How do you know what their cost base is? I don't quite understand how you'd be evaluating that. Their cost base is largely driven by the LLM and cloud companies. The $25/month pricing feels chosen to be similar to other unrelated SaaS businesses more than something based on a serious pricing analysis.
And the article confirms that, saying they made up a starting price and then immediately lost money due to (doh) selling a product where your costs scale by usage for an unlimited flat rate, which is surely one of the most basic pricing issues out there. And not just for LLMs: they host the apps too, putting them on the hook for hosting costs. They're using a ton of very expensive PaaS services like Supabase to do that too.
Then they have the free tier. Such services often have massive free tier costs; if their userbase is made up of a lot of people just trying stuff out quickly before exporting it to GitHub to continue, that problem will be worse. According to their blog, they have 30,000+ paying customers but there are 25,000 new apps created per day with 1.2M apps overall. So, clearly, almost all apps are being created by free users.
Don't get me wrong, maybe they're printing money like there's no tomorrow, or maybe they will soon. But it feels like the sort of business that's probably burning VC money to buy market share. If their cost base is good then they feel very vulnerable to an OpenAI or AWS releasing something tomorrow that takes away a big chunk of the business, seeing as that's where the bulk of the value lies. Oracle already has something quite similar launched in APEX.
