What we said about each
What we said about Milk Interactive
"The work index publishes 17 named app projects for clients including Migros, Swisscom, Coop, ETH Zurich and Sonepar, several carrying dated Best of Swiss Apps awards from 2013 through 2024 (a Master and multiple Golds for Teena in 2022; Gold for the 2024 Uepaa relaunch), and the About page names 11 staff including two partners at a registered Zurich AG.

"The published portfolio runs 65 projects across e-commerce, brand identity, and website builds, with named clients including Polène, American Express, Carl Hansen & Søn, Bang & Olufsen, and Carlsberg, plus mobile work for Magasin, Uniqlo, and Swatch; the award record is documented in depth (Awwwards 2x Site of the Year and 23x Site of the Day, FWA 28x). Case studies read as design-rationale narratives heavy on visuals and strategic framing rather than UX evidence, with no user research…"

Strengths and watch-outs
Both upsides and risks, straight from our editorial assessments.
Milk Interactive
✓ Strengths
- •17 published app projects for named clients (Migros, Swisscom, Coop, ETH Zurich, Sonepar) with dated Best of Swiss Apps awards spanning 2013-2024, including a 2022 Master for Teena and 2024 Gold for Uepaa.
- •Registered Zurich AG with 11 named team members and two named founding partners, plus Swico membership and a Swiss Made Software label.
- •Breadth across native iOS/Android and cross-platform stacks (Flutter, React Native), with one quantified production result published (Uepaa: 120,000+ users, ~90,000 alarms/year).
⚠ Watch-outs
- •Ask for the research and testing detail behind a case study (interviews, usability sessions, iterations), since published pages show features and awards rather than method.
- •Request adoption or conversion metrics for projects beyond Uepaa, as most of the 17 projects list awards but no user or business outcomes.
- •Confirm the rate band and current team availability in writing, since the site states a team of 11 and 15+ years against the directory's earlier figures.
Spring/Summer
✓ Strengths
- •65 published projects with recognizable clients (Polène, American Express, Carl Hansen & Søn, Bang & Olufsen, Carlsberg) and full case-study pages for each, concentrated in e-commerce and brand/website work.
- •Documented award record across multiple bodies (Awwwards 2x Site of the Year / 23x Site of the Day, FWA 28x, Creative Circle Digital Agency of the Year), supporting the premium positioning on craft.
- •Clear business legitimacy: Copenhagen address, phone, email, a stated 15-20 person multidisciplinary team, and named platform competencies (Shopify Plus, Sanity, Webflow).
⚠ Watch-outs
- •Ask for research artefacts and quantified outcomes (conversion lift, AOV, traffic) before signing; the visible case studies show design rationale and aesthetics but no testing or redesign-attributable metrics, which is a gap at a €150-199/hr rate.
- •Confirm Service Design, UX Audit, and Dashboard Design capability directly, as none appear in the site's offerings or portfolio.
- •Verify FinTech and SaaS/B2B experience with reference projects, since the visible finance work is investment/portfolio sites rather than fintech products.
