Meet the vibe coders who want to be the 'MrBeast' of apps
Software engineers Los Touré and Marc Mueller have launched a startup called Danger Testing, where they create 'vibe-coded' apps designed for social virality rather than traditional metrics. They identify as 'appstars,' treating software development as a creative performance medium similar to content creation.
Why it matters
This highlights a shift in the tech industry where developers are prioritizing cultural relevance and social media engagement over traditional software utility or monetization.
Los Touré and Marc Mueller founded Danger Testing and are coining a new class of content creators: appstars. Laila AnnMarie Stevens for BI Los Touré and Marc Mueller, two software engineers, call themselves a "boy band." They're not making music. They're making apps . "It's app music, not rap music," Touré, whose legal name is Carlos Mayers, told me at his startup's office in downtown New York City . Danger Testing — which is something between a tech startup and a performance art project — has become Touré and Mueller's full-time business. After meeting at a tech party in 2024, well before "vibe coding" was a buzzword, the two formally joined forces in April 2025. Since then, they've dropped more than 50 apps. Some are wonky websites, others are interactive mobile games. Touré and Mueller are both 26 years old and live in New York City.
