Scaling Your Agent Workforce: Lessons from Inside Cognition

Most companies have turned coding agents on. Few can say what those agents do or what they return. At Cognition, Devin wrote 92% of merged PRs in September, and 9 out of 10 Devin sessions start without a human. Theodor Marcu shows how we got there: cloud agents working in parallel, automations that run every night, and how engineering and research use Devin to autonomously drive feature development. He then turns that into a playbook for your teams: govern what agents can reach, route work across models to cut cost, and follow every session to a merged PR so ROI is measured instead of guessed.
