Engineering software firm nTopology Inc. today announced that it has raised $65 million in new funding to expand the type of applications it serves in the product development process and strengthen its global footprint.

Tiger Global led the Series D round. Also participating in the round were Oldslip Group, Root Ventures, Canaan Partners, Haystack and Insight Partners. Including the new funding, nTopology has raised $135 million to date.

Founded in 2015, nTopology offers next-generation design tools designed for engineers in the aerospace, automotive, medical device and industrial design spaces. The company’s software is designed to empower users to find solutions to engineering problems in ways not previously possible in computer-aided design software.

The software is built on three main technologies: implicit modeling, field-driven design and the block system. With the implicit modeling engine, every solid body is described by a single mathematical equation. The company’s “unbreakable” geometry engine enables lightning-fast design integrations that eliminate design bottlenecks in advanced product development.

In April, the company launched nTopology 3.0, which introduced graphics processing unit acceleration to bring down the visualization time of highly complex structures from minutes to seconds. nTopology also collaborated with 3D printer manufacturer Stratasys to further automate the design of manufacturing aids and to streamline the adoption of 3D printing for the factory floor.

The company says its FDM Fixture Generator automates 90% of the design work required for simple jigs and fixtures, while their most recent collaboration, the Masking Fixture Module, eliminates the need for manual masking techniques.

“Earlier in my career, I found that most of the engineering software, like CAD, was a bottleneck in driving innovative design,” Bradley Rothenberg, co-founder and chief executive officer of nTopology, said in a statement. “Our company was built specifically to solve engineers’ problems, allowing them to fully utilize the power of additive manufacturing processes and fill the gaps left by these old legacy design tools.”

The company services more than 300 customers, including Ford Motor Co., Lockheed Martin Corp., Honeywell International Inc., Emerson Electric Co. and the Wilson Sporting Goods Co. In less than a year, nTopology has increased its headcount by about 40% while its revenue doubled, off an undisclosed base.
