# Voltron Data

> Voltron Data builds Theseus, a GPU-accelerated, composable distributed SQL query engine for petabyte-scale analytics and AI pipelines, and is a major steward of the open-source composable data stack: Apache Arrow, Ibis, Substrait, Arrow Flight SQL, and ADBC. Theseus is distributed embedded through partners rather than as a self-serve public API. Note: the company website (voltrondata.com) is unreachable as of 2026-07-21 (DNS lame delegation); the GitHub organization remains the live public surface.
