Volta — Funnel Analysis
Business Context
The first project in the discover loop: find where the fictional neobank «Volta» loses users in onboarding. Data is synthetic, seeded generator → reproducible CSV.
Hypothesis
The onboarding bottleneck is the KYC step: the largest relative drop-off among funnel steps.
Data & Method
- Step conversion and absolute/relative drop-off at each funnel step (Sign-up → KYC → Funded → Active).
- Chi-square test for acquisition-channel differences.
- Platform (iOS vs Android) and channel (referral vs paid social) comparison at each step.
Insight
- KYC Complete — largest relative drop-off: 56.6% step conversion (loses the largest share at a single step).
- Registration — largest absolute loss: 2,682 users, 73.2% step conv.
- Referral converts +11.7pp better than paid social.
- iOS beats Android at every step: 13.6% vs 11.7% end-to-end.
KYC is the critical bottleneck. This finding feeds the next project — an A/B test of a KYC progress bar.
Impact
- Onboarding bottleneck (KYC) localized — the basis for the A/B experiment.
- A quantitative baseline across channels and platforms for growth prioritization.
