How many public companies does BrokerHQ track in the Puget Sound region?
BrokerHQ tracks 329 public companies with Puget Sound operations as of August 7, 2026. The set is rebuilt daily from SEC EDGAR, so the number moves as companies register, delist, get acquired, or change what their filings disclose about where they operate.
What makes a company count as a Puget Sound company?
A company counts when it is a public filer and its own SEC filings establish operations in the Puget Sound region. The basis is the filing, not a third-party estimate and not a purchased list. If a company's filings do not put it here, it is not in the count, even when a database elsewhere says otherwise.
How quickly does a new filing show up?
Every 10-K, 10-Q, 8-K, S-1 and proxy statement filed by a US public company runs through ingestion within 24 hours of release. Composite signals built on top of those filings are recomputed nightly, so a disclosure that lands on a Tuesday is reflected in the signal set by Wednesday morning rather than the following quarter.
How accurate is the match between a filing and a company?
When BrokerHQ links a record to a company, it is right 97.5 percent of the time, and it catches 88.6 percent of the links that exist. Those figures come from scoring against a golden set of 95 human-verified cases. Uncertain matches are held back for review rather than guessed, which is why recall sits below precision by design.
What can a tenant rep broker actually do with this?
Public filers disclose lease commitments, real-estate footprint changes, restructuring, and material events on a schedule. That makes them the one occupier population whose real-estate intentions are legally required to become public. A broker can see a lease maturity disclosed in a 10-Q, a footprint reduction announced in an 8-K, or a raise filed on Form D, and walk into the meeting citing the filing rather than a rumor.
Why does the number go up and down?
It is a live count, not a marketing figure. Companies enter when they register or when a filing first establishes Puget Sound operations, and leave when they delist, are acquired, or stop disclosing operations here. A count that only ever rose would mean the set was never being pruned.
Which public records does this come from?
Every record below is published by the body that created it, and every link goes to that body rather than to a reseller. You can check any number on this page against them yourself.
- SEC EDGAR full-text search
10-K, 10-Q, 8-K, S-1 and proxy statements. The primary source for the count on this page, and for lease commitments, footprint disclosures and material events.
- SEC EDGAR filing system
The filing system itself, including Form D notices of exempt private offerings.
- USAspending
Federal contracts and grants awarded to companies operating in the region.
- US Department of Labor, foreign labor certification data
H-1B filings, read as a hiring-surge signal alongside live job postings.
- Washington Employment Security Department, WARN notices
Layoff and closure notices filed by Washington employers.
How is the count actually built?
The primary source is SEC EDGAR. A company counts when it is a public filer with operations in the Puget Sound region, established from its own filings rather than third-party estimates. The set is refreshed daily as new 10-K, 10-Q, and 8-K filings post to EDGAR, so companies enter and leave the count as their disclosures change. Every signal derived from a filing must be resolved to one company with the match basis recorded, and needs a second independent source before it surfaces.
