As an adolescent, Bradley Rothenberg was obsessive about CAD: computer-aided design software program.
Earlier than he turned 30, Rothenberg channeled that curiosity into constructing a startup, nTop, which at this time affords product builders — throughout vastly completely different industries — quick, extremely iterative instruments that assist them mannequin and create modern, usually deeply unorthodox designs.
One among Rothenberg’s key insights has been how carefully iteration at scale and innovation correlate — particularly within the design house.
He additionally realized that by creating engineering software program for GPUs, quite than CPUs — which powered (and nonetheless energy) nearly each CAD software — nTop may faucet into parallel processing algorithms and AI to supply designers quick, nearly limitless iteration for any design mission. The end result: virtually limitless alternatives for innovation.
Product designers of all stripes took notice.
A decade after its founding, nTop — a member of the NVIDIA Inception program for cutting-edge startups — now employs greater than 100 individuals, primarily in New York Metropolis, the place it’s headquartered, in addition to in Germany, France and the U.Ok. — with plans to develop one other 10% by yr’s finish.
Its computation design instruments autonomously iterate alongside designers, spitballing completely different digital shapes and potential supplies to reach at merchandise, or components of a product, which can be extremely performant. It’s design trial and error at scale.
“As a designer, you steadily have all these competing objectives and questions: If I make this variation, will my design be too heavy? Will it’s too thick?” Rothenberg mentioned. “When making a change to the design, you wish to see how that impacts efficiency, and nTop helps consider these efficiency modifications in actual time.”

U.Ok.-based grocery store chain Ocado, which builds and deploys autonomous robots, is considered one of nTop’s largest prospects.
Ocado differentiates itself from different giant European grocery chains by its deep integration of autonomous robots and grocery choosing. Its office-chair-sized robots pace round large warehouses — approaching the dimensions of eight American soccer fields — at round 20 mph, passing inside a millimeter of each other as they choose and type groceries in hive-like constructions.
In early designs, Ocado’s robots usually broke down and even caught hearth. Their weight additionally meant Ocado needed to construct extra strong — and dearer — warehouses.
Utilizing nTop’s software program, Ocado’s robotics group shortly redesigned 16 important components in its robots, slicing the robotic’s general weight by two-thirds. Critically, the redesign took round every week. Earlier redesigns that didn’t use nTop’s instruments took about 4 months.

“Ocado created a extra strong model of its robotic that was an order of magnitude cheaper and sooner,” Rothenberg mentioned. “Its designers went by these speedy design cycles the place they may press a button and your complete robotic’s construction could be redesigned in a single day utilizing nTop, prepping it for testing the subsequent day.”
The Ocado use case is typical of how designers use nTop’s instruments.
nTop software program runs a whole lot of simulations analyzing how completely different situations would possibly influence a design’s efficiency. Insights from these simulations are then fed again into the design algorithm, and your complete course of restarts. Designers can simply tweak their designs primarily based on the outcomes, till the iterations land on an optimum end result.
nTop has begun integrating AI fashions into its simulation workloads, together with an nTop buyer’s bespoke design information into its iteration course of. nTop makes use of the NVIDIA Modulus framework, NVIDIA Omniverse platform and NVIDIA CUDA-X libraries to coach and infer its accelerated computing workloads and AI fashions.
“Now we have neural networks that may be educated on the geometry and physics of an organization’s information,” Rothenberg mentioned. “If an organization has a particular method of engineering the construction of a automobile, it could possibly assemble that automobile in nTop, prepare up an AI in nTop and really shortly iterate by completely different variations of the automobile’s construction or any future automobile designs by accessing all the information the mannequin is already educated on.”
nTop’s instruments have huge applicability throughout industries.
A System 1 design group used nTop to nearly mannequin numerous variations of warmth sinks earlier than selecting an unorthodox however extremely performant sink for its automobile.
Historically, warmth sinks are manufactured from small, uniform items of steel aligned facet by facet to maximise metal-air interplay and, due to this fact, warmth alternate and cooling.

The engineers iterated with nTop on an undulating multilevel sink that maximized air-metal interplay even because it optimized aerodynamics, which is essential for racing.
The brand new warmth sink achieved 3x the floor space for warmth switch than earlier fashions, whereas slicing weight by 25%, delivering superior cooling efficiency and enhanced effectivity.
Going ahead, nTop anticipates its implicit modeling instruments will drive better adoption from product designers who wish to work with an iterative “associate” educated on their firm’s proprietary information.
“We work with many alternative companions who develop designs, run a bunch of simulations utilizing fashions after which optimize for one of the best outcomes,” mentioned Rothenberg. “The advances they’re making actually converse for themselves.”
