Stripe Puts AI Coding “Minions” to Work, Merging Thousands of Pull Requests Weekly

Stripe, the global payments infrastructure leader, is pioneering a new era of developer productivity by deploying  AI-powered coding agents — internally dubbed “minions” — to automate large swaths of software development work. According to Stripe’s own internal disclosures, these AI agents are capable of autonomously generating and merging over 1,000 pull requests per week, producing fully tested code changes that are then reviewed by human engineers.

Unlike typical assisted coding tools that suggest snippets, Stripe’s minions are unattended, end-to-end agents that take tasks from start to finish: a developer posts a request in Slack, the minion interprets the task, writes the code, runs it through continuous integration (CI) checks, and generates a pull request — all without intermediate human interaction. Stripe views this capability as a way to parallelise work, reduce developer context switching, and free up engineering talent for higher-value challenges.

The initiative reflects broader trends in software engineering where generative AI moves beyond simple code completion toward fully automated task execution. For Stripe, which processes more than $1.4 trillion annually, this model promises not only speed but also a scale of engineering throughput that would be impossible by manual coding alone.

Key Highlights

• AI coding agents deployed: Stripe’s internal system of unattended AI agents — dubbed “minions” — autonomously complete coding tasks and generate pull requests.
• High throughput: Stripe reports over 1,000 minion-produced pull requests merged each week.
• Workflow integration: Developers trigger tasks via Slack, and the AI reads context, produces code, runs CI checks, and creates pull requests ready for human review.
• Human oversight maintained: All AI-produced code is still subject to human review and testing before final merge — blending automation with quality control.
• Productivity strategy: Stripe sees unattended agents as a way to reduce dependence on intense developer attention and to “parallelise” tasks.

What “Minions” Are and How They Work

Stripe’s “minions” aren’t whimsical pets — they are purpose-built AI agents designed to interpret developer instructions and execute full coding tasks end to end. Unlike traditional copilot-style tools that suggest snippets within an IDE, these agents autonomously:

1. Consume task context from developer messages posted in Slack threads, including links to relevant docs or repos.
2. Generate complete code changes, designed to address the task’s requirements without human prompts during execution.
3. Run the code through continuous integration (CI) tests to ensure it meets quality and stability standards.
4. Create a pull request that developers can review and merge with confidence.

Stripe engineers can launch multiple minions in parallel, allowing them to coordinate the completion of many tasks at once — effectively enabling a form of asynchronous software production that is rare in traditional engineering environments.

Why Stripe Is Betting on Autonomous Coding

Stripe’s adoption of autonomous coding agents is part of a broader industry transition where companies experiment with full-cycle AI workflows rather than simple assisted development. The key motivations include:

Speed and Scale

By reducing the time engineers spend on repetitive or straightforward coding tasks, AI agents can dramatically increase throughput — generating orders of magnitude more pull requests than traditional manual development would allow.

Efficiency in Developer Attention

Stripe has noted that developer attention is one of its most constrained resources. Unattended AI agents help parallelise work, enabling teams to tackle more features and bug fixes simultaneously.

Human-in-the-Loop Quality Assurance

While minions handle code generation and CI testing, humans still review all outputs. This hybrid model ensures quality control while leveraging AI for bulk production — a practical balance of speed and reliability.

Broader AI Integration at Stripe

Stripe’s use of autonomous agents is part of a larger wave of AI adoption across the company and the fintech industry:

• Stripe is also expanding capabilities that let AI agents pay automatically using new protocols like x402 on Base with USDC — allowing autonomous systems to transact without human intervention.
• Stripe has built integrations and partnerships to deepen the role of AI in payments infrastructure and fraud detection.

Together, these innovations reflect Stripe’s strategy to not just support AI-driven development internally but also to enable AI-powered commerce and agent-level interactions on its platform.

Challenges and Considerations

While the “minion” model offers clear productivity gains, it also raises key questions for engineering teams and the broader tech ecosystem:

• Code reliability: Ensuring that AI-generated code integrates safely with complex, production-grade systems requires strong CI, testing, and human review processes.
• Tooling transparency: Teams must maintain clear visibility into how autonomous agents operate to avoid unintended security or logic issues.
• Ethical and governance concerns: As AI manages increasingly complex tasks, policies on accountability, traceability and compliance become critical.

Stripe’s model — pairing high-throughput automation with human oversight — offers a pragmatic blueprint for other technology organisations exploring similar paths.
