How Intelligent Document Processing Streamlined FinTech Loan Approvals

From 72-Hour Approval Delays to Under 20 Hours: How AI-Powered Document Automation Helped a FinTech Lender Scale Loan Processing

About the Client

A rapidly growing FinTech lending company in the USA offering digital personal and small business loans. Along with an increase in the applications, there was an increase in documentation associated with it such as bank statements, tax documents, paychecks, identity papers, and other financial papers which needed to be manually verified before underwriting.

Such documentation-heavy process turned out to be a major hurdle in the way of scaling the business.

The Business Challenge

The manual verification of document information was key in the process of verifying the applicant information.A team of 22 analysts review more than 14,000 financial documents each month. In season of high lending, there is a 60% increase in the volume of documents.

The operational impact was substantial:

Average loan processing time exceeded 72 hours for standard applications.
Analysts spent more than 65% of their time extracting and validating information from documents.
Manual review introduced inconsistencies and increased the risk of data-entry errors.
Compliance teams struggled to maintain audit readiness across growing document volumes.
Customer abandonment rates increased as approval timelines lengthened.
Leadership needed to scale operations without significantly increasing headcount.

But That Was Not All

Finding the right professionals for AI and automation was the largest hurdle. With plans for expanding into two more lending markets in just three months, the client required skilled AI engineers, data scientists, and back-end developers who could fit in well within their current lending system environment.

The Solution

Infojini adopted an IDP system that incorporates OCR technology, machine learning algorithms, natural language processing tools, workflow management, and control mechanisms for human review. This system automated the ingestion, classification, extraction, validation, exception management, and reporting aspects of the process.

Automatic document classification: The ML models classified documents related to finance, identity, and income, and hence no need for manual categorization.
Data extraction using AI: The data extraction and standardization were performed automatically through OCR and NLP on structured and unstructured documents.
Automatic data validation: The rules and external data sources were used for data validation.
Automation of underwriting: The validated data were incorporated into the underwriting process, whereas exceptions were assigned to underwriters.
Regulatory compliance and audit trail: The automated audit trail makes the auditing process easier.
Real-time monitoring dashboard: This allows the monitoring of processing time and workload of underwriters.
