The system is a SaaS platform allowing the client to evaluate solvency and reliability of the potential borrowers using statistical methods of analysis of the historical and nontraditional data sources such as social network profiles and others. It allows the client to upload his normalized and anonymized database of previous loans data, build mathematical models and calculate the credit score of the future potential borrowers entering their data through the system’s web interface.
Looking for a partner to build a banking app, a digital wallet, or a trading platform in Chicago?
You’re in the right market. Chicago blends deep finance roots with practical engineering. Buyers here care about security, traceability, and uptime. They also expect clean payment gateway integration and open finance APIs that survive real audits.
First, the CFPB finalized the Personal Financial Data Right rule, often called open banking. Banks and fintechs must provide secure consumer-permissioned data access and follow defined third-party obligations. That makes API quality, consent flows, and audit trails non-negotiable.
Second, ACH keeps growing. Same Day ACH crossed the one-billion-payments mark in 2024. Capacity planning and exception handling now sit in the core backlog, not at the edges.
