SettleGrid vs Stripe Metronome
Stripe acquired Metronome for $1 billion, signaling how critical usage-based billing has become. Metronome is enterprise-grade usage-based billing designed for complex pricing at scale. SettleGrid is purpose-built for the AI economy: a 2-line SDK with progressive pricing, AI-native discovery and metering, and support for 15 payment protocols. Both platforms handle usage-based billing, but they serve very different worlds.
