From idea to shipped product, or fixing what's already live.
Karisu works with startups and small teams who don't have design expertise in-house. Whether you're starting from nothing or fixing what already exists, I plug in as the product design function you need, exactly when you need it.
Most teams start with Fractional Product Design, my flagship service and the best entry point for ongoing support.
Fractional Product Design
Embedded product thinking, without the full-time hire.
From €3,000 / HK$27,000 per month
For startups that need ongoing product design support without hiring full-time. I work inside your process, in your tools, as part of how your team ships, not as a one-off handoff. Covers product strategy, UX research, user flows, mobile-first UI design, design systems, and ongoing iteration.
MVP Design & Build
From idea to a live product, designed and built.
From €6,000 / HK$54,000
For founders with an idea and nothing built yet. I take it from concept to a working, deployed product, designed and built together. Covers product discovery, mobile-first UI design, brand foundation, and launch support.
Web & Launch
A premium website, without needing a full product team.
From €1,500 / HK$13,500
The accessible entry point, still built mobile-first and to the same standard as everything else. Covers brand identity, mobile-first website design, fast responsive builds, and launch and deployment.
Product Optimization
For products that need improvement, not a full rebuild.
From €2,000 / HK$18,000
A focused, scoped engagement targeting specific UX or conversion problems. Covers UX and mobile UX audits, conversion review, interface refresh, and usability fixes.
