Who for
Financial institutions
Business model
API subscriptions
Effort
A few months

Financial institutions often struggle to get realistic test data that doesn't expose sensitive information. A service could use advanced AI models to generate synthetic market data that preserves statistical properties of real markets without containing actual trades. Hedge funds and banks would pay for API access. Start with basic stock price generation, then expand to more complex instruments. The main risk is ensuring the synthetic data truly behaves like real markets.
