COMPARE:
Success.co or Ninety for running EOS
Success.co and Ninety both do running a leadership team on the Entrepreneurial Operating System, and this page puts them on the same seven questions. Mamba Labs builds Apify actors. We have nothing of our own in this category, so this page is two products and no pitch.
Last updated October 6, 2026
The short answer
Ninety is the established platform with the wider toolset and the implementer network. Success.co is the leaner and cheaper one, with AI help built in. A team that only wants the EOS core can save money on Success.co.
Side by side
| Success.co | Ninety | |
|---|---|---|
| What it actually does | Runs the Entrepreneurial Operating System for a leadership team: rocks, scorecards, issues, to dos and the weekly meeting. | Runs the EOS toolkit for leadership teams, with a broader set of tools for companies not strictly on EOS. |
| Coverage and hit rate | Every EOS tool, plus an AI assistant that drafts rocks and summarizes meetings, with integrations into common tools. | Rocks, scorecards, issues, the weekly meeting, an org chart, one on ones and a knowledge portal. |
| What it costs | Per user per month, with a free tier for a small team and a lower price per seat than the incumbent. | Per user per month in tiers, with a free tier and the advanced tools on the paid plans. |
| How it fits a workflow | The weekly meeting agenda runs in the app, and the scorecard pulls numbers from connected tools. | Meetings, scorecards and one on ones in one place, with an implementer network that onboards for you. |
| Where the data comes from | Your own team's goals, numbers and issues. | Your own team's goals, numbers and issues. |
| What it takes to set up | An afternoon if the team already runs EOS on paper or in spreadsheets. | A few days, usually alongside an implementer. |
| Where it stops | It assumes EOS. A team running a different operating rhythm is fitting itself to the software. | The breadth makes it heavier to roll out for a ten person team that only wants the meeting and the scorecard. |
The same seven questions are asked on every compare page here, in this order, so two of these pages can be read against each other.
Who wins what
- Success.co wins on what it costs, what it takes to set up. Software for running a business on EOS: rocks, scorecards, issues and the weekly meeting in one place.
- Ninety wins on coverage and hit rate, how it fits a workflow, where it stops. The best known EOS platform, built around the same tools for leadership teams on any operating rhythm.
- Nobody wins on what it actually does, where the data comes from. Success.co and Ninety give the same answer on those, and we are not going to invent a difference.
Both products
What we would actually do
A leadership team of five to ten people running the weekly meeting, rocks and the scorecard will be well served by Success.co. Its free tier lets you run real meetings before paying. Ninety makes more sense when an implementer is guiding the rollout or when you want one on ones, the org chart and a knowledge portal in the same tool. Both are fine at the core. Trial each through three weekly meetings rather than a demo.
