I'm Humayun Khan — product designer and builder.

For over a decade, I've been designing digital products across healthcare, education, and enterprise—helping teams at startups and Fortune 500 companies ship meaningful software. My focus is on AI-powered platforms, design systems, and rapid prototyping.

Currently, I lead product design for healthcare startups through my consulting practice, working on everything from telehealth platforms to clinical research tools. Recent clients include Practice with Joy, NIA Health, ClassDojo ($1.25B valuation), and Ruth Health (YC W21).

I've also built my own products. QueryCat was a marketplace connecting authors with literary agents—bootstrapped to $300 MRR and 1,000+ users. More recently, I've been using Claude and Cursor to build Mindscape, a journaling app based on Internal Family Systems therapy.

Before consulting, I was Product Manager at Xello and Design Lead at Roadmunk (acquired by Tempo) and Tiny Hearts (acquired by Shopify). I started my career in growth marketing at Shopify.

Currently available for consulting engagements, founding designer roles, or full-time positions. Based in Montreal, open to remote.
