Pick Demand Curve if

What Demand Curve's Frontier gives you

The library page says "Everything we've ever published" and counts 387 pieces: playbooks, articles, teardowns and newsletters (issues #341 to #352 are on the first page). By topic it shows Growth Strategy 133, AI & Growth 22, Paid Media 21, Copywriting & Messaging 20, Landing Pages & CRO 14 and SEO & Content 12. Demand Curve's home page now leads with "the growth agency for startups", so the library sits beside services and a $995 Growth Program.

What Growth.Design gives you

52 UX case studies (the count in its page title), each a comic of 2 to 9 minutes, filed under Psychology, Ethics, Onboarding, Retention, Revenue and Referral, plus a page of 106 cognitive biases and principles. Its Product Psychology Masterclass is 5 modules over 5 weeks, self-paced, lifetime access, a final exam and a certificate, at "Price ~1500 USD"; its page says registrations ended September 25, 2026 and reopen January 25, 2027.

Where Demand Curve wins

  • Volume: 387 pieces against 52 case studies.
  • A course you can buy today, at $995, where Growth.Design's is closed.

Where Growth.Design wins

  • Psychology. It names 106 principles and ties each case study to one.
  • Short, visual lessons: 2 to 9 minutes against playbooks of 11 to 57.
  • A certificate after a final exam. Demand Curve shows none.
