Sources: company job boards (daily), SEC EDGAR, USAspending.gov, and the reviewed technology spreadsheets. Public records only cover US entities, so foreign companies and private firms that don't file will show gaps.
Read from SEC 8-Ks (bankruptcy, default, delisting, restatement, impairment, restructuring), cash runway in annual reports, Form D raises and the 30-day hiring trend. A prompt to look closer, not a credit rating.
No public job board on Greenhouse, Lever or Ashby, so hiring isn't tracked for this company yet.
