The Challenge

Blue entered one of the most competitive ride-hailing markets in Europe, where two established players controlled 95% of the market. The goal was to acquire users and build initial traction with a limited marketing budget, no historical data, and no internal growth systems.

But acquiring users wasn’t the only problem. A high percentage of installs were not converting into rides. Without a reliable activation strategy, even cheap installs wouldn’t translate into revenue. To win, Blue needed 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 killed quickly.

  • Apple Search Ads added to capture high-intent iOS users
  • Meta and Google scaled through high-performing lookalikes and geo targets
  • Systematic creative testing sprints run weekly

Creative Engine & Content Iteration Framework

To keep CPI low over 12 months, a content engine was developed to test new value props and scale winning USPs. This allowed Blue to refresh creative fatigue continuously and run high-performing ads even during retargeting.

  • Hundreds of ad variations tested and benchmarked
  • New hooks and messaging themes introduced weekly
  • Winning creatives adapted for multiple placements and formats

Activation & Retargeting Campaigns

A large share of users were downloading the app but not booking rides. To solve this, personalised retargeting and activation flows were launched with focused offers and incentives.

  • Campaigns tailored for dormant users with deep-link CTAs
  • Value-driven incentives to drive first bookings
  • A/B testing of onboarding copy and push notification sequences

The Results

User Base Grows from 100 to 350,000+

Aggressive performance marketing, ASO improvements, and retargeting efforts built a strong user base in record time.

CPI Reduced by 70%, and Held Flat for 12 Months

Despite scaling efforts, cost per install remained stable by continuously testing and iterating on high-performing creative.

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. 

Testing and scaling USPs allowed Blue to keep CPIs flat for over a year.

User acquisition means nothing without activation. 

Campaigns targeting first bookings delivered real value from install volume.

Expansion isn’t guesswork. 

With the right systems, city-by-city scale is predictable and repeatable.
