Today we are excited to launch Kara, backed by @ycombinator (S26).
We grow ultra-high-purity diamond wafers for AI chips, spacecraft, RF systems, lasers, and quantum hardware.
Diamond can move heat 5× faster than copper, helping the world’s most power-dense systems run harder and cooler.
But thermal management is only the beginning.
Silicon transformed computing when we learned to manufacture it with extreme purity and control. Kara is doing the same with diamond.
Today, our ultra-high-purity diamond pulls heat away from silicon chips. Tomorrow, Kara’s control over purity and defects unlocks diamond as the ultimate semiconductor.
Kara is building the diamond age.
