How To Launch A Product or Feature To Maximize Growth

Brian Balfour Free Intermediate

Balfour argues that a big, splashy launch to everyone actually hurts you: it buries the signal you need under noise from people the product was never built for. He lays out a narrower, staged approach (using Superhuman as the case study) that's built specifically to produce a clean read on whether it worked.

  • A broad launch attracts the wrong users and drowns your real signal in noise
  • Launch to a narrow, well-matched audience first and look for concrete success signals before expanding
  • Word of mouth and long-term engagement, not launch-day spikes, are what a launch should be judged on
