Finding Product-Market Fit: A Startup’s Toughest Challenge

Bastian & Markus

Every startup works towards product-market fit, but how do you really know when you’ve reached it? Without it, scaling too early can be a costly mistake - yet waiting too long can mean missing the market. In this episode, we break down the process from early validation to measurable traction, sharing lessons from our own journey at Flinn.ai.

What we cover:

  • The different stages of product-market fit and how to measure progress.
  • Common myths vs. reality - why “you’ll just feel it” isn’t enough.
  • The metrics that matter: NPS, retention, churn, and referral rates.
  • How we approached product-market fit at Flinn.ai, from LOIs to our first paying customers.
  • The nuances of achieving PMF in B2B SaaS vs. B2C.
