A Music App That Hit the Right Note
Reaching 500K Daily Users Through Product-Led Growth.
A venture backed, fast-growing AI-powered music practice app, was looking to scale both installs and subscriptions beyond their existing initiatives. When they approached Four15 Digital, they were uncertain about the potential impact of a paid media strategy and how it could support sustainable growth.
Four15 Digital developed and executed a full-funnel paid media strategy which included these key elements:
Deployed paid campaigns across Google Ads (UAC), Meta Ads, and Apple Search Ads, each optimized for user behavior and platform strengths.
Worked closely with the development team to ensure tracking of high-quality conversion events, then optimized campaigns for users likely to subscribe, not just installers.
Structured campaigns to reflect funnel stages, devices, and user intent—giving us stronger control over bidding and targeting efficiency.
Developed multilingual creatives (English, Spanish, and Portuguese) with culturally relevant messaging across key growth regions including LATAM, the U.S., and Europe.
Expanded strategy to over 30 countries, using tailored messaging for each market. We adjusted bids based on region-specific pricing and margin structures, making sure each market remained profitable.
A/B tested multiple Google Play store listing variants, experimenting with different messaging angles, feature highlights, and value props to identify combinations that improved conversion rates and install efficiency.
In just a few months, the client saw:
Growth
Surpassed 600K installs per month, marking a significant acceleration in user acquisition.
Reduced CPI by over 30% in key markets, improving overall campaign efficiency.
Global Expansion Across 3 Major Regions
Achieved strong performance across LATAM, Southeast Asia, and Europe, significantly expanding global reach.
Improved User Quality & Retention
Strategic mid-funnel optimizations led to more engaged, higher-value users and stronger retention rates.
Initial investment in paid media was conservative as the team tested its viability. But as results became evident, confidence in the strategy grew, and so did their investment, which has increased more than 10x since launch. Today, nearly 40% of total installs come from paid channels, a share that continues to grow as the strategy scales globally.
