Microsites started from a simple observation: people rarely want another static PDF if the information inside that PDF actually matters. The more important the content is, the more damaging it becomes when navigation, readability, and update cycles are all trapped inside a file.

Key Results

  • More than 600 Microsites became proof that the model scales beyond a one-off experiment.
  • The product created a much stronger public story around document intelligence and interactive publishing.
  • Microsites now serves as one of the clearest examples of how Subterra turns a recurring delivery pattern into a product.

Challenge

  • Static documents created friction for both publishers and readers.
  • Dense information needed to be easier to browse, update, and share.
  • The team needed a repeatable publishing pattern that still felt structured and branded.

Solution

Subterra built Microsites to turn documents into web-native experiences.

  • Source material could be transformed into structured pages instead of shipped as attachments.
  • Delivery shifted from file sharing to link sharing.
  • The product combined presentation, structure, and engagement visibility in one publishing workflow.
