description: 'E-Stamp Corporation (eStamp) was a dot-com era Internet-postage company, a Canaan
  Partners seed-stage portfolio company that competed with Stamps.com to let users buy and print
  official U.S. Postal Service postage online. The company is defunct: on April 30, 2001 Stamps.com
  acquired E-Stamp''s name, 31 Internet-postage patents, and the estamp.com domain, which today
  301-redirects to stamps.com. There is no live company, product, developer portal, or API surface
  to enrich; this profile is retained as a historical portfolio-lead record.'
