# Sardine's $25M Extension: When Your Customer Becomes Your Lead Investor

> National Bank of Canada led Sardine's $25M Series C extension after live deployment — total funding hits $170M as agentic fraud AI scales.

The best VC diligence is **production traffic**. National Bank of Canada didn't just write a check to Sardine — they **deployed first, then led a $25M extension**.

### What happened
- **$25M Series C extension**, NAventures (NBC's CVC) leading  
- **Multi-year contract** across retail, commercial, and wealth  
- **Total funding: $170M**  

### Why "agentic AI" in fraud isn't hype here
Sardine's **financial crime agents** automate investigation workflows — the bank explicitly cited agentic AI in risk and compliance as category-defining.

### Pattern to steal
1. Land pilot with measurable KPIs (fraud caught, false positives down)  
2. Convert pilot → enterprise contract  
3. **CVC doubles down** with extension round  

### Practical takeaway
**Founders selling to banks:** Your champion needs **ops metrics**, not security theater.  
**Investors:** Customer-led rounds are the strongest signal in fintech — if the bank writes twice, believe them.
