Why price-to-sales ratio matters to a first-time founder
This ratio can compare public companies that have revenue but little or no profit. Founders may hear it in fundraising conversations, especially for high-growth businesses. Revenue alone says nothing about margins, retention or cash needs, so the ratio needs strong context.
Examples of price-to-sales ratio
A listed software company has a $90 million market capitalisation and $15 million of annual revenue. Its price-to-sales ratio is 6. A rival trading at 3 may still be more expensive economically if its growth, retention and gross margin are much weaker.
Common misunderstanding
It is not a measure of profitability and is not the same as enterprise-value-to-sales. Market capitalisation covers equity value, while enterprise value also adjusts for debt and cash. Different revenue recognition or low-margin resale revenue can make company comparisons misleading.
When to use it
Use it to compare similar listed businesses with consistent revenue definitions, particularly before profits stabilise. Pair it with growth, gross margin, retention and cash burn. Do not apply a public-market multiple mechanically to a private startup without adjusting for scale, liquidity and risk.
