Corefy is a payment orchestration and white-label infrastructure platform designed for payment institutions, PSPs, fintech companies, large merchants, and digital platforms managing complex payment operations. The platform consolidates fragmented payment stacks into a single configurable system where businesses can manage payments and payouts, routing and cascading logic, analytics, tokenisation, anti-fraud controls, and operational workflows. Instead of building and maintaining multiple direct integrations, companies connect once to Corefy and gain access to 600+ pre-built connectors with global PSPs, acquirers, and alternative payment providers. At the core of Corefy is a powerful routing and cascading engine powered by 100+ attributes, including custom metadata. This allows businesses to define granular traffic distribution rules based on geography, BIN, currency, transaction parameters, risk signals, historical performance, or other custom conditions. Routing strategies can be adjusted without rebuilding infrastructure, enabling optimisation of approval rates, load balancing across providers, and more controlled risk management. Corefy also provides white-label capabilities for organisations launching or scaling their own payment products. The platform supports merchant account hierarchies, role-based access control, reporting, and operational tools needed to run payment businesses efficiently. For organisations that want to expand connectivity without complex migrations, Corefy offers Payment bridge — a lightweight extension layer that enables rapid rollout of new payment integrations on top of existing systems. The platform has processed over 1 billion transactions and powers dozens of active payment providers and platforms worldwide.
