Project Overview

BankrollX, a Canadian neobank specializing in small business lending, faced a critical challenge in their onboarding process. Small business owners were abandoning loan applications due to lengthy qualification processes and unclear repayment terms. The bank needed a solution that could provide instant loan eligibility and transparent repayment calculations.

Led by former TD Bank executives Rachel Kim and David Thompson, BankrollX wanted to revolutionize SMB lending by providing the same instant gratification that consumers expect from modern financial services. They needed a sophisticated yet user-friendly loan calculator that could integrate seamlessly with their existing KYC and onboarding systems.

📊 Risk Assessment Integration

The calculator integrates with multiple credit scoring APIs to provide instant eligibility decisions. We implemented a weighted scoring system that considers business age, revenue, credit history, and industry risk factors to determine loan terms and interest rates.

🔗 Seamless Bank Integration

Using RESTful APIs and webhook architecture, we integrated the calculator directly into BankrollX's existing banking platform. Loan applications flow seamlessly from calculator to KYC verification to final approval without manual intervention.

🛡️ Security & Compliance

All financial data is encrypted in transit and at rest using AES-256 encryption. We implemented comprehensive audit logging, data retention policies, and privacy controls to meet Canadian banking regulations and PIPEDA requirements.
