Tom Han
Coming from a data science background, I spent years in the quantitative world before stepping into the marketing space — turning "calculation" into craft. Before "individual SaaS entrepreneur" became a trendy title, I was already a Pre-SaaS-era super-indie: solid with quantitative strategies, fluent in data products, capable across full-stack SaaS, and handy with mobile apps. These days I'm focused on AI-powered innovation solutions — no hype, just results — building practical AI-powered banking solutions that actually ship.
My core work sits at the intersection of fintech and retail banking digital transformation. An old-school FDE, I've gone from hand-crafting models with SAS in the early days to orchestrating AI agents at scale. I've always believed in "data-driven decisions," the perfect match between "business" and "algorithms," and helping banking clients navigate the world of big data, models, and AI without getting lost or stumbling.
