where i’d look for my first 100 users: - reddit for honest feedback - x for building an audience - linkedin for b2b leads - hacker news for technical users - product hunt when the product is ready you don’t need every channel. you need the one where your users already are.

A guy just turned standard home Wi-Fi into a radar that sees through walls. Over 62,000 stars on GitHub for a system that tracks humans without using a single camera lens. It doesn’t just know you’re there. Watch what happens when a person lies down on a bed in another room. The AI instantly maps their exact posture, tracks their breathing, and calculates their heartbeat in real-time. No optical surveillance, no privacy leaks - it just analyzes how your body disrupts ordinary radio waves. The whole thing runs on a tiny $5 microchip. Traditional security requires a direct line of sight and invades your personal space. Now, your Wi-Fi router is a camera that sees through solid brick.

@shiri_shh MRR is a funny metric for something people hopefully buy once. this feels more like a premium wedding service with AI behind it than a SaaS.

$100K MRR app idea: couples upload two photos + how they met, get back a cinematic AI film of their love story across eras. weddings would pay anything for this

@fin465 the 90% reply rate is doing a lot of work here. the actual funnel is 300 texts → 10 demos: 3.3%. still solid, just a very different headline.

talked to a founder who hit $60k MRR at age 18 (yes its real, keep reading) he’s doing something i’ve never seen before with his outbound to get 90%+ reply rates: 1. targets realtors 2. builds a hyper-specific lead list + pulls their cell numbers in Origami 3. TEXTs them "hey is this [name] with [business]?" + throws in some personalization when possible 4. he gets ~290 responses off 300 texts 5. dump the repliers into an auto-dialer that calls 3 at once, pitch a demo live 6. of 50 that answer the phone, turns 10 into booked demos The 18 year old founder here is @adennurie_ (he's super impressive) And he's building all his lead lists with @origamichat -how we met.

@chamath you can stop American companies from buying cheap intelligence. you can’t stop the rest of the world from using it. that’s not protection. it’s a self-imposed AI tax

Chamath Palihapitiya
The leading AI has already forked into two options. A: Closed source American that costs $26-56 per 1MM tokens. B: Open weight Chinese that costs $0.50-1 per 1MM tokens. If you force American companies to spend 50-100x more than their competitors abroad here is what will happen: 1. American companies spending 50-100x will at some point become financially impaired and the stock market will crater. This is the equivalent of the US Government saying we can only buy oil at $800/barrel even when the free market sells the same oil for $80/barrel. 2. In the short term, the revenues of the Closed American Labs may remain hi. But then their revenue will also crater because their customers in the US will be impaired and their customers abroad will have already flipped to cheaper solutions. This would be a terribly self-defeating form of intervention if it were to happen.

SITUATION BREWING: The Trump administration is considering restricting cutting-edge Chinese AI models, with momentum reviving after the launch of Kimi K3, per Axios.

How to become an AI native company: 1. Create a single MCP/API gateway. Let your team connect to your systems. 2. Create a company brain - Connect your static context ("Who are we", "guidelines", "product docs" ) - Connect your hot context (meeting notes, emails, slack, active projects) 3. Create a company harness. Instruct AI on how to interact with your company brain and systems. 4. Onboard your team into the harness. Create a self-improving loop. Let it learn from their work. 5. Create a model-routing layer. Evaluate and distribute work to the right model, at the right time. Remove vendor risk. 6. Build autonomous agents on top of your company harness.

My honest take on @Kimi_Moonshot K3 👀 As soon as I got access to Kimi, I put it through the exact same 3D football stadium challenge I had previously given Claude Fable 5. Fable 5 finished in under an hour. Kimi took almost 3 hours 🥵 At first, that was a very bad impression but i decided to see what's taking it this much of time. It was running E2E tests, validating desktop, tablet, and mobile, taking screenshots, finding failures, fixing them, even adapting for low end hardware and low FPS before moving on. All these that Fable 5 never did. None of it because it wasn't able to run this WebGL app on a headless browser. Kimi also shipped a clean React + Three.js codebase with proper components while Fable, as you might have checked codebase, generated one big HTML file with everything stuffed in. With all of this happening, it felt like I was doing more "Vibe Coding" with Fable 5 and more "Vibe Engineering" with Kimi K3. It feels like it's spending more time making sure the code actually works and easily scalable. Really impressed so far. More Kimi K3 experiments coming soon.

@z0rynx i built something similar for security research: 1,310 notes, 13,649 links, 403 sources. now my agents can search the vault, follow the links and pull the right context on their own. still testing it, but my notes finally feel useful.

A 27-year-old pointed Claude Code at 4,000 Obsidian notes and woke up to an employee he never hired. 6 years of notes. Ideas, half-finished essays, 212 book summaries all rotting in a folder he stopped opening in 2024. Then he noticed something obvious that almost nobody uses. Obsidian is just markdown files, and Claude Code lives in the terminal which means his entire second brain is one cd command away from an AI that can read all of it. So he ran it once, overnight. By 7 AM the agent had crawled every note, linked 340 orphan ideas back into the graph, flagged 18 contradictions between things he believed in 2021 and things he wrote in 2025, and drafted 6 essays from threads he forgot existed. Now the loop runs every night while he sleeps. New note goes in messy wakes up tagged, linked, connected to 3 older notes he'd never have found himself. His daily note greets him with what he was thinking exactly 1 year ago and why he was wrong. Cost of the setup: 1 folder path and a 400-word CLAUDE.md file. No plugins, no Notion AI subscription, no $30/month "second brain" course. People spent a decade building vaults that just sit there. He built one that thinks back.

@ErnestoSOFTWARE 70–80% margins are great, but chasing them too early is how you turn a growing business into a very profitable hobby

Ernesto Lopez@ErnestoSOFTWARE·
Making $2.5k from $10k is criminal you should be aiming for 70-80% profit margins This is how to profit max: 1. Do organic UGC not just ads. → Ads can get you 1.5 to 2x ROI → Organic can get you a 5 to 10X ROI do both, not just 1. 2. Make your onboarding shorter not longer shorter onboardings actually help to optimize your ads users that come from ads are already interested and don't need a 50 step onboarding. they just want to buy. This will help your CPA And find more qualified buyers 3. Have multiple retention offers through the app → you can use notifications → discount paywall → or free trials + discounts inside the app 4. Do everything you can to improve your product If your product is better your retention will be better And so will your ARPU ( average Rev per user) If you can make $2 per user Instead or $1 per user You're making 2x more money If you only look at upfront revenue and not at the important vitals of your app you will be left with criminally low margins on the long run
Will@athcanft

what $10k MRR from an app actually nets: - apple tax 15-30% - ad spend 30-40% - refunds ~2% - api costs, tools... you keep maybe $2.5-3.5k still f*cking great for a solo founder just don't compare your profit to someone's revenue screenshot

I'm 30. I built an AI startup called GojiberryAI to $3.5M ARR. Got accepted into YC. If I had to start from 0, here's exactly what I'd do: 1. Sell it before I build it. No code. Just a simple slide deck (mine was 6 ugly slides) explaining the problem, the solution, the outcome, and the price. I made my first $10k that way, before writing a single line. 2. Pick a painfully specific customer. Not "B2B SaaS." Something like "founders at 20-person SaaS companies about to hire their first SDR." So specific that the right person reads it and thinks "that's me." 3. Start outbound on day one, but only to people showing intent. Not scraped lists. People engaging with competitors, changing roles, raising money, or publicly posting about the exact problem I solve. That's the gap between a 1-2% reply rate and 25-40%. 4. Lead with value, never a calendar link. Send a blueprint, not "got 15 minutes?" Let the resource do the selling, and the trial becomes the obvious next step instead of a pitch. 5. Pick ONE channel and go deep. For us it was outbound first, then Reddit (10M+ organic views), then LinkedIn lead magnets. I wouldn't touch a second channel until the first one was clearly working. 6. Talk to customers every single day. The product doesn't matter until you understand the problem better than they do. Spend 90% of every early call listening, not demoing. 7. Only build once people are actually paying. Then keep it dead simple and price it to sell itself. We landed on $99/mo with a free trial, so the funnel runs without me dragging anyone onto a call. 8. Do this relentlessly for about 12 months. That’s roughly how long $0 to $3.5M took us. Bootstrapped. No outside funding. Most founders don’t lose because they can’t build. They lose because they build too early, sell too late, and quit the channel before it compounds.

found OpenShip, an open-source deployment platform you can run on your own server. it handles CI/CD, domains, SSL, databases, backups, logs and rollbacks. there’s also an MCP server, so Claude Code or Cursor can manage deployments. still early, but worth watching github.com/oblien/openship

Also some thing I forgot to add There's so many things now where I don't even use the app anymore but just generate my own app to do things Like WHOOP, for years I wanted to know the correlation between stuff I do and my workouts and sleep, like going to sauna, or what I eat. WHOOP has a journal but it's practically unusable, I logged sauna for ahwile, then I realized you have to ALSO log the days you DO NOT go to sauna, by hand, every day! Useless So in those cases I just ask Claude Code to build a little web app for me that pulls all my data in from my WHOOP, and what I eat, my @wip logs when I go to sauna, or go tan, or go gym etc. It just pulls all the data in and gives me the answers to questions I have Half the time I don't even use the web app it generates, I just ask it directly stuff I have to find a hotel now for some trips we go, I didn't even go to my own site Hotelist, I just asked Claude Code on my Hotelist VPS server to find me a hotel, etc. So many times where it just saves more time to ask Claude Code directly stuff than try to do it with some startup/company's app That's what I mean, I'm obviously more tech than regular people, but we usually slightly ahead in how we use tools, and if I stop using websites and apps, and just use Claude Code for everything in my life, it's not without logic to think that something like that will be the future for most people And of course it's already happening with Claude Cowork and Codex app which regular non-tech people use My point is that the entire app and website layer is just getting decimated And me being a person who lived kinda in that layer (well more websites ofc to be honest) means I have no clue where it's going to except this, or what a person should do, for the first time, I have no clue The only thing I know is that the superintelligence clanker can't reach into IRL and hardware yet for the next few years at least, and there's lots of stuff there to do that's differentiating, because you need a space, tools, machines, make things, and no you can't generate that in 3 minutes with an AI Blood, sweat and tears are not automated yet by AI, yet!!!!
@levelsio@levelsio

Like good odds I'm wrong but I wanted to write this down: It's pretty clear to me that superintelligence is here and it's more powerful than us and it's moving where things are going now, not humans anymore I don't see many people realize this yet, it feels like that pic I posted the other day, everyone is running after the same carrot which is the AI, thinking they're special, and their work is special and their use of AI is special, but it's really not, we're all mostly making the same slop, I mean it's nice slop, useful slop but everyone is making the same slop And because it's so fast to make things, like people used to spend a year on just building an app, now it's done in hours, it's such an immense change, people send me their projects and it all looks the same, it's useful but it's slop Non-technical people (e.g. the gfs) are now building the same or better things than technical people like us So AI has made everybody is just as capable as everyone else, it equalized everyone in the world, as in everyone can make everything (software, music, images, art etc) now and everyone is equal, at least in the digital realm now And maybe now we're in some odd transitionary time where we have to find out waht the next differentiator is as coding/building/execution isn't one anymore for sure I thought it'd be distribution but who knows, obviously creativity and ideas, but if you can copy a successful apps in an hour, then how does that differentiating work? A guy on here @aporia9n wrote how he increasingly meets founders who blast through apps/products/startups, kind of money grabs, very quickly jumping on a trend, building super quickly with AI, make lots of money quick, everyone copies them, then their margins go to 0%, and they shut it down and go to the next thing, in a way they found one differentiator which is speed That's one way to do it, but it shows how radically things are changing I think For now I think the only ones winning is the AI superintelligence itself and the companies providing the AI
