[Case Study] Marketing AI OS "ENSOR" adopted by Sports Field — "Governance-first AI to boost team productivity"
Overview
REHATCH Inc. announces the adoption of ENSOR by Sports Field, a sports talent recruitment company. Sports Field aims to build a zero-copyright-risk AI creative workflow while improving team productivity at scale.
Background
Growing demand for ad creatives was straining internal capacity. At the same time, management had concerns about copyright and portrait rights risks of generative AI. ENSOR was introduced in February 2026 under the condition: "We'll adopt it if there's a governance framework in place."
Challenges
- Creative production demand was overwhelming internal bandwidth
- Generic AI tools lacked adequate risk management for copyright and portrait rights
- Teams had no time to learn prompt engineering before needing results
Expected Outcomes
Sports Field targets 20 hours/person/month in time savings while building a workflow with zero copyright risk. A 30% improvement in CPA is also in scope, alongside faster creative PDCA cycles.
