Block translates 15% of code on autopilot: Jack Dorsey's AI agents are changing the rules of development
Blockchain company Block, led by Jack Dorsey, has taken a decisive step toward automating development by implementing the AI tool Builderbot. According to my data, this system already generates about 15% of the company's entire software code. This is not just an experiment, but a full-fledged redistribution of engineering resources.
Builderbot is not an ordinary assistant, but an orchestrator of AI agents integrated into the corporate messenger Slack. A developer simply tags the bot and describes the task. The system then independently finds bugs, suggests fixes, or creates new features. The key difference from standard AI assistants is that Builderbot has full access to Block's entire codebase. This means an engineer from the Cash App team can easily make changes to Square services they haven't worked with before. The bot automatically pulls tasks from Jira, creates branches in the repository, writes code, and submits a Pull Request.
The scale is impressive: Builderbot performs over 200,000 operations daily and closes about 1,500 code merge requests weekly. As noted by Block's head of AI capabilities, Brad Axen, what used to take months now takes days. The bot handles routine tasks and environment setup, allowing engineers to focus on solving complex problems.
An important security aspect: the tool works exclusively with source code and system configurations, without having access to customer data or payment information. Architecturally, Builderbot is built on the open-source framework goose, which Block transferred to the Agentic AI Foundation. The company also collaborated with Anthropic to create the Model Context Protocol.
Block is confident that the transition from simple AI-assisted code writing to "native" engineering processes based on neural networks will become the main trend in the IT industry. And it's hard to disagree with that.
Expert opinion: Block's solution is not just automation, but a fundamental shift in the development paradigm. When 15% of code is written without human involvement, it changes project economics and team requirements. In the next two years, we will see such systems become the standard for all major blockchain and fintech companies, and those who fail to adapt risk being left behind.
