What has your revenue been to date so far across all of these projects?
George Lampropoulus (0:03)
So to date, I think 225,000.
Chris Koerner (0:06)
In like nine months of building vibe coding apps without any coding experience?
George Lampropoulus (0:10)
Yeah.
Chris Koerner (0:10)
Gosh. Quarter million dollars. Most of that profit.
George Lampropoulus (0:12)
My goal is to hit a million in revenue before 20
Chris Koerner (0:15)
Before age 20?
George Lampropoulus (0:16)
Yeah.
Chris Koerner (0:17)
And when do you turn 20?
George Lampropoulus (0:18)
Turn 20 next April. We did like 8K in the first week, and I was like, holy. My dream was 10K a month at the time.
Chris Koerner (0:25)
Yeah.
George Lampropoulus (0:26)
I didn't think it was gonna go anywhere. I just did it because I wanted to see if it was possible. This is insane. I don't know what I'm doing. I have a full business from software, and I don't know anything about coding.
Chris Koerner (0:35)
Yeah.
George Lampropoulus (0:36)
These two latest apps were able to scale both to 10K in 45 days.
Chris Koerner (0:40)
What did you do in December again?
George Lampropoulus (0:41)
So December we did 30, and then January we did 40
Chris Koerner (0:46)
So we've talked a very specific playbook here, but if someone wanted to go out and start their own app like you've done, what advice would you give them?
George Lampropoulus (0:57)
So I have like three different apps that are generating revenue. The one that generated most of it, technically four, but the one that generated almost all of it up to this date has been wrestle.ai and then-
Chris Koerner (1:10)
Dude, I didn't even know you're a wrestler. This is awesome.
George Lampropoulus (1:11)
Yeah. And then the last two months has been, I've really talked about it publicly, but it's like these two other apps have been launching.
Chris Koerner (1:20)
Okay. You can't just do one thing, huh? I can't either. That's not a knock on you.
George Lampropoulus (1:24)
So, no, the reason I did it was wrestling season ended.
And I have like a full-time job. So the way I got the full-time job is I don't know how to code, right? I built all these apps on Rourke. And on Rourke? Yeah, Rourke. It's like an AI app builder.
Chris Koerner (1:41)
Like Replet?
George Lampropoulus (1:42)
Exactly. So it's like Replet, except it does like Swift. So it does like, you know, Swift is?
Chris Koerner (1:48)
For like mobile iPhone apps.
George Lampropoulus (1:49)
Yeah, it's like fully mobile.
And I built my first app through them. And well, I built my first app called Fight AI, which was like, I just built it for myself and I like, it was like a test app. Then, Restly, I was my first real thing. And from there, I was like posting about them for free, just because I was like, this is insane. Like, I don't know, I don't know what I'm doing. And like I have a full business from software and I don't know anything about coding.
Chris Koerner (2:13)
Yeah.
George Lampropoulus (2:13)
And they reached out to me and me and the founder, we would like talk, I would tell him. Yeah, I would like tell him like stuff I wanted, stuff. We would just like talk about the platform. And he invited me to join the team for their growth team.
So I joined December. It was like, yeah, it was only like, it was like two months into Restly. I was like, I then just fully pivoted into like full time on work. And like when I when I do something, I wanted to go like, I still had focus on Restly. But thank God, in those two months, I was actually able to create some systems. So I didn't have to like work on it that much.
Chris Koerner (2:42)
I mean, it's a different game if you have a job. Like you have a responsibility to give them your 40 hours or whatever.
George Lampropoulus (2:47)
Of course, especially because I was like a founding team member. It wasn't like I was joining like a random, it wasn't a nine to five either. It was like, whatever, like when I woke up to when I went to sleep.
Now I'm actually probably leaving.
Chris Koerner (3:00)
Really?
George Lampropoulus (3:01)
Yeah, which is cool because in the next like, so like the next stage in life, I'm hopefully either, I still have to talk to him, like we'll see. But I'll probably be leaving and then trying to focus on one big business to scale up to like, hopefully, like, my goal is to hit a million in revenue before 20
