Case studies

What GrantsProof catches.

Synthetic case studies authored from public-data fraud patterns and the JIL Sovereign team's prior work on healthcare and federal payment integrity. Each study walks step-by-step through what the Verdict Engine would surface, how the CREB attestations stack up in court, and what a recovery engagement looks like end-to-end.

Synthetic note. Names, organization details, and timelines are fictional and do not reference any real foundation, grantee, or individual. The fraud patterns, however, are drawn from substantiated sector cases and from the JIL team's 12+ years building payment integrity infrastructure.

Personnel-payroll inflation, equivalency-determination forgery, milestone-evidence fabrication, and cross-foundation orchestrated giving studies are in drafting. Each represents a distinct failure mode that the 148-check Verdict Engine catches at a different category.
