Internal minions and AI-assisted pull requests

Scale claims

• Verified 91% of Stripe engineers were using AI tools in everyday work.

  stripe.com/sessions/2026/developer-keynote — Stated by Michelle Bu in the Stripe Sessions 2026 developer keynote, published on stripe.com.

• Verified Minions ship over 1,000 pull requests to production every week, with humans reviewing and approving.

  stripe.com/sessions/2026/developer-keynote — Same keynote. "Minion" here is Stripe’s internal agent, not Uber’s platform.

• Verified In March, over 57,000 pull requests were created with the help of AI coding assistance, a 140% increase in three months.

  stripe.com/sessions/2026/developer-keynote — The keynote says "the month of March" in a 2026 talk. It does not publish a fiscal-year qualifier on the page we checked.

• Verified In 2025, agent traffic to Stripe documentation grew 10x, from less than 5% of docs traffic to nearly 40%.

  stripe.com/sessions/2026/developer-keynote — Repeated on the Stripe Projects blog post. Still a first-party Stripe figure, not an independent measurement.
