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.
- Series B/C: Series B, C, D and later rounds are growth rounds: large cheques that help a startup with a proven model expand faster, enter new markets or move toward profit and a listing.
- Valuation: A startup's valuation is the price investors agree the whole company is worth. For young companies it is set by negotiation and comparison, not by a formula.
- Accelerator: An accelerator is a short, intense programme that gives a startup a small investment, mentors and a network in exchange for equity. An incubator offers space, mentoring and services over a longer period, often at a university, and may or may not invest.
