Expand Capabilities To Improve Product Delivery

InboxDollars has long engaged internet users by allowing them to monetize their interactions with online entertainment media. Through its website, users register to receive cash rewards for taking surveys, playing games, and signing up for offers.


The company’s internal developers succeeded in building a positive web experience for users. The arrival of mobile brought new ways to reach more users, but it also posed a new challenge for InboxDollars, which lacked internal expertise in mobile software development. The company needed to expand its development capabilities quickly while maintaining the culture of teamwork that was critical to customer engagement and its product’s success thus far.

“We didn’t have a Mobile app strategy before we started working with MentorMate. To say that MentorMate was influential is an understatement… MentorMate was with us from the very beginning, developing our strategy from the ground up.”

A Dedicated Offshore Team That Feels Internal

Stakeholders at InboxDollars attribute users’ consistent engagement with its services to the high quality of their product, a result of the team’s collaborative approach. Proximity and frequent communication were essential to building a strong web presence. Scaling the team’s capabilities required not only bringing new expertise to the table, but also a commitment to transparency and frequent communication.


Routine visits from a Solutions Architect help to distill stakeholder needs into essential tasks executed by the dedicated team of developers in our Bulgarian offices. While our SA helps to direct efforts as new information is gathered in each sprint, InboxDollars developers are able to troubleshoot in real time during daily meetings with our Bulgarian developers.

“For us to continue to work with a third party when our culture is based on internal development means that... with MentorMate... the cost-benefit is right, the quality is right, and the team fit is right.”

Expand Digital Presence To Engage More Users

Focusing on the technical strategy behind the InboxDollars iOS and Android applications, our developers built and continue to refine application layout and design, security recommendations, SDK integrations, as well as to how the they are positioned on app stores.

“Since we launched our app with MentorMate’s help… we’ve had well over a million people download and install our app in both iOS and Android… We have maintained an average review score... in excess of four out of five stars.”
