Orthogonal raises $4.3M seed to build a discovery, orchestration and payments layer for AI agents

What's the deal? Orthogonal, a San Francisco-based startup, has raised $4.3 million in seed funding to develop a discovery, orchestration, and payments layer for AI agents.

The round was led by Pantera Capital. Y Combinator, Pioneer Fund, Decasonic, Blast, Outbound, and Surreal also took part.

Led by Bera Sogut, Orthogonal is building a protocol that connects AI agents, handles machine-to-machine payments, and routes data across platforms.

Why now? AI agents are moving from chatbots to tools that act on their own — booking, buying, and transacting. That shift creates demand for infrastructure that lets them find each other and pay each other.

Orthogonal plans to use the money to grow its engineering team, scale its multi-chain transaction routing, and push adoption among developers.

What could go wrong? The startup is betting on a Web3 financial layer to power agent payments, a model still unproven at scale.

It also faces a crowded race, with rivals and crypto giants chasing the same agentic-payments market.

The signal: The cap table reads like a Web3 conviction bet, pairing crypto-native funds such as Pantera Capital, Decasonic, and Blast with a Y Combinator pedigree. For a startup Dealroom already classes as breakout stage, that mix signals confidence that the rails for an agent economy will be built on-chain rather than through traditional payment infrastructure.
