Why filter by San Diego

San Diego portfolios often mix biotech, defense, and trade-facing entities. A city filter keeps southern California coverage focused on the principals you care about instead of every coastal California filing.

What we cover

  • Entity status changes — Active, Suspended, Forfeited, Dissolved
  • Franchise Tax Board standing and Secretary of State standing fields
  • Registered agent standing and suspension dates
  • New formations (`INSERT`) and standing updates (`UPDATE`)
