How Stripe deploys 1,300 AI-written PRs per week

At Stripe, we're landing about thirteen hundred PRs that have no human assistance besides review per week. A lot of where our work begins is it could be in a Google Doc as we're planning a new feature, or maybe a Jira ticket comes in, or we're talking about something in Slack. I can click an emoji, and then the Minion will sort of attempt to one-shot resolving that prompt using all the tools that are available at Stripe.

When you're in larger organizations, there's so much friction that can come between a good idea and getting it into the world.

Not only can I have one of these, but I could have many, many of these running in parallel in isolated environments, making isolated changes all at the same time.

How are you getting all this code review done?

Whether the text has been written by Steve or the text has been written by Steve's robot, you still want that CI environment that's providing confidence that the code that's being changed is safe, and that as it rolls out, we're having blue/green deployments, so you can roll back, too. All that is super critical, independent of the nature of the authoring of it.

No matter how juiced these laptops are, you get three or four worktrees in, and, like, it starts to sound like an airplane taking off. It's no good. And so I do think on this multi-threading agentic engineering work, cloud environments and virtual environments are so important to unlock velocity. [upbeat music] Welcome back to How I AI. I'm Claire Vo, product leader and AI obsessive, here on a mission to help you build better with these new tools. Today we have Steve Kaliski, a software engineer at Stripe, and he's gonna show us how the Stripe team deploys a bunch of Minions to do their engineering work. We'll also watch an agent spend a little bit over five dollars to plan a birthday party, all in Claude Code. Let's get to it. This episode is brought to you by Optimizely.

Steve, I'm so excited to have you on How I AI because I saw the Stripe Minions on the timeline, and one, exceptional branding, don't sue us, and two, I just love the idea that you and your colleagues in the team at Stripe have created not just one agent, but minions all across the company that can help with development work. And I'm so excited for you to show us how that helps you in your day-to-day here. So welcome to How I AI.
