Meet Your Team: Programmatic SupplyDid you know that in-app ads are sold in a real-time auction before they get rendered by adjoe’s Android and iOS SDK in thousands of mobile apps? 
It’s exactly for this that adjoe has built its own adtech platform. Our backend system can simultaneously handle a few billion auctions in real-time every day. It receives price bids for every ad impression via API from more than 20 different companies buying potential ad inventory. 
Behind the auction scenes, we have impressive prediction models working to figure out if an ad is relevant to a user. Our algorithm requires operating data from multiple data sources and performs calculations in real-time. 
Join our discussions, explore implementation, and put your problem-solving skills to the test in our cross-functional Programmatic team!
