The 7 Metrics Every Startup Founder Should Track Weekly

There are probably forty metrics you could track. Most of them don't matter yet.

At the seed stage, your job is to prove that people want what you're building and that the economics aren't going to kill you before you get there. That's it. You don't need a 12-tab analytics dashboard. You need seven numbers, checked every Monday morning.

These are the seven. I'm going to tell you how to calculate each one, what a reasonable number looks like at seed stage, and why you should care.

1. Monthly Recurring Revenue (MRR)

MRR is the number. If you only track one metric, this is the one. Every investor will ask for it. Every board deck starts with it. Your MRR tells you whether the thing you're building is generating predictable income or just one-off payments that could disappear next month.

Formula: Sum of all active recurring subscription revenue in the month
Example: 142 customers × $49/mo avg = $6,958 MRR

At seed stage, $5K–$15K MRR with month-over-month growth of 15%+ is strong. The absolute number matters less than the slope. Flat MRR at $10K is worse than $3K MRR growing 20% per month.

2. Net Burn Rate

Burn rate is how fast your bank account is shrinking. Gross burn is your total monthly spend. Net burn subtracts whatever revenue you're bringing in. Net burn is the one that matters because it tells you the actual speed at which you're approaching zero.

We wrote a full breakdown on this in our founder's guide to burn rate.

Formula: Total monthly expenses − total monthly revenue
Example: $38K expenses − $7K revenue = $31K net burn

For a seed-stage company with 2–5 people, $25K–$50K net burn is typical. If you're burning more than that before product-market fit, something is off.

3. Runway

Runway is how many months you have before you run out of money. It's the single most important number for survival. And most founders calculate it wrong because they use last month's burn rate as if it'll stay constant. It won't. You'll hire, you'll spend more on ads, your cloud bill will creep up.

We covered the common mistakes in our startup runway calculator guide.

Formula: Cash in bank ÷ net monthly burn rate
Example: $480K cash ÷ $31K burn = 15.5 months runway

Eighteen months is comfortable. Twelve is fine if you're growing fast. Below nine months, you should already be fundraising or cutting costs. Below six, you are in trouble.

4. Customer Acquisition Cost (CAC)

CAC tells you what it costs to get one paying customer. This includes everything: ad spend, sales salaries, tools, the free trial infrastructure, all of it. If you don't know your CAC, you don't know whether your growth is profitable or just expensive.

Formula: Total sales + marketing spend ÷ number of new customers acquired
Example: $4,200 spend ÷ 28 new customers = $150 CAC

The benchmark that gets thrown around is a 3:1 LTV-to-CAC ratio. At seed stage, your CAC will be ugly. That's expected. What you want to see is the number trending down each month as you learn which channels actually work. A seed-stage B2B SaaS typically sees CAC between $100–$500.

5. Churn Rate

Churn is the percentage of customers who cancel in a given period. High churn means you have a leaky bucket. You can pour as many new customers in as you want, but if they're leaving out the bottom, your MRR will never compound.

And churn is sneaky. A 5% monthly churn rate sounds small until you realize that means you're losing nearly half your customer base every year.

Formula: Customers lost during period ÷ customers at start of period × 100
Example: 8 churned ÷ 142 starting = 5.6% monthly churn

For B2B SaaS at seed stage, under 5% monthly churn is acceptable. Under 3% is good. If you're seeing 8%+, stop acquiring customers and figure out why people are leaving. Pouring water into a broken glass is a waste of money.

6. Activation Rate

This one gets overlooked constantly. Activation rate measures how many people who sign up actually do the thing that makes your product useful. For a project management tool, maybe that's creating a project and inviting a teammate. For an analytics tool, it's connecting a data source.

If your activation rate is low, nothing else will work. You can't retain users who never got started.

Formula: Users who completed key activation action ÷ total signups × 100
Example: 67 activated ÷ 210 signups = 31.9% activation rate

A 25%+ activation rate is decent for self-serve SaaS at seed stage. Over 40% means your onboarding is working. Below 15% means your signup-to-value path is broken, and you should fix it before you spend another dollar on acquisition.

7. Weekly Active Users (WAU)

DAU gets all the attention, but for most B2B products, weekly is the right cadence. Your users aren't opening your app every day. They probably shouldn't be. But if they're coming back every week, you have something sticky.

WAU is a gut check on engagement. MRR tells you who's paying. WAU tells you who's actually using the product. When those two numbers diverge, you've got a churn problem waiting to happen.

Formula: Count of unique users who performed any meaningful action in the past 7 days
Example: 89 WAU out of 142 paying customers = 62.7% weekly engagement

At seed stage, a WAU-to-paying-customer ratio above 60% is strong. It means most of the people paying you are actually getting value. If it drops below 40%, your product might be getting bought but not used.

The Monday Morning Routine

Put these seven numbers in a single view. Check them every Monday before you do anything else. It takes five minutes. You'll catch problems weeks earlier than you would otherwise, and you'll stop wasting time on metrics that look interesting but don't actually tell you anything about the health of your company.

The founders I know who run disciplined companies all have some version of this habit. The ones who don't are usually surprised when things go sideways.
