SIXT · Post-Booking Growth Strategy

SIXT wanted to increase incremental revenue per rental by improving the digital post-booking experience and driving stronger upsell conversion across vehicle upgrades, protection products, and add-ons.

The opportunity focused on two key post-booking touchpoints: Self-Service, where customers can manage their booking at any time, and Mobile Check-In, where customers complete key rental steps digitally before pickup and can access upsell offers such as vehicle upgrades, protection plans, and add-ons.

The objective was to define a growth strategy and product roadmap that could improve incremental revenue across the post-booking journey, with a strong focus on experimentation, personalization, and data-driven optimization. The scope included Mobile Check-In, Self-Service, and any new lifecycle touchpoints that could create additional revenue opportunities without changing the initial booking or acquisition flow.

The work required clear problem framing, 3·5 growth initiatives, prioritization by impact and feasibility, A/B testing strategy, personalization logic, wireframes, and success metrics to validate real business impact.

Treat Mobile Check-In and Self-Service as high-intent conversion moments. Funnel friction, payment uncertainty, limited personalization, and missed lifecycle touchpoints are the real growth levers.

A roadmap built on progress visibility, clearer Pay Later / Pay Now UX, saved payment methods, fuel refill price transparency, and Shared Trip / Co-Traveler Access · backed by persona analysis, A/B testing logic, wireframes, and UX, marketing and technical success metrics.

Most rental funnels end at confirmation. Treating the post-booking journey as the funnel unlocks incremental revenue without touching acquisition.
