Built by CRO practitioners,
for CRO practitioners
We've done 120+ audits ourselves. We know the pain of manual research — and we built the solution.
From agency pain to platform solution
Funnex started as a CRO agency. We spent years optimizing ecommerce stores, running A/B tests, and delivering audit reports to clients. And we noticed something: the vast majority of our time wasn't spent on the creative, strategic work — it was spent on manual research.
Pulling data from GA4. Watching hours of session recordings. Cross-referencing heatmaps with analytics. Writing the same types of findings over and over again.
We realized this research phase — which takes 60-80% of agency time — could be automated. So we built the tool we wished we had.
Today, Funnex automates CRO research for agencies, delivering comprehensive audits, A/B test hypotheses, and data-backed insights in hours instead of days.
