Case Study: Ballsy (DTC men’s skincare brand) achieves 28% increase in conversion rates with Nacelle (headless PWA provider)

Ballsy Increases Conversion Rates by 28% With New PWA

Ballsy, a direct-to-consumer men’s skincare brand on Shopify Plus, was struggling with high latency and slow page-to-page speeds caused by numerous JavaScript integrations — a Google Lighthouse score of 31 and a 16.8‑second desktop load time — which was hurting conversions. To address this, Ballsy partnered with Nacelle to build a headless progressive web app (PWA).

Nacelle’s PWA seamlessly integrated with Ballsy’s Shopify backend and existing tools (Klaviyo, ReCharge, Postscript, Back‑in‑Stock), reducing site load time to 1 second and page‑to‑page speeds to 42 ms. Three weeks after launch Ballsy’s conversion rate improved by 28%, driven by faster page loads (from 1.6s to 1.0s and transitions from 16.8s to 42 ms), demonstrating Nacelle’s measurable performance impact.
