I would like to thank you for writing the book. It really helped me to understand the field. Thanks Lillian.

Fahad Masood Reda, Online Educator

Highly recommend.

Sean Chavez, Head of Enterprise Applications

This instructor explains clearly and effectively. I’ve tried to learn the same topic from some other instructors, but they weren’t as good.

Abtin J., Smart Home

Absolutely fantastic. Clear instructions, effective presentation style.

Catherine Schmitt, SAS/R Subject Matter Expert, Data Scientist, published author, IT Systems/Analyst

This product helped me capture outward-facing recognition from peers and leaders within my firm, making me feel like my opinion matters in the direction of the company.

Roman Damaso, Founder

(Lillian) showed a sharp acumen in identifying our target audience and then engaging members of that audience so that they connected and began exploring our offerings. On average, our online community growth rate and our social reach increased by 4-fold during the time Lillian rendered growth and services.

This course covers a lot! Thank you 🙂

This step brings me closer to a deeper understanding and application of artificial intelligence and its use in the product management profession, focused on data-driven decision-making and automation. The course includes practical examples with multiple approaches that showcase how to adapt sales, marketing, and trade marketing operations to leverage specific technologies for analyzing trends and making more accurate, actionable predictions.

Jose Pineda, Executive Director

Excellent instruction. Easy to follow and practice.

Ping Yu, Professor

It’s been 14 months since joining and I finished the (first) year with $100k in revenue – and based on where I am going right now, I should hit $100k this first quarter.

Jordan Goldmeier, CEO @ Anarchy Data

Great tutorial and instructor.

林彥宏, 區經理

This book is awesome! It breaks down the info in the best way possible.

(This book) by Lillian Pierson is a 364-page educational book that is well-formatted, and Pierson’s use of charts, graphs, and pictures helps the reader further understand the material. The book certainly covers a wide variety of topics. The variety of subject matters covered in the book makes the text fun and interesting to read. I believe that an introductory guide to a subject should follow two almost paradoxical rules: it should be easy enough for a beginner to understand, but also contain enough rich and engaging information for the beginner to truly learn something about the subject and set a good foundation for additional studies on that subject. Fortunately, (this book) follows both of those rules; the content is easy for a beginner to jump into, but the book is also thorough enough to really educate the reader about data science.

(This book) is for those who need high quality information in a condensed but easy to digest approach. I’ve found this text to be the most widely approachable book and collection of content for those interested in getting started in the field and reviewing its most important tenets and ideas. While you won’t use this book to become a world expert, it will get you on the right track for your journey.

We partnered with Lillian to develop content and social media promotion in support of an integrated marketing campaign. We are very excited at the success of the campaign and the increased awareness in the market. She was truly a pleasure to work with!

Danielle Scherer, Director of Marketing Programs @ BMC Software

This so far the best training I have done on LinkedIn Learning. I am only halfway there, but the structure (Lillian) and the content are really great. The “Chapter Quiz” at the end of each chapter are practical exercises that will challenge you to find the answer, exactly how a quiz is supposed to be! This is ideal for someone who has very little knowledge. I will be attending Part 2 for sure. Great course!

Lefteris Ioannidis MSc, Power BI Developer

The course is well-taught, practical, and accessible, making it a valuable resource for practitioners. Highly recommended for beginners.

Kioko Munyao, Payments Officer

We hired Lillian to increase sign-ups and participation for our Dice Hack It activation. She was one of our top that we worked with. We were extremely satisfied with her performance and the outcome.

Dice, Technology and Engineering Recruitment Company

Book = Guiding Compass for all, The Author = Genuinely wants you to succeed, So much that I had trouble and she contacted me directly, More details below!!! She explains every general and detailed aspect and her website is loaded with content and HERE IS WHAT IS MOST IMPRESSIVE! YOU HAVE A BOOK WRITTEN BY AN AUTHOR WHO CARES FOR YOU AND GENUINELY, GENUINELY WANTS YOU TO FIGURE WHERE YOU BELONG AND OFFERS EVERY RESOURCES SHE HAS TO GET YOU THERE.

KAZ MEO

I LANDED A DEAL WHERE I EARNED $750K FOR WORK THAT I WAS ABLE TO DELIVER IN LESS THAN 2 WEEKS… Working with Lillian felt like true advisory. She quickly unpacked the core issue behind a 45-item to-do list, helped me refine my vision and positioning, and gave me a quality-first path to attract the right niche. I finally embraced the business, got genuinely excited to build again, and could clearly see my growth trajectory.

Anonymous, Founder

Great course, very insightful and practical.

Samuel Bonney, Research Analyst

Very clear explanations with practical examples.

Alistair Mackenzie, Web Developer

Simple, practical, hands-on and a clear conceptual introduction.

Giancarlo Benvenutto, Ingeniero de ventas

Your advice and willingness to share your process has been a major influence and I am SO VERY GRATEFUL.

Heather A. Smith, Founder and Head of AI Strategy @ JILLCOPR, Inc.

(This book) is surprisingly comprehensive – and not an easy read. But the first three chapters give an effective overview of the subject requiring little or no background. The writing is excellent, serious without being stuffy, but free of the sometimes excessive cornball humor other Dummies books have. The “part of tens” – often throwaway – is full of genuinely useful links to a variety of data visualization tools and resources. I learned a tremendous amount from this book and plan to keep it close at hand as my own job increasingly takes on (relevant) aspects and projects.

I’m learning data science for new projects I’m developing for work with marketing and sales. Recently I read and went through around 10 books on the subject. I found yours by far the best. It was comprehensive, but not overloaded with too many details. For someone starting in the field, it was a great way to get oriented with the well-organized way you explained everything.

Kip Stringfellow, Director @ Strategic Partner Relations at Singularity University

I wanted a little refresher. I found this book very informative. There’s a little bit of everything, a lot of information packed in this little book! It doesn’t go into great detail, but gives a good, brief overview with technical jargon that will be sure to impress your co-workers

It’s a 40% increase in pay. Not too shabby. I calculate my ROI for Clients and Caviar at 45X from completing the course.
