About Kal Grinberg
Head of Design at Factory
I’m the Head of Design at Factory, where I joined as the founding designer three years ago. Since then, I’ve helped scale the company to a $5B valuation while serving as the sole product designer through much of that growth.
My work has spanned product strategy, UX, design systems, brand, and building the design function itself—often working directly with founders and engineering teams to turn early ideas into products used at scale.
I’m especially interested in mentoring product designers navigating high-growth startups, founding design roles, career progression, design leadership, and the evolving relationship between design, engineering, and AI.
I’m happy to talk through portfolios, career decisions, startup design challenges, or how to increase your impact as a designer beyond the pixels.
