nTop Computational Design Platform

nTop is a New York based engineering software company founded in 2015 and backed by about 150 million USD from investors including NVentures, IQT, Insight Partners and Tiger Global. It addresses a core bottleneck in advanced product development: conventional CAD models break when parameters change, so engineering teams can only evaluate a handful of design options, especially for complex lattice and lightweight parts made by additive manufacturing.

The nTop platform defines geometry as mathematical functions (implicit modeling) instead of B-Rep surfaces, so fillets, booleans and large parameter changes stay stable without manual repair. Design logic is captured once in notebooks and applied automatically across thousands of variants, which are sent into the customer's own solvers or GPU-accelerated Physics AI for evaluation. Clean STEP, Parasolid, STL and 3MF exports feed CAD, simulation and 3D printing workflows. The company serves more than 400 customers in aerospace, propulsion, motorsports and energy.

• Implicit modeling: geometry defined as mathematical functions stays robust through fillets, booleans and large parameter changes.
• Design space exploration: parametric logic runs automatically across thousands of variants from desktop to cloud.
• Accelerated physics: GPU compute and machine learning shorten simulation feedback from hours to minutes.
• Notebooks for AI: design intent is stored as structured workflows that feed surrogate models and AI agents.
• nTop Engines and Orchestrate: engine-based licensing and distributed runs on a team's own cluster or cloud.
• Clean export: watertight STEP, Parasolid, STL and 3MF output for CAD, CAE and 3D printing.

Vietnamese drone and UAV makers can explore thousands of airframe and propeller variants before prototyping. Precision engineering suppliers serving aerospace and energy customers can design lightweight lattice brackets, heat exchangers and cooling channels for metal 3D printing. Universities and R&D centres can use nTop for Education to train engineers in computational design.

nTop reports 93% faster modeling in a customer case, cutting work from 3 weeks to 2 days, and 400+ design variants evaluated with zero mesh failures. In a test with CoreWeave, 2,400 drone geometry variants were generated with zero geometry failures and evaluated through 12,000 CFD simulations. Engineering know-how is captured as reusable workflows, so expert design logic carries across programs instead of being rebuilt for every project.

Aerospace, energy and automotive engineering teams are moving from a few hand-built CAD options to automated, simulation-driven design space exploration, helped by GPU computing and physics AI. Additive manufacturing makes complex lattices and lightweight structures producible, but they require geometry tools that conventional CAD cannot handle well. In Southeast Asia, growing aerospace component, drone and precision engineering supply chains create demand for such design capability.

Founded in 2015 and headquartered in New York City. Raised about 150 million USD from NVentures (NVIDIA), IQT, Insight Partners, LM Ventures, Haystack, 1517 Fund, Canaan Partners, Tiger Global and Carl Bass. Serves 400+ customers; named customer Specter Aerospace. Collaborated with CoreWeave on a 2026 large-scale CFD throughput test on NVIDIA GPUs. Formerly known as nTopology.
