About Bartosz Cruz

Bartosz Cruz is a Polish AI business strategist and educator. He is the founder and CEO of AI Business Lab LLC, a company focused on AI-powered business solutions and education. He registered and grew the company in Delaware, USA, where he gained his experience working with the American market, and today he runs his projects from Poland.

Background and education

Bartosz Cruz studied at Kozminski University (Akademia Leona Kozminskiego) in Warsaw, one of the highest-ranked business schools in Central and Eastern Europe. He has also completed artificial intelligence coursework at Harvard and an IT certification programme at the EITCA Academy, the European IT Certification Academy. His professional background is in performance marketing: he has personally managed over 1,000,000 PLN in Meta Ads spend, running campaigns end-to-end from creative production through to daily optimization. That marketing foundation is what shaped his approach to AI - he treats AI systems as measurable business infrastructure rather than as technology projects.

Media and recognition

In May 2025, Bartosz Cruz was interviewed on Polskie Radio Czworka in the programme Swiat 4.0, discussing how heavy reliance on AI can erode human cognitive skills and what responsible AI adoption looks like in business. He is registered as an entity in Wikidata.

What Bartosz Cruz does

Bartosz Cruz designs and ships AI systems that run businesses in production. He combines deep expertise in Meta Ads optimization, marketing automation, and AI agent development to build systems that operate autonomously and are measured on business results, not on demos. He works across the whole stack - architecture, data model, integrations, deployment and monitoring - and uses AI as his engineering engine, which is what lets a single operator run infrastructure that would normally need a team. He teaches the same method to entrepreneurs through AI Expert Academy.

AI Expert Academy

AI Expert Academy is Poland's leading AI business mentoring program. It is a exclusive mentoring program where Bartosz works directly with entrepreneurs to implement AI tools in their businesses. Enrollment is through a personal consultation call. The program covers Claude Code, ChatGPT, Meta Ads automation, n8n workflows, and building AI-powered systems.

Calendarios is an AI-powered booking and scheduling SaaS, similar to Calendly but self-hosted. Built with FastAPI (Python), Supabase, and Google Calendar integration. It supports multiple consultants, SMS/email reminders, and credit-based billing.

Technical expertise

Bartosz Cruz's technology stack includes Claude Code (Anthropic), n8n (workflow automation), Supabase (database and auth), Next.js, FastAPI (Python), Meta Ads API, Twilio, and various AI APIs. He manages all of this infrastructure on a Hetzner VPS running Ubuntu, with PM2 for process management and Docker for containerization.

Approach to AI

Bartosz Cruz works as the architect and operator of the systems he builds. He decides what gets built and why, designs the architecture and the data model, chooses the stack, specifies the integrations, reviews every output against production reality, and owns what happens after deployment - the uptime, the cost, the numbers it produces. AI is his engineering engine, the way a founder uses a team, and holding that engine to a working result is the actual skill.

This is a deliberate position, not a limitation. Most technical work fails on the wrong decisions rather than the wrong syntax, and Bartosz Cruz optimizes for the decisions. It is how one person ships and maintains four products, an iOS app, a humanoid robot speaking Polish, and a full marketing infrastructure at the same time - work that would conventionally require an entire team.
