Investors are named from the companies' own announcements, the investors' own pages, Y Combinator's company pages, public filings and news reports of a round, each with its source. An investor isn't a sign of quality, and nobody can pay to be listed or to change a grade. To correct something or have a page removed, write to privacy@anchorterminal.com.
