This document discusses financial modeling and valuation for startups. Financial modeling is a tool to forecast a company's future financial performance and understand the relationship between operations and finances. It helps with bottom-up financial planning, evaluating sustainability, and understanding cash flow needs. To do financial modeling requires a detailed business plan projecting at least 3 years of numbers and costs. Valuing a startup considers factors like recent growth records, a step-by-step funds usage plan, addressing a large audience, using technology to scale, solid strategic planning, and successful pilot testing.
