Jampp is the programmatic platform of choice for the fastest growing on-demand companies worldwide.

We solve the most complex and large-scale technological challenges on mobile advertising today. Jampp handles over 50 billion ad requests and process 100 terabytes a day, across three global data centers. We rely on real-time machine learning models (with billions of features) that give us predictions in less than 100ms.

We’re a team of builders - engineers, data architects, designers, and entrepreneurs - who love what we do.

We serve a global customer base from our offices in San Francisco, Berlin, São Paulo, Singapore, and Buenos Aires.


About Jampp

Our Story In 2013 we noticed the chaos surrounding mobile performance advertising, and wanted to change all that, somehow. It took us a year to build Jampp. What we recognized back then resides at the core of everything we do today: real value in this industry is derived from long-lasting app customers, and nothing else. While companies flocked to sell app installs, we designed our infrastructure and technology with a single mission in mind - to help companies boost their mobile sales. Today Jampp uses advanced developments like Predictive Bidding to serve a global client base from offices in San Francisco, London, Berlin, São Paulo, Cape Town and Buenos Aires. We are a diverse team of 80 people with backgrounds spanning Engineering to Economics, delivering sales and engagement to the world’s fastest growing app companies.
