Stop Using Generic AI In Your Ecommerce Business
ChatGPT once invented a 20% advertising budget for a founder who hadn't made a single sale yet. Marissa Rodriguez explains why that happens, and what she does differently. Marissa Rodriguez has spent twenty years building and scaling direct-to-consumer brands, first as a fractional CMO and COO, now as the founder of Through Experience, a mentorship platform for ecommerce founders. She talks to Matt Edmundson about the risk of handing serious decisions to generic, industry-agnostic AI tools, and why she thinks the real opportunity lies in training AI on the judgement of people who have actually done the job. She shares how her own email marketing training module grew from six videos to fifty once she tried to capture everything she actually knows, and the moment a founder's P&L came back with a 20% advertising budget that ChatGPT had invented from nothing. Along the way, they cover decision fatigue, shiny object syndrome, and where Marissa tells founders to focus first when they're starting out with AI in their business. 08:22 - Why Generic AI Puts First-Time Founders at Risk 15:40 - Training AI With Her Own Frameworks 29:33 - Decision Fatigue and Shiny Object Syndrome 40:06 - ChatGPT Invented a 20% Ad Budget Why Generic AI Puts First-Time Founders at Risk (08:22) Matt asks Marissa the question she gets most often, what's going wrong for people right now with AI. Her answer isn't about a specific tool or tactic. It's about who's giving the advice. Most ecommerce founders are first-time founders with no deep domain expertise to fall back on, and a generic AI tool doesn't know what it doesn't know. It won't ask the qualifying questions a human expert would, and it will hand over confident answers regardless. Marissa has watched this happen with financial models and P&Ls built in ChatGPT, where the tool makes assumptions about costs and budgets without ever checking whether they're right for that particular business. "Having a generic AI working with you, I think you're gonna end up in a bad place." Marissa Rodriguez Her point isn't that AI is the problem. It's that AI without operator judgement built into it is the problem, and that gap is exactly what she thinks founders need to close. Training AI With Her Own Frameworks (15:40) Marissa began mapping her own expertise into an AI the same way Matt describes doing with SAM, Aurion's internal AI layer built on their own playbooks. She assumed it would be straightforward. She already had a structured curriculum from years of building courses and digital products. It wasn't straightforward. One email marketing module alone, originally six videos and forty five minutes, grew into fifty videos once she tried to capture every exception, every variation by AOV (average order value) or customer path to purchase, every moment she'd normally break her own rule because the context called for it. "It went from six videos to fifty videos, because there was so much more than I anticipated that I actually had to sit down and give it the context for understanding." Marissa Rodriguez That's the gap most generic AI tools skip. The judgement isn't a setting you switch on, it's decades of decisions that nobody writes down until someone asks them to. Decision Fatigue and Shiny Object Syndrome (29:33) Founders are surrounded by noise, Marissa says, a constant stream of other people's wins and warnings on LinkedIn and Instagram, most of it stripped of the context that would tell you whether it actually applies to your business. Her advice is to narrow the focus deliberately rather than chase every new tactic. "There's only three actions a person can take on the internet that matter to an ecommerce business. Click, subscribe, and buy." Marissa Rodriguez Everything else, in her view, is in service of those three actions. Paid ads and content drive the click, email marketing earns the subscribe, and the operations behind the scenes, inventory, reporting, unit economics, make the buy possible. She'd rather be great at a handful of things that compound predictably than good at everything and consistent at nothing. ChatGPT Invented a 20% Ad Budget (40:06) A founder came to Marissa with a P&L that ChatGPT had built for them. It looked complete. It wasn't. The advertising line assumed 20% of revenue, with nothing behind the number, for a business that was pre-revenue and hadn't launched yet. "ChatGPT just made up the paid advertising line. ChatGPT just decided like 20% is what you need for paid advertising." Marissa Rodriguez Marissa's challenge back to the founder was simple, on what basis. A properly trained financial model, in her experience, knows which questions it can answer from publicly available information and which ones it has to ask the founder directly, the weight of a product before it estimates shipping, the likely return rate for that specific category. Generic AI skips the asking and goes straight to the guessing. About Marissa Rodriguez Marissa Rodriguez is the Founder & CEO of Through Experience, a mentorship platform for ecommerce founders.
