## Reported outcomes
- engineers using the agent: approximately 14,000 [1]
- technology vendor spending: declined 30% year over year [1]
- product launch speed: 30% – 40% improvement [1]

## How it works
1. Engineers delegate development tasks to the Devin agent.
2. More work done internally instead of by external vendors.

## Risks & compliance
- Code quality and security review of agent output
- Attribution: vendor-spend and launch-speed changes have multiple causes

## Notes
- Outcomes are company-reported in earnings commentary and relayed by an independent publication.
