Replit

Replit appears in Founder Mode: Paul Graham, Founder, Y Combinator through Paul Graham’s memory of an early AI-coding demo by Amjad Masad. Graham says the demo generated code rapidly enough that Amjad told him not to focus on the emitted code itself, comparing it to object code rather than the thing a human should directly inspect first.

The useful wiki contribution is conceptual rather than a full company history. In this source, Replit helps frame Vibe Coding as a shift from direct authorship of code toward intent specification: English instructions can function like source code while generated code becomes an artifact to run, test, and accept or reject.
