Ask Phill

In short

Ask Phill is an Amsterdam agency on Keizersgracht that does one platform: it is a Shopify Plus Platinum Partner and says it has moved more than 200 brands onto Shopify. Design, theme and headless development on Hydrogen or Next.js, integrations and retention email sit with the same team, and every project opens with a discovery audit of the existing stack. That migration depth earns it #5 on our Shopify list.

Its cases deal with structure more than surface. American Eagle Europe moved off a managed custom platform onto Shopify Plus, with American Eagle and Aerie sharing one theme across ten markets and staying Shopify-native rather than headless so merchandisers could work without engineers. Obey now runs three brands from one codebase, and Naked Copenhagen's sneaker store migrated more than 15,000 products with bot protection for limited drops.

Mid-market and enterprise fashion, lifestyle and beauty brands in Europe that are replatforming, or running several brands and markets on one setup, are the right fit; Patta, Pas Normal Studios, Suitsupply and Stokke are on the list. A small store that needs a theme adjusted would be overbuying, and brands looking for identity design should hire a branding studio before calling Ask Phill.
