Deqian Jia, Co-founder
Deqian studied Philosophy and Physics at Oxford, then spent a brief stint in M&A at Barclays early in his career — enough to see firsthand how broken data rooms were. Clunky interfaces, opaque pricing, weeks of setup for a single deal. He went on to build products across AI, operating systems, file management, and document security, including a note-taking app that 15% of Oxford signed up for.
Peony is where those two threads meet: a builder who obsesses over file systems, security, and product craft, applied to an industry he first encountered inside an investment bank. Deqian leads engineering and product at Peony.
