Terms in this story
- Funding stage: Startups raise money in steps called funding stages: pre-seed, seed, Series A, B, C and later, ending in a stock-market listing or a sale. Each step is larger than the last and asks for more proof.
- Seed round: Pre-seed and seed are the first money a startup raises from outside investors. The difference is mostly how much has been built when the cheque arrives: pre-seed backs an idea, seed backs an early product.
