Greg Kowalczyk

Oakville, Ontario

I'm an engineer who builds things. For 14 years at SMS-Siemag (prior PRO-ECO LTD), I led engineering teams on global-scale industrial projects — Chief Engineer, then Manager of Engineering for a 70-person department.

In 2011, I went independent. In 2014, I started building e-commerce brands with my daughter. Two brands, running ever since. Learned SEO, ads, and marketing by doing it — not by reading about it. Spent $2M+ on advertising across Google, Amazon, and Meta.

In 2024, I went all-in on AI. Built custom tools that replaced $75K+ in agency costs. Shipped two iOS apps as a non-coder. Started helping other businesses do the same thing.

Now I build AI systems for businesses that want working solutions, not strategy decks. Everything I recommend, I've tested on my own businesses first. With my own money.

I don't just use these tools — I build custom solutions on top of them.
