Founder Used 'Shadow Shopping' to Find Problems

- YC Partner Michael Seibel advises finding your first customers within your personal network by identifying people who have personally experienced the problem you are trying to solve; these users are more likely to tolerate an imperfect MVP. - Successful early-stage founders often do things that don't scale; for example, Airbnb's founders traveled to New York to personally meet early users and professionally photograph their apartments to improve their listings. Similarly, Tinder's early growth from under 5,000 to 15,000 users was fueled by its then-CMO personally visiting college sororities and getting them to install the app on the spot. - To find users before you have a product, engage in online communities where your target audience already discusses their problems, such as niche subreddits, Discord servers, or Facebook Groups. The goal is to build a reputation by participating authentically in conversations before pitching your solution. - For cold outreach emails, YC Partner Gustaf Alströmer recommends using plain text with no HTML formatting, avoiding jargon, and clearly stating that you are the founder to build authority. The initial email's objective is not to sell, but to generate curiosity by focusing on the recipient's problem. - To build a consistent pipeline of discovery conversations, product management experts suggest blocking off a set number of hours each week dedicated solely to talking with users. These should be live conversations (video, phone, or in-person) rather than surveys to capture richer feedback. - YC Group Partner Tom Blomfield advocates for a "narrow wedge" product strategy, where founders identify a single, acute customer pain point and build a minimal solution to solve it exceptionally well before attempting to build a broad platform. - When conducting user interviews, a critical rule is to avoid mentioning your idea or product until the very end of the conversation, if at all. Asking users what features they want is less effective; your job is to understand their problem, while their job is not to design the solution. - Charging your first users, even a small amount, is a key YC strategy for validating an idea. According to YC General Partner Ankit Gupta, paying customers provide more honest and sharper feedback than those using a product for free.
