The 4-Week Pre-Launch Checklist

YC Partner Gustaf Alströmer stresses that founders must manually recruit their first users, as startups don't take off by themselves. He points to Brex as an example, whose founders onboarded their first 10 customers directly from their YC batch with a very simple virtual credit card, long before they had a polished product. The search for early adopters should focus on those already trying to solve the problem, often with makeshift solutions. These individuals are actively seeking an edge and can be found in niche online forums and communities like Reddit, where they are already asking for advice. The goal is not just to pitch, but to become a credible, helpful member of these communities. Y Combinator's Michael Seibel advises finding your first qualified customers within your personal network. He suggests preparing 4-5 questions to gauge how intensely a potential user experiences the problem; this focus on the problem ensures you're talking to people who are genuinely willing to pay for a solution. Cold outreach for an unknown founder is more effective when it provides value before asking for anything in return. Strategies that get 2.5 times more responses include offering a free high-level audit, sharing relevant data, or creating personalized video messages that address specific pain points. The key is to make the outreach about them, not you. A consistent pipeline of discovery conversations is built by going where your target audience congregates, both online and offline. This could mean engaging in specific Slack communities, attending industry meetups, or even analyzing comments on competitor's product review pages on sites like G2 and Capterra. YC's Kat Mañalac highlights the success of Stripe's founders, who would personally install the software for early customers and observe their usage directly. This hands-on approach of working alongside initial users is critical for iterating the product based on direct feedback and building something people truly want. Ultimately, the early-stage user acquisition playbook is about doing things that don't scale. Founders should be deeply involved in every user conversation, collecting feedback, and iterating quickly. As YC General Partner Ankit Gupta notes, paying customers give sharper feedback, so don't be afraid to charge money early to validate the value of your solution.
