Businesses have historically been valued based on their ability to generate cash. A company earns revenue, pays its operating expenses, reinvests in the business, and distributes the remaining cash to its owners. The greater and more reliable those future cash flows are, the more valuable the business should be today.
Yet software companies appear to break this rule. For much of the past decade, public investors, private equity firms, and strategic acquirers discussed software valuations almost entirely in terms of revenue. A company could be valued at 5, 10, or even 20 times recurring revenue despite producing little EBITDA and, in many cases, burning cash.
But software was never truly valued on revenue. Revenue became the preferred proxy for future cash flow when current profitability didn’t accurately reflect the economics of a growing subscription business.
That distinction is particularly important after the significant software repricing event of early 2026. Public SaaS multiples have roughly halved since 2024, and across the software market investors are recalibrating around EBITDA and profitability after years of pricing growth first. Below, we dive into why revenue was used as a proxy for intrinsic valuation in software. In future posts in this series on software valuation, we’ll explore how that calculation is fundamentally changing.
Revenue multiples were a shortcut
The fundamental value of any company remains the present value of the cash it can generate over its lifetime. A revenue multiple simply compresses a large number of assumptions about growth, retention, margins, reinvestment, and risk into one number.
When an investor pays eight times revenue for a software company, that investor is implicitly assuming that the company will:
- Retain most of its customers
- Grow revenue for several years
- Maintain attractive gross margins
- Develop meaningful operating leverage
- Reduce customer acquisition costs as a percentage of revenue
- Eventually produce substantial free cash flow
The revenue itself doesn’t create value. The expected cash flow attached to that revenue does.
Today, every item on that list is being questioned at once. Rates raised the cost of waiting for cash that shows up in year seven. AI raises the harder question of whether it shows up at all, if seats compress or a competitor rebuilds the product for a fraction of what it cost the first time.
Why current profit could understate a software
business
A growing software company can choose between maximizing cash flow today and spending to acquire customers, build products, and expand distribution. The costs of that investment are incurred now, while the subscription revenue may arrive over several years.
That timing mismatch can make two economically different decisions look similar in a current income statement. A company with low EBITDA may have a weak business model. Or it may be reinvesting aggressively because every dollar spent today creates a valuable stream of recurring gross profit.
This is why investors were willing to tolerate low current margins when customer acquisition was efficient, retention was strong, and the mature margin opportunity was credible. Current losses could be described as investment. High sales and marketing costs could be justified by lifetime customer value. Product development could create benefits that accounting did not fully recognize as an asset.
Valuation therefore depended less on what the company earned today and more on what it could earn after moderating its growth investment.
That trade only works when investors expect a business will mature into an attractive margin profile. In 2026, investors want proof of that maturity today, not a promise it will come later. The reinvestment story that earned a premium in 2021 gets read as a risk today. The founders that feel that most sharply are running good businesses with low or no EBITDA and a profitability plan the market no longer takes at face value.
Why revenue was especially useful for SaaS
Revenue is a weak valuation proxy for most industries. Yet it worked well for subscription software, especially when great software products were differentiated, difficult to build, and hard to replicate. Here’s why:
1. Recurring revenue created visibility
A subscription software company begins each period with an installed base of customers. When gross retention is strong, current annual recurring revenue provides a useful starting point for estimating next year’s revenue, future gross profit, and the amount of new selling required merely to replace churn.
2. High gross margins created operating leverage
Once software has been developed and deployed, serving another customer may require relatively little incremental cost compared with producing another physical product. That creates the potential for high gross margins and meaningful operating leverage as the business scales.
3. Revenue remained comparable when earnings were negative
Earnings multiples are difficult to use when EBITDA is negative or heavily affected by discretionary growth spending. Revenue gave investors a common denominator for comparing businesses at different stages of maturity and with different reinvestment strategies.
This reason has partly expired. Sector EBITDA margins kept widening as growth slowed, so many software companies now have earnings you can compare. Investors are benchmarking them.
4. The model was relatively capital-light
Many software companies required limited capital and modest working-capital investment. If revenue remained durable and margins expanded, a large portion of mature operating profit could convert into free cash flow.
Together those four traits made a dollar of recurring revenue a decent stand-in for the cash a mature software business would eventually produce. In holding these traits as true and valuing businesses on revenue multiples, investors inherently were making several assumptions about the future of software as a business model. Many of those assumptions are being tested today. A revenue multiple hid a more complex view of several underlying variables.
What was hidden inside the multiple
The phrase “valued at eight times revenue” made the valuation process appear simpler than it was. In reality, the multiple represented a view on several underlying variables:
- Growth: How quickly can the company expand, and for how long?
- Retention: How much existing revenue survives before new selling begins?
- Gross margin: How much of each revenue dollar becomes gross profit?
- Operating leverage: What margin can the company reach at scale?
- Reinvestment: How much spending is required to sustain growth?
- Risk: How certain are the revenue, margin and competitive assumptions?
- Duration: How long can the company earn attractive returns before competition or disruption erodes them?
Two companies with the same revenue could therefore deserve very different multiples. A company with 95% gross dollar retention, 85% gross margins, and efficient customer acquisition has a much clearer path to future cash flow than a company with 80% retention, significant services work, and persistent acquisition losses.
When the revenue proxy breaks
Revenue multiples become dangerous when investors treat all recurring revenue as economically equivalent. The proxy weakens when a company has poor retention, weak gross margins, high implementation costs, short contracts, excessive customer concentration, or no credible path to mature profitability.
It also weakens when the future becomes harder to forecast. The more uncertainty investors face around pricing, competition, customer behavior, or technological disruption, the less willing they are to capitalize distant cash flows on faith.
That is the central change in the current software market. Investors have not abandoned the idea that growth creates value. They are demanding more evidence that the growth is durable and that recurring revenue will actually become cash. Revenue was never the destination. It was a proxy for the durable cash flow investors believed would eventually emerge.
