Block has implemented Builderbot, an AI tool that automates 15% of its code development, significantly speeding up software tasks.
Blockchain firm Block, co-founded by Jack Dorsey, has adopted the AI system Builderbot to enhance its software development process, with the tool now responsible for generating approximately 15% of the company’s code.
Operated within Slack, Builderbot functions as a coordinated AI agent, enabling developers to tag the bot and specify their tasks. The AI autonomously detects errors, proposes solutions, and can create new features, streamlining the workflow.
One of its standout features is full access to Block's codebase, empowering engineers from the Cash App team to modify Square services without prior experience. The bot automates task retrieval from Jira, manages repository branches, composes code, and submits Pull Requests.
Builderbot reportedly executes over 200,000 operations daily and successfully closes roughly 1,500 code merge requests each week. Brad Axon, head of AI capabilities at Block, noted that tasks which previously spanned months can now be completed in days, as the bot handles mundane tasks, enabling engineers to tackle more complex challenges.
Block assures that Builderbot operates strictly with source code and system configurations, maintaining the confidentiality of customer data and payment info.
Developed on the goose framework, an open-source initiative supported by Block, Builderbot is part of a partnership with Anthropic to create the Model Context Protocol (MCP). The company anticipates a significant shift towards AI-driven engineering processes within the tech industry.
