② VR Exposure Therapy

• Clinical results:
  ✓ 40% better PTSD treatment response
  ✓ 50% shorter social anxiety treatment cycles
• Innovation: Meta group therapy rooms (12,000+ monthly active groups)

③ Digital Phenotyping

• Harvard study: Smartphone usage predicts bipolar episodes (92% accuracy)
• Applications:
  • Mindstrong: Keystroke dynamics for cognitive monitoring
