Kunal Verma and William Ferguson never imagined that coding for fun would one day become more than just a pastime. Both developers now independently run their own app businesses, Verma’s XigXag Interactive is a full-time job in India and Ferguson’s XandarMob is a side gig.

Verma’s apps have reached 1.5 million downloads on Google Play, his most popular ones, such as Kids Musical Toys Set, are catered to children. AdMob’s ad content control options are particularly useful for the demographic he serves. Verma’s apps are 100% free with a steady 99.09% fill rate. With AdMob, he makes 3x more income than he would at a regular IT job in India.

Ferguson’s word scramble app, Lexathon, has been translated into 19 different languages and downloaded 430,000+ times by a loyal user base that spends an average of 10 minutes on the app per day. AdMob Mediation allows Ferguson to maximize his fill rate and leverage multiple ad networks to increase his total revenue.

Toni Fingerroos, a games developer in Finland, became inspired to create a mobile app. He devoted 3 months to building it, often working 16 hour days. That idea became the hugely popular Hill Climb Racing, and the game has grown to be part of a successful app business called Fingersoft.

Hill Climb Racing has been downloaded in over 145 countries on both iOS and Android. AdMob consistently generates nearly 100% ad fill rates and enables Toni to monetize the game on a global scale. He uses AdMob house ads to promote his app too.

“Hill Climb Racing has over 60 million downloads. About 40% [of the revenue] comes from advertisements, and AdMob is our cornerstone,” says Toni. Hear more about Toni’s story in the video below.
