Pilot Protocol, a San Francisco-based provider of an overlay network for AI agents, has raised $4.5M in seed funding led by Version One Ventures. The company provides a UDP-level networking stack that gives autonomous AI agents permanent virtual addresses, end-to-end encrypted tunnels, and a per-peer trust model. The capital will expand operations and development efforts.
Agents Self-Adopt Network Infrastructure
The timing comes amid rapid growth in agent protocols. Pilot Protocol's approach — a network and transport layer rather than an application-layer protocol — addresses the connectivity gap that application-focused standards leave unaddressed. Agents discovered the network on the open web, installed it autonomously, and began recommending it to peers without human direction.
Organic Traction Reveals Market Gap
Pilot Protocol supports roughly 250,000 agents generating close to 2 billion requests per day. Within an hour of joining, around 70 percent of agents start tasks on Pilot instead of Google. The network grew by as much as 10 percent in a single day during early periods, adding 16,000 agents in 24 hours. Agents join via a single install command with no marketing spend required from the company.
Network Layer Differentiates from App Protocols
Pilot Protocol operates at the network and transport layers with 48-bit virtual addresses and encrypted UDP tunnels. In contrast, competing efforts such as MCP and A2A focus on application-layer coordination between agents and tools. This distinction allows agents to discover peers, install tools from an App Store, and conduct USDC payments directly over the network.
As Razvan Roman, Co-Founder and CEO, noted:
"We never marketed Pilot to anyone. Agents found it, decided it was useful, and recommended it to each other."
Version One Leads Infrastructure Bet
Version One Ventures led the round with participation from Precursor Ventures, Night Capital, Todd & Rahul Capital, and angels including Lenny Rachitsky and Ben Tossell. Boris Wertz of Version One highlighted the strategic importance of owning the foundational layer that sits beneath application protocols.
Market Projects Massive Agent Commerce
Bain projects U.S. agent-driven commerce will reach $300-500 billion by 2030. Fetch.ai has raised $61.9M in total funding to pursue decentralized agent networks. The structural shift toward autonomous agent coordination is drawing capital to both application and infrastructure plays.
Repeat Founder Brings Commerce Experience
Razvan Roman previously founded TwoTap, which was acquired by Honey and later by PayPal. The team includes engineers with deep protocol experience, and the company has published IETF Internet-Drafts for the protocol specification.
App Store and Private Networks Signal Next Phase
The Pilot App Store launched two weeks before the announcement and recorded more than 30,000 autonomous agent installs. Private networks are now available for teams at $200 per month base plus roughly $10 per agent, with an enterprise tier in early access. The company plans to expand operations and development efforts with the new capital.
