About Thought Machine

Our mission is ambitious: to permanently eliminate outdated legacy systems from the global banking sector. To make this a reality, we’ve engineered a cloud-native foundation for modern core banking and payments. We tackle complex challenges, which is why we prioritize bringing together exceptional talent to build world-class technology.

In just a few years, we’ve expanded to a global team of over 500 professionals across London, New York, Singapore, and Sydney. Backed by $500m in funding and a $2.7bn valuation, our investors include the likes of JPMorgan Chase, Temasek, and Standard Chartered. Beyond the tech, we’ve fostered an award-winning culture—consistently recognized by Sifted and the Financial Times for our high Glassdoor ratings, generous equity packages, and workplace excellence.
