**APIs profiled:** 0

PrimaryBid was a UK-based fintech that gave retail investors access to public capital markets — IPOs, follow-on equity raises, and public offerings that were historically restricted to institutional investors. It partnered with exchanges, banks, and issuers to broadcast live capital-raising events to individual investors, powering retail participation in listings such as Deliveroo, PensionBee, and Soho House. PrimaryBid's technology was acquired by SoFi Technologies, Inc. in May 2026; the standalone consumer platform has been wound down and its public website now redirects former shareholders to third-party share registrars. This profile is retained in the API Evangelist network as a historical company record. No public developer portal, API documentation, or machine-readable API surface was found during enrichment.
