I’m Nathaniel Sidwell, also known as 'Than.'
I’ve worked across startups, agencies, and enterprise teams—guiding design strategy, building systems, and leading cross-functional collaboration. Most recently, I led the design strategy of business tools and services at JPMorgan Chase, and previously led design systems and major initiatives at Buildertrend and CoConstruct.
My experience has taught me how to balance the details that make a product intuitive with the larger strategies that make it successful.
"During our time together, Than solved complex design problems with an analytical and systematic approach, and a keen attention to detail. He played a key role in reimagining the settings page, and the entire site navigation. He was a crucial link between a future vision of the platform, and working with designers and developers to standardize the building blocks."
Keara Buckle
Director of Product Design, Buildertrend
"Than was a design leader on a small team, and took the lead on impactful user research projects, product enhancements, and our Shibui Design System. His contributions to our product quality were instrumental in positioning CoConstruct for acquisition by Buildertrend. He consistently demonstrates a meticulous approach to UX design, ensuring that every detail is carefully considered. This attention to detail greatly enhanced the quality of our projects and contributed to their success."

Jason Hilton
Director of Product Design, CoConstruct
"Than pushes design excellence beyond where most people think it ends. He passionately blends form and function together in a way that not only elevates the vision of what a product can aspire to, but tactically improves the customer experience in the present moment. Time and time again I've seen his ability to bring designers and stakeholders together in a way that ensures we're all paying attention to the details that make a difference while also keeping the overall vision in focus."

Justin Golownia
Design Lead, Buildertrend
"Than and I collaborated on dozens of projects and I can honestly say that he is the most insightful, thoughtful, talented designer that I have ever worked with. He loves and cares about design more than anyone I know. He posses a special ability to focus on users and their experience relative to his work."

Outside of work, I’m raising three wonderful daughters with my wife in Philadelphia. We’ve recently road-tripped across the U.S. and spent time living in the U.K.—experiences that deepened my appreciation for great cities and public spaces. I play guitar and mandolin, love pickup basketball, and have a lifelong fascination with urban design and the power of community.
