In this episode, Lucas and Luna examine a shift in how bootstrapped software companies charge for their products: usage-based pricing. Rather than flat monthly fees or per-seat licensing, a growing number of profitable SaaS founders are tying revenue directly to customer consumption — charging per API call, per gigabyte stored, or per transaction processed. They explore why this model aligns incentives, reduces churn, and unlocks expansion revenue, using examples from Stripe, Twilio, and a lesser-known bootstrapped analytics tool called Plausible. Lucas shares data showing that usage-based pricing companies grow 20-30% faster than subscription-only peers, and Luna pushes back on the risk of unpredictable bills for customers. Together they unpack the three rules bootstrapped founders should follow before switching to consumption-based pricing: start with a flat baseline, cap the downside for early customers, and instrument everything from day one. The conversation also touches on why the model works particularly well for B2B API-first products. No ads, just a straight-up discussion for founders building sustainable software businesses.
