I’m Cath Macaulay, a principal-level product designer with 15+ years of experience.
I lead complex projects and build design systems. I also help organisations make confident decisions in regulated and high-risk environments.
Former first design hire. Experienced in working with compliance, risk, and senior stakeholders in FCA-regulated environments.
I use behavioural UX, accessibility, and systems thinking to help teams simplify high‑stakes decisions and bring clarity to ambiguity in fintech and beyond.
