Orthogonal

Orthogonal is a B2B infrastructure startup operating from an unspecified location that develops agentic payment systems for application programming interfaces. The company provides a specialized platform that allows autonomous artificial intelligence agents to instantly discover, access, and execute payments for hundreds of different APIs. This underlying infrastructure functions entirely without requiring traditional recurring subscription models or lengthy enterprise sales processes. By utilizing a streamlined pay-per-use framework, the software enables third-party API providers to list their services once and automatically collect revenue each time an external agent initiates a call. Operating with a lean team of two employees, the early-stage enterprise is currently backed by the prominent startup accelerator Y Combinator as part of its Winter 2026 investment cohort. Orthogonal was recently established by an undisclosed team of founders ahead of its upcoming accelerator participation.
