Case Study: QuizUp achieves explosive viral growth and 10:1 organic-to-paid installs with Fiksu

Plain Vanilla Games Partners with Fiksu to Jump Start QuizUp’s Virality

Plain Vanilla Games launched QuizUp, a real-time trivia app that needed both product quality and a strong marketing plan to overcome the stigma around mobile trivia games and achieve viral growth. After a previous app underperformed, the team sought a partner to drive the critical mass of users required for QuizUp’s built‑in social sharing and challenge mechanics to work.

Partnering with Fiksu, Plain Vanilla executed a targeted launch plan, rapid creative and channel testing (video, interstitial, RTB and banners), and daily performance optimization via a shared dashboard. The result was a dramatic lift in organic virality and efficient paid acquisition — roughly $1 CPI for non‑incentivized traffic, a 10:1 organic-to-paid install ratio, 1 million users in eight days, 3.5 million in three weeks, and over 10 million users to date — leading to sustained growth and plans for Android and international expansion.
