J Sinclair Studio is the independent web, UX and brand design practice of Joshua Sinclair.
A decade of strategic creative work helping growth-stage companies stand out and convert. Partnerships across Virgin StartUp, multi-year retainers with growing ventures, agencies and independent businesses in music, fintech, sustainability and the charity sector.
Co-founder of an e-commerce brand for the best part of a decade, so I read a checkout and a conversion rate the way an operator does, not just a designer. Working globally from the UK.
