Due Diligence Intelligence

Decision-support for venture firms: upload a startup cap table, screen every owner (including UBOs behind shell layers) against OFAC/EU sanctions lists, and get a plain-English risk report with an ownership graph and AI-generated analyst notes.

The brief

Venture firms doing sanctions/compliance screening on cap tables have to manually trace ownership through shell companies and holding structures, then cross-reference each name against sanctions lists by hand. It's slow, easy to miss a layered UBO, and produces no structured audit trail.

The outcome

01Full ownership-chain traversal (BFS) surfaces beneficial owners hidden behind shell-company layers, not just direct owners
02Three-tier confidence classification (clear <0.80 / review 0.80–0.95 / flagged ≥0.95) keeps false positives out of the officer's queue
03Production split across Vercel (frontend) and AWS EC2 (backend + sanctions matching engine) for independent scaling

The build

The pipeline parses a cap table CSV, builds a directed ownership graph, traverses it to surface ultimate beneficial owners, screens every node against OFAC SDN and EU Consolidated lists, and classifies each as clear, review, or flagged.

Claude writes a plain-English narrative (who, why, confidence, next step) for anything that isn't clean. The tool never renders a verdict; it narrows the review set for a human compliance officer.
