  • Not enterprise-wide deployment

2. Security Doubt

  • Data governance = biggest roadblock

3. ROI Unclear

  • 40%+ companies struggle to measure AI impacts
  • McKinsey: 39% report measurable EBIT impact

4. Price Pushback

  • $30/user faces resistance
  • New tier: $21 Copilot Business
  • Oct: bundled Sales/Service/Finance
