Resistant AI is a fraud detection company focused on financial services, offering two core products: Resistant Documents and Resistant Transactions. Resistant Documents is an AI-powered document fraud detection solution that analyzes submitted documents for signs of forgery, tampering, or AI-generation. It is designed to process documents from any country in under 20 seconds, and is used in workflows such as merchant onboarding (KYB), loan underwriting, and insurance claims processing. The platform aims to reduce manual review workloads for fraud and compliance analysts. Resistant Transactions is an AI layer designed to augment existing rule-based transaction monitoring systems. It provides over 80 pre-built machine learning models developed by AI and financial crime experts to detect fraud and money laundering behaviors, including AML (anti-money laundering), APP (authorized push payment) fraud, and BNPL (buy now, pay later) fraud. The solution is positioned as an add-on rather than a replacement for existing tech stacks, delivering detection in under 100 milliseconds. The company serves financial institutions including banks, payment providers, lenders, and insurers. Clients include Payoneer, Raiffeisen Bank, Credit Agricole, Moneta Bank, Lemonade, and Siemens, among others. The platform combines document analysis, transaction monitoring, behavioral signals, and identity data to provide layered fraud and financial crime prevention. Resistant AI is headquartered in Prague, Czech Republic.
