Founder
Outreach angles
- -Arinna was founded by two Stanford PhD researchers who developed a brand new ultrathin solar panel material during their doctoral work - the product is built on proprietary deep research rather than incremental engineering.
- -The startup is targeting the space power problem at a moment when nation states and billionaires are racing to expand orbital infrastructure, creating urgent demand for lightweight, high-efficiency energy solutions.
- -CEO Koosha Nazif and CTO Alex Shearer bring rare combined founder profiles - both are Stanford-trained materials scientists turned commercial builders, which is unusual in a hardware-heavy deep tech space.
