The Crego AI Lending Platform Transformation A Fintech Success Story Powered by AWS AI

The Moment of Truth

In early 2024, Crego — India’s fastest-growing AI-native lending platform — faced a critical challenge weeks before its launch. 

We expect thousands of real-time AI credit decisions per minute and hundreds of concurrent loan applications,” said the CTO.

Our legacy on-premise MySQL and rule-based workflow will collapse under this scale. Any outage risks losing customers, trust, and regulatory compliance.

The Harsh Reality We Discovered

  • Legacy monolithic lending systems with manual credit evaluation. •  
  • Slow rule-based processes: ~2–3 days per loan application. 
  • No AI-driven decisioning or workflow automation. •  
  • Security gaps: no encryption at rest for sensitive customer data. •  
  • Zero ability to scale to multi-tenant, high-throughput workloads. 
  • Limited observability, monitoring, and auditability. 

Immediate and long-term risks threatened both market launch and regulatory complianc

The New Foundation: AWS AI-Powered Lending Platform

Crego partnered with AWS to build a cloud-native, scalable, secure AI platform, capable of delivering real-time lending decisions across multiple financial institutions. 

Core AI & Compute Layer 

  • Generative AI: Amazon Bedrock (Claude-2) for semantic analysis of loan applications and historical customer data. 
  • Containerized Orchestration: Amazon ECS + Fargate for AI workflow automation and real-time decisioning. 
  • Persistent Storage: Amazon RDS MySQL for structured transactional data; Amazon S3 for unstructured loan documents and historical datasets. 
  • Real-Time Scaling: Auto-scaling ECS clusters handled thousands of concurrent AI scoring requests with sub-second latency. 

Performance Achieved: 

  • Credit evaluation time: days → minutes (~85% faster) •  
  • Operational cost reduction: ~40% savings via AI automation 
  • Real-time loan approvals: thousands of decisions per minute 1 Agentic AI Practice: Smarter Decisioning 

Customer Requirements Analysis: 

  • Automate credit scoring and risk evaluation across multiple financial institutions. •  
  • Integrate historical and real-time transactional data with low latency. 
  • Ensure auditability, security, and regulatory compliance. •  

Agentic AI Workflow: 

  • Data ingestion triggers ECS workflows from S3. 
  • Pre-processing validates and normalizes loan data. 
  • Bedrock models perform semantic analysis, scoring, and risk evaluation. •  
  • ECS orchestrates rule-based overrides, stores outputs in RDS, and logs all activity. •  
  • Continuous feedback loop improves AI model accuracy over time. 

Security & Compliance (RBI-Style Governance) 

  • Authentication & Authorization: AWS IAM with fine-grained RBAC. 
  • Data Encryption: KMS-encrypted RDS/S3 storage, TLS 1.2+ in transit. 
  • Monitoring & Audit: CloudWatch + CloudTrail track all agent activity, AI inference, and workflow execution. 
  • Operational Security: Zero-trust controls with automated policy enforcement and compliance logging. 

Responsible AI Implementation 

  • Bias and fairness checks against historical loan datasets. •  
  • Explainable AI outputs with rationale for regulatory auditability. •  
  • Safety thresholds and rule-based overrides prevent unsafe lending decisions. 
  • Continuous production monitoring and iterative improvements based on feedback. 

Compute Infrastructure Highlights 

  • Amazon ECS + Fargate: Containerized AI workflows with serverless scaling. 
  • Streaming AI Inference: Bedrock models accessed via ECS tasks, ensuring low latency and high throughput. 
  • Cost Optimization: Right-sized containers with auto-scaling reduce idle compute costs. 
  • Data Integration: ECS workflows interact with RDS and S3 for a secure, fully managed compute 
  • pipeline. 

Launch Day: AI Stack at Scale

  • Concurrent users: 4,300+ active loan applicants. •  
  • AI decisions processed: 180,000+ per hour. 
  • Latency: p95 query latency < 20 ms; end-to-end offer generation < 90 ms. 2
  • Uptime: 99.999%, including Multi-AZ failover. 
  • Customer impact: Zero disruption, real-time approvals, instant satisfaction. 

Beyond Survival: Tangible Wins

  • 50% reduction in total cost of operations vs legacy systems.
  • Continuous compliance reporting reduced from days → minutes using automated AI workflows. 
  • Multi-tenant AI workloads scaled seamlessly across multiple financial institutions. •  
  • Faster feature rollouts enabled Crego to outpace competitors and deliver new lending products in weeks.
