John Rush's 100-Waitlist Minimum
Founder John Rush, who has used his idea-to-revenue framework over 20 times, emphasizes a key validation milestone before writing any code. He argues that founders should not build an MVP until they have a minimum of 100+ signups on a waitlist.
Y Combinator's advice to "do things that don't scale" is the foundation for getting early users. This means manually recruiting your first customers, even if the process isn't sustainable long-term, to understand their problems intimately. Founders of companies like Brex attended YC dinners weekly to personally sign up their first ten customers from within the community. To identify early adopters, start by looking for users in niche communities where they already discuss the problem you're solving. Platforms like Reddit, Discord, and specialized forums are goldmines for finding people who are actively seeking a solution. YC Partner Garry Tan emphasizes finding a small, underserved audience to start, as Airbnb did by initially focusing on conference attendees when hotels were sold out. Your cold outreach should be short, personalized, and focused on providing value rather than selling. An effective email is often under 100-150 words and addresses a specific pain point you've identified through research. Mentioning a mutual connection or a recent company achievement can significantly increase response rates. The goal of the first email isn't to make a sale, but simply to start a conversation and get a reply. A successful outreach strategy often involves offering something for free without immediate expectation of a return. This could be a helpful resource, a free trial without requiring a credit card, or even a personalized demo video showing how your tool could work for their specific website. This approach builds trust and demonstrates your product's value upfront. Structure your outreach to make it about the recipient, not about you. Instead of listing your features, explain how your solution can help them achieve a specific, desirable outcome. For example, frame it as helping them get more of a desired result while avoiding a common pain point. Building a consistent pipeline for discovery calls requires tracking your outreach metrics, such as open and reply rates, to understand what messaging resonates. YC Partner Gustaf Alströmer notes that even with a 50% open rate on 500 emails, you might only close two customers, highlighting that early traction is a numbers game. The key is to continuously iterate on your approach based on the feedback you receive. When someone doesn't seem interested, asking "why" can lead to invaluable, honest feedback that helps refine your product and your pitch. YC founders are often advised to talk to their users relentlessly, not just for validation, but to deeply understand their evolving needs. This constant feedback loop is more critical than any growth hack for long-term success.
