Built by Engineers,
for Engineers.

Our mission is to democratize system design interview prep. We're breaking down the barriers to give every engineer the tools and confidence to land their dream job at a top-tier company.

From Frustration to a Solution

We've all been there: staring at a blank whiteboard, trying to recall design patterns under pressure. High-quality interview practice was either inaccessible or impossibly expensive. We knew there had to be a better way.

The Old Way vs. The AI-Powered Way

  • Passive Learning: Endless videos and articles with no application.
  • Active Practice: Our platform forces you to design and code, building real muscle memory.
  • Slow Feedback: Waiting weeks for an expensive mock interview.
  • Instant AI Analysis: Get immediate, expert-level feedback on every submission, 24/7.
