Causera

Causera was an early-stage Palo Alto, California startup surfaced as a 500 Global (500 Startups) portfolio company. Enrichment probing found no operating public surface: the company's own domain, causera.com, resolves to a GoDaddy parked-domain lander rather than a product site, and the only verified live property is the dormant "Causera Engineering" GitHub organization (github.com/causera, created 2011-06-22), which holds a single public repository — a fork of mbleigh/princely, a Rails wrapper for the PrinceXML PDF library — last pushed in August 2011 with no public members. Causera therefore appears to be a defunct 2011-era company with no developer portal, no documentation, no API, and no published specifications. This profile records the negative result so future enrichment rounds do not re-probe from scratch.

Causera is profiled on the APIs.io network. Tagged areas include Company, Startup, 500 Global, Portfolio, and Defunct.

x-status-evidence: causera.com serves a GoDaddy parking lander (window.LANDER_SYSTEM=PW, _trfd ap:"parking"); github.com/causera
  dormant since 2011-08-02; no package-registry or well-known surface found.
x-source-url-mismatch: The 500 Global portfolio scrape (500-global/portfolio/500-global-portfolio.yml) paired the name "Causera"
  with https://simplycircle.com. That domain 301-redirects to https://www.konstella.com/ — a PTA/PTO communication product
  with no stated link to Causera. The pairing is unverified and is NOT treated as Causera's website; causera.com (declared
  as the blog URL on the Causera Engineering GitHub org) is used instead. Retained here for provenance only.
