I wanted to talk to someone who builds vibe coding tool, IDE or similar for a while. Also I wanted to talk to a designer about vibe coding tools.

Seems like we hit a bingo in this one😄

In this episode, we spoke with Vitalik Kotik, co-founder & CEO of SuperApp, a startup building the iOS-native full-stack AI engineer - a tool that designs and builds apps in Swift without a human developer or designer.

Before founding SuperApp, Vitalik spent three years as a product designer at Bolt.

* Unit economics and AI — We talked about language learning apps, and How to estimate unit economics of AI startup. and how they can be around 40–70% profit margins

* The engineering behind AI tools — multi-agent orchestration, context management, and efficiency, which models to pick, development tooling, etc. Would love to hear more on this topic.

* Freemium of tools like Lovable — How VC-funded players subsidize 90% of users while bootstrapped startups must break even fast.
