Product design where hardware, software,
and people connect.

Product design where hardware, software, and people connect.

No matter where the starting point—an idea, a prototype, or a live product—support is tailored to meet specific needs. From defining the vision to refining the details, the approach adapts to fit the project.

Integrated hardware/software experiences

HW/SW Experiences

User interfaces are designed for hardware-connected systems, blending on-device UX like screens, LEDs, audio, and haptics with digital ecosystems. Prototyping ensures seamless interactions, while design systems provide consistency and scalability as products evolve.

Discovery, strategy, and roadmapping

Discovery & strategy

Strategy sprints and roadmap development define actionable plans to bring visions to life. Prototypes and design frameworks guide exploration, aligning on opportunities to validate concepts and chart a clear path forward.

Hold Fast Studio is the independent design practice of Kevin Korpi, a Bend Oregon-based designer, writer, and product strategist.

I've spent well over two decades obsessing about product design, working with teams at GoPro, Moment, Contour Cameras, Microsoft, Amazon, and Google, plus dozens of startups and agencies across Japan and the US. My sweet spots? Hardware/software integration, AI interfaces, consumer tech, B2B apps, and health & fitness products.

I've tackled everything from 0-1 products to refining experiences used by millions. What gets me excited is teaming up with forward-thinking folks to build stuff that matters. To me, design isn't some mysterious art—it's about solid collaboration and getting things done.

Whether you're sketching ideas on napkins or innovating at enterprise scale, I bring a practical, hands-on approach. Having worked from Tokyo to SF to Seattle to the mountains near Bend, OR, I'm comfortable jumping into any team setup.
