How to Hire a Fractional CMO Who Can Drive Growth

Why Hiring a Fractional CMO Deserves Care

If a company has never had a marketing leader, the first one it brings in will shape how it wins new business for years. This guide by Debra Andrews, Founder and President of Marketri, is written for growth-focused CEOs who are hiring a fractional CMO for the first time. It covers what to look for, what to ask and what to expect once the engagement starts.

The guide starts from a plain problem: "fractional CMO" has become a catch-all title. There is no license, certification or standard behind it, and many people who use it have never held a Chief Marketing Officer role inside a company. A fractional CMO also splits their expertise across several clients, so they have to learn the business quickly and produce results with fewer hours than a full-time executive. That makes real experience in the seat matter more, not less.

Advisory or Embedded: Know Which Model You Are Buying

The guide defines the job in two parts: build the marketing function, and own the results, measured in new clients and new business. It then separates the two ways fractional CMOs tend to work. The advisory model creates the marketing plan and lightly oversees its execution through scheduled check-ins. The embedded model leads marketing as a member of the staff and takes part in leadership meetings, planning sessions and retreats. For a company starting from zero with ambitious growth goals, the guide says the embedded model is usually the right choice. Either way, the candidate's hours and client load have to match what the company needs.

Five Tests and Seven Interview Questions

At the center of the guide are five tests that separate a fractional CMO who can build a marketing function from one who simply holds the title:

1. They have actually been a CMO, inside an organization or across several companies as a fractional leader.
2. They have helped mid-market companies grow, not only large ones that run marketing with deep internal teams.
3. They know your kind of business: B2B or B2C first, then your industry or a related one.
4. Their strengths, brand-focused or demand-focused, match what you need right now.
5. They use AI in their own work and have a plan for using it in yours.

The guide pairs those tests with seven interview questions, each with what to listen for and when to be cautious. They range from a request for a detailed case study at a similar company, to what the first 90 days would look like, to a plan that did not work and what the candidate changed.

What the First 90 Days Should Produce

The guide sets a clear standard for the start of an engagement. By day 90, a CEO should have four things: messaging and positioning that are ready to use, a go-to-market plan built on the company's goals, a clear map of who does the work, and measures that show progress quarter by quarter. It also lists warning signs, such as reports that describe activity but say nothing about progress toward new business, or a CEO who is still the one driving marketing decisions.

How Much to Budget for Marketing

A section on budget lays out benchmarks from Gartner, The CMO Survey and the Hinge Research Institute. The CMO Survey's 2026 edition puts B2B services companies at 10.1% of revenue. For a company building marketing from scratch, the guide suggests planning for 10 to 12% of revenue or more in year one, because early spending creates assets that keep paying off: messaging, branding, website pages, content and sales materials.
