name: Habeas
description: Habeas was an email reputation and deliverability services provider that helped legitimate
  senders monitor and manage their sending reputation to maximize inbox deliverability, using a trademark-based
  accreditation and safelist model to certify permission-based email. Founded in the mid-2000s and backed
  by Canaan Partners through a Series B round, Habeas was acquired by Return Path in 2008 (habeas.com now
  redirects to returnpath.com); Return Path was in turn acquired by Validity in 2019. The company is
  defunct as an independent brand and publishes no live public API or developer surface, so this profile
  is retained as a Canaan Partners portfolio-history record rather than an active API provider.
