Brennan Zambo

Solo founder and maintainer of Zambo, the verifiable work layer for AI. I build open infrastructure that lets anyone check what an AI agent actually did: the AER-1 open standard for verifiable execution receipts, its conformance corpus and reference verifiers, and a live MCP server with 153 tools at zambo.dev/mcp. As of November 9, 2026 the public receipt stream holds 123,262 receipts, the open packages have 216,307 downloads across PyPI and npm, and five independent implementations pass the AER-1 conformance corpus, with a sixth independent party validating it.
