Phenomenon Studio vs Spaceberry Studio: 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.

Spaceberry Studio

Spaceberry Studio began in 2016 as "MainCode Agency," rebranding to Spaceberry in 2020 — 2016 is used as the founding year here since it's the same continuous team and entity. Based in Ukraine with an additional London office, the firm runs 12–50 employees depending on source, selling subscription-style UI/UX design for SaaS, AI, and mobile apps rather than quoting fixed-price projects — one of two subscription models in this list alongside Eleken.
