   I took this course more for Jack’s marketing experience than the AI portion and neither fell short. I loved taking this class and I ramped up my AI skills well beyond what I had imagined. It was a “step function” increase in my being able to harness AI tools effectively. As far as the marketing side goes I started out thinking that I couldn’t market my way out of a wet paper bag with holes in it. Jack changed that for me within 40 days.

   If you are thinking of taking this class, STOP. Just buy the class. You will have all the materials to retake the class again at whatever pace you choose and you WILL want to take this class again.

   I’m a virtual assistant, and I went into the 40-Day ChatGPT Entrepreneurs course partly because of peer pressure. I knew Jack and Tom had put a ton of work into it, and honestly, I just wanted to understand GPT better so I could use it to help my clients.

   I stuck with it all the way through, all 40 days plus the bonus, and I’m glad I did. The turning point for me was learning how to train GPT to actually write in my voice. That one thing alone is worth the price of the course, and I’m already planning to use the same method to build voice prompts for my clients. On top of that, I picked up practical ideas I hadn’t considered before, like creating Mini-Guides and Micro-Services, and I completely rethought my website after letting GPT evaluate it. That one blew my mind.

   What came out of it? A 12-week content plan. New systems. SOPs started. Micro-Services mapped. Mini-Guides in progress. Basically, my whole business is sharper and more structured than it was 40 days ago.

   The only surprise for me was the workload. Jack says 30 minutes a day, and sure, you can do that. But if that’s all you give it, you’ll only skim the surface. I went deeper, and that’s where the real value was.

   So if you’re on the fence? Just do it.

   I worked through the 40-Day ChatGPT Entrepreneurs course while building an email copywriting business. I’ve been running another business for over seven years (and bought it as an established one), so I’m not new to entrepreneurship. I also considered myself better than average at using ChatGPT going in. Even so, I still learned a lot in both areas. That alone made it worth it for me.

   I went through all 40 days (plus the bonus and side quests), and what stood out most was how it opened up channels I hadn’t considered before – like using radio and podcasts for local advertising. It gave me systems, clarity, and confidence I didn’t have going in.

   If you’re on the fence, here’s what I’d say: if you have a business or want to start one, this course will meet you where you are. It’s just as useful if you’re at stage 0 with a brand-new idea as it is if you’re years into an established business. I’ll actually be going back through it again with my other business because it’s that practical and adaptable.

   I run a small science education business (presentations, vocab cards, word walls, and teacher survival tools). I signed up for this course because my husband recommended it, and honestly, I’m glad I listened.

   I actually stuck with it all 40 days, which is saying something. The hardest part for me was not overthinking my website — wanting “perfect” when “good enough” would move me forward. What helped most was the daily structure and learning how to build SOPs (systems for daily, weekly, monthly tasks). That alone shifted my business from an idea in my head to something real that others can interact with.

   The results? Confidence, clarity, and actual traction. Last year I sold 1 product during this quarter. This year, I’ve sold 17 — an 884% increase. I’m not sharing the dollar amount, because for me it’s about progress, not hype. I also feel way more confident posting on social media and exploring new business ideas.

   What surprised me was Jack’s tone. I wasn’t familiar with him before, and I appreciated that the course wasn’t sterile or scripted. The unfiltered conversations with ChatGPT (swearing included) made it feel honest and human — and showed me you can actually talk to AI like a partner, not a robot.

   If you’re on the fence: you’ll get way more value than what you pay for. You could hire a company to do this kind of setup for you, but you wouldn’t learn the skills or build the confidence to keep it going yourself. Am I an expert now? No. But I’ve made real progress, and that’s most of the battle. If you’re willing to put in the effort and do the work, this course will give you tools, structure, and a partner in AI that actually speaks in your voice instead of spitting out generic fluff.

   I signed up for Jack’s 40-Day ChatGPT Entrepreneurs course to sharpen the business side of my brand, The Cynical Dev. I’ve followed Jack for years and trusted that he’d deliver something practical on how to actually use AI for business, not just play with prompts.

   I went through all 40 days and kept up with the Telegram chats. To be honest, it was a slog at times, the amount of daily effort over a two-month duration were difficult to juggle with life demands sometimes, but it was worth it. Seeing the pieces pulled together and watching other people’s ideas come to life pushed me in directions I wouldn’t have gone on my own.

   I came in already publishing and repurposing content, but I left with a much clearer picture of my audience, my ideal customers, and a proper offer ladder that runs from free resources through to consulting and retainers. The systems around all that are sharper now too.

   The course isn’t magic, you still have to put in the work, but if you’re running or starting a small business, it’s highly valuable. Even if you’re not, you could apply the same process to your own career and stand out in your industry while learning how to use AI in a way that sounds like you.

   I rent housing to foreigners on the Caribbean coast of Guatemala, and I also run boat tours. When I moved here from a more established tourist spot, I realized I couldn’t just rely on people already in town. I had to actually attract them to this region. That’s why I signed up for the course.

   I made it a little more than halfway through before other projects pulled me away (building new units, importing a pickup truck, hosting events), but honestly the first half alone was worth it. The focus on defining my business, understanding customer pain points, and setting up a funnel so casual contacts could eventually become clients was exactly what I needed.

   The biggest shift for me was seeing marketing in a new light. I’d always thought of it as something for natural extroverts, almost like magic. Jack broke it down into a set of steps I could actually follow. Pairing that with ChatGPT as a tool was eye-opening. It’s a force multiplier if you know how to use it.

   I walked away with a clearer plan for how to use my website, Facebook groups, and other channels in a way that feels systematic instead of random. Before, I knew the pieces I could use. Now I have a strategy for turning those pieces into a spigot I can turn on when I need tenants.

   If you’re on the fence, I’ll put it this way: I got more than my money’s worth in the first week.

   Quick feedback on the course. The course was excellent and I plan to go through it again. I applied the lessons toward a startup business I’m about to launch. Very helpful on creating messaging and my core message for the service. 

   Improvements:

   – Estimates that the program takes 30 minutes per day are low, especially for a startup business. 
   – Put the main objective of the lesson in the Word and PDF file NAME. Example:

   – 035-GPT-DOCX.docx
   – 035-GPT-Optimize AI workflow DOCX.docx

   – Provide more direction on organizing all the information.

   – “Everyone has a different way to organize information” is true but some people are natural organizers while others need to really work at it. 
   – Some best practices would be appreciated.

   I went into this course as a long-time TSP listener who trusted Jack’s approach and saw this as the best shot at anything close to one-on-one coaching. I’ve been building a homestead-focused business around social media, homeschooling, and DIY self-sufficiency, but I needed direction and a system that fit my world.

   I went through all 40 days. Some days hit harder than others, and I circled back more than once. It’s real work. The first weeks gave me the clarity I’d been chasing for a long time. Weeks 2 to 4 gave me actual execution the push to take action on new ideas and stop spinning my wheels.

   Because of this course, I made and launched my first product. I got it listed, sold it, and started building a real funnel. That wouldn’t have happened without this system or the community around it.

   What surprised me most? I didn’t expect to get this much done. I’ve taken other courses, and they rarely push you this far or make the path so personal.

   If you’re on the fence here’s what I’ll say: You already have access to ChatGPT. That’s not the issue. The real value here is in learning how to ask the right questions from a place of knowing. If you’ve had the tools but haven’t hit your goals, this course shows you why and helps you fix it.

   I’m building a creative humanity business, and I came in knowing very little about business itself. I wanted rocket fuel, and I also wanted to hear Jack’s inspired perspective. I went through all 40 days. Along the way, I discovered some foundational gaps in my own setup — things I had to fix before launching fully. That led me to create 30, 60, and 90-day plans that are already paying off.

   The most valuable parts? Building SOPs, learning how to repurpose a single piece of content across platforms, and creating templates that save me hours every week. The reality check of needing to rebuild my website was tough, but necessary. And honestly, the community of entrepreneurs in the course — sharing encouragement and resources — has been priceless.

   As a result, I now have a clear path forward, systems that actually work, and the confidence to move from endless analyzing into real-world integration and launching. Getting feedback, tracking it, and adjusting accordingly has been a game changer. The pace can feel overwhelming at times — trying to learn a week’s worth of material in 24 hours — but that pressure also pushed me to turn ideas into action fast.

   If you’re considering this course, here’s my advice: don’t treat it casually. Show up like it’s your job. If you want to streamline your business, delegate effectively, and reach a wider audience in a way that actually connects, this is worth it. Honestly, it feels like $10,000 worth of consulting for a fraction of the price.

    I have been dreaming of starting a side hustle for many years, and I’ve also been listening to TSP for just as long. I was one of the folks who “stayed quiet.” Usually, by the time I caught up, the conversation had already moved on to the most recent lesson. Still, being able to read through all the comments from other members was incredibly valuable.

    I went through all 40 days while retiring from a 41-year career in Telecommunications/IT and continuing to run our 3rd-generation South Texas cattle ranch. I couldn’t keep up daily, but catching up on weekends worked fine. I will be going through the course again to polish my results and apply what I’ve learned to the ranch as well.

    What I gained was huge: clarity on how to build a business from start to finish, systems to keep it running, and the confidence that comes from connecting what’s in my heart to what I’m selling. The sales and marketing sections — especially learning how to tie my personal story to my product — were game-changers.

    The biggest surprise? How easy it felt. Short, focused lessons turned my pile of scattered ideas into a clear, logical plan.

    Even if someone isn’t ready to launch a business right now, the insight into how to use GPT effectively is worth more than the price of the course.

    Suggestion for Round 2:
    For those of us who have avoided social media like the plague (or are just so old that we grew up talking face-to-face instead of texting – LOL), a short primer file on how to use Telegram would have made it easier from the start.  My biggest struggles were finding my place after being away for a few days and figuring out how to quickly locate some of the excellent resources mentioned. I understand this wasn’t intended to be a Telegram course, so forgive me if I’m out of line. I did eventually find my way and improved as the course went on.

    Thanks for all y’all have done and continue to do,
