Built an AI study note tool → 260k users, $19.7K/month 🤙 https://notewave.app, Learn how I market my app all organic 👉 https://orgatok.co/ → $8k/month

Some people think “building in public” means: – Sharing marketing strategy – Explaining your business moat – Posting roadmap + retention data – Dropping your OPENAI_KEY 💀 Bro, it’s not “leaking in public.” It’s sharing the journey, not the secrets. Build in public. But…
The harsh truth about growing on platforms like X, Tiktok? You gotta speak fluent normie. Genuinely helpful tweets? They flop unless you sugarcoat them in dopamine and make them scroll-stopping. Some of my most valuable posts? Underperform like crazy. Meanwhile: “Use this AI…
I’ve been a dev for 6 years. Used to laugh at people building products with AI. “Real devs don’t need shortcuts,” I thought. I believed in hard work, not cheap hacks. But now? AI helps me write 90% of my product. I’m vibing with Cursor + Claude daily. Shipping faster than I ever…
Unpopular opinion: It’s actually easier to build 10 products doing $10K MRR than one beast doing $100K MRR.
Unpopular opinion: If your “boring” app goes viral, makes money, and gains users it’s not boring. It’s brilliant. Boring is building something no one uses. Not the thing quietly printing cash. Sometimes the most “unsexy” ideas win the loudest. Because boring solves real…
Motivation: “Let’s build an empire.” Discipline: “Let’s build that button you said you’d do 3 days ago.” One gets you hyped. The other gets you paid.
Honestly, I feel like B2C apps are way easier to grow and monetize. I've seen tons of them scale to crazy MRR $100K, $300k even $1M+ (just look at Cal AI, Jenni AI, QUITTR, Rise). Way more than most B2B tools ever reach 🧐
You don’t feel stressed because you’re working, you feel stressed because you’re stuck doing nothing. True freedom isn’t escape. It’s control.
In 2025, the playbook is simple: – Build for Gen Z – Post daily on TikTok, IG & Threads → You win. Gen Z doesn’t care who you are. They just want their problems solved and content that doesn’t feel like marketing. Make it real. Make it fun. Make it shareable. Great product +…
Opportunity doesn’t show up out of nowhere. No one knocks on your door saying, “Hey, this idea is great, you should build it.” No one DMs you saying, “Here’s 100k users, take them.” - You build from scratch. - You post, you ship, you fix bugs. - You pitch your product one person…
You can spend months designing the perfect product… …but no one cares until it’s out. Most of the time, done > perfect. Ship fast, get real feedback, improve fast. Perfection is a moving target. Speed is leverage. The fastest way to build a great product? Ship a bad one,…
Startup life isn’t glamorous. One day you hit a new milestone, the next day you’re fighting a massive bug. Some days users flood in, some days no one logs in. You brainstorm at night, answer support emails in the morning. You’re the dev, the marketer, the customer service…
AI is crazy right now, just like the crypto wave. Those who ride it early and leverage it well will win big. But the real unicorns? They’re the ones who stay in the game the longest, just like the tech companies that survived the dotcom crash. Early mover advantage is real. But…
Nvidia CEO Jensen Huang just made the boldest prediction of his career: “AI will create more millionaires in 5 years than the internet did in 20.” But he didn’t stop there. He revealed exactly HOW it’ll happen Here’s his framework for capitalizing before it’s too late: ⬇️
Just saw a spike in my subscription app today, turns out one of my US TikTok accounts just went viral again. It’s still growing fast 😌

I just added another one, I’ll be releasing one more SaaS this year. Hopefully I won’t end up in the hospital before I launch them all LOL 🤣
This year, I will release 4 new B2C apps.
You came up with an idea. You saw the gap in the market. You thought, “This could really work.” But then you hesitated. – “I’m not ready yet” – “I need to learn more” – “I’ll start when I have more time” – “Let me think a bit more” That’s okay. Just know this: Someone else will…
When you're building something new, talk less. Post less. Silence isn’t weakness, it’s focus. You don’t owe the world updates during your 0 → 1 phase. Validate quietly. Ship quietly. Let your product breathe without noise. But once it’s ready, go loud. Post everywhere. Tell…
I thought hitting $100K MRR organically would be easy. Build something cool. Go viral. Done. Right? Here’s the truth: – $0 → $10K came fast (thank you, TikTok) – $10K → $50K = 10x harder – Now at $16K MRR, growth feels slower than ever Organic growth isn’t free. You’re just…
I quit a $38.4K/year job to chase $0 MRR (failed product), took a $27.6K/year job to survive, then quit again and now I'm running a new product doing $200K ARR 😌
