01 The Problem
Funngro's website had a Lighthouse score of 42 and was hemorrhaging potential users at the landing page. Slow load times, poor mobile experience, and unclear messaging were killing their conversion before anyone signed up.
02 Our Solution
Complete frontend rebuild with Next.js Image optimization, font subsetting, and critical CSS inlining. We rewrote the information architecture from scratch — new headlines, clear value props, and a conversion-focused flow. Every animation used CSS instead of JavaScript.
