Block, a company founded by Jack Dorsey, unveiled a new suite of AI tools. Developers claim these solutions are already capable of handling around 15% of all production code changes within Block.
The new tool is called Builderbot. According to the company, it can process more than 200,000 operations per day and merge around 1,500 pull requests per week.
“The best way to think about Builderbot is as the missing layer between AI coding tools and how engineering actually works at scale,” said Brad Axen, head of AI capabilities at Block. The company added that tasks that used to take months can now be completed in days.
Builderbot is an orchestration layer that coordinates the work of multiple AI agents across the company’s entire codebase.
Unlike typical programming assistants, which are usually limited to a single repository, Builderbot understands Block’s entire codebase: every service, API and internal convention. This allows any engineer to make changes across any part of the company’s systems.
“An engineer working on Cash App can use it to make a change in a Square service they’ve never touched, because the system already understands how that service works,” the company said.
This means development can be scaled significantly: AI takes on repetitive tasks, while engineers focus on the decisions that shape the product.
“It means an idea can go from backlog to live in front of millions of customers in days instead of months,” Axen added.
Block said it is sharing details about Builderbot because it sees the shift from AI-assisted coding to AI-native engineering as one of the most important discussions in the technology industry today.
“The problems we’re solving aren’t unique to Block: orchestrating AI agents across a massive codebase, maintaining quality at speed, and keeping humans focused on judgment and taste rather than scaffolding,” the company said.
Block is Jack Dorsey’s financial technology company, which develops an ecosystem of digital payments, banking services and business solutions. Its key products include Square for payment acceptance and commerce management, Cash App for transfers, investments and personal finance, and Afterpay for buy now, pay later services. The company operates at the intersection of fintech, commerce and consumer finance, helping businesses accept payments, manage sales and interact with customers.
A separate area of Block’s business is linked to Bitcoin and digital asset infrastructure. The company invests in the development of cryptocurrency services, hardware solutions and open technologies that can expand access to financial tools. By combining payment products, consumer applications and technology initiatives, Block positions itself not merely as a payments company, but as a platform for a new financial ecosystem.
As a reminder, earlier this year Block decided to cut 40% of its staff. At the time, Dorsey attributed the move to the rapid acceleration of AI adoption within the company.
