Valuing a Startup by Working Backward From Its Exit
A startup with little revenue cannot be valued on normal methods. The venture capital method starts from what it might be worth when sold, then works backward to justify an investment today.
The Problem With Valuing Startups
Conventional valuation methods rely on earnings, cash flows, or comparable trading multiples. A young startup has none of these in usable form: it may have little revenue, no profit, negative cash flow, and no stable business to compare. The standard tools produce nonsense or nothing.
The venture capital method is a way to value such companies despite this. Rather than valuing the company on what it is now, it values it on what it might become, starting from an estimated future exit value and working backward to determine what an investment today should be worth.
You cannot value a startup on what it earns, because it earns nothing. You value it on what someone might pay for it years from now, then work backward to today.
Working Backward From the Exit
The method runs in reverse compared to normal valuation. It begins at the end, the exit, and works back to the present.
| Step | What it does |
|---|---|
| Estimate exit value | What the company might sell for at exit |
| Apply required return | Discount back at a high target return |
| Account for dilution | Adjust for future funding rounds |
| Derive todays value | What the company is worth now |
The investor estimates what the company could be worth when it is eventually sold or goes public, perhaps by applying a multiple to its projected revenue or earnings at that future point. Then, because that exit is years away and highly uncertain, the value is discounted back to the present at a very high required rate of return, reflecting the enormous risk that the startup fails entirely.
The High Required Return
The discount rate used is far higher than for a normal company, often demanding that a successful investment return many times the money invested. This seems extreme until the failure rate is considered.
Venture investing is characterised by most startups failing and a few succeeding enormously. The investor knows that many investments will return nothing, so the ones that succeed must return a great deal to make the overall portfolio work. The high required return on any single investment is not a prediction that it will return that much, but a reflection of the need for the winners to compensate for the many losers. This connects to how venture portfolios are built around the expectation that most investments fail and a few must pay for all of them.
The Dilution Adjustment
A crucial refinement is accounting for future funding rounds. A startup will typically raise more money before it exits, and each round issues new shares that dilute existing investors, reducing their percentage ownership.
An investor buying a stake today will own a smaller percentage of the company by the time it exits, because of the shares issued in between. The method must account for this dilution, since the investor eventual share of the exit value is smaller than their share today. Ignoring dilution overstates what the investment will be worth, so the method adjusts for the expected future rounds to estimate the investor actual eventual ownership and therefore the value of investing now.
The Honesty About Uncertainty
The venture capital method is transparent about resting on highly uncertain estimates. The exit value is a guess about a company years in the future, the required return reflects extreme risk, and the whole exercise acknowledges that most such investments will not work out.
This honesty is a feature, not a flaw. The method does not pretend to precision it cannot have; it provides a framework for thinking about what a risky, early stage investment could be worth, given assumptions that are openly uncertain. It is a tool for structuring a decision under enormous uncertainty rather than for producing a confident valuation, which suits the reality of investing in companies whose future is genuinely unknowable.
The Bottom Line
The venture capital method values a startup that cannot be valued conventionally by starting from an estimated future exit value and working backward, discounting at a very high required return that reflects the high failure rate of startups. It adjusts for the dilution from future funding rounds, since an investor eventual ownership will be smaller than their stake today. The method rests openly on uncertain estimates, which is appropriate for early stage investing, providing a framework for deciding what to pay now for a company whose value lies entirely in an uncertain future.
