The Fractional COO is a set of nine AI agents from Mulkern AI Systems, a Houston company. Each agent takes a short intake about your business and returns a long document, the kind of thing a part-time operations executive might draft. Nothing connects to your systems. That is deliberate, and the vendor says so.
Nautis does almost the reverse. It doesn't write you a 100-day plan on request as a headline feature. It keeps the tasks, cash and deals that such a plan would act on. So the honest comparison is about which gap you have right now, a missing plan or a missing system. Details below come from the vendor's pages, read in October 2026.
Do you have a planning gap or a follow-through gap?
You have a planning gap if nobody has written down the operating cadence, who decides what, or which numbers matter. A good document solves that quickly. The Fractional COO is priced and built for that moment, and its live sample shows a finished 100-day plan for a fictional field-services company without any signup.
You have a follow-through gap if the plan exists and nothing happens. The owner forgot, the date passed, nobody noticed. A better document won't help. You need the work recorded somewhere that raises it each morning, which is what task boards and the Chief of Staff briefing do in Nautis.
Most young companies have both, in that order. That is why these two products can sit together more easily than most on this site.
The nine documents, and the closest thing in Nautis
| Fractional COO agent | What it writes | Closest in Nautis |
|---|---|---|
| Operating Cadence & Governance Blueprint | Meeting rhythm, scorecard cadence, decision rights | No framework. Decision Loop keeps a decision journal, and routines handle recurring prompts |
| SOP & Process Library | Mapped SOPs, RACI, a documentation system | Notes holds what you write, and Documents is a template library. No SOP generator covered in the guides |
| Operating Scorecard & KPI System | 5 to 9 numbers with targets, owners, sources, review cadence | KPI tasks on task boards, with a number against a target |
| Org Design & Accountability Chart | Future org, seats, role clarity | Employee records and roles. No accountability chart |
| Capacity & Workforce Plan | Staffing matched to demand | Jobs and recruitment, and the financial planner for the cost side |
| 100-Day Operations Plan | Bottlenecks, sequenced fixes, owners, milestones | Outcome Workflows turn a stated goal into a step plan and a task board |
| Process Improvement Audit | Value-stream map, the 8 wastes, root causes | Not covered in the guides |
| Strategic Sourcing & Vendor Plan | Spend map, supplier consolidation, savings roadmap | Expenses show spend. No sourcing plan covered in the guides |
| Business Continuity & Risk Plan | Impact analysis, risk register, incident playbooks | Not covered in the guides |
Read that right-hand column honestly. For writing these particular documents, The Fractional COO is the more direct tool. You could ask Commodore or a custom AI advisor to draft something similar, but no Nautis guide promises a rubric-scored deliverable like these.
How a run works, from key to document
- You paste in your license key and your own Anthropic API key. The vendor says getting the key takes about two minutes the first time.
- You answer a focused intake: your situation, the operating pain, your team, your goal and your constraints. You can also pre-fill it from a CSV, Excel file, PDF or scanned image.
- The agent writes section by section, runs a quality check, and scores itself on a 100-point rubric.
- You get a finished document. You can re-run as often as you like on your key, and the vendor tells you to validate it and have the right owners review it, since it isn't legal or professional advice.
The contrast with Nautis is that this happens when you ask, then stops. Nautis keeps running after setup: a briefing each morning at 7:00 am, weekly digests on Mondays, and routines on a schedule or triggered by events.
Two opposite designs for your data
The vendor's position is clean. It keeps your license details and basic usage counts. Your inputs pass through a stateless gateway to Anthropic under your own account, and it says nothing is written to disk, logged or stored. Its data handling page is direct about the limit too: your data does leave your machine to reach Anthropic, it simply isn't retained by Mulkern AI. And because it doesn't connect to Asana, Monday or your ERP, it can't see anything you didn't type in.
Nautis stores your records because that is the job. Your calendar feeds the briefing alongside those records. You sign in on each provider's own screen, connections are per organization, and writes ask for approval by default. The value comes from access, and access is what you are trusting it with.
If your board or a client forbids connecting systems to outside software, the document route is much easier to get approved. If nothing about the business gets typed in twice, the connected route pays back. Decide which matters more to you before looking at features.
What does each cost in a year?
The Fractional COO is sold as an annual license, and Nautis as monthly or yearly plans. Prices below are as of October 2026.
| Option | Yearly price | Seats or members | Extra costs |
|---|---|---|---|
| Fractional COO, single agent | $1,200 | 1 seat | Your Anthropic usage |
| Fractional COO, 3-agent bundle | $3,000 | 1 seat | Your Anthropic usage |
| Fractional COO, full suite | $9,000 | 5 seats, +$2,000 per extra seat | Your Anthropic usage |
| Nautis Launch | $490 | 5 team members | Credits capped at 1,000 a month, with top-ups |
| Nautis Voyage | $990 | 10 team members | Credits capped at 2,000 a month, with top-ups |
| Nautis Fleet | $1,290 | 25 team members | Credits capped at 2,600 a month, with top-ups |
The vendor estimates Anthropic usage at a few cents to a couple of dollars per deliverable, with no markup. One line in its pricing section says every agent is $1,000 a year, while the plan card and FAQ both say $1,200 for a single agent, so we used $1,200. It also offers a 30-day guarantee: if your first deliverable isn't board-ready, email within 30 days for a refund of the license. Nautis gives you 14 days without a card, then charges, as it has no free tier.
Against a part-time operations executive the vendor quotes $8,000 to $20,000 a month, which makes either product look small. Hold on to that thought for the next section.
Will either one replace a fractional COO?
We don't think so, and neither product does the part that makes a good operator valuable. The vendor's homepage lists a monthly retainer as "replaced", and also says you keep the judgment and that every recommendation needs independent validation. We'd go by the second statement.
A person in that seat walks the floor, notices that two managers aren't speaking, and pushes the team to do the uncomfortable thing. A document can tell you what to fix. A briefing can tell you it hasn't been fixed. Neither one can make someone care. We say the same about ourselves: Nautis doesn't replace a human chief of staff or a board. Read chief of staff vs COO if you are working out which role you actually need.
What these tools can do is lower the point at which you need that person, or give them a better starting place when you hire one.
Using both on a 14-person company
Say you run a 14-person agency that keeps missing delivery dates, and you are still approving every small decision yourself.
- Week one, the plan. You license the 100-Day Operations Plan agent, describe the bottlenecks in the intake, and read what comes back. You cut what doesn't fit, because you know your people, and argue with your co-founder about the rest.
- Week two, the record. You turn the surviving actions into Outcome tasks with owners and dates on a Nautis board, and the numbers into KPI tasks. You could also state the goal in Outcome Workflows and edit the plan it proposes.
- After that, the rhythm. Overdue items reach the morning briefing. The Decision Loop holds the calls you made and when to review them. Nobody has to remember to open the plan document.
- Day 100. You re-run the agent with what you have learned. That's where a document tool and a live system help each other.
Total first-year software cost in that example is $1,200 plus usage for the agent, and $1,290 for Fleet if all 14 people need access. The harder cost is the time spent fitting a first draft to your company.
Where each one falls short
The Fractional COO
- Output only reflects what you type. The vendor calls every deliverable a first draft.
- Its data page says nothing you enter is retained on its side, and reminders aren't listed on the pages we read.
- You need an Anthropic account and API key, which the vendor says takes about two minutes to set up.
Nautis
- It won't teach you an operating method. There is no EOS or OKR framework built in, and no rubric-scored operations plan.
- It needs data before it helps, and approvals take attention.
- It is young, publicly launched in July 2026, with few independent reviews.
Which to buy first
- Buy The Fractional COO first if you have never written down how the company runs, your data can't go into connected tools, or you are an advisor who hands this kind of document to clients. The vendor names fractional COOs and advisory firms as an audience.
- Buy Nautis first if you are a startup founder whose plans are fine but whose follow-through and records aren't, or if fundraising and runway are the pressing concern. Start with the startup operators page.
- Buy neither if you can get an hour with an experienced operator. For a company under ten people, that conversation may beat both.
FAQ
What is the difference in Nautis vs The Fractional COO?
The Fractional COO writes operations documents such as a 100-day plan or KPI scorecard from an intake you fill in, on your own Anthropic key. Nautis is a daily workspace for a startup's tasks, finance, sales and investors, with an AI Chief of Staff. The first gives you the plan and the second keeps the work moving.
How much does The Fractional COO cost?
As of October 2026, a single agent is $1,200 a year, a 3-agent bundle is $3,000, and the full 9-agent suite with 5 seats is $9,000. You also pay your own Anthropic usage, which the vendor puts at a few cents to a couple of dollars per deliverable.
Does The Fractional COO connect to my tools?
No, and its FAQ says that is intentional. You bring the context through an intake or an imported file, and it produces documents. Its stated reason is keeping your data private.
Can Nautis write a 100-day operations plan?
Outcome Workflows can take a goal and propose an ordered plan of about 5 to 9 steps, which becomes a task board. You could also ask the chat to draft a document. Neither is the same as a long, rubric-scored operations plan, so use a dedicated tool or an operator if that document is what you need.
