Can you build a multi-brand catalogue Magento like THG with shared rails?

Yes, THG (The Hut Group) is Manchester-HQ and runs Lookfantastic, Myprotein, Cult Beauty, ESPA, Glossybox and ~30 more brand storefronts off a shared backend. The pattern translates cleanly to Magento. We build: (1) shared product catalogue with brand-tagged SKUs (so a Cult-Beauty SKU isn't visible on the Myprotein storefront and vice versa); (2) multi-storefront / multi-website Magento setup with per-brand domain + per-brand Hyvä theme + per-brand currency / locale; (3) shared order pipeline with per-brand VAT invoicing into Sage 200 or Brightpearl; (4) shared payment rails (one Stripe Connect account, sub-merchants per brand, unified BACS payout); (5) shared OMS / warehouse with per-brand pick-pack labelling. Klarna + Clearpay + GoCardless wired once, available across all storefronts. Typical timeline: 8-16 weeks for a 4-8 brand build.
