30 to 70 PRs a Day: How We Managed to Not Wreck Our Systems

Summary

In this two-part blog series, I give a detailed report-out on how our Honeycomb engineering team 2.5x-ed our throughput using AI without breaking everything or lowering our standards for quality. Part 1 explains how we did it and shows data about how that ramp-up happened. Part 2 shares what we learned.TL;DRPeak-weekday merges roughly doubled (~30 to ~74) as AI-attributed lines went from near-zero to a floor of 82.6% of new code by June 2026. Incidents grew too, tracking that change volume about as linearly as you'd expect; the goal now is keeping each failure cheap to contain, not holding the count flat.The gains came in three phases: slow experimentation (2025), a tooling-driven adoption bump (October 2025), then a step-change in delegation intensity after Opus 4.6 shipped in February 2026—same engineers, same tools, but they stopped supervising every step.Our core thesis: AI amplifies your existing practices. It makes a dysfunctional org more dysfunctional and a high-autonomy, high-ownership org faster. The practices—continuous delivery, fast and AI-legible CI, closed-loop observability, CLAUDE.md, feature flags—are the actual story, not the multiplier.Why did I put that big number in the title? It’s the number that gets you to click. But we’re going to dig into all of the caveats and details beyond just 2.5x-ing our throughput, including whether we let quality slip. This blog and its companion post are our report-out on what we did to achieve that result, how we kept the systems underneath that throughput from falling over, and what we learned in the process.Setting out to double productivity in a yearIn mid-August 2025, our founders sent a letter to the whole company, not just engineering: each of us should aim to double our productivity over the next year. It was addressed to individuals; the framing underneath it was a team sport, not an individual race, and nobody was supposed to read it as a contest with their teammates. The letter named Darragh Curran’s In...
