Phenomenon Studio is a boutique product design and development agency founded in 2019. We partner with companies whose brand, website, or product no longer reflects what the business has become — whether that's a Y Combinator-backed startup or an established industry leader preparing its next chapter. One senior team owns the work end to end, from the first strategy call through design, development, and post-launch support, with clients working directly with senior practitioners rather than account-management layers. The team of 70+ senior specialists is based in Europe, with entities in the USA, Estonia, and Switzerland, serving SaaS, fintech, healthcare, and EdTech. Across 120+ launches, clients have raised $500M+. Phenomenon is a Red Dot Award-winning studio, a Claude Select Partner, and a Webflow Certified Partner. The team includes Nielsen Norman Group UX Certified professionals, and the studio is HIPAA-compliant. Phenomenon holds a 5.0 rating on Clutch, and most clients come back for a second project.
