Welcome

My name is Max Pumperla and I’m an entrepreneur, engineer and educator from Hamburg, Germany. What I enjoy most is building & shipping interesting projects and writing about them. With more than 15 years of professional experience, I can help you realize your projects, too.

My primary focus is on building companies I want to own and run, with people I value, solving problems I care about.

My holding unbounded ltd. currently builds the next generation of language learning apps at lingonook, brings meditation practice to the German market at ganzda, and helps teachers save valuable time spent on corrections at gradefast and schnellkorrigiert. Our goal is to provide value and build fully bootstrapped companies that are profitable from day one.

If you need advise on building your startup or think I should invest in it, reach out to me. In case you seek a technical partner and already have an audience or community, I might be interested in partnering with you.

If you already have a startup operating in the AI/ML space, chances are I can help you grow it. My consulting work is centered around solving complex data science and engineering problems, as well as technical writing. As an engineer, I specialize in deep learning and its applications and I can build ML solutions and data products from first prototype to production. I’m a prolific open source contributor, author of several machine learning books, speaker at international conferences and Coursera instructor. As Ray and DL4J core developer, Keras contributor, Hyperopt maintainer and author of a range of open source libraries, I have a distinct view on machine learning engineering and the data science ecosystem.
