Most solo founders I talk to are drowning in dashboards but starving for insight. They're tracking vanity metrics while the numbers that actually predict survival go unmonitored.

Here are the 3 I see misused constantly:

1. MRR instead of Net Revenue Retention

MRR tells you how much you're billing. NRR tells you if your existing customers are getting MORE valuable over time. If your NRR is below 100%, you're filling a leaky bucket. Track expansion revenue, not just new logos.

2. Total signups instead of Activation Rate

Signups are ego fuel. What matters is how many people hit their "aha moment" — the action that correlates with long-term retention. For most SaaS, this is completing a core workflow within the first 48 hours. If you're not measuring this, you're flying blind.

3. Page views instead of Time-to-Value

Traffic is noise. The real question: how fast does a new user go from landing on your product to getting actual value? Shorten that window and everything else improves — retention, word of mouth, LTV.

This is exactly why we built Avantisapp — to make these metrics visible without needing a data team. Connect your warehouse, set up a dashboard in 5 minutes, and actually see what's happening in your business.
