What happens when CI actually works
These teams eliminated flaky test noise, cut merge times by 75%, and reclaimed thousands of engineering hours - without building it themselves.
P90 time to merge down 30%. 50% of merge queue failures eliminated.
150,000+ tests across a JS/TS monorepo, merging at scale without flake-driven retries.
330 hours saved in 35 days -9.4 hours of engineering productivity back per day.
Flaky tests surfaced, quarantined, or fixed -not ignored.
CI reliability from 70% to 90%+. 10,000+ PR runs unblocked.
75% merge time reduction on day one -from 6+ hours to 90 minutes.
160 PRs/week, 20-minute average queue time.
30-40 PRs merged per day. Engineers submit and walk away.
“"Agent-based PRs is more of a thing now. And also non-engineers opening PRs is a thing now, so CI reliability has become extremely important, and our CI has scaled to meet that demand."”
