Research & Case Studies

The financial decisions behind survival and failure.

We study why startups make it — and why they don't. Practical research and case studies for founders who'd rather learn from someone else's burn than their own.

The Burn Report 2026

$15B+
raised across four startups — and lost

Builder.ai, Northvolt, 23andMe, and Lilium raised more than $15 billion between them and still failed. We break down what went wrong financially — and the warning signs founders can spot before they become fatal.

  • Builder.ai — when financial reporting breaks down
  • Northvolt — growth without operational readiness
  • 23andMe — the revenue model problem
  • Lilium — the cost of long timelines
