This document provides guidance on how to reverse engineer a SaaS company by asking penetrating questions. It recommends taking time to research the company using Google, then creating a presentation that analyzes the company's idea, prototype, customer acquisition, scaling operations, competition strategies, and other stages. The example of Freshdesk is used, with questions like why it was started, the initial consumer insight, how it got early customers, and how it scaled while retaining culture. The goal is to understand other companies' journeys and avoid reinventing solutions by learning from their experiences.
