Hestus Raises $7.4 Million in Funding to Bring Artificial Intelligence to Mechanical Engineering – Unite.AI

A mechanical engineer can know exactly what a part needs to do and still spend hours translating that intent into sketches, dimensions and constraints. Hestus is betting that AI can do more of this repetitive work and has raised a $7.4 million seed round build an ad hoc model for mechanical engineering.

The San Mateo company announced the financing on October 2, with Insight Partners leading the round and participation from Chalfen Ventures, Rock Yard Ventures, Garage Capital and other investors. Combined with an earlier $1.5 million pre-seed round, the funding brings Hestus’ total raised to $8.9 million.

Hestus plans to expand its engineering team to include experienced machine learning engineers and software developers, advance its model and accelerate product development. The company says more than 5,000 engineers already use its tools in projects including drones, robots, industrial equipment and consumer products.

From CAD auto-completion to machine intelligence

Hestus calls his broader ambition “Mechanical Intelligence”: a model designed to capture and apply the judgment involved in turning an engineering idea into something that can actually be produced. This is a more challenging goal than producing a plausible-looking shape. Mechanical design must link geometry to the constraints of a physical product and its manufacturing process.

“Hardware companies should not grow by hiring more engineers to do the work that their design tools are supposed to handle,” said Sohrab Haghighat, co-founder and CEO of Hestus, in the announcement. “We are building AI that can translate engineering intent into actionable designs, allowing engineers to focus on the creative decisions that move products forward.”

The company’s current product offers a concrete starting point. The Hestus website describes an autocomplete-style assistant that works within Autodesk Fusion on Mac and Windows. As an engineer draws, he or she proposes possible next actions rather than requiring the user to leave the CAD environment. The website also offers an alpha recording of SolidWorks.

There is an important distinction between the available product and the broader vision. In its product philosophy, Hestus describes Sketch Helper as focused on 2D design and sketching, with more comprehensive 3D assembly and design-for-manufacturing capabilities planned for future expansion.

What technology does inside a sketch

The company’s release notes make the workflow more tangible. Its suggestion system considers the current state of the sketch and the engineer’s interactions, then presents suggested changes in overlay. Engineers can accept a recommendation, cycle through alternatives, or ignore it and continue designing.

Examples include recognizing an axis of symmetry and suggesting mirrored geometry, aligning circular elements horizontally or vertically, and connecting dangling endpoints to help close a profile before an extrude or revolve operation. The tools also fix missing dimensions on lines, circles, and arcs.

These are small operations taken individually, but which are repeated during a design session. Hestus’ approach is to reduce the interface work surrounding an engineer’s decisions while maintaining control of what suggestions go into the model.

Kyle Faller, mechanical engineer, co-founder and CEO of Intelline, described this benefit in the funding announcement: “Hestus deploys easily and delivers immediate value by eliminating repetitive mechanical design workflows.” Its report represents the customer experience, rather than an independent productivity benchmark, but illustrates the workflow the company is targeting.

A founding team with experience in autonomous systems

Haghighat and co-founder and CTO Kevin Chu met at Cruise Automation, where the ad says they were among the first 10 employees and helped develop its self-driving technology.

Chu earned a doctorate in robotics from UCLA and helped grow Cruise’s autonomous vehicle engineering organization from 20 to 300 people before later leading software engineering at Mendaera. Haghighat earned a doctorate in aerospace engineering from the University of Toronto and later founded SpaceRyde. Their background combines software, robotics, and the difficulties of building systems that must function in the physical world.

For investors, the opportunity goes beyond the acceleration of individual CAD commands. Daniel Dart, managing partner of Rock Yard Ventures, argued in the announcement that production capacity depends on a prior bottleneck: Products must first be designed, controlled, tolerated and made producible.

The next test goes beyond the fastest click

The round is part of a broader investment push towards artificial intelligence within engineering and manufacturing workflows. These applications require AI to work with specialized tools and physical constraints, where an attractive outcome alone is not enough.

For Hestus, the immediate opportunity is to make repetitive sketching work less time-consuming. The biggest challenge is extending that assistance to reliable engineering judgment in assembly and manufacturing decisions. Its seed funding provides the team with the resources to pursue that transition; the current sketch assistant provides a practical foundation from which to build.
