The Access Group (250 products, 2,000+ engineers) adopted Devin. Cognition reports 5x more merged pull requests than a year earlier; in one test, ten items estimated at two days each came back in twenty minutes.
Reported outcomes
Outcomes are reported exactly as stated by the source; we have not independently audited them.
How it works
- Engineers delegate backlog items to Devin.
- Merged pull requests tracked as output measure.
Risks & compliance
- Agent-written code requires human review and testing
- Vendor-published results; not independently audited
