Source registry
Every source feeding EarlySeed, its evidentiary tier, and its last successful crawl. T0 = legally mandated registry filings; T4 = weak social signal (never sufficient alone to publish a round).
| Source | Type | Tier | Last success | Records |
|---|---|---|---|---|
SEC EDGAR Public domain filings; SEC fair access https://www.sec.gov/os/accessing-edgar-data | filing registry | T0 | 2026-07-29 21:53 UTC | 3,167 |
Web research (agent-verified) Domains + press dates verified per-company by research agents; URLs stored | media | T2 | — | 0 |
Planned next: UK Companies House (T0), SBIR/STTR grant awards (T0), accelerator batch pages (T3). LinkedIn and X are link-out-only corroboration (T4) by policy — we do not bulk-scrape them.
