The Six Numbers Behind a B2B Raise

A founder walks into the room with a story: the vision, the demo, the logos, the size of the market. A numerate investor listens, and quietly reduces all of it to about six numbers. Not because the story doesn't matter, but because these six are the ones that reveal whether the story is actually a business.

What an investor reads first

The reason these numbers matter so much is that they are hard to fake and hard to argue with. A founder can frame a market, spin a competitor, and reframe a setback, but growth rate is growth rate and gross margin is gross margin. Together they answer the question underneath every B2B raise: is this a company that turns each dollar of investment into more than a dollar of durable, efficient growth? The pitch is the wrapping. These six are the contents.

The benchmarks below are drawn from Bessemer's cloud research and the now-standard efficiency metrics that came out of the last decade of SaaS investing. Treat them as the line a good company clears, not exact targets, and remember that the bar moves with stage: an early seed company is judged on the trajectory of these numbers, a growth-stage company on their level.

Demand, durability, efficiency

The six split cleanly into three things an investor is testing. The first pair, growth rate and net revenue retention, measure demand: not just whether new customers are arriving, but whether the ones already inside the account are leaning in and spending more. High growth with weak retention is a leaky bucket that fundraising temporarily hides. Strong net revenue retention is the rarer and more telling of the two, because it means the product earns its expansion without the company paying to win the customer twice.

The second pair, gross margin and CAC payback, measure durability. Gross margin decides how much of every sale is actually yours to reinvest, and a B2B company carrying heavy delivery or support costs is quietly a services business wearing a software valuation. CAC payback decides how long your cash is tied up before a customer becomes a net contributor. This is where pricing shows up in the numbers: a price set too low, the trap covered in our piece on enterprise pricing, damages margin and stretches payback at the same time, weakening two of the six at once.

The last pair, burn multiple and the Rule of 40, measure efficiency, and they have moved to the centre of the table in the last few years. After a long stretch where the market rewarded growth at almost any cost, investors now ask how much cash a company consumes to produce that growth. Burn multiple, popularised by David Sacks, captures it in a single ratio of net burn to net new revenue. The Rule of 40 sets a combined floor for growth and profitability together, so a company can be forgiven low margins if it is growing fast, or modest growth if it is genuinely profitable, but not weakness on both.

Why founders misread their own numbers

The common mistake is to lead with the one number that looks best and stay quiet on the rest. A founder with spectacular growth and an ugly burn multiple will spend the whole meeting on growth, but a numerate investor reads silence on a metric as a problem being hidden, exactly as they do with the third lens in what disciplined VCs evaluate. The stronger move is the opposite: name your weakest number before they find it, and show the path that fixes it. A known weakness with a plan beats a strength that turns out to be carrying a buried one.

The numbers also interact, which founders rarely present. Channel access, the theme running through this whole series, improves several at once: a warm path to the buyer lowers customer acquisition cost, which shortens CAC payback and improves the burn multiple, while a well-served enterprise account expands over time and lifts net revenue retention. One operating advantage can move three of the six. That is why how a company reaches its market is not separate from its metrics. It is upstream of them.

The takeaway

A pitch is judged on its story; a company is judged on its six numbers. Demand, durability, efficiency: growth and net revenue retention, gross margin and CAC payback, burn multiple and the Rule of 40. The founders who raise well know their own scorecard better than the investor across the table, lead with the truth rather than the highlight, and can explain not just where each number sits but what moves it. The deepest version of that answer is usually not a new tactic inside the funnel. It is a better way into the market, which improves several of the six at the same time.

It is the same scorecard EvoScale Capital reads on every B2B submission, paired with operators who have actually moved these numbers from the inside rather than only modelled them. In a market where capital is plentiful, the teams that compound are the ones who treat their metrics as a system to engineer, not a report card to defend.
