I think Marc’s post is going to spark a lot of debate. I agree that most of us start with 0 followers. But I don’t think we all start from the same place. Like me: Building a global business from Vietnam is already harder than doing it from the US or Europe. For example, someone in the US can simply create a TikTok account and reach US audiences. Meanwhile, I can get millions of views in Vietnam and barely make any revenue. And trying to reach US audiences comes with the risk of getting shadowbanned. But I also have advantages: lower living costs, cheaper internet, and lower taxes. (But luxury goods and cars cost 3–4x more here 😂) So yes, I still consider myself incredibly lucky, and I’m genuinely grateful for it. We all face different disadvantages, but we also have different advantages.

I've said this many times: Vibe coding is killing the gap between developers and non-technical people. TikTok and IG influencers are realizing they can build their own apps. They already have the audience. They know what people want. $10K–$100K in revenue is now within reach without writing a single line of code. Organic marketing is still king for B2C apps. High revenue. Insane profit margins. Zero ad spend.

I made $53K in October 2026 📱 5 B2C mobile apps — $42K 📢 Marketing services (include X payout) — $11K And ~80% profit margins. (-15% for Apple and Play Store 🥲) Reach ~50M+ views across TikTok, Lemon8, X, IG, Threads, and other platforms. All powered mostly by organic marketing. Still solo. Still finding time to hit the gym every day. 💪

But honestly, if I were in that position, I’d also choose a SaaS built by someone with a strong presence on X, unless there were no other alternatives. When founders have a personal brand, they’re more likely to provide better support. You can simply tag them on X instead of waiting forever for a response from some faceless company where you don’t even know who’s behind it 🫠

It's true that vibe coding can build a profitable SaaS. But the guy who built it, Marc, has 419K followers on X alone, not even counting his audience on other platforms. And let's be real, most of you guys don't have that kind of audience. (me too) 😌

Some people might find this hard to believe, but I actually only use Cursor (for internal tools and backend) and Rork (for mobile apps and games). I barely use Claude Code, even though I have a Claude subscription. 😌

Some guys say AI content doesn’t work. Today, I randomly came across a fitness channel that’s 100% AI-generated. They’ve already started building an app and are using that same AI channel to market it. They went viral before even launching the app. And with a direct CTA like this, I bet their conversion rate will be pretty damn good.

Violating NSFW policies can get your app banned from both the App Store and Google Play. Character AI just filed for bankruptcy despite generating $5.3M/month in revenue ($2.8M MRR from subscriptions) and having millions of users. Lawsuits, tighter regulations, and massive operating costs brought the company down. A reminder: Even a huge AI company isn't immune to legal and platform risks.

My game is now 90% complete, with almost all features built. 🔥 30+ real-world businesses, dynamic weather, day/night cycles, and an economy that reacts to them. Added monetization: rewarded ads, season passes, lucky spins, and diamonds to speed up progress. Still free-to-play! Now it’s time to test, fix bugs, and polish before launch. 👀 Built with Opus 5.5 + Sonnet 5.5 for smaller tasks.

Good news for the app builder community! You really can get support from both the community and Apple. Keep going! And do your best to comply with Apple’s TOS. We’re here to build sustainable, long-term businesses, not just make a quick buck.

Some guys commented that the mobile version was completely broken, with UI elements getting cut off or covered. With just one prompt using Opus 5.5, I updated the entire UI to be fully responsive, fixing the layouts and adding proper support for both mobile and iPad. 🤯
