303 | From ChatGPT to Codex: How AI Agents Are Transforming Marketing and Business Operations with Dan Sanchez

Leveraging AI

June 23, 2026

What if the biggest AI opportunity for your business isn't ChatGPT—but the tool quietly replacing it? While much of the AI conversation has focused on Claude Code and coding assistants, a new contender is changing how business leaders think about productivity, automation, and execution.

Hello, and welcome to the Leveraging AI Podcast, a podcast that shares practical, ethical ways to leverage AI, to improve efficiency, grow your business, and advance your career. This is Isar Meitis, your host. And as you know, in the past few months, we've been taken away by this crazy Claude hype, is everybody was doing Claude Code, Claude CoWork, Claude everything, and it really took everybody away, and people almost started to forget that the real 800-pound gorilla is OpenAI with ChatGPT. And to be fair, they were stuck in a really bad place in the last year, but they've made a lot of changes, and the biggest change that they've done was they launched Codex. And Codex was launched specifically to battle Claude Code, which means it was battled to allow people to write code faster and better. And it became a very good coding tool, and exactly in the same way that Claude Code became a tool for many other things other than writing code, the same exact thing happened with Codex.
So, there's been a huge spike in people that are using Codex for writing code, and in the past few months have been a very big spike in people using Codex for more or less everything else. Now, our guest today, Dan Sanchez, who is also known as Danchez, held a senior marketing position in multiple companies, in multiple industries, always doing really, really cool stuff. How do I know he's been always doing very cool stuff? Because Danchez has been on my previous podcast back in 2022
So it's been four years ago, yeah, March of 22 So four years ago before ChatGPT came out. And even back then he was very knowledgeable. And I was always very impressed with how deep he goes into understanding marketing and also how good he is in explaining the concepts behind these things. And in the past three years, he's been all in on AI and how to use AI to improve marketing. And when I say improve, it's not just doing it faster, it's also doing it better. And in the past few months, he's been doing this with Codex. So we get a two for one BOGO kind of thing in this episode. We're going to learn on how to do marketing with AI. But more importantly, or as importantly, we're going to learn how to use Codex for doing things that are not writing code, which means these capabilities, skills, best practices that we're going to learn today can be transferred to doing anything in business and not just marketing, which is really exciting. And hence, while I'm really, really happy to welcome Danchez back to a podcast, the same podcast, and talk about how to use Codex for business, Danchez, welcome to the show.

Thank you so much for having me on. It's fun to do it a second time, different shows, same people.

**Isar Meitis** (2:32)
Yeah, different show, different topics. You and I have done a gazillion shows for ourselves, for other people during that time. It's, we ran into each other randomly. Again, just a quick story on how this happened. We ran into each other randomly. We both were speaking at Social Media Marketing World. They had this year on AI Business World as a mini conference within the conference. We were both speaking there. We ran into each other in the hall, like, oh, this is so awesome. We learned we're both doing similar things. This is a great opportunity. Again, I'm very, very excited. I'm one of those people that was caught in the Claude hype. I've been probably 90 percent in the Claude universe, other than for some of my clients. I have clients in Gemini and I have clients in Codex, and I have clients in ChatGPT. For them, I obviously do work in those fields, but I'm myself very, very excited to learn from you today.

**Dan Sanchez** (3:16)
Yeah.
I got to say, when I started, I was probably a year after ChatGPT launched, and then I launched my own podcast, AI Driven Marketer, because I was like, this is clearly the future. I have to learn everything there is to know.
We both know that podcasting is one of the best ways to learn, but then document what you're learning for everybody else to come along with you.
I did The Journey just like you. We're both podcasting. I'm interviewing people. I'm showing my own stuff. But about, I don't know, back maybe fall last year, like Claude Code is becoming a thing. I'm just like, I'm just not a Claude guy. I don't really find the code to be good enough for a new, like I know how to do HTML and CSS. I'm good at web design. I set up websites all the time. I'm really good with WordPress and all the stuff. But the code just isn't quite sophisticated for me to be able to do more than maybe simple scripts that I need for websites, that I'm doing manually still.
