The numbers behind **Firefly III net worth** don’t appear in any public ledger. Unlike traditional fintech startups chasing unicorn valuations, this self-hosted accounting system operates in the shadows of Europe’s financial infrastructure—where its true worth lies in what it *doesn’t* cost.

What if the most valuable financial tool you’d ever own wasn’t sold to you, but *given*—then endlessly improved by a global community?
