Ninety alternative
Unbreakable OS vs Ninety
Ninety is software for running EOS®: quarterly Rocks, a weekly Level 10 Meeting™ and a scorecard. Unbreakable OS runs on a different rhythm: a monthly cycle where every idea is pitched, decided once a month, and reported in writing every week.

| Â | Unbreakable OS | Ninety |
|---|---|---|
| Planning cycle | Monthly priorities. Twelve chances a year to decide and correct course. | Quarterly Rocks. |
| Weekly rhythm | A written update from each priority owner: on course or deviating, what got done, challenges and next steps. No weekly status meeting. | A weekly 90-minute Level 10 Meetingâ„¢. |
| How ideas get chosen | Anyone pitches in writing against a big goal. An AI review checks every pitch first, and the leader who owns that goal decides at the monthly meeting. | Issues are raised and solved in the weekly meeting. |
| Scorekeeping | Every priority ends executed or failed, and rolls into an execution rate for each person, each area and the whole company. | Rocks marked on or off track, plus a weekly scorecard. |
| Getting started | Set it up yourself in the app, with how-to videos for every screen. No implementer needed. | Built for EOS. Many EOS companies also hire an EOS Implementer. |
| AI | Every pitch gets an AI review before the meeting: it checks the idea against its big goal, says whether it’s ready to decide, and asks what would make it ready. Leaders still make every call. | Maz, an AI assistant, on the Thrive plan. |
| Mobile apps | iPhone and Android apps. | iOS and Android. |
| Free trial | 45 days free. $0 charged during the trial. | 30 days on Thrive, no card. |
| Pricing | $195 a month for up to 10 people, then $20 a seat to 25 and $12 a seat after. Never more than $995 a month. Yearly billing gets 2 months free. | Per user, per month: Free, Essentials $12, Accelerate $14, Thrive $16. Annual plans use the same rates, billed upfront. |

Why teams pick Unbreakable OS
Twelve decisions a year, not four
Priorities last a month. A bad call costs you a month instead of a quarter, and work doesn’t pile up in the last weeks of the quarter.
No weekly status meeting
Owners write an update every week: on course or deviating, what got done, challenges and next steps. Leaders read it on their own time instead of sitting in a meeting.
Weak ideas never reach the room
Every idea is pitched in writing against a big goal and screened by an AI review before the monthly decision meeting.
The whole company takes part
Anyone can pitch, every priority has one owner, and everyone can see whether the month is on course.

Common questions
- Is Unbreakable OS an EOS tool like Ninety?
- No. Unbreakable OS isn’t built on EOS. It runs a monthly cycle instead of quarterly Rocks, and written weekly updates instead of a weekly meeting. It was built by a CEO who ran his companies on EOS before building his own rhythm.
- How do ideas get decided without a weekly issues list?
- Anyone pitches an idea in writing against a big goal. An AI review checks it first, and the leader who owns that goal decides at the monthly decision meeting, in about eleven minutes per idea.
- Can we switch from Ninety partway through the year?
- Yes. Keep your annual goals as your big goals, turn this quarter’s Rocks into this month’s priorities, and run your first decision meeting at the end of the month.
