This presentation provides guidance for early-stage B2B startups with limited budgets on how to validate their ideas before running out of cash. It recommends startups identify their biggest risks, such as customer acquisition volume or pricing, and conduct experiments to test assumptions. For example, a startup concerned with acquisition volume could create a landing page and aim to get 100 free trials per month, while one worried about pricing could seek 5 letters of intent at a $5,000 monthly price. Throughout, it stresses the importance of engaging customers to learn what needs to be built and iterating based on customer feedback.
