Silicon Valley and San Francisco
San Francisco, the Peninsula and the South Bay are separate cities that share a labour market. Software, semiconductors and laboratories are not one building type.
Last reviewed 27 October 2026
- SectorsNoteThe kinds of firms that occupy space here. Software and a laboratory need different buildings.
- TalentNoteWhere people are hired from, and what the employment contract allows.
- UniversitiesNoteThe campuses that feed the labour market. A university and a startup are different organisations.
- Venture capitalNotePrivate funds share one federal rulebook. A national total, when this note prints one, is dated. Cities are left unranked.
- Company formationNoteWhere the legal person is created, and how that differs from a tax-identification application and from the city where the staff sit.
- ExitsNoteA public listing or a sale of the company. The federal pathways are shared. Whether the local office and the local jobs remain is a separate fact.
- EmploymentNotePayroll, kept apart from a funding announcement. Large employers and new firms are counted separately.
- Housing and commercial spaceNoteHow the jobs reach a bedroom and, only sometimes, a lease.
Delaware filings, the SEC private-fund rules and the H-1B cap stay on the ecosystems page, not on each topic.
The same place in real estate. Statewide tax and rent rules are on the California real estate note.
