Castellumai

New York-based financial-crime compliance platform focused on sanctions, PEP, adverse-media, KYC/KYB, transaction screening, and AI-assisted alert adjudication for banks, fintechs, credit unions, crypto, and other regulated institutions. The strongest evidence is not generic ‘compliance AI’ but operational screening work: Castellum.AI claims 94% fewer false positives, 83% less time on L1 alert reviews, watchlist updates every five minutes, and AI agents that resolve L1/L2 alerts with documented, audit-ready reasoning. Legal relevance is real but narrow. This is not a day-to-day law-firm workflow product; it is for in-house AML, BSA, fraud, risk, and compliance teams, with legal or regulatory counsel involved in escalation, policy, and exam readiness. Public proof is better than many batch vendors. The site contains dedicated pages for fintech compliance, APIs, pricing, SOC 2, and GTI integration, and there is some third-party or practitioner signal: PitchBook/Tracxn funding data, a Lead Bank case study, a small but real Reddit mention in r/AMLCompliance, and explicit competitive comparison pages against LexisNexis. The caveat is source mix: many outcome claims still come from Castellum-controlled pages, and public pricing remains mostly demo-led despite a pricing landing page.
