Are you focusing on the right B2B Startup Metrics to drive growth?
Most founders love to talk about metrics—but are they tracking the ones that truly matter?
Before diving deeper, let’s take a moment to understand what startup metrics actually are.
Startup Metrics: A Quick Overview
Startup metrics are quantifiable indicators that track the performance, growth, and overall health of a startup. These metrics provide founders, teams, and investors with essential insights into how well the business is doing, helping to make informed decisions, optimize strategies, and measure success over time.

Why Are Startup Metrics Important?
It’s simple: you can’t improve what you don’t measure. Picture yourself flying an airplane without instruments—pretty nerve-wracking, right? That’s exactly what it’s like running a startup without metrics. Metrics are the instruments that keep you on course, ensuring that you’re not only growing but growing in the right direction.
Here’s why startup metrics are crucial and what they typically include:
- Informed Decision-Making: Metrics provide real data that help founders make decisions based on actual performance rather than intuition or guesswork.
- Measure Growth: Metrics track the startup’s progress and help determine if it’s moving in the right direction.
- Identify Weaknesses: By measuring specific areas (like customer churn or burn rate), founders can identify potential problems early and make adjustments.
- Investor Confidence: Startups that consistently track and report key metrics are better positioned to attract and retain investor support.
- Benchmarking: Metrics allow startups to compare their performance against industry standards and competitors.

Which B2B Startup Metrics Should You Track?
The biggest mistake many founders make is waiting until after their product launch to track metrics. Imagine launching with a bang, only to realize later that you don’t know who’s returning to your product, how many are churning, or what your daily active user numbers look like.
Key Metrics Selection is all about aligning your metrics with your business objectives. According to Tom Blomfield, Group Partner at Y Combinator, for B2B startups, revenue is often the most telling metric. As he emphasizes, “Revenue should be the key focus because it’s the true reflection of how well your product is performing.” Are you generating income, or just interest? Other crucial metrics Tom highlights include customer acquisition cost (CAC), customer lifetime value (LTV), and churn rate. The goal, as he points out, is to focus on numbers that directly influence your bottom line rather than vanity metrics that don’t reflect real progress.
Tom Blomfield, Group Partner at Y Combinator always recommends tracking pre-launch metrics—even before your product hits the market. This will give you a clear picture of early user engagement, which is critical to making adjustments on the fly.
He identifies several key metrics that B2B startups should prioritize. These metrics help founders make better decisions, avoid common mistakes, and provide clarity when reporting to investors.
Key Startup Metrics To Track
While the specific metrics vary depending on the industry, business model, and growth stage, here are some of the most critical metrics for startups:
- Revenue: The most direct measure of a startup’s success. For SaaS startups, this is often tracked as Monthly Recurring Revenue (MRR) or Annual Recurring Revenue (ARR).
- Customer Acquisition Cost (CAC): The cost of acquiring a new customer, including marketing and sales expenses.
- Lifetime Value (LTV): The total revenue a customer generates over the duration of their relationship with the startup. LTV should ideally exceed CAC.
- Churn Rate: The percentage of customers who stop using the product or service within a given period. Reducing churn is critical for maintaining long-term growth.
- Retention Rate: The percentage of customers who continue to use the product over time. High retention means users find the product valuable.
- Net Dollar Retention (NDR): Measures how much revenue you retain from existing customers after accounting for upgrades, downgrades, and churn. NDR above 100% means your revenue is growing from existing customers.
- Burn Rate: The rate at which the startup is spending its cash. It’s important to monitor burn rate to ensure the startup has enough runway to reach key milestones before needing additional funding.
- Runway: The number of months a startup can continue operating at its current burn rate before running out of cash. It’s a vital metric for financial planning and fundraising.
- Gross Margin: The percentage of revenue that remains after subtracting the cost of goods sold (COGS). Higher gross margins indicate a more profitable business model.
- Engagement Metrics: These include metrics like Daily Active Users (DAU) or Monthly Active Users (MAU), which indicate how frequently users engage with the product.

How To Use Startup Metrics
- Track Progress: Regularly monitor your key metrics to measure growth and assess whether the startup is on track to achieve its goals.
- Iterate and Improve: Use metrics to identify weaknesses or inefficiencies and adjust your strategies accordingly.
- Report to Stakeholders: Keep investors, board members, and team members informed by sharing relevant metrics through reports or updates.
- Make Data-Driven Decisions: Metrics should form the basis for key business decisions, helping you prioritize efforts that will have the greatest impact.
Is Consistency In Metrics Important?
Without a doubt. Consistency in Metrics ensures that you’re comparing apples to apples over time. Changing how you define or measure a metric can lead to confusion and misinformed decisions. Praveen always stresses the importance of having agreed-upon definitions within your team. This way, everyone is on the same page, and you can track progress accurately.
What Should You Include In Investor Updates?
Transparency is key when communicating with investors. Investor Update Metrics should always feature your revenue, burn rate, and runway at the very least. These metrics provide a clear picture of your financial health and operational efficiency. Even if the numbers aren’t where you want them to be, honesty fosters trust and opens the door for valuable advice.
