If you’re making $1,000 MRR, you’re not behind — you’re already in rare territory. - 90% of startups fail. - 10% die in the first year. - 70% don’t make it past year 5. - Only 40% ever turn a profit. - Just 10% make it long-term. You’re already in that 10%. Forget the $10k,

Another guy just went viral on TikTok and gained users just using slideshows. Crazy how the images barely changed, it was the hook that did all the work. Props to him. 👏

Just crossed 2M views on another TikTok video. I posted it back in March over 2 months ago and it’s still growing. That’s the magic of organic traffic: it keeps working even when you forget about it. 😄

Someone asked me how much the total fees are after platform cuts. Here’s the breakdown: - 📱 App Store + Google Play: $14.2k revenue (15% fee) - 🖥️ Web (via Lemon Squeeze): $5.2k revenue (5% fee) - 💰 Profit after store fee + ops: ~$16k That’s an 82% margin on $19.5k total

Some of you DM’d me, I didn’t ignore you 😅 I get way too much spam + X DMs have been bugged lately. I literally can’t see anyone’s messages 😂 I think the X backend devs need to patch this soon 😌

My approach is similar, but it's much cheaper for indie developers or small startups. Right now, I already have around 20–30 videos with over 500K views. If I had to pay KOLs at the rate mentioned above, it would cost $10,000–$15,000 and that's not even counting the videos with

I just discovered something about X — if you follow me, your posts can reach my account even if I don’t follow you back. I’ve seen a lot of posts from people who follow me showing up on my feed 🧐

Learning Meta ads rn, but seeing this guy spend $110K for 868 sales made me wanna quit 😵‍💫 If it were my app ($20/month), that’s just ~$17.6K revenue — massive loss. For an indie like me, it’s really hard to afford that. Right now, my app gets around 3–4K new downloads per day,

4 hours to coding 4 hours to marketing 1 hour to exercising Did this every day for 9 months, and boom, 214k users, 90k$ total revenue, and $19,5k monthly revenue! Keep up good habits, and little wins will start showing up 😌

A lot of people ask why their 1K–2K view videos don’t convert. This guy did get conversions from that range. The truth? You need to test tons of formats until one sticks. High views ≠ high conversions. Engagement rate matters more. Once you find what works for your app —

Don’t just focus on marketing. Make sure your app is actually good, cool UX, low bugs. - Marketing gets you users. - Product quality keeps them. - Great product + great marketing = super growth. - Great marketing + bad product = faster failure. Retention starts where ads

A $100–$300 mistake (+ incoming 1⭐ reviews). At 5AM local time, my Supabase disk hit full capacity. The database went into read-only mode no writes. Autoscaling? Frozen for 6+ hours. During that time, my app couldn’t onboard new users, even though TikTok videos were still

This guy got go viral on TikTok with a B2B app. Yes, B2B on TikTok. I’ve never tried TikTok for any B2B product before, but now I’m seriously considering it for my next launch. Most people write off TikTok as only good for B2C or Gen Z stuff. But if you can crack the right

Yah bro, I actually tried using one phone with multiple accounts like 4 to 6 but I noticed a significant drop in views and engagement. From my experience, 2 or 3 accounts per phone is the sweet spot. If you have more resources, going with 1 account per phone works even better.
