The company

We build the transparency layer for cleared derivatives.

Cumulus9 is reshaping risk management for exchange-traded derivatives. We use cloud technology to unlock new dimensions in margin forecasting and risk analytics, so financial market participants can anticipate how requirements move under stress — before the stress arrives.

Services

We take the burden of managing data and complex margin methodologies away from derivatives professionals, so they can operate more effectively.

Mission

Increase the transparency of derivatives margin models and improve the ability to assess market risk — leaving market participants better prepared for stress events, and reducing systemic risk across the industry.

Vision

To be best in class globally for risk analytics on exchange-traded derivatives, creating software that simplifies and improves how market risk is assessed.
