Habit tracker to ~$10K/mo on ads growth curve, devs.dev daily issue #4

Issue #4 · Tuesday, October 27, 2026

☕ THE COLD OPEN

  • 💰 A “boring” habit tracker: ~$10K/mo on ads alone (founder-reported)
  • 🍰 Kaught: one redesign took onboarding→paywall from 40% → 80%
  • ⚡ Anthropic files its S-1 — 80% of revenue is builders on Claude
  • 🧠 AI got up to 80% cheaper — redo your napkin math

Money first. Numbers you can steal.
