Peter Piatetsky

Peter Piatetsky is the co-founder and CEO of Castellum.AI, a New York compliance-technology company that automates AML/KYC screening for banks, credit unions, fintechs and crypto firms. A former US Treasury sanctions officer who once fined banks and froze illicit assets, he started Castellum after a month of staring at 38,000 compliance alerts that surfaced exactly one real threat. The company builds its own financial-crime data pipeline, refreshes it every five minutes, and routinely corrects errors in government sanctions lists. In July 2025 Castellum raised an oversubscribed $8.5M Series A led by credit-union and bank-backed funds.
