As the platform continues to grow, Fastic remains focused on expanding its reach and unlocking new monetization opportunities.
Challenge
Fastic aimed to broaden its distribution strategy and access new customer segments in Germany and Romania, especially outside traditional app store ecosystems. A major challenge was the limited availability of alternative billing models that could provide a seamless and localized payment experience for users.
Solution
Mondia partnered with Fastic to address these challenges by enabling integration with major telecom providers, O2 Germany, Vodafone Germany, and Orange Romania. This strategic collaboration allowed Fastic to extend its reach through:
- Carrier Billing Integration: Seamless Direct Carrier Billing enabled Fastic users to subscribe via their mobile phone bills, removing friction at the point of purchase
- Localized Offers: Mondia supported Fastic with customized offers designed for telco audiences in Germany
- Efficient Onboarding: A smooth and well-supported technical integration process ensured Fastic was quickly up and running across both platforms
Results
The partnership delivered strong early traction, with increases in both registrations and paid subscriptions across O2 Germany, Vodafone Germany, and Orange Romania. Mondia provided Fastic with a valuable acquisition channel, allowing the brand to diversify revenue streams while enhancing customer accessibility.
Conclusion
Fastic’s collaboration with Mondia marks a successful step toward expanding its user base and monetization strategy in Germany. By tapping into Mondia’s telco expertise and carrier billing capabilities, Fastic has been able to unlock new audiences while maintaining a user-friendly experience.
With this foundation in place, Fastic is well-positioned for further growth across additional telco partnerships and markets.
