nTop

The story of nTop began in 2015, born from a realization that the engineering tools of the past were no longer sufficient for the manufacturing capabilities of the future. Founder Bradley Rothenberg, with a background in architecture and computational design, recognized a critical gap: while advanced manufacturing technologies like 3D printing were unlocking new possibilities for complex geometries, traditional CAD software was holding engineers back. These legacy tools, built on boundary representations (B-reps), struggled to handle the intricate lattice structures and organic shapes that additive manufacturing made possible. Driven by this insight, Rothenberg set out to build a new kind of design platform—one based on implicit modeling that could represent geometry as mathematical equations rather than surfaces.

What started as nTopology has since evolved into nTop, a leading engineering design software company headquartered in New York City. By shifting the paradigm from drawing parts to computing them, nTop has empowered engineers in the aerospace, automotive, medical, and consumer product industries to create mission-critical components that were previously impossible to design. From lightweight satellite brackets to patient-specific medical implants, the platform enables rapid iteration and optimization, collapsing development timelines from weeks to days. Today, nTop stands at the forefront of the computational design revolution, helping the world's most innovative engineering teams deliver higher-performing products with unprecedented speed and reliability.
