Subtext *

Subtext was a consumer/education social-reading and in-text annotation app backed by GV (listed in GV's portfolio with an asterisk denoting an exited investment). It has since been acquired: as of this enrichment pass the company domain subtext.com 301-redirects to renaissance.com (Renaissance Learning), and no independent website, developer portal, API, documentation, or /.well-known/security.txt could be found. No public API surface exists to enrich; this profile records the verified exit/redirect status and a domain-security probe of subtext.com.

Subtext * is profiled on the APIs.io network. Tagged areas include Company, Consumer, Education, and Acquired.
