Y Combinator (YC) emphasizes the importance of setting intentional goals and maintaining extreme focus throughout its three-month program, tailored to the stage of each startup. For companies already selling products, goals are often framed in terms of Monthly Recurring Revenue (MRR), while pre-idea projects like the one described must define goals focused on customer discovery and product development. In this experience, YC provided valuable resources such as group and individual office hours with partners, access to a vast network of alumni, and a collaborative environment among the 260 startups in the batch. The startup in question underwent three significant pivots during the program, initially planning to create a data exchange platform, then shifting to a data integration engine, and finally focusing on managing customer data with an on-premise solution. The iterative process, driven by extensive meetings with potential customers, led to continuous refinement of their product idea, achieving their first-month milestones while highlighting the challenges of the subsequent months.
