TraitLab Pro vs. Aon: Self-Serve vs. Enterprise Hiring
These two platforms solve fundamentally different problems. Aon Assessment Solutions is an enterprise hiring infrastructure — personality screening embedded in applicant tracking workflows, built for organizations processing thousands of candidates. TraitLab Pro is a self-serve personality assessment for employee development and coaching. If you need to screen job applicants at scale with ATS integration, TraitLab Pro will not help you. If you need research-validated personality insights for team development or coaching without an enterprise sales cycle, Aon is not set up for that. The use cases barely overlap.
Quick Verdict
Choose TraitLab Pro if you need personality assessments for development or coaching and want to start today without enterprise procurement.
Choose Aon Assessment Solutions if you need high-volume pre-employment screening integrated into your existing ATS workflow.
These platforms serve different purposes
Aon is built for pre-employment screening and hiring. TraitLab Pro is built for employee development and coaching. These solve different problems. If you are evaluating job candidates and need personality data flowing into your applicant tracking system, you need a hiring tool like Aon — TraitLab Pro does not offer ATS integration, candidate ranking, or role-fit scoring. If you are developing existing employees or coaching clients, Aon's enterprise-only model and hiring-focused outputs are not what you need.
