Effectiv is an AI-powered fraud and risk decisioning platform for fintechs and banks to orchestrate real-time fraud detection across the customer lifecycle.
About
Effectiv is an AI-powered fraud and risk decisioning platform that enables fintech companies and financial institutions to build, deploy, and manage fraud prevention workflows across the full customer lifecycle — from account opening and identity verification through ongoing transaction monitoring and step-up authentication. The platform's orchestration engine allows risk teams to connect multiple fraud signals — device intelligence, identity verification results, behavioral biometrics, transaction patterns, and third-party data enrichment — into a unified decisioning pipeline that evaluates each event in real time and executes the appropriate response without requiring bespoke engineering for each integration. This orchestration approach allows risk teams to add, remove, and reconfigure fraud signal sources as the threat landscape evolves without rebuilding the entire detection infrastructure.
