Buildings don’t breathe, think, or hustle, until someone like Troy Aaron Harvey decides they should. PassiveLogic just secured a $74 million Series C led by noa in London, with Prologis Ventures, Johnson Controls, and PSP Growth joining the table, alongside returning investors Addition, NVIDIA’s NVentures, Keyframe Ventures, and Brookfield Ventures. That pushes total funding past $124 million since 2016, and this latest raise isn’t luck, it’s the result of vision backed by execution.
PassiveLogic has been crafting the future of the built world with technology that doesn’t just optimize, it teaches buildings to think for themselves. The Hive Platform isn’t another gadget bolted to a boiler room wall. It’s a full-stack autonomy engine, edge-deployed controllers powered by NVIDIA processors, a wireless sensor web, and Quantum, a physics-based digital twin that doesn’t need cloud babysitting to make smart, real-time decisions. Hospitals, data centers, and industrial campuses are already showing 30% energy savings, and that’s just the pilot phase.
The foundation comes from Troy Aaron Harvey, an engineer who mastered embedded systems before climate tech was cool. The execution comes from Jeremy Fillingim, Co-Founder and CTO, who built the Quantum digital twin framework into something that can model, simulate, and command buildings without waiting on server farms. Together they turned “building management” into “building autonomy,” a phrase that carries both weight and inevitability.
Series C isn’t just a cash infusion. It’s validation from a lineup of investors who don’t chase science projects. noa is Europe’s largest built-world VC. Prologis runs warehouses across the planet. Johnson Controls knows more about HVAC than anyone alive. NVIDIA doesn’t just put chips in boxes, they bet on platforms with gravity. When these names move, it signals a trillion-dollar market coming into focus.
The plan for the new capital is precise: expand into Europe and Asia Pacific, scale manufacturing for Hive hardware, and accelerate R&D on Quantum’s next iteration. The Quantum API is about to open the ecosystem to developers, a move that could do for building automation what iOS did for mobile. Industrial automation and smart cities are next. With foundational patents already in hand around digital twin ontology and autonomous control, PassiveLogic isn’t just competing, it’s defining the lane.
This is more than another round. It’s the moment the built environment starts running on intelligence, not inertia. PassiveLogic just made that future unavoidable.
