BUILT FOR THE REALITIES OF STARTUP LIFE.
The bestsellers on data engineering and AI are packed with enterprise theory. This book provides the missing link: the startup context.
In a world where you wear multiple hats, data is messy, and deadlines are unforgiving, rigid corporate best practices fail. This book connects valuable theory to what actually works under the unique pressures of a high-growth startup.
The Startup Reality
The first comprehensive playbook to unite all data disciplines through a single, pragmatic lens. Tackles the make-or-break challenges of building a data foundation for AI.
The First-Hire Advantage
Drawing from hard-won lessons as the first data hire, Piotr Sidoruk shares the unique "insider knowledge" needed for scaling infrastructure from day one.
"We haven't seen the best or the craziest of what AI is going to be able to do. Not only do I think it'll create a trillionaire, but it could be just one dude in a basement. That's how crazy it could be."
