How these rosters are built
A round is listed once its amount, round and lead investors are confirmed at the company's own announcement or at the outlet that reported it, and both are linked on the entry. Nobody pays to be listed. Every week is also in /weeks.json, and each week's page has a Markdown twin. Full method.
