Based on 11 documented clients · verified Jul 2026

Our Take

Merge Rocks publishes 12+ case studies spanning SaaS, crypto, AI, and healthcare—the Versus Trade project delivered 3,000+ screens with a scalable design system, and ongoing work for Restream (multistreaming SaaS) demonstrates long-term product design partnerships.

At EUR 23-46/hr with a Clutch rating of 4.9 and design award recognition, the studio offers strong visual execution at startup-friendly pricing, though published case studies focus on deliverables rather than documenting research or iteration methodology.

Fast, high-craft product and web design for seed-to-Series-B SaaS, fintech/crypto, AI and health startups (Restream, Owkin, CoinLedger) at startup-friendly rates; case studies show deliverables more than research or iteration methodology, so ask for process artifacts.

Key strengths

  • 12+ published case studies with strong visual execution across SaaS, crypto/fintech, AI, and healthcare—Versus Trade project alone delivered 3,000+ screens and a design system
  • EUR 23-46/hr with Clutch 4.9 rating and design award recognition—strong price-to-quality ratio for startup-stage projects
  • Specialized startup services including MVP development, POC design, design sprints, and pitch deck design—tailored to early-stage product needs

Good to know

  • Published case studies describe what was delivered but rarely document UX research, user testing, or iteration methodology—ask to see process artifacts if research depth matters to your project
  • Portfolio is heavily startup-focused (Angel/Seed to Series B)—if you need enterprise-grade UX process with stakeholder management, confirm their experience at that scale
  • Heavy crypto/Web3 focus in recent work—if your project is outside that space, ask for relevant examples in your domain
