These two products get compared because both use the phrase business operating system. They mean different things by it. Ninety describes itself as the AI-powered business operating system for companies running on EOS®. Nautis is an AI business operating system for startups, and it has no management method inside it.
So the useful question is what you need software to hold together: a weekly leadership discipline, or the scattered records of a young company. This page goes through features, cost at four team sizes, and how one bad week plays out in each product. Everything about Ninety comes from its own pages, read in October 2026.
Is your company committed to EOS?
If yes, choose an EOS tool and stop here. There is no EOS or OKR tooling in Nautis: no Rocks, no L10 meeting format, no V/TO and no IDS workflow. It won't teach or enforce any framework. You could rebuild pieces by hand on task boards, but you would be fighting the product every week, and your implementer's templates wouldn't fit.
If you haven't chosen a framework, don't let software make that choice for you. Read EOS for startups and EOS vs Scaling Up vs OKRs first, then come back. EOS® is a trademark of EOS Worldwide, and we use the name here only to identify the method.
What each product is built to do
Ninety
Ninety digitizes the tools of a method. Its menu is organised the way EOS is: Vision tools, Data tools, Process tools, Traction tools, Issues tools and People tools. In a Ninety L10, the default agenda pulls in the Scorecard, Rocks, issues and To-Dos, each segment has a timer, attendees rate the meeting from 1 to 10, and people who missed it receive the recap automatically.
Its homepage FAQ says "Ninety is software for systems" and names partner systems besides EOS: Empire, Fireproof and Pinnacle. EOS still dominates the product's language and its pricing page, so expect to work in that vocabulary.
Nautis
Nautis replaces the pile of tools a small company buys one at a time. Task boards, a fundraising CRM, Startup Health for runway, invoices, expenses, a leads CRM, notes, sheets, team chat, data rooms and document signing all sit in one workspace.
The Chief of Staff reads those records and generates a briefing at 7:00 am, grouped as Priorities, Blockers, Approvals, Pipeline, Today and Runway. Anything an agent wants to do waits in the Approval Center unless an owner or admin has switched that capability to Run without asking.
Nautis vs Ninety, feature by feature
| Job | Ninety | Nautis |
|---|---|---|
| Weekly leadership meeting | L10 Meetings with timers, agenda pulled from Scorecard and Rocks, 1 to 10 rating (Essentials and up) | No meeting format. Meetings module handles booking links, calendars and transcripts |
| Quarterly priorities | Rocks with milestones | Task boards with Outcome and KPI tasks, and goals through Outcome Workflows |
| Weekly numbers | Scorecard and KPI tracking | KPI tasks track a number against a target. There is no scorecard view |
| Issue solving | Issues list and IDS | No equivalent method. Board discussion threads and a Decision Loop journal |
| Org design | Accountability Chart, including on the $0 plan | Roles and permissions, plus an employee directory. No accountability chart |
| People reviews | Quarterly and Annual Reviews, People Analyzer (Accelerate and up) | No review module. Burnout Radar is a private wellness check-in |
| AI | Maz answers from your Ninety data and proposes changes you review (Thrive) | Chief of Staff briefing, Commodore chat, advisors, Approval Center |
| Fundraising and cap table | Not listed | Fundraising CRM, investor readiness, deck analyzer. Cap table on Voyage and Fleet |
| Finance records | Not listed | Runway, financial planner, invoices, expenses. Not an accounting system |
| Sales pipeline | Not listed | Leads CRM with custom stages |
| Integrations | Google and Microsoft calendars and tasks, Microsoft Planner, Monday, Zapier, plus Asana, ClickUp and Todoist named on its pricing page | 1,000+ apps through a managed catalog, with writes held for approval by default |
The table shows how little the two overlap. Ninety goes deep on one operating rhythm, and Nautis goes wide across functions that Ninety's pages don't address.
What does each cost for a real team?
Ninety charges per user and Nautis charges per plan, so the gap widens as you add people. These are monthly list prices as of October 2026. Ninety offers 10% off on annual plans, paid upfront, and Nautis yearly plans give 2 months free.
| Team | Ninety Essentials ($12) | Ninety Thrive ($16) | Nautis plan |
|---|---|---|---|
| 5 people | $60 | $80 | Launch, $49 |
| 10 people | $120 | $160 | Voyage, $99 |
| 25 people | $300 | $400 | Fleet, $129 |
| 40 people | $480 | $640 | Above the 25-member cap on Fleet |
Two adjustments matter. Ninety's observers view for free, so a 40-person company might pay for only its managers and direct reports who take part. It also has a $0 plan covering the V/TO, Accountability Chart and assessments, and a 30-day trial of Thrive with no card. Nautis has no such plan, only a 14-day trial with no card.
On the Nautis side, a flat price doesn't mean unlimited use. AI credits are 1,000, 2,000 and 2,600 a month on the three plans. Fleet shared across 25 people works out to 104 credits each, about half what a five-person team gets per head on Launch. When credits run out, sending is blocked until they reset or you top up.
One bad week, handled in each
Picture a 12-person company. Trial signups have missed target two weeks running, and a large customer's invoice is 20 days late.
- In Ninety: the signup measure shows off track on the Scorecard, which the L10 agenda pulls in. Someone drops it on the Issues list, the team works it through with IDS, and the fix leaves the room as a To-Do with an owner. The late invoice surfaces only if somebody raises it, since billing lives in another system.
- In Nautis: the overdue invoice appears in the 7:00 am briefing with a Send reminder action, and Do it puts a card in the Chief of Staff chat for an owner or admin to review and approve. Runway sits in the same briefing, so the invoice reads as a cash problem. A lagging KPI task is visible on its board, but no ritual brings the team together to solve it.
That difference is the real trade. Ninety makes a team confront a problem together every week and gives everyone one language for it. Nautis puts the whole company in front of one person early, and leaves the meeting habits to you. Founders who already lose track of cash and investors tend to feel the second gap first. Companies of 30 people pulling in different directions tend to feel the first.
Where Ninety is the stronger product
- Method depth. The tools fit together because they follow one system, and a new hire can learn that system from books and coaches outside the software.
- Maturity and adoption. Its pricing page says it is trusted by 18,695+ companies. Nautis launched publicly on Product Hunt in July 2026 and has few independent reviews.
- Scale past 25 people. Nothing on its pricing page caps the number of users, while the largest Nautis startup plan stops at 25 team members.
- A coach-friendly setup. Ninety names EOS coaches and implementers as an audience, so an outside facilitator can run your system inside it.
- Getting started for nothing. You can hold your vision and accountability chart on the $0 plan while you decide.
Where Nautis has the edge, and what it costs you
Nautis fits when the work a founder drops is operational: an investor follow-up, a burn number nobody updated, a contract waiting for signature. Those records live in one place, and the Chief of Staff can see them together. Ninety's Maz can also create and update items after your review, but its scope on the page we read is Rocks, Scorecards, Issues, To-Dos, meetings, the V/TO and the Accountability Chart.
The cost is depth. A dedicated CRM, accounting package or cap table administrator will go further than the matching Nautis module. The default of Ask every time means someone has to review approvals. The briefing also skips sources with no data, so a half-used workspace produces a thin one. If you only want tidier meetings, moving your company's records is a large step for a small problem.
Which of the two fits your company?
- Choose Ninety if you have an EOS Implementer, already speak in Rocks and Issues, or have more than 25 people who need to take part.
- Choose Nautis if you are pre-seed to Series A, raising or about to raise, and the founder is the person joining up finance, sales and investors. See the startup operating system guide for what that looks like.
- Choose neither yet if you are three people who talk all day. Use a shared doc until coordination starts to hurt, then read how to implement a business OS in 30 days.
- Use both only with a clear split. Keep leadership rhythm in Ninety and operational records in Nautis, and decide up front which holds the task list. Two task lists is how things get missed.

FAQ
Which is better in Nautis vs Ninety for a company running EOS?
Ninety. It is built around EOS, with Rocks, Scorecards, L10 meetings, the V/TO and the Accountability Chart. Nautis has no EOS tooling and won't enforce any framework.
How much does Ninety cost?
As of October 2026 its pricing page lists a $0 plan, then Essentials at $12, Accelerate at $14 and Thrive at $16 per user per month. Annual plans get 10% off and are billed upfront. Observers are free, and there is a 30-day trial of Thrive with no card.
Does Ninety have AI?
Yes. Maz is listed on the Thrive plan. It answers questions from your Ninety data and can create or update Rocks, To-Dos, Issues, Headlines and Measurables, and Ninety says you review each suggestion before anything changes.
Can Nautis run L10 meetings?
No. Nautis handles scheduling, calendars and meeting transcripts, and action items can go to a task board. It has no L10 agenda, timers or meeting rating, so an EOS team should use an EOS tool for that.
Is Nautis cheaper than Ninety?
At list price it usually is, because Nautis charges per plan rather than per person: $129 a month for up to 25 members against $300 to $400 on Ninety's Essentials and Thrive. But they do different jobs, Ninety has a $0 plan, and Nautis has no plan above 25 members for startups.
