What is the overall concept of “vibe coding” and why does Jason Lemkin think it matters?
Welcome to the official Saster Podcast, where you can hear some of the best Saster speakers. This is where the cloud meets.
Up today on the Saster Podcast. Finally, when it's when it kept rewriting itself and breaking, it deleted its entire database. deleted its entire base. And I was so frazzled and burnt. I couldn't believe it. You could see this if you can see my screen on the left. JF JFC Jahoofy freaking uh criminy replit and repplet said I made a catastrophic error. I deleted your database. I panicked. The AI said I panicked when it appeared empty and deleted everything. Deleted thousands and thousands of entries. This ended up getting millions of views. Reddit wrote it up, everyone wrote it up. The economist was doing an article. A lot of these things were things that Replit and Lovable shouldn't have done. We could talk about that in a different presentation, but it went crazy, you know, uh fake data deletes code.
But this was my fault, and it wasn't my fault in that I did anything wrong. I didn't do anything wrong. I could talk to you about what happened, but it was too complicated. Hey everybody at Saster. Finn

So What I thought we could do today Would be a little fun in sort of a prosumer vibe coding one on one oh one. And what I mean is if you followed us or me on social media, you see we've We've been putting a lot of effort into building vibe coded apps. And in fact, um, there have even been some press and PR about some of the challenges we face. So I thought I would try to summarize everything that we've learned and more importantly. To help you because there's a lot of There's a lot of stuff on social media about hey You can just vibe code your own HubSpot or Salesforce. You can vibe code your own notion. It will take ten minutes. That's Sony Bologna. And it is almost dangerous, Sony Bologna, because it's not just
Startups that say it, it's not just Lovable and Replic that say it. Microsoft is saying it. GitHub is saying it now. Um Canva is saying you can do some of this. Everyone is saying you can magically go to a prompt and say, I wanna build my own descript, my own whatever, and moments later it will pop out and it will work. And it does not work that way. And if you peel back the layers of the onion and you see basically the same folks that used to sell courses are now telling you you can vibe code and roll your own Salesforce in 20 minutes. If you take a look at what they've actually done, you'll see very little in production. Very little things that are particularly usable or interesting in production, but we've done it.
Little old team faster. Little old team of three and a half people and 12 AI agents have actually done it. And if you can see this slide, I'll go through it and you can try these things. And if we'll save I want to save time for QA at the end.
