Before an investor reads your narrative, they usually look for three numbers: burn multiple, net revenue retention and gross margin. Together they show how efficiently you grow, whether customers stay and expand, and how much of each unit of revenue you keep. From Series A onward, our view is that these work less as talking points and more as threshold conditions. If they are missing, unclear or inconsistent, the first meeting often does not happen.
Why these three metrics gate the first meeting
Investors screen far more companies than they meet. They need a fast way to judge whether a business has a repeatable, economically sound growth engine. Each of these three metrics answers a separate question, and none can easily stand in for another.
- Burn multiple asks what it costs to grow.
- Net revenue retention asks whether growth compounds from the existing base.
- Gross margin asks whether the revenue is worth having at scale.
A company can show rapid growth that is expensive, a loyal customer base that does not expand, or strong retention on revenue that carries heavy delivery costs. Read together, the three metrics show which of these is happening.
Burn multiple: what growth costs
Burn multiple is net burn divided by net new annual recurring revenue (ARR) over the same period. Net burn is the cash the business consumes from operations, excluding financing. Net new ARR is new business plus expansion, less churn and contraction.
The metric tells an investor how much cash you spend to add each unit of recurring revenue. Lower is better. A falling multiple suggests your go to market motion is maturing. A rising one suggests growth is being bought rather than earned.
Present it quarterly and on a trailing twelve month basis, because a single quarter can be distorted by a large contract or a hiring push. If a one off cost inflated burn in a period, show the figure with and without it and explain the difference. Do not quietly remove it.
Net revenue retention: whether customers grow with you
Net revenue retention (NRR) measures revenue today from customers who were already customers a year ago, divided by what those same customers paid at the start of the period. It includes expansion, downgrades and churn. It excludes new customers entirely.
Strong NRR means the installed base grows on its own, so every new customer becomes more valuable over time. Weak NRR means the company must keep replacing lost revenue before it can grow at all, which feeds directly back into a worse burn multiple.
Investors will usually ask for gross revenue retention alongside it. Gross retention ignores expansion and shows how much revenue you keep. A company with high expansion but heavy churn looks very different from one with modest expansion and almost no churn, even if their NRR is similar.
Gross margin: the quality of the revenue
Gross margin is revenue less cost of revenue, expressed as a share of revenue. For a software company, cost of revenue normally includes hosting, third party software used to deliver the product, customer support, onboarding and implementation staff, and payment processing.
This metric has become more contested as AI products have attracted most of the capital. AI focused companies captured more than 70% of global venture capital in Q2 2026. For many of these businesses, model and inference costs sit inside cost of revenue and can move sharply with usage. Investors now probe margin structure in detail: what drives cost per customer, how it changes with scale, and how much control you have over it.
If you sell services alongside software, show the two margins separately. A blended figure that hides low margin implementation work behind high margin subscriptions will be unpicked in diligence.
Why they become thresholds from Series A onward
At pre seed and seed, investors are largely backing a team and early signal. There is rarely enough history to calculate these metrics reliably, and most investors accept that. By Series A, the company should have enough customers and enough time in market for the numbers to mean something.
Pricing also raises the bar. The median post money valuation on US Series A rounds is about $78.7 million. That median rose 37% year over year. A higher entry price means investors need stronger evidence that growth will compound efficiently, because there is less room for error in their returns.
Capital is also concentrated. Excluding the 16 largest rounds, Q2 2026 resembled a market of roughly $96 billion. For the large majority of companies outside the headline deals, the market is selective, and efficiency metrics are the first filter. If you are assessing whether you are ready, our guide on Series A readiness covers the wider picture.
The same logic applies to debt. Venture debt is commonly used for growth without dilution by companies with efficient ARR of $5 million or more. Lenders read burn and gross margin as closely as equity investors, because both shape the ability to service the facility.
An investor will forgive a weak number they can understand far sooner than a strong number they cannot reproduce.
How to present them honestly
Honest presentation is not only an ethical point. It is practical. Every figure in your deck will be tested against your accounts and customer data in diligence, and any gap costs credibility at the moment it matters most.
- Publish your definitions. Include a short page stating exactly how you calculate each metric, what counts as ARR, and which costs sit in cost of revenue.
- Reconcile to the accounts. Burn should tie to the cash flow statement and gross margin to the management accounts. If they do not, explain why.
- Show the trend. Give at least several quarters of history, so investors can see direction rather than a single flattering point.
- Use cohorts for retention. A cohort view shows whether retention is improving with newer customers or relying on a few early accounts.
- Explain anomalies. If one large customer drives expansion, say so and show the figure without them.
- Keep the data room consistent. The metrics in the deck, the model and the data room should match. Our data room checklist sets out what investors expect to find.
Where a metric is weak, address it directly. State the cause, what you have changed, and the early evidence that it is working. An investor who sees a clear diagnosis is more likely to engage than one who finds the problem on their own.
Mistakes that cost the meeting
The same errors appear repeatedly, and most are avoidable with discipline rather than better performance.
- Annualising the best month. Presenting a peak month multiplied up as ARR invites immediate scepticism.
- Counting signed but not live contracts. Contracted revenue that has not started billing belongs in a separate line, clearly labelled.
- Leaving support and onboarding out of cost of revenue. This inflates gross margin and is one of the first things a diligence team checks.
- Calculating retention on a subset. Excluding small customers or churned segments without disclosure undermines every other figure.
- Changing definitions between rounds. Investors who saw a previous deck will notice, and existing investors will be asked about it.
None of these require a company to have perfect numbers. They require consistency, clear definitions and a willingness to show the full picture.
How Malahide Partners helps
We work with founders and boards to prepare the metrics pack before any investor sees it: agreeing definitions, reconciling figures to the accounts, building cohort views and framing weaker numbers with a clear explanation. We then help position the company with investors whose criteria match its profile, whether for an equity raise or a debt facility. If you are preparing for a raise between $1M and $100M and want a second view on how your metrics will read, book a call.
Frequently asked questions
What is a burn multiple?
Burn multiple is net burn divided by net new ARR over the same period. It shows how much cash a company spends to add each unit of recurring revenue, and a lower multiple indicates more efficient growth.
How is net revenue retention calculated?
Net revenue retention divides current revenue from customers who existed at the start of the period by what those same customers paid at the start. It includes expansion, downgrades and churn, and excludes revenue from new customers.
What should be included in gross margin for a software company?
Cost of revenue should include hosting, third party software used in delivery, customer support, onboarding staff and payment processing. For AI products, model and inference costs usually belong there too.
Why do investors treat these metrics as thresholds from Series A?
By Series A there is enough customer history for the metrics to be reliable, and higher entry prices require evidence of efficient, compounding growth. Companies that cannot show them clearly often do not reach a first meeting.
