AI CEO vs fractional COO for a B2B company under $1M a month

Written by Wanna AI. Updated 17 Oct 2026. Prepared with AI; the quotes about fractional COOs and the numbers about Wanna were read on that date. Wanna is our product and one of the two options compared here.

In short. A fractional COO is an experienced person who runs your operations part-time: the rhythm of the company, the processes, the people who report to you. Wanna OS is an AI that reads your company, proposes the next tasks, and drafts the outside-facing work (letters, posts, applications, a list of fixes for your site) for your OK. They do different jobs. For people and process inside a team, a fractional COO fits. For growth work you have no hands for, try Wanna. Wanna is early: on 17 Oct 2026 it had 3 companies of people and none of them paying.

What a fractional COO does, and what it costs

Three pages that sell or explain the service, read on 17 Oct 2026:

• MentorCruise: a fractional COO works "usually one to three days a week on a monthly retainer" and will "set up the operating rhythm, manage department heads, fix broken processes and own cross-team projects". Its price: "Most fractional COO engagements cost" $7,200 to $10,800 "per month for about 12 hours a week" (MentorCruise).
• Darrigo Consulting (page dated 20 July 2026): "Fractional COO rates typically range from $5,000 to $15,000 per month on a retainer basis", with 10 to 20 "hours per week with each client". It calls the service "typically the right choice for companies between $2M and $30M in revenue" (Darrigo Consulting).
• Size.vc: "Investment typically ranges from" $15,000 to $30,000 "per month for part-time retainer engagements"; the role is a senior operator who works part-time "to design scalable systems" (Size.vc).

The three pages give ranges from $5,000 to $30,000 a month, and each is written by someone who sells the service or its matchmaking. Read them as a range, not a quote.

What Wanna OS does today

Read from how it works and Trust on 17 Oct 2026. You paste your site link. Wanna reads it and your market, proposes the next tasks, and drafts the work: investor letters, launch posts, grant and accelerator applications, ads, a list of fixes for your site. It finds grants, accelerators and investors, each with a source. You pick one of two modes, "Approve everything" or "Autonomous". In both, posts, applications and ads wait for your OK, and sending letters is off for a new company until you turn it on. Money and signatures stay with you.

Where each one fits

This is how we sort them, not a ranking.

What we measured about ourselves (17 Oct 2026, 05:25 UTC, /live)

Companies of people on Wanna: 3. Sign-ups, last 7 days: 2. Tasks done, last 7 days: 18. Things that went outside, last 7 days: 0. Paying companies: 0. MRR: $0. These counts leave out Wanna's own and test companies and are re-counted on every load of the live page.

What Wanna does not replace

Wanna does not replace a COO's judgment about people. It does not manage your staff, run your stand-ups, fix a broken delivery process inside your team, or sit in a negotiation. It does not move your money, sign documents, or write or ship your code. It has no security audit report such as SOC 2 yet; Trust says so. If the pain is a team that does not execute, hire the person. We have no case of such a company running on Wanna.

When to pick which

Pick a fractional COO when the work is inside the company and needs a human who can be held to a result: managers, process, delivery. Pick Wanna when the work is the growth tasks nobody has hands for, and you want to see a plan of cards you approve before anything goes out. The two modes of control are in Approve everything or Autonomous; a different comparison is AI chief of staff vs AI CEO.

FAQ

Is an AI CEO a cheaper fractional COO? No, it is a different job. The pages above describe a fractional COO as a part-time operator of your team and processes. Wanna drafts and plans the outside-facing work and does not manage people.

Can an AI replace a fractional COO for a company under $1M a month? Not for the people and process side, and we have no customer case to show. For letters, posts, applications and a weekly plan, it can take work off your hands, with your approval.

Can I use both? Yes: the COO runs the team, Wanna prepares outside work for your OK.
