Block Inc. is offering Builderlab, the agent tools it built to run itself, to other businesses, SiliconANGLE reported from the Builderlab Launch Event 2026 in San Francisco. Builderlab builds on Buzz, Block's open-source workspace where AI agents have names, avatars and their own identities, can be tagged like colleagues and leave an audit trail. Buzz first launched in July, and plug-ins were added later.
Companies can self-host the code, use a free tier or add funds for remote agents, models and extra storage, according to Buzz product lead Lucas Isaza. Brad Axen, head of AI capabilities at Block, said Builderlab works with agents from any AI lab, that remote agents run in central cloud environments for overnight work, and that some teams have shipped software releases 50% to 75% faster. He expects agents to need much less human steering within the next year.
Chief Information Security Officer James Nettesheim said every agent gets a full identity owned by a human, runs in hardened cloud virtual machines and records its actions in a cryptographically signed ledger. Block is also building information flow control to keep sensitive data from leaking. SiliconANGLE noted Block said little about commercialization or Cash App, which brings in 60% of its revenue. TheCUBE, SiliconANGLE's video arm, was a paid media partner for the event.
