CustomerFirst.tech

With great satisfaction, I’m placing in your hands a book that has been in the making for the past two years. It’s the essence of my professional experience, brought together into a coherent whole – I’m happy to finally share the finished result with you.

The title is available globally on Amazon, and you’ll find a direct link to the US store below.

✖ STOP running campaigns. ✅ START scaling empathy.

We are facing the Scalability GAP: Data volumes and customer contexts are growing exponentially, while your teams can only expand linearly. In this environment, the traditional approach of “campaign madness” – overwhelming customers with disconnected offers – is not just inefficient; it erodes trust and burns budget.

To succeed today, you don’t need a better marketing calendar. You need a Personalization Factory.

Customer First, Value Next is the executive playbook for creating an AI-driven organization that shifts from “pushing” products to “serving” needs. This is not a theoretical treatise. It’s a proven strategy for leaders who recognize that in the era of AI, the most significant competitive advantage is maintaining humanity at scale.

Inside this playbook, you will discover how to:

  • ⛔ End “Campaign Madness”: Replace disconnected offers with an always-on, intelligent conversation strategy tailored to the individual.
  • ⚙️ Build the Personalization Factory: Implement the AI by Design & Real-Time by Design architectures (Senses, Brain, Voice).
  • 🧠 Master the CI-RM Framework: Deploy 16 practical analytical tactics – including Next Best Action (NBA) strategies and Incremental Uplift Modeling – to drive true, measured customer-centric growth.
  • 📈 Measure What Matters: Shift from vanity metrics to Incremental ROI, Uplift, and Customer Lifetime Value (CLV).
  • 🤝 Scale Empathy: Use technology not to replace humans, but to augment their ability to serve millions of customers personally.

Who This Book Is For

This transformation requires more than just a CCO. It demands an Executive Team that understands value and risk, aligned with a Data & Tech team capable of building the foundation. This book offers dedicated paths for:

🚀 The Executive Team (CEO, CCO, CMO, CFO)
Understand the vision, the risks, and the Return on Investment. Learn how to measure real value, make the business case, and defend the transformation to the CFO by connecting “trust” directly to the P&L.

📈 Growth & CRM Leaders (Head of CRM, Digital, Marketing)
Translate strategy into operations. Move from “send” to “serve” by constructing the Value Map and deploying practical tactics that choose the best offer for every customer context.

💻 Data & Technology Leaders (CTO, CIO, Head of Data)
Build technology within the context of business strategy. Discover fundamental design principles (AI by Design) and architecture plans that automate Data Science without killing your analytics team.

📣 Technology isn’t just an automation tool. It’s a megaphone for empathy. Put the Customer First. Value comes next.

✉️ Why is the area of a circle π·r² (pi r squared)?

The area of a circle vs a square

$$A=\pi r^2$$

The above is perhaps the best known formula and is also rarely understood. Although the formula for the area of ​​a circle was already known in Ancient Greece, its justification is not easy at all. So it’s a great topic to enrich the “Why?” series.

⭐️ The area of a circle – formula

The area of a circle vs a square

As you can see above – a square and a circle of the same area are not “somehow intuitively easy” related. Moreover, it has even been shown that squaring a circle (a procedure performed using a compass and a ruler without a scale) is impossible! And here comes the brilliant idea with a rectangle. Before I tell you what it is, let’s take a look at what the π·r² formula really says.

The area of a circle - 3+ squares

So there are slightly more than 3 squares of the side r in the circle with radius r.

⭐️ The area of a circle – proof by animation

I worked hard on this animation, I hope you like it. Let me know in the comments 🙂

✉️ Why 0! = 1 (zero factorial is one)?

Scalar Calculator - Why 0! = 1

Recently, I was thinking about various justifications for the definition of 0! (factorial of zero) which is

$$0!=1$$

The assumed value of 1 may seem quite obvious if you consider the recursive formula. However, it did not satisfy me “mathematically”. That’s why I decided to write these few sentences. I will give motivations for the less advanced ones, but there will also be motivations for slightly more insiders.

✉️ Why negative times a negative is a positive?

Scalar Calculator - Negative times Negative

Surely everyone knows that the result of multiplying two negative numbers is positive. The formula “minus times a minus is a plus” or “negative times a negative is a positive” was put into our heads during the early school years. However, the teachers have forgotten to explain why this is the case, and to pass the motivation of mathematicians who defined the arithmetic of negative numbers.

⭐️ Multiplication as a short notation of repeated addition

✉️ User functions definition – the unique convenience provided by the Scalar Calculator

Scalar Calculator - User Functions

Functions for mathematics are what elementary particles are for physics. For this reason, the Scalar Calculator and its mathematical engine, provide the syntax for defining user functions, which is as close to natural as possible. Just enter f (x) = x^2 and you are ready to go. Stay tuned to learn a bit more details! 🙂

⭐ Basic user defined functions

The syntax for defining user functions is as follows.

FunctionName(param1 <, param2, …>) = expression

✉️ Fun fact – Scalar – digits clicks distribution – real data

Scalar Calculator - digits clicks distribution - by digit

After few months of Scalar being present in the Google Play Store, we decided to check what is the distribution of digits (buttons) used by our users directly in the application. Below we present gathered data that say something, but we do not know exactly what. Maybe you will help in the interpretation? Do you see any relation to the Benford’s law?

⭐ Scalar – digits clicks distribution – ordered by digit

The most frequently used numbers are 2 and 5. It is also well visible the effect of multi-use of the digit 0 considering particular user perspective. The digit, that is used the least often, is 7.

✉️ Fractions support in Scalar Calculator

Fractions support in Scalar Calculator

When working with Scalar you can enter numbers in the form of fractions and convert decimal numbers into fractions. This is very convenient because fractions function on a par with other numbers, i.e. they are converted to decimal numbers.

⭐ Entering number as fractions

Entering numbers in the form of fractions is done using the following syntax:
