We are a London-based startup transforming how financial professionals access and use data. We are building a system of intelligence empowered by AI-driven automation and analytics: a category-defining product that supercharges users to extract knowledge and put it to work.
Backed by top international venture funds and a stellar group of angel investors, we are a team of technologists and founders with experience in building AI products (@Advent International) and scaling unicorns (@Scalapay).
We are currently looking for rockstars to join our core team. Together, we will build Desia from the ground up and establish it as the global leader in financial intelligence.
This is a London-based hybrid position, requiring at least two days per week in our office.
