About

Hi, I’m Dennis Chernobai.

An engineer who caught the marketing bug and got obsessed with sales, growth and monetisation.

I love marketing people. But their minds run on vibes, intuition and gut feelings. Mine doesn’t. Fifteen years of engineering have permanently deformed my brain. I need to see the system, the numbers, the reason something works. In engineering, “it feels right” is not a valid reason.

This newsletter is my attempt to marry the two worlds. Marketing, sales and monetisation on one side. Engineering on the other. Intuition and systems.

Everything here comes from real products:

• My day job – leading growth engineering at Speechify

• My own experiments, where I share the real numbers.
