Why startups really fail

Running out of cash is where the story ends. Not why.

70% of failed startups ran out of capital — but that's the final symptom. The real causes are why the capital dried up in the first place.

The Brain

A brain for your startup, not just a dashboard.

Other tools are speedometers, which show how fast you're burning. Startup Brain is the navigation. It reads your metrics, names the cause that's draining your runway, and hands you ranked moves with the runway each one buys.

Diagnoses

Unsustainable unit economics

Reads CAC, LTV, margins and channel profitability, and tells you exactly what's underwater.

Our primary, strongest claim, read directly from your numbers.

Flags

Product-market fit risk

Spots when retention and churn signals look like a market-need problem, and points you where to dig.

A signal to investigate, not a claim to diagnose PMF from cash data.

Won't fake

Market timing

We don't pretend to call the macro. We keep the things you control from being what kills you.

Honest scope is a feature. We won't sell you a crystal ball.
