Headless Commerce Replatform
Vantage Retail Group
Vantage Retail is a multi-brand group whose holiday traffic routinely 4x's weekday volume. Their Magento storefront was the bottleneck: slow mobile LCP, a search experience that missed intent, and a merchandising team that couldn't ship a campaign without an engineering ticket. We replatformed the customer-facing experience without freezing the catalog mid-season.
01 — The brief
The challenge
Vantage Retail's monolithic Magento storefront couldn't keep up with traffic spikes during seasonal sales, and keyword-only search was surfacing irrelevant results for over 30% of queries — directly hurting conversion on mobile, where most of their traffic originated.
02 — What we built
The solution
We replatformed the storefront to a headless Next.js front-end backed by Shopify Plus, with incremental static regeneration for product pages and an embeddings-based semantic search layer that understands intent, not just keywords.
