As a teen, 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 right this moment provides product builders — throughout vastly totally different industries — quick, extremely iterative instruments that assist them mannequin and create revolutionary, usually deeply unorthodox designs.
One in all Rothenberg’s key insights has been how intently iteration at scale and innovation correlate — particularly within the design area.
He additionally realized that by creating engineering software program for GPUs, quite than CPUs — which powered (and nonetheless energy) nearly each CAD instrument — nTop may faucet into parallel processing algorithms and AI to supply designers quick, nearly limitless iteration for any design venture. The consequence: nearly limitless alternatives for innovation.
Product designers of all stripes took observe.
A decade after its founding, nTop — a member of the NVIDIA Inception program for cutting-edge startups — now employs greater than 100 folks, primarily in New York Metropolis, the place it’s headquartered, in addition to in Germany, France and the U.Okay. — with plans to develop one other 10% by yr’s finish.
Its computation design instruments autonomously iterate alongside designers, spitballing totally different digital shapes and potential supplies to reach at merchandise, or elements of a product, which can be extremely performant. It’s design trial and error at scale.
“As a designer, you continuously have all these competing targets and questions: If I make this alteration, will my design be too heavy? Will it’s too thick?” Rothenberg mentioned. “When making a change to the design, you need to see how that impacts efficiency, and nTop helps consider these efficiency modifications in actual time.”
U.Okay.-based grocery store chain Ocado, which builds and deploys autonomous robots, is considered one of nTop’s greatest prospects.
Ocado differentiates itself from different giant European grocery chains via its deep integration of autonomous robots and grocery choosing. Its office-chair-sized robots pace round large warehouses — approaching the scale 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 crew rapidly redesigned 16 essential elements in its robots, chopping the robotic’s total weight by two-thirds. Critically, the redesign took round per 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 via these speedy design cycles the place they might press a button and the complete robotic’s construction can 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 lots of of simulations analyzing how totally different circumstances may impression a design’s efficiency. Insights from these simulations are then fed again into the design algorithm, and the complete course of restarts. Designers can simply tweak their designs based mostly on the outcomes, till the iterations land on an optimum consequence.
nTop has begun integrating AI fashions into its simulation workloads, together with an nTop buyer’s bespoke design knowledge 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.
“We have now neural networks that may be skilled on the geometry and physics of an organization’s knowledge,” Rothenberg mentioned. “If an organization has a selected approach of engineering the construction of a automobile, it will possibly assemble that automobile in nTop, prepare up an AI in nTop and really rapidly iterate via totally different variations of the automobile’s construction or any future automobile designs by accessing all the info the mannequin is already skilled on.”
nTop’s instruments have vast applicability throughout industries.
A Method 1 design crew 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 metallic aligned facet by facet to maximise metal-air interplay and, subsequently, warmth trade 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 chopping weight by 25%, delivering superior cooling efficiency and enhanced effectivity.
Going ahead, nTop anticipates its implicit modeling instruments will drive larger adoption from product designers who need to work with an iterative “accomplice” skilled on their firm’s proprietary knowledge.
“We work with many various companions who develop designs, run a bunch of simulations utilizing fashions after which optimize for the perfect outcomes,” mentioned Rothenberg. “The advances they’re making actually converse for themselves.”
