Secondary Flow is a research tool, not a broker-dealer or a marketplace, so it does not execute transactions in Zipline or any other private company. Private-company shares typically change hands through a company-approved tender offer, a direct transfer subject to the company's right of first refusal, or a regulated secondary marketplace, and most transfers require issuer consent. Secondary Flow tracks the resulting prices.
