Ninety (ninety.io): EOS software pros, cons and an alternative
Ninety puts EOS into software. Clearahead starts from a different model, and has AI run it
The short answer
Ninety is software built for companies that run on EOS: Rocks, Scorecards, Issues, To-Dos, Level 10 meetings, the Accountability Chart and the V/TO, all in one place. Clearahead isn’t built around EOS. It holds one goal, the constraints holding it back and the moves that clear them, with AI keeping it current and no prescribed meetings. If you run EOS and want it digitised, Ninety is the natural choice. If you want to move away from the meetings and the manual upkeep, look at Clearahead.

What is Ninety?
Ninety, at ninety.io, is software for companies that run on EOS, the Entrepreneurial Operating System. It describes itself as an AI-powered business operating system for companies running on EOS, and it brings the EOS toolkit into one place: Rocks, the weekly Scorecard, the Issues List, To-Dos, the Level 10 Meeting, the Accountability Chart and the Vision/Traction Organizer, plus feedback, assessments, a knowledge portal and a mobile app.
For a team that has been running EOS on whiteboards and spreadsheets, Ninety replaces the paper. The weekly meeting runs inside it, with the agenda, the timers, the numbers and the issues together, and Rocks and To-Dos carry from one week to the next. Ninety reports more than 18,000 companies running on it.
Where Ninety came from
Ninety exists because EOS spread. Gino Wickman's book Traction came out in 2007, EOS Worldwide was founded in 2008, and as thousands of companies took up the system, they needed software to run it. A small market of EOS tools grew up, and Ninety became one of the best known. We've covered EOS itself, its history, strengths and weaknesses, in EOS vs Clearahead, so this page focuses on the software.
Ninety pros and cons
What Ninety does well, and where it struggles.
Where Ninety shines
- It’s made for EOS, so the tools match what an implementer teaches, name for name.
- It brings the whole EOS toolkit together: Rocks, Scorecard, Issues, To-Dos, meetings, Accountability Chart and V/TO.
- It runs the Level 10 Meeting for you, with the agenda, timers and issues in one place.
- It replaces the spreadsheets and paper that many EOS teams start with.
- Ninety reports a large user base, so plenty of teams and implementers already know it.
Where Ninety struggles
- It assumes EOS. If you’re not running EOS, much of it won’t fit how you work.
- It makes the meetings easier but doesn’t remove them: the weekly 90 minutes is still the engine.
- The Scorecard, Rocks and Issues still need people to update them.
- The structure is the EOS structure: 90-day Rocks rather than a continuous loop.
- Like EOS itself, it centres on the leadership team.

How Ninety and Clearahead differ in practice
Comparing Ninety with Clearahead is really comparing two models. Ninety is a very good way to run EOS. Clearahead runs a different model, the operating model for the AI era, built on the Theory of Constraints.
A better meeting, or fewer meetings
Ninety makes the Level 10 Meeting smoother: everything you need is on screen and the agenda keeps time. But the meeting is still where the picture gets refreshed. Clearahead moves that work out of the meeting. Owners tell AJ in a sentence when a move starts, gets stuck or finishes, and AJ writes This week from AJ with up to three things that need a decision. People still meet, but only when a decision needs the team together.
Rocks, or constraints
In EOS, the leadership team picks a set of Rocks every 90 days. In Clearahead, there's one goal per workspace, and the team names the constraints that are really holding it back, in the order it chooses. Every move sits under the constraint it's meant to clear, and when a constraint clears, the team finds the next one, without waiting for the next quarter.
The leadership team, or everyone
EOS software is mostly used by the leadership team and the teams that report to it. Clearahead is built for the whole company to work in one model, and for advisers, investors and board members to follow as Viewers at no extra cost.
What Clearahead doesn't do
Clearahead doesn't have the V/TO, the Accountability Chart, a weekly Scorecard, a meeting runner or people assessments. If those tools are central to how you lead, Ninety gives you all of them, and Clearahead would leave gaps.
Should you choose Ninety or Clearahead?
Choose Ninety if
- You run EOS, with or without an implementer, and want one place for all its tools.
- Your leadership team values the Level 10 Meeting and wants it to run smoothly.
- You want the Accountability Chart, Scorecard and V/TO alongside your priorities.
- Your implementer recommends it and your team already knows it.
Choose Clearahead if
- You want to keep the focus EOS gave you without the weekly meeting and the manual updates.
- You don’t run EOS, and don’t want to adopt a whole system to get a tool.
- You want the whole company, not just the leadership team, working in the same picture.
- You want AI to do the chasing, the updating and the weekly summary.
Our honest read
If you've committed to EOS and it's working, pick EOS software; you'll get more value from tools that match what your implementer teaches than from bending something else to fit. Ninety is a strong option there.
The teams we see considering Clearahead are the ones asking a different question: not "how do we run EOS better?" but "do we still need to run it this way?" If your Level 10 has started to feel like the job, if the Scorecard is filled in on Monday morning just before the meeting, or if the rest of the company never sees the Rocks, it may be worth trying a model where AI carries the information and people spend their time on decisions.
Questions about Ninety
Is Clearahead a Ninety alternative?
For teams that want to move beyond EOS, yes. Clearahead covers the jobs Rocks, Issues and the weekly meeting do, without the meeting or the manual updates. It doesn’t replicate EOS tools like the V/TO or the Accountability Chart.
Can I run EOS in Clearahead?
Not as EOS. Clearahead has its own model: one goal, constraints and moves. Some teams use their one-year plan as the goal and treat Rocks as moves, but if you want EOS exactly as an implementer teaches it, dedicated EOS software fits better.
Does Clearahead have a scorecard?
No. Clearahead tracks evidence on the goal, each constraint and each move, rather than a weekly table of numbers. If a weekly scorecard is central to how you run, keep it alongside.
How do Ninety and Clearahead use AI?
Ninety describes itself as AI-powered; see its site for the specific features. In Clearahead, AI is how the product works: you set the goal by talking to AJ, update it by telling AJ, and AJ writes the weekly brief and flags what needs a decision.
