Orthogonal raises $4.3M for agent payment rails
Orthogonal raised a $4.3M seed round to build discovery, orchestration and payment infrastructure for autonomous agents.

AI agents will need more than reasoning ability. They will also need ways to discover services, access capabilities and pay for work across the internet.
What happened
Orthogonal raised a $4.3M seed round led by Pantera Capital.
The round included participation from Y Combinator, Pioneer Fund, Decasonic, Blast, Outbound, Surreal and other strategic investors. The company is building a discovery, orchestration and payment layer for the internet, helping autonomous agents access services through one integration.
Why it matters
This is a strong agent-infrastructure signal.
As AI agents become more capable, they will need transaction rails that let them coordinate actions, access tools and pay for services without bespoke integrations each time.
The bigger picture
The AI agent stack is still forming. Beyond models and apps, there may be a new infrastructure layer for agent identity, payments, permissions and service discovery.
