- Where the figures come from.
- Each valuation is a record: what Snorkel AI or its investors announced, or what a named outlet reported, with the page it was read on. A valuation a company was only in talks to raise at is not its valuation here, and an estimate site's figure is never a record.
- Valuation and revenue.
- A valuation is what investors paid per share times all the shares, often with terms that favour the newest investors; set against revenue it shows what the market pays for each dollar of it, not what the company would sell for.
