Questions founders ask
Why does every term link to a tool?
Because the fastest way to understand a term is to see what it does to your numbers. Each tool runs in the browser and stores nothing.
Is the glossary US-specific?
Most terms come from US venture practice, which the rest of the world has adopted. Where the UK or EU uses a different instrument, the entry says so.
Can I suggest a term?
Yes. Email the term and where you saw it; we add the ones founders ask about most.
