Building a Brain Rot IDE | Clad Labs YC F25

Signal Line

From middle school basketball teammates to Y Combinator founders building the world's first "brain rot IDE," Kevin and Richard's journey is a masterclass in persistence, pivoting, and having fun while building.

We discuss:

• How they met in middle school and reconnected to start building

• Richard's seven YC applications (and why only the last one counted)

• Getting rejected with "I hate this idea" and coming back stronger

• Building to 1.5M users, then pivoting 24 hours before their YC interview

• Why iteration speed matters more than coding speed or sales velocity

• Skipping ad impressions entirely and going straight to user acquisition

• The Chad IDE: integrating Tinder, TikTok, and gambling into your coding workflow

• Hiring two interns during YC and why they took the risk

• Why having fun is their most important metric

• Real advice: sell before you build, just do it, don't overthink frameworks

If you're a startup founder, someone who's applied to YC, or just love hearing authentic stories about the messy middle of building, this episode is for you.
