The Challenge

Starting position

  • 14% win rate in AI-generated head-to-head comparisons against CodeSignal, Codility, and HackerEarth
  • Industry-leading question library and AI-powered plagiarism detection were invisible to AI recommendation engines
  • Engineering leaders asking AI for assessment tool recommendations were consistently pointed to competitors
  • Crowded 7-competitor market with no differentiated AI search positioning despite enterprise-grade infrastructure

The Approach

What Rex did

  • Deployed 13 topic agents across the full spectrum of technical hiring queries — startup assessments, enterprise pair programming, AI screening, and pricing
  • Built 85 content pieces matching the exact evaluation frameworks AI models use when comparing developer assessment platforms
  • Targeted high-intent segments: startup-specific needs, AI-powered proctoring, and direct pricing comparisons
  • Structured content to highlight unique differentiators — plagiarism detection, question library depth, enterprise security
