PassiveLogic Tech Stack

Physics-based autonomous control platform for building HVAC and energy systems

Software Development Salt Lake City, UT 51–200 employees Founded 2016 Privately Held

PassiveLogic builds autonomous building-control software using physics simulation (Modelica, Dymola, Simscape, MATLAB) and edge-deployed neural reasoning (Neo4j, Weaviate, WebAssembly). The stack reveals a company translating domain expertise in thermodynamics and fluid dynamics into learned control policies — not traditional rule-based automation. Engineering dominates hiring (19 of 27 active roles), with mid- and senior-level concentration, indicating active scaling of control-algorithm development and digital-twin generation rather than sales-led expansion.
