The 822 SaaS Companies Ranked by Spend from San Francisco (2026)

San Francisco is home to 822 recorded SaaS and AI products headquartered here, led by OpenAI/ChatGPT (4.77% of recorded software spend). The order uses recorded software spend share in the Cledara dataset; directory inclusion does not establish current paid usage. Data as of 26 October 2026, 22:42 UTC.

What this ranking measures

Location is the recorded headquarters, which may differ from where a company was founded or where its customers operate. Vendors are ordered by trailing-12-month software spend share in the Cledara dataset. Recorded products without a current paid observation remain in the directory; inclusion alone does not establish current paid usage.

Annual rank changes use the separate global popularity rank, based on payment activity. Missing calendar endpoints stay unavailable. Founding year, employee and funding fields are recorded enrichment facts, which can be incomplete or historical. Full source data is available from the CSV and JSON download links.

The headline and leader facts describe the complete published location. Search and category selections apply to the directory and its downloads.
