Learn More →Keith is a great trainer with solid knowledge and insights in AI. What impressed me most is not just what he knows, but how he's able to apply it in real-world scenarios, especially in ways that make sense for our industry and team's context.
He has a clear and engaging way of explaining things, even complicated concepts become easy to understand. The team really appreciated how quickly they could grasp the ideas and see how they relate to their work.
I also liked the way he ran the training, a good mix of theory, real-life examples, hands-on exercises, and practical implementation. It kept things engaging and meaningful.
Overall, Keith is a rare find when it comes to AI training, someone who not only knows the topic well but can also teach it in a way that clicks.
"I have no complaints at all — a perfect 10 out of 10! I am deeply interested in AI, and platforms like Gemini and Vibe Coding hold great promise for streamlining our daily tasks, from website development to administrative work."
"Treating AI as a smart junior employee with no experience was the most helpful advice. Keith's experience around how to effectively communicate with different agents to get the best out of it is invaluable."
"The exercise levels from Core to Expert helped me go much deeper into the material. The content generation and marketing strategy exercises were particularly relevant to my actual work and easy to apply immediately."
"The best way to learn is to be thrown into the fire. Not watching YouTube videos. I've been there—built companies, failed, succeeded, went public. Now I'm here to help you skip the hard parts."
Follow along as I share what's working in AI, solopreneurship, and building in public.
