Industry playbooks
Outcomes you can defend in the boardroom
We stress test the flows that matter: onboarding, PDPs, paywalls, and everything in between. Each report links a performance regression back to revenue so prioritization feels obvious.
SaaS & PLG
Measure how onboarding flows behave on throttled networks, then ship guided remediation to keep trial-to-paid conversions intact.
E-commerce
Audit PDPs with inventory-sized imagery, flag personalization scripts that block rendering, and sync fixes directly to merch calendars.
Media & Publishing
Balance ad-monetization with vitals by simulating staggered tag waterfalls and enforcing CLS budgets across every template.
