The AI Record
As of early April, 100% of Block employees are using AI tools to do their work. One of these tools is Builderbot, which serves as both a multiplier for employees and an end to end automation layer, embedded across our engineering workflows, automating support, reviewing code changes, and initiating production-ready builds.

How this was checked

Checked against the source by a first reader, then confirmed independently by a second reader who fetched the source without seeing the first reader's notes (Independent review agent (Claude Sonnet), blind second pass from passage text and citation only, no repository access, 2026-11-04).

sec.gov returned its 'Undeclared Automated Tool' block page to curl and to headless Chrome, so I matched against the Wayback raw capture of the same exhibit, taken the day of filing. The wording matches exactly. The EDGAR full-text search also confirmed this is the Block 8-K EX-99.1 filed 2026-05-07.

In early 2024, we began developing goose, which was the first agentic harness to enable foundation models to execute work across an enterprise. That work is now changing how Block runs. Velocity continues to increase. As of mid-April, production code changes per engineer are up over 2.5x compared to January.
