Orthogonal Raises $4.3M Seed for AI Agent Infrastructure

Orthogonal has secured $4.3 million in seed funding. The company plans to use this capital to develop infrastructure for AI agents, focusing on discovery, orchestration, and payments. Pantera Capital led the funding round, with contributions from Y Combinator, Pioneer Fund, and other strategic investors. Orthogonal aims to provide AI agents with a unified platform to find services, access capabilities, manage workflows, and complete payments across the internet. The company notes that current AI agents often fail or require human help when encountering tasks needing new capabilities. Orthogonal's solution allows agents to describe their needs, then composes results by calling the right services in the correct order. The platform currently supports over 35 APIs and is already in use with go-to-market teams and AI-native startups. The company plans to expand from dozens to thousands of integrated services and scale its developer and agent ecosystem over the next 12 months. This development is important because it could enable AI agents to perform complex tasks independently, transforming how they interact with online services.
