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.

As a newcomer, I found this course to be very helpful. The materials are not too difficult to understand because the instructor explains about it in a simple way and provides relevant examples to make the lessons even easier to follow.

Ideas that she presented were worth their weight in gold.
The session helped me with getting clear on priorities. I would highly recommend working with her.
Victor Phillips, Founder @ YUUKI
When we came to Lillian, we were a bit overwhelmed on where to begin creating value from our business data. As a result of our work with her, we’ve developed a strategy and have begun executing upon quite a few valuable use cases. We’ve also arranged our organizational structure in a way that’s much more conducive to the big data projects we plan to develop in the near future.

The methods I learned were helpful to me in leveling up my career.

You might just wonder how much you can actually accomplish in just 1 hour. However when you are on the phone with a marketing + business mastermind like Lillian you can cover a lot of information very quickly. I can easily recommend the power hour to others and if/when I am facing the prospect of making important choices or big moves in my business moving forward I will take advantage of more power hours in the future.

Easy read, great resource!

My favorite chapter in the book is monetizing data and data science expertise. Lillian does a great job at teaching the audience about the methods of turning your data and experience into an income. The book is very comprehensive, and I recommend it for anyone looking to improve their business with data.

I am very happy to have this resource on my bookshelf. It is a must-have and a must-read.

(Lillian’s) expertise enabled her to answer audience questions with ease and generate additional discussion. She was a pleasure to work with. She was very responsive and understanding of our needs. We look forward to working with her again.
Kristin Montalbano, Director, Digital Publicity & Media Relations @ National Geographic Channel
I enjoyed this offer by Ms. Pierson. It is helpful for a peer-teaching presentation I am planning in a few weeks. There was helpful insight around use cases, and the three chapters focused on improving operations, marketing, and decision-making were, to me, the highlight of the entire read.

Fantastic course. Highly recommended for beginners.
Deep Samanta, Ph.D, PMP, Program Manager – Data Driven Engineering
It has been a pleasure working with Lillian Pierson. During her time with us, Lillian brought strategy, structure, and a fresh American perspective to our growth efforts. She has demonstrated an understanding of digital marketing and lead generation, and has consistently been enthusiastic, well-prepared, and professional in her approach. Lillian’s work helped clarify key messaging, including USPS, AI content generation, and email strategies – all of which are critical elements for long-term growth.
Hatla Johnsen, CEO & Co-Founder (Elearning SaaS)
The results and outcomes are incredible. She managed to provide a fundamental knowledge. Her presentation was well-balanced professionally but very friendly. I got great feedback from the audience. Many people would like to listen to her again. And I will definitely invite her again.
Pairach Piboonrungroj, Director MICE Excellence Centre, Chiang Mai University
I enjoyed this book. It’s a great overview of a topic that covers a broad range of disciplines. The author puts emphasis on topics and skills that analysts, scientists, engineers, computer scientists, and data visualization experts use daily. This is a good starting place. Keep in mind this is a Dummy book, so the topics are merely touched on. You’ll have to find other sources for a more in-depth study, but at least you’ll have a better idea of what you’re looking for after reading this.
James W Thomas
Quick, to the point, practical examples and in-depth enough explanations that you can instantly start implementing the content into your own work.
Luke van Eyk, Research Officer
This moderator is excellent: Doesn’t go too fast, or too slow, explains each step and “why” clearly. I feel like I can use the skills learned here immediately to improve my work. Thank you!
