Artificial intelligence is no longer a tool for specialists. It is becoming the operating system for modern organizations.

Yet most teams never move beyond experimentation. They write prompts, test chatbots, automate a few tasks, and wonder why transformation never arrives. 42: The AI Builder’s Stack provides a practical framework for understanding how AI capabilities build on one another, from foundational prompting to workflows, automation, knowledge systems, agents, and organization-wide transformation.

The future won’t belong to the organizations with access to the most AI tools. It will belong to those who know how to connect them into systems that learn, scale, and compound.

Dennis Vorobyov is the CEO and co-founder of EltexSoft, a boutique software engineering studio he built from scratch in 2015 to a team of 35–50 engineers. EltexSoft has shipped 100+ projects for clients from early-stage startups to Fortune 500 enterprises, with teams in the United States, Portugal, and Ukraine. He moved his family to Lisbon and reorganized operations while Russia’s full-scale war on Ukraine was ongoing in 2022. By mid-2023 he had reworked about 90% of the company’s workflows around AI. 42: The AI Builder’s Stack is what he learned — a practitioner’s framework for how AI capabilities build on one another, from the first prompt to organization-wide transformation.
