Spanlink Raises $48M Series A for Web Retrieval Infrastructure Built for Autonomous Agent Fleets

  • Agent Infra
  • Retrieval
  • Web Agents

Agent-native web retrieval that plans multi-hop fetches, caches structured evidence, and returns citation-ready spans so production agents stop improvising on the open internet.

“Agents do not need another search box. They need a retrieval control plane with budgets, proofs, and a kill switch.”

— Founder

“Web access is the new data center for autonomy—Spanlink is productizing the layer everyone is bolting on by hand.”
