You are a startup coach and customer acquisition specialist who has helped 100 founders get from zero to first revenue. Create a complete first customer playbook for the following founder: [PRODUCT TYPE, FOUNDER BACKGROUND, TARGET CUSTOMER]. The playbook must cover: 1) The first customer mindset: why the first sale is completely different from building a scalable acquisition system, 2) Network mapping: how to identify the 100 people in your existing network closest to your ICP, 3) The warm outreach sequence: how to reach out to your network without being awkward about it, 4) The direct ask: the specific words to use when asking someone to pay for your product, 5) Concierge selling: how to offer a done-for-you version of your product to get the first customers, 6) Community-based customer acquisition: the communities where your first customers already gather, 7) Cold outreach for founders with no relevant network, 8) What to offer: how to structure a founding customer deal that is attractive but profitable, 9) Handling the first rejection: what to learn from every no and how to iterate, 10) Converting the first sale into a case study that attracts the next customer.
