Many founders have an idea with a lot of potential, a validated product, and even monthly recurring income, but they fail to present that information in a structured, understandable and convincing way to investors.
In this article, we delve into the metrics that really matter, starting with the basic ones such as MRR and ARR, and moving on to more sophisticated metrics such as CAC Payback, Burn Multiple or Net Revenue Retention (NRR). The goal is to understand how to transform data into a financially attractive narrative for investors.
The real importance of financial metrics for investors
Investors don't make decisions based on intuition or promises. What they are looking for are startups with a validated, scalable and efficient business model. The metrics allow us to understand where the business is at, what is its capacity to generate recurring revenues, what its financial health is and how effective its growth strategy is.
For venture capital funds, these numbers serve as the “common language” for comparing investment opportunities. A pitch can be brilliant, but without clear KPIs, any story loses credibility. Financial metrics, therefore, are much more than indicators: they are quantitative arguments that support the investment thesis.
Understanding MRR and ARR from an advanced perspective
The MRR (Monthly Recurring Revenue) and the ARR (Annual Recurring Revenue) are the basic metrics that any SaaS startup should report. However, for these figures to really say anything, it is necessary to go beyond their superficial calculation. The MRR isn't just a picture of monthly recurring revenue, but a window into business behavior.
When we break down the MRR in components such as New MRR (new customers), Expansion MRR (upgrades), Reactivation MRR (reactivated customers) and Churned MRR (losses), we are beginning to see what is driving or weakening growth. For example, if most of the monthly growth comes from Expansion MRR, that's a sign that the product is delivering real value and that customers are willing to pay more. Conversely, if the New MRR is high but so is the Churned MRR, there may be a retention problem that calls into question the sustainability of the model.
El ARR, on the other hand, should not be used only as an extrapolation (MRR x 12). It is essential to clarify what part of that ARR is actually committed through signed contracts or annual subscriptions, and how much is simply estimated. In addition, it is very useful Separate the ARR by segment, type of customer, or region to show in which verticals traction is consolidating.
Unit Economics: the metrics that reveal efficiency
For any investor, understanding unit economics is as important as knowing the volume of income. These metrics show how much it costs to acquire a customer, how much value that customer provides over their lifespan, and how quickly that investment recovers. The CAC (Customer Acquisition Cost) becomes significant when compared to the LTV (Customer Lifetime Value), and especially when analyze the CAC Payback Period.
The latter indicates how much time you need to recover what you invested in getting a customer. If a SaaS startup takes longer than 12-15 months to recover the CAC, financial risk increases. That's why funds are so fixated on payback: it's a reflection of efficiency and speed of return. If, in addition, the gross margin per customer is low, the problem worsens.
Another highly rated advanced metric is eThe Burn Multiple, which measures how much capital the company burns to generate each new euro of ARR. If the multiple burn is 3x, it means that the startup spends 3 euros to get 1 euro of additional ARR, which may be acceptable in very early stages but unsustainable in the long term. Startups with a multiple burn < 2x tend to attract more interest in rationalized funding contexts.
The Rule of 40 and other financial health indicators
One of the most used rules in the SaaS world, especially in startups in the growth phase, is “Rule of 40". This metric combines growth rate with profitability. It is calculated by adding the annual growth percentage with EBITDA (or operating margin) in percentage. If the sum is equal to or greater than 40%, the business is considered to be in a good position to scale without jeopardizing its sustainability.
This makes it possible to evaluate companies that are not necessarily profitable, but that are growing rapidly with acceptable margins. Or the other way around, startups that have moderated their growth but are already generating positive cash flow. The versatility of this metric makes it particularly attractive for growth or late stage funds.
NRR: the metric that makes investment funds fall in love with
Net Revenue Retention (NRR) has established itself as one of the most powerful metrics to demonstrate the strength of the business model. Unlike the Churn Rate, which only reflects what is lost, the NRR also includes what is earned within the same customer base. If a startup has an NRR greater than 100%, that means that it is growing even without acquiring new customers, which is an unequivocal sign of a valuable and well-adopted product.
For investors, a growth-stage NRR > 110% is a green light that justifies a round. If it is < 90%, it is perceived as a warning sign that requires in-depth investigation.
Cohorts, Segmentation and Financial Storytelling
A common mistake among entrepreneurs is to present KPIs in an aggregated form, without segmenting or contextualizing. Showing cohorts allows demonstrate retention and real customer behavior over time. Analyzing monthly or quarterly cohorts from the time of purchase allows us to see if users remain active, if they increase their average ticket or if they abandon quickly.
Segmentation by channel, region, or customer type also helps identify which strategies work best. For example, the CAC on Google Ads may be higher than on LinkedIn, but if the LTV is 4 times higher, then that channel may be more profitable in the long run. Understanding these cause-effect relationships demonstrates business maturity and control.
The ultimate goal is not just to show numbers, but to build a coherent narrative based on data. Effective financial storytelling integrates growth, efficiency, retention and future profitability. That's the combination that investors are looking for.
Conclusion: metrics as an investment communication strategy
A startup with good indicators but a mediocre presentation may miss an investment opportunity. That's why thoroughly understanding your KPIs and knowing how to report them is a critical skill. Data alone is not enough: it needs context, segmentation, coherence and honesty.
