Search by what an investor has done, not what its website says

Every organization here entered through a public record: a Form ADV filing that claims the venture capital fund adviser exemption or reports venture funds, a Form D venture vehicle, a portfolio page, or a cited announcement. The class chip says what kind of organization it is and how sure we are; the profile says why. Candidates are shown as candidates and are not counted as coverage.
