The document discusses various methods for valuing start-up companies, including the asset approach, discounted cash flow (DCF) analysis, and price-earnings ratio. It notes that the asset approach is not suitable for start-ups, while DCF and price-earnings ratio methods are better suited but still difficult given the high risk and lack of financial history for most start-ups. Angel and VC investors typically use valuation approaches that emphasize ownership percentage over precise valuation figures early on, with valuations often in the $1-2 million range for seed or Series A funding.
