How Quantum Workplace Improved Core Web Vitals Without a Site Rebuild
Industry: B2B SaaS / HR Technology
Platform: Marketing website (content-heavy, high-traffic)
The Challenge
Quantum Workplace is a leading employee engagement platform used by enterprise teams. Their marketing site plays a critical role in educating buyers, supporting demand generation, and building trust with HR leaders.
As the site evolved, performance began to lag:
- Mobile PageSpeed scores were inconsistent
- Largest Contentful Paint (LCP) regularly exceeded recommended thresholds
- Slow load times risked reducing content engagement and demo conversions
- Manual performance tuning required ongoing engineering effort
The team needed measurable speed improvements – without redesigning pages or refactoring their stack.
The Solution
Instead of one-time fixes or plugins, WebBoost automatically optimized:
- Critical rendering paths
- Asset delivery and loading priority
- Core Web Vitals metrics across key pages
All optimizations were applied without changing existing code, CMS workflows, or deployment processes.
Results
After deploying WebBoost, Quantum Workplace saw immediate and sustained improvements:
Core Web Vitals score improved from 56 → 94
Largest Contentful Paint (LCP) reduced from 3.7s → 1.5s
User engagement increased by 27% on priority pages
Performance gains remained stable over time with no manual upkeep
