Fiserv Finxact vs Tuum

Fiserv Finxact is a cloud core-banking engine and system of record for transactions across asset classes, currencies, and time zones. Its event-driven microservice architecture processes in-balance transactions in real time, avoiding end-of-day and batch reconciliation. The platform can recreate as-of views of transactions, events, or occurrences without cutoffs or offline operations. RESTful APIs provide thousands of banking functions and full CRUDL access to customer and transaction data. Product owners and business analysts can define event rules with a TypeScript domain-specific language. Production deployments use Kubernetes on Amazon Web Services, Microsoft Azure, and Google Cloud Platform clusters. Core payments include single-bank processing, basic ACH, checks, and debit cards; Payment Rails adds ACH, RTP, and wire capabilities. Finxact integrates with third-party fraud and AML tools, while RabbitMQ queues let external endpoints subscribe to process or database conditions. Developer resources include a sandbox, on-demand instances, documentation, API references, a learning academy, and configuration wizards. It serves financial institutions, fintechs, commerce brands embedding finance, and community institutions. Pricing is consumption-based and available on request.

Tuum is a modular core banking platform for banks and financial institutions, with capabilities for accounts, payments, lending, cards and Islamic banking. Customers can select modules, and an API-first microservices architecture is intended to support incremental modernization alongside legacy systems. Deployment options include public cloud, private cloud, on-premises and hybrid environments. Tuum says open APIs and pre-built integrations connect third-party systems and providers. Listed payment integrations include Centrolink, Currencycloud, LHV and Banking Circle, with AML connectivity from ComplyAdvantage and Hawk; card connections include Nets and Paymentology, plus Mastercard tokenization through MDES. The platform supports multi-currency accounts and virtual IBANs, card issuing and processing, and payment operations including SEPA, SWIFT, FX and direct debits. Tuum states support for more than 2,500 transactions per second and 99.99% uptime. Its Islamic Banking module is described as AAOIFI-compliant. Tuum says average core banking implementation takes less than seven months. Founded in 2019 and headquartered in Tallinn, Estonia, the company offers pricing on request and directs prospective customers to book a demo. It is a software vendor, not a provider of an EMI or banking license.
