challenge
Killi is a mobile app that offers consumers a platform where they can have control of their personal data and sell it directly to brands and agencies, choosing what data to share with advertisers and earning money from it. They are truly a leader in the data privacy space with over 100 million accounts registered in the U.S. As the company grew since its founding, and with their IPO just around the corner, they decided to look for engineering support to complement their in-house talent. They needed to boost their development power to reliably develop new products and improve existing ones, and their in-house team had been working to become a top-notch solution that could close a big acquisition deal. They realized they couldn’t make that deal a reality without some extra help and that’s when they reached out.
solution
We kicked off our collaboration with a small project, which is something we usually propose to new clients to get to know each other and provide value as soon as possible. On the first project, our team worked on improving the performance of their internal tool. The challenge was enhancing the platform’s response time, which negatively impacted the user experience. This tool managed user data in over 800K locations and had become slow with time. After this initial project, we grew from a two-dev team to eight professionals contributing to Killi’s in-house staff, all with different specializations.
results
Our team was a key contributor in achieving many improvements to Killi’s products: a backend migration to boost the app’s performance with Django; their React Native app where users share their data and manage their earnings; the development of Killi’s web app version; custom development of authentication features using Cognito AWS, push notifications with Firebase, and app analytics with AppsFlyer; integration with many survey platforms, providing advertisers with users’ answers, key data for their targeting strategies. In addition to the development power, we also provided team leadership and DevOps implementation for deploying their products around the world. Thanks to our experience working with Scrum, we also brought more agility and fluid communication to the team. All of these positive contributions were key to our client’s expansion and growth, leading to their acquisition by a prominent U.S. marketing agency.
