An AI growth agent or a fractional CMO?
A fractional CMO is a senior marketer who works with you a few days a month. Their site
A fractional CMO decides what should happen; Kamu does things. That sounds like a hierarchy and is really a division: the common failure of fractional work is a good strategy nobody has time to execute, and the common failure of Kamu is executing steadily in a direction nobody senior has questioned.
Fractional senior marketers exist because the judgment a company needs is not full-time work but the salary is. You buy a few days a month of someone who has done it before, and what you get is a plan, a set of priorities and someone to tell you when you are wrong.
What you do not get is hands. The recurring complaint about fractional arrangements is not the quality of the thinking, it is that the thinking arrives faster than a small team can act on it. A deck lands, the founder agrees with all of it, and three months later two of nine things have happened.
Kamu is the inverse and just as lopsided. It executes daily and indefinitely without needing anybody's attention, and its strategic thinking is genuinely shallow: it reads your site, works out who plausibly buys this, writes that down, and adjusts toward whatever gets replies. It will never tell you the market is wrong.
So the comparison is not really which is better. It is which half you are missing, and a fair number of founders are missing both.
Side by side
| Kamu | A fractional CMO | |
|---|---|---|
| What you are buying | Execution. Prospects found and written to, articles drafted, posts published, listings filed, daily. | Judgment. Positioning, priorities, channel choice, and someone senior to argue with. |
| How it is priced | From €25 a month. Each plan has its own hard caps and included credits. | A monthly retainer for a set number of days. Most do not publish a rate. |
| What happens between sessions | It keeps working. There are no sessions. | Nothing, unless somebody on your side is executing the plan. |
| Depth of thinking | Shallow and written down. The plan is a document you can read and correct. | The reason to hire one. Years of pattern-matching from companies you have not run. |
| Ramp | First plan on the first run, same day. | A discovery period, then a strategy, then execution by somebody. |
When A fractional CMO is the better choice
Take the fractional CMO when the question in front of you is what to do rather than whether it is getting done. If you cannot say who your buyer is, why they choose you over the obvious alternative, or which channel should work, no amount of daily execution fixes that. It just gets you to the wrong place faster, which is the specific failure Kamu is capable of. Senior judgment is also the thing that stops you spending a year on a channel that was never going to work for your price point, and a good fractional will tell you that in week two.
Questions
Could a fractional CMO direct Kamu?
That is arguably the best arrangement available at this size. Kamu keeps a written strategy you can edit, takes instructions in chat or Slack, and logs every action with its reasoning, so a senior marketer can set the direction and then read what actually happened rather than chasing a founder for updates.
Is Kamu strategic at all?
A little, and it is honest about the limit. It reads your product and market, writes a plan in plain words, keeps every version, and shifts weight toward whatever is getting replies. What it does not do is question the premise. If the positioning is wrong, Kamu will pursue it diligently.
Which should a pre-revenue founder buy first?
Usually the execution, because at that stage the strategy question is often answered by trying things and the constraint is that nobody has time to try them. That is a rule of thumb rather than advice: if you genuinely do not know who buys this, the deck is worth more than the daily sending.
