/Product Design for Startups
I’m Sam, a freelance senior product designer helping startup founders in the US and beyond turn early ideas into clear, buildable digital products.
Define the right MVP, explore the experience and prepare for development. One senior design partner, from the first conversation to handoff.
/Where I can help
/01 Define the MVP
Clarify who the product is for, the problem it solves and what belongs in the first release. Align user needs with your business goals and constraints.
/02 Explore & validate
Make the idea tangible with user flows, wireframes and interactive prototypes. Test key assumptions with users before committing to a full build.
/03 Design the experience
Turn the agreed direction into clear web or mobile interfaces. Shape onboarding, core tasks and the states people need to use the product.
/04 Prepare for development
Give your engineers organized Figma files, reusable components and interaction details. A practical foundation for the first release and what comes next.
/Relevant work

A focused mobile product for tracking migraines, spotting patterns and preparing medical reports. Explore Keluma for a closer look at the experience.
/From first idea to handoff.
Direct collaboration with your founder team, with a clear scope and regular opportunities to review the work.
/01 Find the focus
We discuss your idea, audience and constraints, then agree on the key problem, scope and deliverables for the first phase.
/02 Make it tangible
We work through flows and prototypes, reviewing decisions together and using feedback to refine the experience.
/03 Get ready to build
Your team gets developer-ready designs and the detail needed for implementation. We can agree on design support as the build progresses.
Let’s give your idea a clear next step.
