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.
