The 10 KPIs Every Founder Should Track (And the 20 They Should Ignore)
Founders track too many metrics or the wrong ones. The result is dashboards with 30 numbers and no clarity about what actually matters. A seed-stage startup needs 8-12 KPIs. Not 8-12 dashboards, not 8-12 reports, but 8-12 numbers that the CEO can recite from memory and that directly connect to the questions investors will ask and the decisions the company needs to make. This article identifies the 10 that matter most across SaaS and marketplace businesses and explains why the rest are noise until you reach the stage where they become relevant.

The Criteria for a KPI That Matters
A KPI is only useful if it passes three tests:
Actionable. If the number changes, you know what to do. If MRR drops, you investigate churn and acquisition. If "number of Slack messages sent" drops, you do nothing, because it does not connect to a business decision.
Connected to the model. Every KPI should map to an assumption or output in your financial model. If it does not appear in the model, it is either a vanity metric or you have a gap in your model. Understandable to investors. Your KPIs should be communicable in one sentence. If you need a paragraph to explain what a metric means and why it matters, it is not a KPI. It is an internal diagnostic.
The 10 KPIs
1. Monthly Recurring Revenue (MRR) or Monthly GMV
What it measures: the total recurring revenue generated each month (SaaS) or the total transaction value facilitated (marketplace). This is the top-line heartbeat of the business. Every investor conversation starts here.
Why it matters: MRR trend tells you whether the business is growing, flat, or shrinking. Decompose it into new MRR, expansion MRR, churned MRR, and contraction MRR for the full picture.
2. MRR Growth Rate (Month-over-Month)
What it measures: the percentage change in MRR from last month. Early-stage startups are evaluated on growth trajectory more than absolute revenue. A 15% MoM growth rate from $20K MRR is a very different story from 3% MoM from $500K MRR, and both are relevant. Benchmark: pre-Series A, top-quartile SaaS companies grow 15-25% MoM. Post-Series A, 8-15% MoM is strong. Anything below 5% MoM for more than 3 consecutive months at early stage is a warning signal.
3. Burn Rate and Runway
What it measures: how much cash you spend per month (burn) and how many months of cash remain (runway). This is the existential KPI. Everything else is secondary if you are running out of money.
Track net burn (total cash out minus total cash in) rather than gross burn (total cash out) because net burn reflects the revenue you are generating. Runway = current cash / net burn.
4. Customer Acquisition Cost (CAC) by Channel
What it measures: how much it costs to acquire one customer, broken down by marketing channel. Blended CAC hides which channels work and which destroy value. Investors at Series A will ask for channel-level data. Model implication: CAC by channel feeds directly into your marketing budget allocation and your revenue projections (more efficient channels should get more spend).
5. LTV:CAC Ratio
What it measures: the relationship between the lifetime value of a customer and the cost to acquire them. The standard benchmark is 3:1 minimum for a healthy business. Below 3:1, you are likely losing money on each customer when fully loaded. Above 10:1, you may be underinvesting in growth.
Calculate this by segment and channel, not just as a blended number. Your enterprise segment might be 8:1 while your SMB segment is 1.5:1. Those require completely different strategies.
6. Net Revenue Retention (NRR)
What it measures: how much revenue from your existing customer base grows or shrinks over time, independent of new customer acquisition. NRR above 100% means your existing customers are becoming more valuable. Below 100% means you are on a treadmill.
This is the single most valued metric at Series A and beyond. Bessemer and OpenView both rank it as the number one predictor of long-term enterprise value for SaaS businesses.
7. Monthly Churn Rate (Logo and Revenue)
What it measures: the rate at which customers and revenue are leaving. Track both logo churn (percentage of customers lost) and revenue churn (percentage of MRR lost), because they tell different stories. High logo churn with low revenue churn means you are losing small accounts. Low logo churn with high revenue churn means your big customers are downgrading.
8. Gross Margin
What it measures: the percentage of revenue remaining after cost of goods sold. This determines how much of every dollar you can invest in growth, operations, and profitability. SaaS companies should target 70-85%. Marketplaces on net revenue should target 50-75%.
Gross margin trend matters as much as the absolute number. Improving margins at scale is a strong signal. Declining margins suggests structural delivery cost problems.
9. Cash Conversion Cycle
What it measures: how many days it takes for cash spent to convert back into cash received. This combines days sales outstanding (how long customers take to pay), days payable outstanding (how long you take to pay vendors), and inventory days (if applicable).
For SaaS companies with upfront annual billing, the cash conversion cycle can be negative (you receive cash before you deliver the service), which is a significant advantage. For companies with net-60 enterprise payment terms, the cycle can be 60-90 days, which means you need 2-3 months of working capital that is invisible in a P&L-only view. 10. Payback Period
What it measures: how many months until a new customer has paid back their acquisition cost. CAC / (monthly revenue per customer x gross margin). Best-in-class SaaS companies target under 12 months. Most early-stage startups run 18-24 months.
Payback period is the bridge between unit economics and cash flow. A 24-month payback means you need 24 months of cash to fund each new customer's acquisition before they become profitable. If you are growing fast, that cash requirement compounds quickly.
The Metrics You Should Ignore (For Now)
Total registered users | Vanity. Active users is what matters.
Page views / sessions | Vanity unless conversion rate is attached.
Social media followers | Zero correlation with revenue. NPS score alone | Useful directionally, but not a financial KPI.
Employee satisfaction score | Important for culture, not for the investor model.
Number of features shipped | Output metric, not outcome metric. Total addressable market (as a KPI) TAM is context, not a performance indicator.
Media mentions | PR is not a KPI.
App downloads | Without activation/retention, meaningless.
Revenue per employee | Relevant post-Series B, noise before that.
Frequently Asked Questions
Should my KPIs change as I grow?
Yes. Pre-seed and seed: focus on acquisition metrics and unit economics validation (CAC, early churn signals, MRR growth). Series A: add NRR, segment-level metrics, and efficiency ratios (magic number, burn multiple). Series B+: add revenue per employee, rule of 40 (growth rate + profit margin), and market share metrics. Add complexity as you have the data to support it.
How often should I review KPIs?
The CEO should see the top 5 KPIs weekly. The full set should be reviewed monthly. Board reporting should include all 10 with trend data quarterly. The frequency ensures you catch deviations early enough to act.
Summary
Track 10 KPIs that cover the entire value chain of your business: MRR, MRR growth, burn and runway, CAC by channel, LTV:CAC, NRR, churn (logo and revenue), gross margin, cash conversion cycle, and payback period. Each connects directly to your financial model and to the questions investors will ask. Ignore vanity metrics that do not drive decisions. Review weekly and monthly. Report quarterly to the board. The discipline of a focused KPI set produces better decisions, faster fundraises, and a founder who can defend every number in the model because they live with the data every week.
