Long-term Shopify Plus partnership for Skull Shaver — Pitbull head shavers, Beast clippers, and Butterfly Kiss women’s lines. Checkout extensibility, integrations, and continuous CRO to scale D2C without sacrificing stability.
Skull Shaver (skullshaver.com) pioneered ergonomic head and face shavers with patented designs across men’s Pitbull lines, women’s Butterfly Kiss, Beast clippers, and accessories. With millions of units sold and high-traffic campaigns, the brand needed a Shopify Plus partner who could ship checkout customizations, marketing integrations, and CRO experiments without breaking peak-day performance.
Skull Shaver’s D2C engine depends on trust, upsells, and campaign velocity. Native checkout limits, third-party tool sprawl, and conversion leaks on PDP/cart were capping growth. They needed Plus-grade extensibility and a team that could iterate weekly while keeping the storefront rock solid under promotions.
