The only metrics that matter at $0

The MRR stage answers one question: can it make money? Not "did people star it" or "did the launch get upvotes." The jump from LAUNCH to MRR is the first time your product faces commercial reality — and the metrics that matter are fewer than you think.

Signups, activation, first payment

Everything reduces to a three-step funnel:

1. Signups — people arrived. (Distribution works. Barely interesting.)
2. Activation — they did the thing the product is for. (This is where most products quietly die.)
3. First payment — someone exchanged money for value. (The only unfakeable signal in software.)

Watch the conversion between the steps, not the totals. 500 signups and zero activations is a product problem dressed as a marketing problem. Fix the leak with the fewest people through it before pouring more in.

Your dashboard is lying to you (vanity vs signal)

Totals always go up; rates tell the truth. Cumulative signups, downloads, pageviews, followers — every one of them can rise while the product dies. The honest metrics are rates and cohorts: activation rate this week, week-2 retention of last month's signup cohort, revenue per new user. If a metric can't go down when things get worse, it's decoration.

Churn math for people who hate math

Monthly churn of 10% means the average customer stays ten months — fine. It also means you must replace a tenth of your base every month just to stand still. At 20%, you're on a treadmill that speeds up. You don't need a finance degree: divide cancellations by the base, look at it monthly, and treat a bad trend like a stage-gate blockage — named, investigated, fixed.

Where the OS enforces this

• Live Data Feeds pull MRR, customers, and churn in from Stripe-shaped webhooks — the numbers you argue with are the real ones, delivered on their own.
• Reports turn the numbers into per-product economics: MRR, ARPU, costs, and a founder-adjusted net.
• The MRR gate requires actual, feed-verified revenue — hand-entered optimism doesn't advance stages.

Reports — the portfolio's numbers, including the founder-adjusted net that subtracts your own hours.
