Journey
At 10 I found a marketing seminar online and signed myself up, and didn't tell my parents until after. My first move was an Amazon affiliate link for my basketball mouthguard, which I sent to friends to try to make a few dollars. Nobody bought it.
In between, I kept busy: basketball, breakdancing, parkour, ninja training, and a lot of other stuff I don't even remember anymore. I read Rich Dad Poor Dad at 12, taught myself to build websites, and made ninja equipment by hand that I sold for a couple hundred shekels.
At 14 I went all in on dropshipping. My first store, Room Service, was me trying to sell room decor. I built the whole thing by hand, back before AI could spin one up in seconds. It never made me a dollar. Then I launched a one-product store, Lockit. I posted a video for it and it hit 200,000 views overnight; 23 people found my Instagram and messaged me asking where to buy, before I even had a working store. I scrambled to finish it and registered a real business so I could take payments. My first sale came in during a water break at a soccer tournament, and for a second, I felt like the richest man on earth. In the end I made about six sales and lost more than 3,000 shekels before I shut it down.
After dropshipping I got into trading. I'm good with numbers, so it pulled me in. I learned the basics on YouTube, bought a course, and traded on demo accounts. I enjoyed it, but after a couple of months I realized trading grows money you already have; it doesn't make it from nothing. I still had my first real money to make, so I left it.
I'm a technical person, so I followed that. I kept seeing people online talk about the automations running their businesses, so I taught myself Make and built a few free automation projects for people. Then I moved up to n8n and discovered AI agents. I built a customer-support agent for someone's Shopify store, and that one project led straight into what came next.
After building that customer-support agent for a client, I decided to turn it into a real product. I already knew from dropshipping that store owners hate doing support, so it made sense as a SaaS. GAGA AI is software that connects to a Shopify store, learns its catalog, and answers customer questions automatically. It finally got me into Claude Code, something I'd been meaning to start for a couple of weeks. To validate the idea I spent $102 on ads to build a waitlist. I built the product in about six weeks and launched it: I emailed the waitlist, and nobody opened it. I ran a second campaign after launch, spending $105, and still nobody signed up. Fixing it meant spending more on ads than I had, so I stopped and decided to build something I could start marketing for free.
I wanted something I could start marketing with no ad spend, so the plan was to start it through viral videos on social media. I love building apps, so I chose a mobile app. This time I didn't want to invent anything; I picked something already proven to make money, with competition, because competition means there's money to be made. That's Caliber: an AI calorie-tracking app for the Israeli market. It's not a new idea, and that's on purpose. The bet is on building it well and marketing it better, growing it from zero. I'm building it right now, getting close to launch.

An AI calorie-tracking app for the Israeli market. I'm building it now, getting close to launch.

I'm Guy, 17, from Givatayim, Israel. For as long as I can remember, I've wanted to build something of my own and do things my own way. I've never liked being told what to do; I'd rather decide for myself and go make it happen. That drive has pushed me from one idea to the next since I was a kid. And I'm completely self-taught. Everything I know, I learned on my own: building websites, automations, AI agents, and apps. Whenever there's something I don't know yet, I just figure it out and learn it as I go. These days, I spend most of my time building with AI.
I'm building Caliber and getting close to launch. But my main focus isn't just the app. It's figuring out how to run the whole business with AI agents. I want agents doing the real work: the marketing, the management, the day-to-day, like a team of employees I built myself. Getting them to actually do reliable work is the problem I'm working on right now.
I share what I'm building, and what I'm learning, on LinkedIn.
