15Five
vs SuccessionStack
15Five is a continuous performance platform that includes a 9-box Talent Matrix. SuccessionStack is a dedicated succession tool. This page is about where the Talent Matrix is enough and where it runs out.

Where 15Five is the better fit
- Performance management is the actual problem, and succession is a report you look at once a year.
- You have a handful of critical roles, and the Talent Matrix on your existing review cycle gives you enough visibility.
- Weekly check-ins, goals, and engagement matter more to your team than an auditable succession record.
- Adding a second vendor is harder for you than living with succession tracked outside the tool.
Where SuccessionStack is the better fit
- A board or regulator will ask who covers a critical seat, and the answer has to be evidence rather than a name.
- You need readiness windows and bench coverage across 15 to 30 roles, not a placement grid from one review cycle.
- You want every score change to carry a recorded reason, so the reasoning survives staff turnover.
- You want to model a departure and see which other plans go thin before it happens.
Questions buyers actually ask
15Five documents a 9-box Talent Matrix inside its review reporting, which is the assessment step succession planning starts from, but its public documentation does not describe succession plans, readiness windows, or bench coverage as features. In practice teams tend to use the Talent Matrix to identify people and then track the actual succession plan somewhere else. Whether that is enough depends on how many critical roles you are planning for.
It is a 9-box grid built from review results: you pick two dimensions from your review questions, such as a performance rating and a manager assessment answer, and participants are plotted across the resulting nine cells. It supports filtering by people group and demographic attributes, saved filter presets, and export to CSV or XLSX. It is a reporting view on a review cycle rather than a standing record of a succession plan.
No. 15Five is a continuous performance platform: weekly check-ins, goals, engagement, and reviews. SuccessionStack does succession planning only and has none of that. If you run performance on 15Five, you keep running performance on 15Five; the question is only where the succession layer lives.
When your actual problem is performance management rather than succession, when the Talent Matrix on your existing review cycle is enough visibility for the number of critical roles you have, or when adding a second vendor is harder than living with a reporting view. A team with five critical roles and a working review cycle probably does not need a dedicated succession tool yet.
When succession has to survive an audit or a board question months later: scores with a recorded reason for every change, readiness windows someone would actually act on, and what-if modeling that shows which other plans go thin when one person leaves. A 9-box built from a review cycle answers where people sit today; it does not answer who covers this seat and on what evidence.
