CMO actually does

Fractional CMO work covers strategy through execution: sharp positioning and messaging, demand generation tied to revenue, the analytics to prove what works, and team building — the right hires, the right stack, and the documented processes that outlast any single person.

How the engagement works

01

Discovery & audit

Weeks 1–2: understand your funnel, goals, data, and the gaps holding growth back — talk to sales, customers, and the numbers.

02

Strategy & plan

Weeks 2–4: lock positioning, choose the channels that fit your motion, and build a 90-day roadmap tied to revenue.

03

Build & execute

Weeks 4–8: install the systems, make or manage the hires, launch the channels, and start producing measurable pipeline.

04

Measure & scale

Weeks 8–12 and on: attribution to revenue, cut what is not working, and double down on what is.

What you get

01

Strategy & positioning

A clear go-to-market and a message that converts — one your whole team can repeat.

02

Demand generation

Channels and campaigns that produce pipeline, measured to revenue instead of clicks.

03

Team & operations

The right hires, tools, and SOPs — a marketing department that runs itself.

04

Analytics & attribution

Honest reporting that ties every dollar of spend back to pipeline and closed revenue.

05

Budget ownership

A marketing budget allocated by someone accountable for the return on it.

06

Executive alignment

Marketing that sales trusts and the board understands — one shared number.

Fractional CMO vs. full-time CMO vs. agency

Weigh the three options and the fractional model stands out. A full-time CMO means dedicated leadership at $250k-plus and a months-long hire. An agency means hands, not ownership — it executes your brief and bills you. A fractional CMO gives you the strategic accountability of an executive, delivered part-time and priced for your stage.

How pricing works

A fractional CMO engagement is a flat monthly retainer, sized to scope and free of equity or long contracts. Companies needing mostly strategy engage fewer days; those needing execution engage more. In practice fractional CMO rates run about 30–50% of full-time CMO comp — senior leadership at a fraction of the full-time price.

Frequently asked questions

What does a fractional CMO do?

A fractional CMO owns your marketing strategy, team, and growth systems on a part-time retainer — positioning, demand generation, analytics, and hiring — with accountability for pipeline and revenue, not just tasks.

How much does a fractional CMO cost?

Typically 30–50% of a full-time CMO salary, on a flexible monthly retainer scoped to your stage. You get C-suite marketing leadership without the $250k+ commitment or the long hiring cycle.

How is a fractional CMO different from an agency or a consultant?

An agency runs tactics and a consultant advises. A fractional CMO takes ownership — sets the strategy, builds and manages the team, and is accountable for the number, operating like a member of your executive team.

How quickly can a fractional CMO start?

Most engagements ramp in about two weeks. You skip the 4–6 month executive search and start making progress on strategy and pipeline almost immediately.

What size company is a fractional CMO right for?

Seed-to-Series-B startups, SaaS companies, and growing B2B firms — typically doing $1M–$50M in revenue — that need senior marketing leadership but cannot yet justify, or do not yet need, a full-time CMO on payroll.

What results should I expect?

A clear go-to-market strategy, marketing that sales trusts, attribution tied to revenue, and a team and system that keeps producing pipeline after the engagement scales down. The aim is a self-sustaining marketing function, not permanent dependence on a consultant.

Fractional CMO vs. full-time CMO — how do I choose?

If you have the budget, workload, and revenue to support a $250k+ executive full-time, hire one. If you need senior leadership now but want to de-risk the decision, a fractional CMO gives you the same caliber of leadership scaled to your stage — and can help recruit your eventual full-time CMO when the time is right.

How many hours or days a month does a fractional CMO work?

It varies by scope. A company that mainly needs strategy and oversight might need a few days a month; one that needs hands-on building needs more. The retainer is sized to the work, and it can flex up or down as your needs change.
