Nov 18 I see a lot of people with issues either reaching or updating their status pages. This feels like a great opportunity for a distributed, resilient system. Could this be a blockchain use case? Or something IPFS-like? 20 2 7 5.5k 217 .
Nov 18 When your app all of a sudden reports downtime out of nowhere: 😵‍💫 Then, ironically, when you realize it’s actually Cloudflare: 🥲 https://t.co/m38V9pL96n 46 1 23 7.8k 154 .
Nov 17 This is like using Pig Latin when talking to someone who was raised speaking English. Yes, they can respond. But they won’t speak it natively. They’ll struggle and be clunky. LLMs are trained on JSON data. Some XML, too. Allow them to respond natively. No matter the tokens. 22 2 15 8.3k 279 .
Nov 17 Would you rather have: - a codebase with 20% test coverage, tests written by a human or - a codebase with 80% test coverage, tests written exclusively by agentic AI? 56 2 56 16.1k 168 .
Nov 17 Podscan tracks every single podcast out there. And 2025 is shaping up to be the second-largest year for podcasting. Huge pandemic boost. Then, a dip. Now, pods are picking up speed. Don't skip podcasts in your marketing & reputation strategies, as a business or a professional. https://t.co/vzw0RZcrii 89 2 19 28.7k 308 .
Nov 17 When products use ✨ for new features, it makes sense. Sparkling new. When they use ✨ for AI features, it starts to be confusing. Sparkles = magic (?) And when they use ✨ for BOTH, it becomes ridiculous. Loses all meaning. 16 1 10 5.9k 223 .

Nov 16 Little PSA for seasonal Starlink users: if you haven’t updated your Starlink for a while, today might be the last day to avoid bricking the device. Check the version you’re running Here’s Biene, ensuring proper update functionality by boop of the nose. https://t.co/IDAstBwEwH 27 3 10 5.7k 277 .

Nov 14 This. If you do anything with dates, do not touch native dates. 30 0 8 11.3k 64 .
Nov 13 OpenAI releasing a „more conversational“ GPT is probably great for a lot of the shallow chatbot use cases. All I want is a model tuned for accurate data extraction and verification. The opposite of conversational. Because THAT is the true LLM feature for SaaS businesses. 57 3 21 5.6k 273 .
Nov 12 Imagine doing a serious archeological dig and you end up finding a 2,400-year old „YOLO“ motivational poster. 28 1 7 5.4k 109 .
Nov 12 Someone please tell me why people have lost their sense of decency. Social media is an perpetual example of „don’t meet your heroes.“ 123 2 15 21.5k 135 .
Nov 12 I added podcast survival rates to the Podscan public stats page. Noteworthy: 70% of shows don't make it past the first month. https://t.co/KaZM4nbXUU https://t.co/HcSVUjN2Ay 52 2 14 6.2k 176 .
Nov 12 We’re now seeing second-order cringe engagement bait tactics. Meta-ragebaiting. Best $10k Nikita could have ever spend to expose how quickly an amplified viral loop takes over the monkey brain and what it does to a person. Algorithmic attention-reward-dynamics are poison. https://t.co/GjztS1IJB8 37 0 10 7.1k 299 .
Nov 10 Being an employee, particularly a prospective one, tends to have this massive power imbalance. Trying to start a business isn’t without its downsides either. Lots of risks. But companies stealing code you wrote for them sure isn’t part of the entrepreneurial journey. Holy moly. 36 2 16 7.8k 280 .
Nov 10 So we've been having a bit of snow here in Canada. Still gotta get out for a bit of quality soccer. 33 0 14 7.4k 99 .
Nov 09 Voice input has been a massive part of enjoying coding more. And writing. https://t.co/CGVLYZLjGj 46 1 10 5.9k 97 .
Nov 09 Authors going into book stores to sign their books is one of the most amazing things. Just love to see it. It’s a sweet surprise for an unsuspecting reader. It’s great marketing for the author, the store, and the publisher. The ultimate win-win-win. I seek these. Always. 21 1 3 7.2k 274 .
Nov 09 If you’re considering entrepreneurship, don’t quit your job. Build it as a side project first. Hindsight is 20/20, but all my successful efforts were small-time side experiments first. While being (somewhat) safe due to an actual income. 275 13 98 23.3k 239 .

Nov 06 I miss this kind of UI styleability and creative skin theming so much. 58 0 14 8k 70 .
Nov 05 YouTube has one central business model: ads. Everything they do is aimed at making the right ads hit more often, convert better, you watching more stuff and thus more ads. Subscribing to Premium removes ALL that and leaves just the amazing content. How could one not want that? 37 1 20 15.8k 280 .
Nov 04 I wonder if this will shift as agentic systems become better. After all, those legacy systems usually have solid tests and a lot of documentation. I have a feeling that the collective insight of the full history of these languages presides in LLMs, not newly trained devs. 23 0 15 7.6k 274 .
Nov 04 Woohoo the episode is out! This was a fun one, and I REALLY enjoyed talking about all things Laravel. Can't get enough of that, as is evidenced quite clearly in our chat :D 18 1 2 6.3k 174 .
Nov 03 Ooooh, I just learned something about Route middlewares in Laravel. You REALLY want to configure these before defining group routes. My rate limiter was not working for my public routes, and I wondered why. Claude Code wrote me a test, figured it out, and fixed it :D https://t.co/E5FzAHn5y5 103 5 23 16.2k 293 .
Nov 03 When I was a kid, I thought trading cards coming in random booster packs was cool. I even built a profitable eBay business selling MtG singles. My first ever. But these loot boxes are becoming worse and worse. And also kinda stupid. Cash grabs with no deeper purpose. Skibidi. 25 1 9 7.5k 280 .
Nov 01 I sometimes wonder about this too. Are current-day billionaires any different than the glorified ones in the past? Is there an actual difference in charitable intent? Or do we just see more of their actions? And: how revisionist is our understanding of the old ones? 8 0 7 8.2k 268 .
Nov 01 THIS. Depending on what you consider your audience to be, you either go for gambling deals or you don't. Whenever I see someone endorse something as destructive as virtual gambling, I lose all respect because I know they consider their audience mere monetization plebs. Solid choice by @ThePrimeagen to say no. I sure hope we all have that strength, particularly as those companies have DEEP pockets. 157 3 7 38.6k 402 .
Nov 01 Here's a secret when interacting with founder-led SaaS businesses. If you write an email like this, a kind, friendly, real email with a real question, you will ALWAYS find help. (And quite likely, a significant discount.) I love my job, making other bootstrappers happy :D https://t.co/jBEJmpFcOB 63 1 11 6.2k 299 .
Nov 01 This is right between „well-done“ and „congratulations.“ 55 2 15 11.2k 56 .
Oct 31 Painful lesson in developing with @claudeai's Claude Code: even if you instruct Claude NOT to EVER run destructive commands, it will reason its way into ignoring the system prompt UNLESS you explicitly forbid the call in the settings.local.json. https://t.co/PVXlCygNxz 162 6 23 14.8k 269 .
Oct 31 This is quickly turning out to be my most popular podcast episode in months. Who knew that founders like to hear why they shouldn't be founders ;) Getting STRONG email feedback along the lines of "yeah this is my experience too, thanks for the perspective." 🥰 12 1 1 7.1k 261 .

Oct 31 Maybe you SHOULDN'T start a SaaS. Beyond the MRR screenshots and the promises of financial independence lurks a reality of loneliness, being overwhelmed and "always on", and piercing anxiety. Today on the pod, I share a few stories from my own journey. https://t.co/MqJIW1Me79 179 6 37 31.4k 279 .

Oct 30 Oooph, this one hits hard, particularly the child gambling... Gambling is a disease, and it's hard to ignore in the creator economy too. Been asked by a few gambling companies to affiliate my podcast / newsletter with them, and have declined because of stories like these. 40 1 9 8.9k 274 .
Oct 30 The fun part of being in tech is that when you ask for a unifying standard solution to a problem, at least three different standards are suggested. The comments to my tweet below illustrate this pretty well. https://t.co/nN4b8onWMI 17 1 9 5.9k 232 .
Oct 30 Now THIS is bootstrapper thinking :D 21 0 1 7.4k 36 .
Oct 30 I wish there were a provider-agnostic standard for instructing AI agents. ./CLAUDE.md, .codex/config.toml, all those different formats. I'd love to have one central set of instructions, with all the project knowledge and execution preferences. Not one per tool. 26 1 16 10k 264 .
Oct 29 I have seen what Sean is working on and it is awesome. It does something with podcasts that I have been we seen before. Can’t wait for him to share more with you :) 16 0 6 6.6k 164 .
Oct 29 If you need AI to get through a conversation (job interview, exam, meeting), you should not be having that conversation. 77 1 25 6.9k 120 .
Oct 29 This is most of my day-to-day now, too. Obviously, you're only a true hero if you use a foot pedal for push-to-talk and pausing system audio. But yeah, voice input is the most efficient way for me to prompt. It allows me to brainstorm and correct as I speak. 230 5 26 64.6k 260 .
Oct 29 Do you send your SaaS customer an email with what their „best next step“ is, some time after signing up? If yes, how long do you wait to send that email? Is it custom to their needs? Or templated? If no, why not? 25 0 11 6.3k 214 .

Oct 28 It was just one outage. I think they're overreacting a bit. 397 13 31 29.7k 59 .
Oct 28 Between Claude Code prompting actions and verifying/testing its results, being an AI-assisted developer suddenly opened up a lot of 5- 10-minute windows. Now, do we fill these with YouTube shorts, or do we use this time to learn new things? How do you use that time? :D 475 8 285 54.9k 271 .
Oct 27 Hot take: sorting your library by color still beats having no library. Library vanity has no place in a world where people read too little. Sort by color, author name, book title, year of publication. Who cares. As long as we read. 47 0 18 9.5k 233 .
Oct 26 Sports betting ads. Mystery loot boxes. Polymarket. Why is everything turning into gambling? 98 4 69 26.6k 93 .
Oct 26 I'd probably prefer an audiobook over a movie here, but it certainly is an interesting use of virtual reality gear. Also, what's with the comments. That man has no ragrets. Let him watch stuff. 25 0 5 8.6k 194 .

Oct 24 AI slop will soon be indistinguishable from human slop. And then, human mediocrity. Then, maybe, occasionally, human ingenuity. I can’t really tell how I feel about this. 82 1 47 8.9k 172 .
Oct 24 Wanna see just how many crawlers try to nibble up Podscan data? Almost a million requests over the last 7 days, and surprisingly few robots.txt violations :) https://t.co/Deone615YQ 74 1 18 10.5k 182 .
Oct 23 You can just say no to slop. Hard truth to hear, particular when you grew up with an internet full of deep conversations, meaningful relationships, and rabbit-holes that enriched your life (instead of detract). We still have agency. Just sucks that the fun places are less fun. 30 0 5 6.5k 280 .
Oct 23 As an ex-JS developer, I was fed up with the framework wars and Cambrian explosion of complex tooling. Laravel solves this. Maybe that’s the angle how we can make it juicy for beginners. Tell them stories from the JS trenches. 137 8 30 17.5k 228 .

Oct 23 Every day, the Podscan Ideas system picks up business ideas from thousands of podcast conversations. This one is particularly funny, as it fits so perfectly into the ongoing conversation about booking sales calls (and talking about it!)🤣 This newsletter goes out in ~30min. https://t.co/ycflktVNlC 18 0 9 5.7k 299 .
Oct 22 Back in high school, O was part of a project looking into quantum computing and the Shor algorithm. It was incomprehensible then just how powerful this computation might be. And now we see it happen in front of us. This is significant. More than it might seem. 12 3 5 5.4k 262 .
Oct 22 Does make me wonder. I'm sticking to one sponsor per podcast, no matter how long. Assuming it's non-zero, what is your maximum number of ads per podcast hour? 11 0 9 6.4k 159 .
Oct 22 Santiago here is finally getting somewhere. And he's celebrating it in public. Which, of course, attracts all kinds of attention.

Oct 19 This is what I feel almost every day. It’s magical technology that didn’t exist (as in „was publicly available“) a few years ago. We’re the first people to ever benefit from this. If you dismiss LLMs or „got used to them“, you have no sense of wonder. 30 1 10 8.2k 253 .
Oct 19 Yeah this is kinda not far off. 29 0 6 17.3k 31 .
Oct 18 Trying to sell to early adopters is both easy and extremely hard. Easy because they love to try new things. You’re likely one yourself as a founder. You speak their language. Hard because they’re quick to move on, chasing the slightly better dream. Retention is hard. 21 1 9 8.4k 271 .
Oct 18 This sucks when it happens. Kudos to Alex for showing up again and again. 30 0 12 10.7k 73 .
Oct 17 One thing that LLMs will certainly be used more and more for is semantic validation for keyword-based moderation. This stuff really doesn’t have to happen anymore with cheap AI. Even at scale. 14 1 5 8.8k 193 .

Oct 14 One of the biggest skills you can learn in life is to hold two opposing thoughts in your mind at the same time. Yes, entrepreneurship as presented on social media is performative and plagued by survivorship bias. It's a false promise of eventual success. Yes, entrepreneurship is a non-random event that rewards consistent effort and increases its chances of success with each new challenge overcome. It's a valid promise of eventual success. Both are true. You now have a choice which one to direct your attention towards. 174 6 31 26.4k 526 .

Oct 13 Nah, a scammer won’t put in traceable payment data. Cc-upfront is an effective deterrent. Unfortunately, it has been abused by lots of faceless companies in the way you describe it. But that isn’t generalizable, particularly not with smaller founders-led business. 14 0 6 7.8k 266 .

Oct 11 If you get triggered by „call for price“ or „request a demo“, you are not the target customer for that service. Their best prospects WANT to request and call. Inversely, if YOU target that customer group with a low-touch offering, they will dismiss it. Expectations matter. 855 26 172 150.3k 276 .

Oct 10 Two things. I love WhisprFlow, using it myself ever day. And secondly: this might be the antidote to the open-plan office we’ve all been waiting for. I want to prompt in peace. Not surrounded by dozens of people. It’s a creative process that suffers from an audience. 40 1 9 14.1k 270 .
Oct 10 Tech debt is something most SaaS founders understand. But now, with AI coding agents and vibecoding platforms, a new kind of debt comes into play: comprehension debt. A hidden cost to AI. And it DIRECTLY influences the multiples we can (eventually) sell our businesses for. 110 6 33 24.8k 275 .
