Introducing Chunk™: The agent that validates code at AI speed
Chief Technology Officer
The software development landscape has fundamentally shifted. Teams are shipping more value faster than ever, leveraging AI to generate code at unprecedented speed. But with this velocity comes equally dramatic complexity — small teams now face challenges that once belonged only to large organizations, while large organizations grapple with codebases that strain human comprehension.
This complexity isn’t a bug — it’s a productivity opportunity to embrace. Every line of complex AI-generated code represents capability you didn’t have before. The challenge isn’t eliminating complexity, but building validation that keeps pace with it. Get it wrong, and complexity drags down productivity. Get it right, and you unlock AI’s full potential.
Teams want to ship as fast as they’re generating code — the same goal as always, just now under exponential AI-driven pressure. This creates two equally problematic paths: ship what you haven’t fully validated, risking production issues and mounting tech debt, or sacrifice all your AI productivity gains by creating manual validation bottlenecks that feel like trying to find a needle in an ever-growing haystack.
Traditional CI/CD approaches are hitting their breaking point. It was challenging enough to validate human-generated code at human speed. With AI-generated code’s volume, velocity, and complexity, the old paradigms simply can’t keep up. What’s needed isn’t just faster CI/CD — it’s fundamentally smarter validation that can move at AI speed while maintaining enterprise-grade confidence.
Enter autonomous validation
The solution isn’t just faster CI/CD — it’s fundamentally smarter validation. Teams need autonomous systems that can match both the pace and complexity of AI development with minimal human intervention. This means validation that moves as fast as AI-generated code, works around the clock, and eliminates CI/CD toil rather than creating more of it.
This isn’t about replacing developers — it’s about unleashing them to focus on what matters most while AI handles the validation toil that traditionally consumed so much time and mental bandwidth.
That’s why we built Chunk — a specialized autonomous agent designed to clean up the parts of your software delivery process that everyone knows are important but no one has time to maintain. Unlike static automation, Chunk learns from your codebase’s unique patterns, development practices, and team preferences, getting smarter and more precise with every run.
Chunk in action: Intelligent CI/CD at AI speed
Chunk represents a fundamental shift from reactive to proactive CI/CD. While you sleep, Chunk optimizes — identifying and fixing flaky tests, repairing red builds, and finding efficiencies. You wake up to healthier code and streamlined pipelines, giving you and your team more time to stay in flow and tackle complex challenges.
24/7 autonomous fixes
Chunk works while you sleep, fixing failed builds, optimizing configs, and eliminating flaky tests. You can trigger specific tasks on-demand, but Chunk’s real power is proactive—maintaining your CI/CD workflows on your schedule, preventing disruptions before they happen, and freeing your developers to focus on what only humans can do.
“Waking up to a PR sure beats spending the day investigating.” (Director of Engineering at a health and social services platform)
Adaptive intelligence that learns your patterns
Unlike static one-size-fits all automation, Chunk continuously improves based on your development practices, guardrails, and production outcomes. It understands and implements your team’s optimal build, test, and deploy processes, turning each team into your best team.
“The fixes do appear reasonable, for some fixes it even used our custom commands like to wait on certain network requests.” (Lead Developer at an interactive learning company)
Lightning-fast orchestration
Reduce your time-to-green to mere minutes with capabilities like pipeline optimization, selective testing, and strategic ordering.
Bring your own key (BYOK) security model
Just plug in your existing LLM keys — no new contracts, no security reviews, no markup on tokens. Your data stays exactly where it is today, governed by whatever deal you already have with Anthropic or OpenAI. We’re adding more LLM providers soon, but the principle stays the same: you keep control, we do the work.
Real results from real teams
We started with flaky tests — those frustrating and time-sucking non-deterministic failures that kill developer productivity (roughly 8 minutes lost per job). It’s the perfect proving ground for autonomous fixes because if Chunk can handle the unpredictable stuff, it can handle anything. During our private beta, Chunk opened pull requests for 90% of the flaky tests it analyzed — a massive improvement over manual debugging.
Our beta customers say it best:
“The nicest thing is the model has picked up on some of our utilities for making sure network operations are complete and uses those to improve test reliability, so the fixes do tend to adhere to our best practices for reliable tests. Overall, I think we’re batting ~60% for fixes, so plenty of room for improvement, but a clear improvement over fully manual flaky test investigation.” (Director of Engineering at a health and social services platform)
