Limitations of this cohort

  • Public sources do not verify paid subscriptions, organization-wide deployment or purchasing intent.
  • Source retrieval dates record access; they do not make an older statement or historical deployment current.
  • Published contact channels do not establish outreach permission, mailbox deliverability or purchasing authority.
  • Supplier and historical disclosures retain their source and age limits; they are not proof of continued use.
  • The cohort is not complete coverage. Public signals and vendor statements do not prove current paid use, runtime execution, buying intent, deliverability or outreach permission.
  • Source-fetch dates do not refresh historical customer stories or retained observations. Recheck a company's present use before acting.
