Gemini 4 Argon: AI Marketing, 3D Printing and SaaS
The Startup Ideas Podcast
October 15, 2026
In this solo episode, I share what I learned after a week with Gemini 4 Argon, Google's new frontier model. I show three places it shines: marketing with AI, physical AI, and complex engineering, with a real build for each.

I've used Gemini 4 Argon nonstop for the last seven days, and I had to come on and share what I found. You know, most people are going to use Argon just like every other AI, but there are three specific problems where if you just point Argon to it, it can help you build a real business and no one on the internet is talking about it and no one's telling you how to do it. I'm gonna tell you. By the end of this episode, you're gonna know how to use Argon three ways. The first is Vibe Marketing, how to use Argon to get customers to your startup. I truly believe it's the best AI for writing right now and I'm gonna show you how to set it up to write just like you and all the skills and everything. Second, we're gonna talk about Vibe Manufacturing. Argon is really good at helping you design personalized physical products. I'm gonna show you exactly how to do it, all the CAD files and everything. And third, how can you use Argon to point it at legacy SaaS products that people are still paying for and just build a better version? I'm gonna show you that. I'm gonna give away some real sauce around a technique for actually getting customers there. I'm gonna walk you through how I would do it. And I want to give a quick thanks to Google for sponsoring today's episode and giving me early access to Argon. Everything you're about to see I actually built, and these are all my personal opinions. And if you stick around to the end, I'll show you six hacks to get way more out of Gemini 4 Argon than most people will figure out for months. So let's get into it, and I'll see you at the end.
Okay, things to know about Google Argon. What is it amazing at? Well, it's amazing at marketing with AI. So that's important. We need a tool that actually brings you customers. I'm going to show you how to do that and where it's good at it. It's good at Physical AI, AKA Vibe Manufacturing. So how do you take STL files and send it to Bamboo and 3D print it? I'm going to show you how to do that on demand using Argon. And it's good at complex engineering. So I think that you can point it at very legacy SaaS products, add your own spin to it, pick a niche, go even nicher and it could rebuild it relatively quickly. And this isn't Vibe-coded software. It actually is tested, it feels really good.
And I've just been so impressed with how you can actually point it at complex engineering. I want to get this out of the way. Anti-gravity is not my favorite harness. I think that Google has some catching up to do with anti-gravity. And the more I played with it, the more I was missing some of the other harnesses. Now you could still use Argon in your cursor or in other harnesses, open code and stuff like that.
I just wish that anti-gravity would catch up. And I think it will catch up. And I think that one reason I think people should actually pay attention to Argon is Google has so much data and they're making so much progress. And now they're at the frontier level in terms of a model. So let's talk about marketing with AI. I first want to talk about a website me and my team built in 2021 This website took 40,000 hours to build. And it's a website that was built for my holding company. And it just has all the different buildings for all our different companies. Here you see LCA, our design agency, Boring Marketing, which is our marketing with agents company, careers, all this stuff, right? I can't tell you how much money this costs, but I can tell you that the business has probably brought in more than $40 million of revenue and a large part of it has to do with this. It has to do with this website and people always tell us how good their website is. I asked Argon to recreate the website.
Or actually I just said, hey, I want a website like this, but can you make it better basically? And it created this. And it's first of all beautiful. I actually gave it the inspiration for, I was like, make it more Mondrian style, Mondrian the artist. And I think it did such a good job. You know, when you compare it versus the one that probably cost us $200,000 to build, I mean, yes, this is really nice, but it's sad in the sense that there's no cars, there's no movement, and the web, the internet has moved, right? And you want things that are more, you know, that you can interact with. And you can see here, there's this like world passport. When you, you know, click on the buildings, there's some sounds, and like it gamifies going, checking out all the different building, which is what you want people to do when you want to go to their website, right? And I just think there's all these like fun little games and things that you can do. You look, shoot a three-pointer, boom, boom, boom. This is crazy. It is crazy that you're able to create this. And when I say marketing with AI or Vibe Marketing, what I mean by this is, why are you creating a normal website in an Argon age? You know, it doesn't make sense anymore, right? Because you want to stand out. And if you could, you know, how do you stand out? Well, the limit isn't the model anymore. The limit is now the imagination. Because when you have a model this good, with an engine this good, then you can create stuff like this. Now, my first prompt looked like this.
