Phenomenon Studio vs Onething Design: overview
Phenomenon Studio
A repeat-engagement rate is one of the more honest signals a design firm can offer, because it reflects what happened after the invoice was paid, not before. At Phenomenon Studio, founded in 2019, roughly half of clients return for a second project — a result the firm attributes to keeping the same senior team across strategy, design, development, and post-launch support, rather than handing a project between separate vendors partway through. That team numbers 70+ specialists based in Europe, with legal entities in the USA, Estonia, and Switzerland, working across SaaS, fintech, healthcare, and EdTech. The firm has shipped 120+ products for clients that have collectively raised over $500M, backed by a 5.0 Clutch rating, HIPAA compliance monitored by Compliancy Group, and Nielsen Norman Group UX certification.
Onething Design
What's now Onething Design took its current name in 2015, renamed from an earlier predecessor called Ketchup Designs Studio, so the founding date is treated as approximate. The firm runs out of Gurugram, India with offices in Bangalore and San Francisco, reporting 52–73 employees depending on source. Where most boutiques in this list specialize narrowly, Onething goes wide: BFSI, consumer products, enterprise, healthcare, and automotive all sit inside one team's portfolio.
