What nTopology does
nTop (formerly nTopology) is a New York-based computational design software company founded in 2015 by Bradley Rothenberg. It develops the nTop platform, which uses a proprietary implicit modeling kernel — a fundamentally different mathematical foundation from traditional boundary-representation CAD — to enable engineers to create complex geometries (lattices, topology-optimized structures, lightweighted parts) without the fragility and rework common to legacy tools. The platform embeds FEA and CFD simulation in the design loop, supports 'unbreakable' parametric models, and exposes a developer API (nTop Core) for partners to natively read *.implicit files. The latest major release, nTop 5 (June 2024), is a ground-up kernel rebuild paired with an expanded integration ecosystem spanning simulation (Hexagon scSTREAM, Intact.Simulation, SimScale, cloudfluid), manufacturing (Materialise Magics, NxG Build Processor), CAD (Autodesk Fusion), and physics-based AI (Luminary Cloud, NVIDIA PhysicsNeMo).
The company serves enterprise engineering teams across aerospace and defense (Lockheed Martin, Specter Aerospace), automotive (Ford), industrial and energy (Wärtsilä, Ocado Technology), medical devices (Synopsys Simpleware, Not a Robot Engineering), and consumer goods (Cobra Puma Golf), with active customers in 30+ countries. Its go-to-market is enterprise field sales with quote-based annual subscriptions (named-user and floating licenses), augmented by an annual Computational Design Summit, an education program (nTop Ed), and partner-driven distribution through the Autodesk Fusion App Store. Documented customer outcomes include 15-20% weight reduction and 10-15% heat dissipation improvement on Lockheed Martin hypersonic/aircraft thermal management parts, and a 60% weight reduction on a Wärtsilä 3D-printed cylinder head.
nTop has raised approximately $135 million in venture funding, most recently a $65 million Series D led by Tiger Global in November 2021, and operates as a private Delaware-incorporated corporation. The company is subject to U.S. export control (ITAR) compliance and explicitly serves ITAR-sensitive aerospace and defense customers. It rebranded from nTopology to nTop and acquired cloudfluid (GPU-based CFD) in 2024-2025 to extend its design-to-manufacturing workflow.
