OrthogonalOrthogonal

Pros

  • Solves real friction — agents need API access without manual key management
  • Strong founder backgrounds in payments (Coinbase, Vercel) and API infrastructure (Google)
  • 30+ API partners already onboarded showing solid early supply-side traction
  • MCP-native design aligns with the emerging agent protocol standard
  • Pay-per-call model with no commitments is agent-friendly

Cons

  • Marketplace cold-start problem needs both API providers and agent developers
  • Commoditizable if major cloud providers build native agent API marketplaces
  • No public revenue or usage metrics disclosed
  • Thin margin business if acting purely as a payment pass-through

  • Strong CTO with deep reverse engineering expertise

Cons
