The Challenge

Blue entered one of the most competitive ride-hailing markets in Europe, where two dominant players controlled 95% of the market. The goal was to acquire users and gain initial traction despite:

  • Limited marketing budget with no historical performance data
  • No internal growth systems to support scaling
  • High install-to-ride drop-off, meaning installs weren’t converting into revenue

To succeed, Blue needed a strategy for profitable user acquisition, frictionless onboarding, and repeatable systems that could scale to new cities.

The Approach

Cross-Channel Paid Acquisition Setup

A high-efficiency channel mix was established, combining Apple Search Ads, Meta, and Google. Budgets were allocated strictly based on performance data, and top creatives were promoted while poor performers were cut quickly.

  • Capture high-intent iOS users through Apple Search Ads
  • Run weekly systematic creative testing sprints
  • Scale Meta and Google with high-performing lookalikes and precise geo-targeting

Creative Engine & Content Iteration

To keep CPI low over 12 months, a content engine was developed to test new value propositions and scale winning USPs. This enabled Blue to continuously refresh creatives, prevent fatigue, and maintain performance even during retargeting.

  • Test and benchmark hundreds of ad variations
  • Introduce new hooks and messaging themes weekly
  • Adapt winning creatives for multiple placements and formats

Activation & Retargeting Campaigns

Many users downloaded the app but didn’t complete a ride. Personalized retargeting and activation flows were launched to boost conversions through focused offers and incentives.

  • Target dormant users with deep-link CTA campaigns
  • Offer value-driven incentives to encourage first bookings
  • A/B test onboarding copy and push notification sequences

The Results

User Base Growth: 35K → 375K+

Aggressive performance marketing, ASO improvements, and retargeting built a strong, scalable user base.

CPI Reduced By 70%

Despite rapid scaling, cost per install remained stable through continuous creative testing and iteration.

Activation Rates Improved Significantly

First-trip conversion rates rose through targeted offers and improved post-install journeys.

Key Takeaways

Creative Iteration Is A Long-Term Moat. 

Constantly refreshing USPs and messaging helped maintain low CPIs.

Acquisition Alone Isn’t Enough

Campaigns focused on first bookings turned installs into real value.

Growth Is Never Guesswork. 

With the right processes, scaling city by city became repeatable and reliable.
