The Challenge

Early 2025, a fintech startup applied for a £60K loan from CTM but was rejected due to limited financial history & first-time founder & misunderstood revenue forecast metrics. 3 months later, the startup secured $700K VC funding. CTM got criticised in startup circle, causing reputation damage despite wasted resources for the previous credit analysis. 3 problems were raised:

  • Systemic blind spots: 60% of startup applicants got rejected by outdated scoring methods.
  • Competitive pressure: Their startup-lending unit underperformed for 3 consecutive quarters, losing share to AI-enabled fintechs.
  • Rising risk: Ironically, several approved SMEs defaulted within 6 months based on tax data the system was built to trust.

 

The Solution

Technical Approach: CTM partnered with a regional AI consultancy to develop StartLens, an intelligent credit risk system that understands modern startups. 

Key Components:  

  • Alternative data fusion: Leverages non-traditional data sources—founder backgrounds, business plans, user growth metrics, and live platform data (e.g., Stripe, Xero).
  • Reinforcement learning: Learns from credit analysts’ overrides to refine decision logic in real time.
  • Smart escalation: Flags high-uncertainty cases for human review, with AI-generated summaries.
  • Regulatory guardrails: Integrated fairness and compliance checks to prevent bias and ensure transparency.
  • Embedded APIs: Seamless integrations with business platforms for real-time performance data.
