AI CMO vs hiring a CMO: an honest comparison

The value of a strong CMO is mostly judgment. Which market to go after first. Which message to stop using. Which channel deserves a budget and which one is a distraction. They sit in meetings with sales and product, hear what customers say, and turn it into a direction that the whole company follows.

They also lead. They hire, coach and keep a team focused, negotiate with agencies and partners, and answer to the board when the numbers are off. None of that is something Toby does, and we don’t pretend otherwise.

Toby covers the part of marketing that has to happen every day. When you sign up, it reads your website and produces a growth audit (SEO checks, conversion checks on your homepage, and a test of how AI assistants answer the questions your buyers ask), then writes your Brand Brain: six documents on your product, ideal customer, competitors, brand voice, marketing strategy and content strategy. Every agent reads them.

From there, Toby, the AI CMO, and the specialists send recommendations. Each one shows why, with the exact evidence it relies on, an estimated impact, the effort, and a first step that is already prepared: the headline options, the email sequence, the ad copy. A quality check rewrites or discards generic ideas before you see them. You click Apply, Later or Dismiss, and Toby learns from your reasons.

What it doesn’t do: manage people, attend your meetings (though it can read notes from Fireflies, tl;dv or Fathom), or make the final call. It can also be wrong, which is why it shows its evidence and waits for your approval before anything goes out.

A full-time CMO is a senior executive. For reference, the US Bureau of Labor Statistics puts the median annual wage of marketing managers at $166,790 (May 2025), and a CMO is usually a more senior role than the median marketing manager. Add employer costs, recruiting time and, often, equity.

A fractional CMO works a few days a month for several companies. Example estimate: if you price a working day at what that median salary represents (about $640 per day over 260 working days) and book two days a week, you reach roughly $5,500 a month, before any premium an independent senior expert adds for flexibility and experience. Real rates vary widely with seniority and scope.

Toby costs $99 a month per company, about $1,188 a year. The comparison is not like for like: you are not buying the same thing. You are buying daily execution and monitoring at a fraction of the cost, and keeping the judgment for yourself or for a human expert.

A fractional CMO has limited hours. Spending them on writing first drafts, pulling numbers from Search Console or checking a blog’s meta descriptions is expensive. With Toby, those hours go to decisions.

In practice: the CMO edits the Brand Brain so every agent works from their positioning. Toby’s weekly report, sent every Monday, becomes the agenda of your call. The CMO approves, adjusts or dismisses recommendations, and Toby prepares the next round. For fractional CMOs who work with several clients, Toby handles multiple companies with data kept separate for each one, at $99 a month per company.

Hire a person when marketing becomes a team to lead rather than a list of tasks: several people to manage, a budget large enough that allocation mistakes are costly, or a market where trust and relationships decide the deals. At that point, Toby doesn’t disappear. It becomes the team’s daily engine, and the CMO gets a brief every morning instead of a blank page.
