Kara
Making Diamond Semiconductors
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.
