Replatforms that actually moved the conversion number

Replatforms that actually moved the conversion number

Six picks, all with measured outcomes and the team that ran them. Curated, not dumped.

— 1. A DTC brand's headless cutover — moved Shopify to a headless front end on Hydrogen; mobile LCP went 4.1s to 1.8s and checkout conversion rose 12%. The Core Web Vitals before/after is the meat.
— 2. Calendly's pricing-page test — single annual-toggle redesign lifted paid starts 9% with zero new traffic. Read if you think pricing pages are 'done.'
— 3. Ramp's onboarding-funnel rework — cut steps from 9 to 5, activation rose 18% in 30 days. The step-removal logic generalizes well.
— 4. A SaaS replatform off WordPress — to Astro, shaved 600KB of JS and recovered an estimated 7% of organic clicks lost to slow pages. Skip if you're already fast.
— 5. Gusto's form-field reduction — dropped 6 fields, signups up 11%, lead quality flat. The 'did quality drop?' analysis is the honest bit.
— 6. A marketplace's image-CDN swap — to a smart-format pipeline; bandwidth down 45%, no visual regression. Essential if images are your weight.

That's the stack for this week. Forward to a teammate.
