Stanford Quants Launch Castle to Hedge Macro Risks for Small Businesses
menhguin · x · 2026-08-14
Startup Castle aims to address hidden macro risk exposures on corporate balance sheets.
- Core Insight: Many companies unintentionally carry macro event risks (e.g., an airline is an embedded oil trade, a data center is a bet on permits clearing). These intangible risks lack historical data and remain unprotected.
- Solution: Founded by former quantitative traders, Castle leverages market models to cover risks that insurers won't, providing liquidity for these exposures so businesses can focus on operations.
- Origin: Four Stanford grads left their plush quant jobs and spent weeks with goat herders in the Central Valley to understand small business risks, leading to Castle's creation.
