Jinsu Kim
Product Designer / Berlin
A product designer based in Berlin, designing fast-growing B2B SaaS products for 5 years.
I specialize in designing complex zero-to-one initiatives at fast-paced B2B startups. Instead of adding features, I focus on making impact and measuring it based on data—for example, a sixfold increase in paid plan conversion rates through reducing the time-to-value in the onboarding flow.
I design with a holistic perspective, considering both business stages and technical aspects. With deep knowledge of web design patterns and technical implementation, I excel at solving complex problems in a clear and visually appealing way. My data-driven approach extends to considering CRUD data cycles while designing and communicating with my team through data.
