“Let me roll up your industry.”
A fragmented industry, China’s 2025 export controls, a platform already shipping, and an operator who has done this before.
The case in brief
The thesis
Many small players, aging owners, no standard-setter.
The equipment and know-how every player needs and nobody owns.
Integrate, standardize, and let every addition strengthen the whole.
The problem
Fragmentation is the opportunity. Exposure is the urgency.
Why now
China controls rare earths and rare-earth magnets. MOFCOM Announcement 18.
Expanded, for the first time, to magnet-making equipment and technology.
Arcline’s DwyerOmega platform acquires Lake Shore Cryotronics.
The West needs a non-China magnetics supply chain. Consolidators are already moving.
The platform
A MagPrinter prints tiny polarized “maxels”, magnetic pixels, into a single magnet. It can do what a conventional magnet cannot.
The roll-up math Illustrative
Small private industrial firms often trade around 4–7x earnings; scaled platforms, roughly 12–20x. Buying fragmented and integrating onto one platform is how that gap is captured.
Illustrative onlyTypical ranges, not a valuation, forecast or promise of returns.
Public comparables
Serial acquirers in instruments show the model public investors already reward. Private capital is running the same play now. We bring it to magnetics.

Proprietary sourcing
Each graded on a live audit of its own web presence. Weak presence means the most upside. Target map, competitive map and lead list in one.
The operator
Walk into an industry that is stuck. Change how it works.
Helped launch the EV1, the first modern electric car.
Transformed how the industry manufactures: craft to lean flow production.
Put rival national homebuilders on one shared technology platform.
Building the platform for Western magnetics.
The proof
In 2000 he founded Builder Homesite as a consortium of rival national homebuilders, and got fierce competitors onto one shared technology platform.
