About nTop

nTop, formerly known as nTopology, is a New York-based software company developing next-generation engineering design tools for advanced manufacturing. Founded in 2015 by CEO Bradley Rothenberg and Greg Schroy, the company was established to address a gap in the market where traditional CAD software could not handle the complex geometries demanded by modern engineering and 3D printing. Rothenberg, with a background in architecture from Pratt Institute, conceived the idea while consulting for Lockheed Martin, recognizing that manufacturing was no longer the bottleneck, but rather the software was limiting design innovation.

The company's core product, the nTop platform, is a computational modeling software that enables engineers to design, test, and iterate on highly complex parts with speed and efficiency. It utilizes an implicit modeling kernel, which represents 3D solids with mathematical equations, allowing for the creation of intricate structures like lattices, architected materials, and topology-optimized parts that are often lighter and higher-performing. This technology is particularly suited for additive manufacturing but also supports other advanced methods like molding, milling, and casting. The platform integrates with existing design, analysis, and simulation tools such as ANSYS, Abaqus, and Nastran, streamlining the entire workflow from concept to production.

nTop serves a range of industries including aerospace, automotive, medical devices, and consumer products. Its client roster includes prominent organizations like Lockheed Martin, NASA, Raytheon, BMW, and Trek Bikes. The business model revolves around providing its software to engineering teams to accelerate product development and innovation. By automating complex design workflows, nTop enables companies to bring better products to market faster. The company has raised significant funding, totaling over $135 million, to support its growth and expand its platform's capabilities.
