Y Combinator companies by category
How this is counted
Companies are the ones Y Combinator lists in its own directory, with the batch it published. A latest raise is the company's newest round beyond the batch itself; its amount links to where it was reported, and totals sum the rounds that link to a source. Founders are the people on record at each company. The same data as JSON: /api/v1/accelerators/yc. All accelerators.
