Design Catapult takes the sketch all the way to the shipping box
A hospital cart, a contamination scanner and a cold-brew machine have something in common: Design Catapult. The California firm makes a business of the difficult distance between a clever idea and a product someone can actually use.
The Bottle That Works Like a Mom, From a Team That Ran Medela
A former Medela executive and a Harvard-MBA operator spent more than a decade re-engineering the baby bottle. The pitch is simple: make the bottle behave like the breast so babies stop refusing one for the other.
The Company Behind the Gauge on the Wall
Dwyer Instruments has been making the little pressure gauges bolted to industrial walls since 1931. In 2022 it swallowed OMEGA Engineering - a company twice its public profile - and became a measurement conglomerate hiding in plain sight.
Aurorin CAD
Aurorin CAD is building professional mechanical design software from scratch, replacing the 1980s-era geometry kernels inside tools like SolidWorks with a purpose-built, AI-native B-Rep kernel. The result: parts that take an experienced SolidWorks user 20 minutes to model can be created in seconds, either through a fast modern interface or by describing them in natural language to an integrated AI agent. Founded in the Y Combinator Winter 2026 batch by Michael Baron, a former 3x SpaceX intern and Apple GPU driver engineer, Aurorin positions itself as 'Claude Code for mechanical engineers.'
Pantec Group
Pantec Group is a family-owned engineering company based in Ruggell, Liechtenstein, that has grown from a two-person mechatronics shop founded in 1990 into a group of specialized business units spanning industrial automation, motion control, metrology controllers, print-decoration systems and medical laser technology. Its control systems run high-precision machines in printing, textile, semiconductor and coordinate-measuring applications worldwide, while its medical arm, Pantec Biosolutions, develops the P.L.E.A.S.E. laser microporation platform for needle-free, painless drug delivery.
Bild
Bild is a San Francisco cloud PDM/PLM platform that moves hardware design collaboration off email, spreadsheets, and shared drives and into the browser. Founded in 2021 by ex-Apple engineering program manager Pradyut Paul, it gives mechanical and hardware teams version control, check-in/check-out, bill-of-materials, change orders, and secure supplier sharing across multiple CAD formats, plus an AI suite for diffing and searching designs.
Leo AI
Leo AI is a Cambridge, Massachusetts company building what it calls the world's first AI purpose-built for mechanical engineering. Its engineering design co-pilot, powered by a proprietary Large Mechanical Model (LMM) trained on millions of real-world products and engineering standards, turns text, sketches and specifications into production-ready 3D CAD models. Leo integrates with CAD and PDM systems to answer technical questions, source parts, run mechanical calculations and generate design concepts, and says it helps teams cut engineering time by up to 70%.
Aperia Technologies
Aperia Technologies is a Hayward, California hardware-and-software company whose Halo Tire Inflator and Halo Connect platform keep commercial truck tires at the right pressure using only the wheel's rotation. Founded in 2010 by Stanford-trained engineers Josh Carter and Brandon Richardson, the company helps fleets cut fuel use, prevent blowouts, and reduce roadside breakdowns across billions of miles of freight.
