Most assessment platforms stop at the report. BolderBrain carries the same data into development, then measures whether the development worked. Here is an honest comparison, including where Mettl is the better buy.
Three patterns come up again and again in conversations with L&D and HR leaders.
You get a score, a profile and a PDF. Turning that into individual development actions, and later proving the actions changed anything, is manual work in a spreadsheet.
Proctoring, large test catalogues and high-volume delivery are what an assessment platform is optimised for. If your question is about growing existing employees, much of that capability is unused.
Measuring whether a training programme worked usually means another tool, or another vendor, and the two datasets never meet.
Same eleven categories we use on the full comparison, scored the same way.
| Capability | BolderBrain | Mettl |
|---|---|---|
| 360° Multi-Rater Feedback Self, peer, and manager assessments with configurable templates | ||
| Cognitive ability testing Numerical, verbal, spatial, and logical reasoning | ||
| EQ (Goleman-based) Testing Emotional intelligence across 5 domains | ||
| Psychometric (Big Five/OCEAN) Full personality profiling with validity checks | ||
| TNA / Training Needs Analysis Gap-driven training identification and planning | ||
| Pre/Post Training Impact Measure training ROI with paired assessments | ||
| AI Coaching & Insights Personalized AI-generated development narratives | ||
| Automated Action Engine Post-assessment dev plan with streak tracking | ||
| 9-Box Talent Grid (Auto-Suggest) Evidence-based talent mapping from assessment data | ||
| Skills Inventory Heatmap Real-time competency gap visualization | ||
| Single Integrated Data Model One platform connecting all assessment data |
Based on publicly documented product capabilities at the time of writing. A blank cell means the capability is not part of that product's documented surface, not that the vendor cannot deliver it as a service.
A comparison that only goes one way is not worth reading. These are the cases where we would tell you to stay.
If you are screening thousands of candidates and need remote proctoring, identity checks and a broad catalogue of ready-made tests, Mettl is built for exactly that.
Their library spans technical, aptitude and behavioural testing, so a single vendor can cover most hiring requirements without procurement work.
As part of Mercer, the commercial and compliance paperwork that large organisations require is already in place.
Every completed 360, EQ or cognitive assessment generates a development plan with weekly actions and progress tracking. The employee sees what to do on Monday, not just what their profile says.
Pair an assessment before and after a training programme and the platform reports what moved. That is the one capability no competitor in our comparison covers.
360, cognitive, EQ and personality results sit in one place, so a competency gap found in one instrument is visible in the development plan and in the training plan.
Bring the assessment you already run and we will map it to the same eleven categories, then show what the development side looks like with the data joined up.
