Earendil Works
The publisher of Pi. From the GitHub organization profile (API, 2026-08-30): name "Earendil Works", description "Bearer of Light", located in Austria, website earendil.com, 15 public repositories, organization created 2025-04-16 — four months before the Pi repository itself.
That is the whole of the evidence. No company registration, funding, headcount or business model is stated anywhere the corpus has looked, and the site publishes no pricing: Pi is MIT-licensed and the provider keys are the user's own. So there is no visible answer to how a project at ~99k stars is paid for, which is the same blank this spoke records for most of its harnesses.
Mario Zechner is the developer behind it and is likewise in Austria.
