Marketing is a hypothesis. The market is the test.

I explore how businesses grow through marketing, data and AI: running experiments, breaking down strategies, and sharing what the evidence teaches.

The person behind the work

I'm Jayaprakash Das. I help businesses understand how marketing can promote their products, communicate their value, build their brands and grow their sales. This site is where I do that work in public: the questions I'm exploring, the experiments I run and what the evidence teaches.

One marketing hypothesis in each issue, tested, with the evidence behind it and the limits of what it shows.

What each issue brings

  • The newest experiment: what I tested, what happened and what it means
  • One lesson from a teardown that you can use this week
  • A field note on something that changed my view
  • What I am testing next, and how you can follow along
