Phenomenon Studio vs Clay: overview
Phenomenon Studio
Phenomenon Studio runs a discovery phase before any design file opens, and the people who shape the roadmap are the same people who ship the product. Co-founders Valerii Filimonov and Polina Chebanova started the studio in 2019. It now has 90+ designers and developers working from Dover (Delaware), Tallinn, and Lugano, plus a North American office that Vancouver studio Polyform became in March 2025. The studio reports 624 projects for 311 clients across SaaS, healthcare, fintech, and EdTech, says 92% of those clients come back for more work, and counts $500M+ raised by the companies it has worked with (per company website). The outside checks hold up: a 5.0 Clutch rating across 56 reviews, HIPAA compliance assessed by Compliancy Group, and a 2026 UX Design Awards nomination for Wisdom, a safety app for seniors.
