@michaelhyunkim easy, just cut out the middleman and hire me

does anyone have any recommendations for recruiting agencies to hire talent for tuff startups? getting a lot of linkedin dm’s but most seem like noise :(

@Jibran_05 thx for clarifying ser

@_etherean a lot of views, basically the first creators made the video advertising the app, then the second creator (also part of their UGC program) stitched it and pretended it was something novel or super insightful. both videos went super viral

Instagram Reels pioneers the most insane UGC since it's way easier to go viral on Instagram, I've seen: - UGC creators green-screening other creators from their programs and pretending it's sauce - creators fake screen recording YouTube and having the UGC video inside the "ad" actual insanity on Reels

@everestchris6 claude

My new AI UGC factory setup generates content for my brand 24/7 Claude writes the scripts, Arcads turns them into viral UGC videos. Here's the full setup: One text to Claude Dispatch from my phone: "Generate 3 UGC reels for my brand and log them into Notion." → Cowork drafts 3 scripts in my brands voice → Opens Arcads and runs the whole project itself with a different actor on every reel → Videos generate in the background, I don't have to touch a thing → Everything lands in my Notion Reels Queue already tagged and sorted Reply "Claude" + RT all I'll send you the full setup for free (must be following so i can DM)

@dyah10 will do, you guys really cooked

@_etherean This is amazing! Lmk if you have any feedback

@david_attisaas impressive, very based

🚨DARK SAUCE ALERT (2026 edition) 🚨 mobile app makers really out here running some of the darkest patterns in 2026 and still acting like ethical geniuses here are the darkest ones that still print stupid money until the refunds and 1 star reviews hit. 18 dark patterns to avoid doing (please). doing them lead to insta loss of aura. 1 - roach motel subscriptions — dead easy to sign up, literal maze to cancel. they hide the button so deep you need a map and a prayer 2 - sneaky auto renewals with zero real disclosure. one click and boom youre billed for a year while you thought it was weekly 3 - no reminder push before trial ends. surprise your card just got hit and now you're too lazy to fight it 4 - confirm shaming on cancel flows like “no thanks i hate money” or “i dont want to improve my life anymore” 5 - hidden drip pricing that only appears at the very last checkout screen 6 - prechecked boxes for extra subscriptions data sharing or newsletters during onboarding 7 - forcing a quick 15 minute zoom call before they let you cancel. this one is 100 percent dark pattern and we all know it 8 - fake scarcity and urgency timers that refresh every few minutes like clockwork 9 - disguised ads and native promos that look exactly like core app content 10 - endless nagging popups for 5 star reviews that guilt you until you give in or rage quit 11 - aggressive notification spam and tricky permission walls that trick you into enabling everything 12 - keeping cancelled users in your retained metrics during grace periods so the dashboard still looks pretty while reality burns 13 - basket sneaking — automatically adding extra items or subscriptions to your cart without you touching anything 14 - bait and switch — promising one thing in the ad then delivering something completely different once youre in 15 - subscription traps that turn a supposed one time purchase into recurring billing 16 - infinite scroll designed to keep you doomscrolling and addicted as long as possible 17 - tiny gray text buried deep for manage preferences or cancel while the big blue button says accept all 18 - misleading monthly pricing when its actually billed yearly upfront please note that the "hard paywall" isn't in the list because it's NOT a dark pattern at all. most things we buy in the real world are behind a hard paywall. you wouldn't open a gallon of milk to taste it at the grocery store before buying it.

@mdnlabs @ErnestoSOFTWARE @Jahjiren @maubaron we’re gonna make it

Day 12 of Marketing Kneadly HUGE progress in 4 days. Studying the hell out of articles from @ErnestoSOFTWARE, @Jahjiren, @maubaron, and more. - Maximizing learning from Kneadly - Doubling down on UGC via PostSyncer - Planning next app that aligns more with a deep human emotion Possibly will partner with @anything I started a new notebook to consolidate all my learning. We're gonna make it. We have to make it. Goal: $100 MRR by April 30th 24 Days

@terencebuilds thanks, it’s a bit overwhelming to think about marketing while shipping but once you get some views it becomes addicting

@_etherean The gap between submission and launch is perfect for getting that early user interest.

day 1 of building in public creating screenshots to submit Lua to app store managed to get 22 leads via the site

people were into checking their skin age trylua.app/skin-age

there's a million dollars hidden in your computer all you gotta do is press the right keys to get it

@migueljsalazar 🧼 my bro

@migueljsalazar thank you my brother

AI is the greatest unlock for high agency individuals. Happy to see people I met years ago pivot and evolve with the times. Kevin’s gonna join the field of app-builders leveraging AI for a beautiful MRR sooner than later! Can’t wait to see your thoughts on GTM!

@trebienxyz Only 100k left to go!

@_etherean Let’s gooo!

I built a free skin age tool while waiting for App Store. Snap a photo and check your skin age, takes seconds. Try it: trylua.app/skin-age

Crypto background, now i'm building apps. $0 → $100k MRR. Solo founder, Medellín, building everything myself.
