A SaaS business from day one, THETA is a London-based FinTech innovator on a mission to redefine trading in capital markets. It provides global enterprise software through its cloud platform, offering users a web-native digital user experience.

Key to THETA’s mission is addressing nearly two decades of under investment from current technology providers that fail to adapt to the changing market structure demands and the evolving trading landscape. THETA provides technology innovation for capital markets whilst interoperating with the broader ecosystem.

Lean delivery is a cornerstone of THETA’s services. Its user subscription-based model offers you speed to market and simplifies future deployments in the event of new regulations or other market changes. The model also lends itself to flexible pricing in line with changing needs, while ensuring ongoing reinvestment in the underlying technology.

The founders of THETA have capital markets domain expertise with deep contextual understanding of the design and delivery of buy-side and sell-side strategic trading technologies, market structure and regulatory transformative solutions.
