About the Author

Pablo Maldonado

Hi, I’m Pablo! I teach data science at companies and universities around the world.

After a few years in consulting (pricing, financial crime analytics, IoT, ecommerce), I decided to focus on teaching others.

Most of my time is devoted to teaching and individual mentoring, but I still do consulting to keep my skills fresh.

Earn $8 on a $10 Purchase, and $16 on a $20 Purchase

We pay 80% royalties on purchases of $7.99 or more, and 80% royalties minus a 50 cent flat fee on purchases between $0.99 and $7.98. You earn $8 on a $10 sale, and $16 on a $20 sale. So, if we sell 5000 non-refunded copies of your book for $20, you'll earn $80,000.

(Yes, some authors have already earned much more than that on Leanpub.)

In fact, authors have earned over $14 million writing, publishing and selling on Leanpub.
