How Modern Development Practices Are Tackling Real Estate’s Fake Listings Problem
October 1, 2025Building a MarTech Tool: Lessons from Detecting Counterfeit Coins in Digital Marketplaces
October 1, 2025The insurance industry stands at a crossroads. I’ve spent years analyzing how InsureTech innovators can build smarter systems—from claims processing to underwriting. What fascinates me? The eerie similarity between detecting fake “Half Cent” coins and spotting fraudulent insurance claims. Both involve subtle red flags that outdated systems miss. The answer isn’t just better fraud detection. It’s about rebuilding insurance infrastructure with InsureTech tools like insurance claims software, underwriting platforms, and insurance APIs. These tools don’t just stop fraud. They transform how insurers operate.
Why Fraud Detection Is the Canary in the Insurance Coal Mine
Counterfeit coins slipped past top grading services (ANACS, PCGS, ICG) for years. Sound familiar? Legacy insurance systems do the same with fraudulent claims. Outdated underwriting models and manual reviews miss the tiny inconsistencies that scream “fraud.” The FBI estimates non-health insurance fraud costs over $40 billion yearly. That number keeps climbing as cybercrime and synthetic identities get more sophisticated.
Here’s what most miss: fraud isn’t just about bad actors. It’s about bad data. When we can’t verify details at scale, we lose money. Worse? We lose trust. That’s where modern platforms make the difference.
From Coin Diagnostics to Claims Diagnostics
Coin experts spot fakes by examining micro-details: eye shapes, die marks, metal composition, even holder anomalies. Insurance needs its own diagnostic toolkit:
- Micro-anomalies in claims data: Claim filed one day after policy start? Injury description that doesn’t match medical codes? Receipts with duplicate invoice numbers?
- Identity verification: Mismatched biometrics, documents that fail forgery checks, or identities pieced together from stolen data.
- Behavioral patterns: Multiple claims in high-risk areas, or policyholders who consistently claim right before renewals.
Modern insurance claims software uses AI to catch these red flags instantly. Here’s how one team detects outlier claims in production:
from sklearn.ensemble import IsolationForest
import pandas as pd
# Real claims data: claim amount, policy age, claim history
data = pd.DataFrame({
'claim_amount': [500, 2000, 15000, 300, 25000],
'days_since_policy_start': [365, 400, 50, 380, 20],
'claim_history_count': [1, 2, 5, 1, 7]
})
# Find the outliers
iso_forest = IsolationForest(contamination=0.2)
anomalies = iso_forest.fit_predict(data)
print("Anomaly labels:", anomalies) # -1 = red flag
This isn’t future tech. Companies like Lemonade and Next Insurance already use similar models to reject fraudulent claims in seconds.
How Modern Underwriting Platforms Are Replacing “Gut Feel”
Traditional underwriting means actuarial tables and manual reviews. But the “Half Cent” case proved human judgment fails against sophisticated fakes. Smart underwriting platforms work differently by:
- Automating risk scoring: Using real-time data from car telematics, home sensors, even social signals.
- Dynamic pricing: Adjusting premiums based on actual behavior (how you drive, smart home usage).
- Predictive modeling: Flagging high-risk applicants before they ever file a claim.
Case Study: IoT + Underwriting = Fraud Prevention
Take a home insurer using water leak sensors. When a sensor detects a leak:
- Sends an instant alert (stopping water damage fast).
- Logs the event in the underwriting model (lowering premiums for responsible homeowners).
- Flags homeowners who ignore alerts (potential fraud risk).
Companies like Zesty.ai and Ki already use AI to analyze satellite images, weather patterns, and building materials. The result? Loss ratios dropping by 20% or more.
Legacy Systems Are the Real Counterfeit—Replace Them
Just as counterfeiters exploit old minting dies, fraudsters target aging insurance tech. COBOL mainframes, siloed databases, and manual processes create blind spots. The fix? Modernizing legacy systems with cloud-native architectures.
Microservices vs. Monoliths: A Real-World Tradeoff
Instead of one giant claims system, break it into focused services:
claims-validation-service: Uses NLP to scan claim forms for inconsistencies.identity-verification-service: Checks biometrics, device IDs, and credit history.fraud-detection-service: Runs ML models on claim networks.
Here’s how a claims validation API might work (using FastAPI):
from fastapi import FastAPI
from pydantic import BaseModel
app = FastAPI()
class Claim(BaseModel):
policy_id: str
claim_amount: float
description: str
incident_date: str
@app.post("/validate-claim")
async def validate_claim(claim: Claim):
# Check ML models, databases, external services (weather, police)
is_valid = fraud_model.predict([claim.claim_amount, claim.incident_date, ...])
return {"is_valid": bool(is_valid)}
Cloud providers like AWS and Google Cloud offer ready-to-use tools for this shift.
APIs: The “Die Casts” of Modern Insurance
In coin collecting, counterfeiters reuse “transfer dies” to pump out fakes. In insurance, insurance APIs are the new dies—but for good. They let startups:
- Embed insurance in apps (e-commerce, travel sites).
- Connect to verification services (IdentityMind, Onfido).
- Pull real-time data (property records, medical databases).
Actionable API Integrations for InsureTech Founders
1. Fraud Prevention: Check identities with Alloy or Trulioo:
import requests
response = requests.post(
"https://api.alloy.co/v2/evaluate",
json={"application_id": "app_123", "user": {"name": "John Doe"}}
)
print(response.json()["risk_score"])
2. Claims Automation: Extract data from documents using Snorkel:
from snorkel import SnorkelClient
client = SnorkelClient(api_key="YOUR_KEY")
data = client.extract_from_pdf("claim_form.pdf")
print(data["vehicle_license_plate"])
3. Risk Modeling: Get property risk data from Climate Engine:
import requests
response = requests.get(
"https://api.climateengine.com/v1/risk?lat=40.7128&lng=-74.0060"
)
print(response.json()["wildfire_risk"])
Conclusion: Build the Future, Not the Past
The “Half Cent” counterfeit case holds a vital lesson: no system is too established to be compromised. In insurance, the consequences are huge—fraud costs billions, delays payouts, and frustrates customers. But the path forward is clear:
- Modernize legacy systems with cloud-native microservices.
- Deploy AI-powered claims software to catch micro-anomalies.
- Adopt underwriting platforms that use real-time data.
- Integrate insurance APIs for verification, document processing, and risk modeling.
For InsureTech founders, this isn’t just about efficiency. It’s about building systems that resist fraud, adapt to risk, and earn customer trust. The future of insurance won’t run on gut instincts or decades-old code. It will run on clean code, reliable data, and tools that verify authenticity—one API call, one model, and one validated claim at a time.
