In today’s crowded app ecosystem, authentic voices make all the difference. When launching or scaling a product, tapping into Key Opinion Leaders (KOLs) can bridge the gap between awareness and trust—turning content into conversions.
Here’s how we used KOL-driven strategies to accelerate growth for two distinct apps: Cho Noi, an e-commerce platform, and 4English, an educational app.
Case Study 1: Cho Noi — Turning KOL Influence into User Acquisition Power
About Cho Noi
Cho Noi is an innovative e-commerce platform that allows users to trade old products for tokens, combining sustainability with smart shopping.
The Challenge
Launching a new product in the competitive e-commerce space required a comprehensive go-to-market strategy that could:
- Build awareness among young shoppers.
- Rapidly grow the user base within a short time frame.
Target Audiences
- Young people passionate about shopping.
- Tech enthusiasts drawn to innovative platforms and digital solutions.
The Approach
1. KOL Collaboration
To create buzz and connect with diverse audiences, we partnered with five KOCs across different age groups and lifestyle categories.
Each KOC produced authentic, relatable content that highlighted how Cho Noi fits seamlessly into their daily lives, whether through decluttering old gadgets or discovering new items using earned tokens.
These videos were distributed across YouTube and TikTok, maximizing visibility among Gen Z and millennial audiences who rely heavily on peer and influencer recommendations.
2. Paid User Acquisition (UA) Strategy
To amplify the organic traction from KOL content, we chose Facebook Ads as the primary user acquisition channel for the app’s launch phase.
- Campaign Objective: App Installs (optimized for install conversions).
- Targeting: Users interested in online shopping and technology.
- Creative Strategy: We used KOL video reviews—adding a strong “Install Now” call-to-action to combine influencer authenticity with the precision of performance marketing.
The Results
By blending influencer storytelling with data-driven optimization, we achieved:
- 400,000 new users in just two months.
- Cost per Install (CPI): $0.80.
- Continuous, sustainable growth following the campaign’s success.
Cho Noi’s launch showed that when KOL creativity meets paid media efficiency, organic and paid growth reinforce each other, creating a lasting market impact.
Case Study 2: 4English — Using KOL Voices to Power App Discovery
About 4English
4English is a dynamic language-learning app offering games, news, and vocabulary tools to help users enhance their English skills daily.
The Challenge
Despite steady Android adoption, acquiring iOS users proved difficult—a common hurdle for education apps in competitive markets.
The Approach
1. KOL-Driven Creative Storytelling
We partnered with both micro and macro KOLs—including language coaches, education vloggers, and lifestyle creators—to showcase the app’s learning features in a credible, engaging way.
Each KOL demonstrated how 4English fit naturally into their daily routines, helping audiences see real-world benefits through authentic experiences.
2. Multi-Channel UA Optimization
To scale efficiently, we ran campaigns on Apple Search Ads and Google Ads, optimizing creatives and bids to drive high-quality iOS user acquisition.
The Results
- iOS users increased by 50%.
- Cost Per Install (CPI) decreased by 20%.
- Ranked from Top 25 → Top 15 in the Education category on the Vietnam App Store.
- Became one of the Top 3 English learning apps in Vietnam within two months.
Key Takeaways
KOL content isn’t just for brand awareness—it’s a strategic growth engine. When combined with well-optimized paid channels, influencer storytelling can:
- Humanize your app’s message.
- Improve ad performance through authentic engagement.
- Drive sustainable, cross-channel user growth.
Whether launching an e-commerce platform or an educational app, using KOL content across organic and paid strategies creates the perfect synergy between trust, visibility, and performance.
