SF AI Index
A monitoring system for what is happening in San Francisco AI — news, people, new companies and funding, events, and hiring. A coordinator delegates to specialised subagents; every record it publishes carries the source it came from.
Status
Under construction. The collection pipeline is being built before the interface, because the interesting part is the pipeline — the site is how you read what it produces.
- Record schema with provenance — every value carries its origin, its source and a per-field confidence. An inferred value cannot overwrite a sourced one.
- Structured error contract — transient, validation and permission failures are distinguished, so a rate limit is retried and a refusal never is.
- Question bank — 322 questions for the certification this build is aimed at.
- Collection pipeline — an MCP server over Hacker News, schema-enforced extraction with a validation-retry loop, and per-call cost metering.
- Next: batch processing, then the coordinator and the remaining subagents.
The six subagents
- Briefnews, launches and research — every claim cited
- Roompeople: who moved, who is speaking, who left to found something
- Newconew companies, funding, YC batches
- Calendarevents, with judgement about what is worth attending
- Hiringwhich companies are hiring, and what they screen for
- Wardenreviews this project's own pipeline in CI
