About Kara
Summary
Kara grows single-crystal diamond wafers in its own reactors and handles all growth, processing, and characterization in-house. Its engineered diamond targets thermal management, power electronics, RF systems, quantum computing, and photonics, replacing conventional semiconductor materials like silicon, GaN, and SiC in applications where heat dissipation, breakdown tolerance, and carrier mobility are limiting factors. Customers include hardware builders in data centers, aerospace, and quantum hardware who are constrained by the physical ceilings of existing semiconductor substrates.
Go-to-market
Kara sells to hardware developers and system integrators in data centers, space, RF, and quantum sectors, with direct engagement via inquiry through its website.

Making Diamond Engineerable
Kara is building diamond semiconductors. We begin with growing ultra-high purity diamond wafers for advanced hardware. Used in data centers, spacecrafts, RF systems, and quantum hardware, our diamond moves heat up to 5× better than copper, helping critical systems run cooler, faster, and more reliably. Diamond has spent centuries as a symbol. We are turning it into infrastructure.
