Stage 1

Week 1 - Week 2

Collecting Data & Reaching CPA


A/B Test, Collect Data & Reach CPA


For our Mobihunter team, working with banking applications is already very familiar; read also our cases on Monobank and Easypay. Obank client came to us with a request to work on a CPA model, where the target action was an issued card.

Stage 2

Week 3 - Week 7

Increase User Base


Increase the number of cards issued


After the testing stage, we began launching campaigns and developing creatives for Facebook since it was the best traffic source and gave the best results. We promoted the Android application on the UA geo.

We tested a large number of creatives, and on Facebook we had the most conversions from banners, such as:

In the first month of work, we attracted 1,800 new users, with a 5% conversion to card issue. We decided to test other traffic sources.

Stage 3

Week 16 - Week 28

Growth in the Number of New Users and Test New Traffic Sources


Find new effective traffic sources, increase the number of cards issued


At this stage of work, we planned to test new traffic sources or look for new approaches. Previously, Facebook campaigns brought new users. After much testing and working with creatives, we succeeded with traffic from Google.

Of course, we managed to increase the number of attracted users by threefold, and the percentage of conversion to the issued card also increased from 4% to 12%.

Currently, we continue our cooperation, and we plan to expand to larger volumes.


In conclusion, Obank, the mobile banking app offered by Idea Bank, has seen significant growth in its user base and card issuance rates with the help of Mobihunter. Through strategic campaigns and creative optimization, Mobihunter successfully increased the volume of attracted users and improved the conversion rate for card issuance. By leveraging effective traffic sources like Facebook and Google, Mobihunter has achieved remarkable results and laid the groundwork for continued expansion and success in the future. As the partnership between Mobihunter and Obank continues, the focus remains on driving sustained growth and delivering exceptional value to users.
