Founding Designer
Who We Are
Over the next few years, every financial institution will have teams of AI analysts working alongside their sharpest minds. At Endex, we're on a mission to bridge the present to the inevitable by building the most sophisticated digital coworker native in Excel. We're a team working on the frontier of agentic development and applied finance, in close collaboration with leading research labs and backed by OpenAI ($14M Raise in Aug. 2025).
With significant demand after our launch, financial firms across the country recognize agentic AI in financial modeling is the future.
