What Arinna does
Arinna is a private, seed-stage space solar technology company founded in 2023 and headquartered in South San Francisco. It was founded by two Stanford PhDs, Koosha Nazif (CEO) and Alex Shearer (CTO), to develop ultra-thin, flexible photovoltaic cells based on transition metal dichalcogenide (2D semiconductor) materials, claiming 10x higher power-per-mass than legacy solar, up to 32% efficiency, 15+ year in-orbit lifespan without cover glass, weeks-long production lead times, and 6x lower cost than silicon-based alternatives.
The company's core product is a single line of ultra-thin flexible solar panels targeted at space-infrastructure applications, including low-Earth-orbit satellites, deep-space missions, and future space data centers. Its technology leverages over a decade of underlying semiconductor R&D, and the company plans to validate its panels in orbit before the end of 2026 and scale to a megawatt-scale manufacturing facility by 2028.
Arinna operates a B2B hardware sales model via direct enterprise sales and customer pilots, targeting satellite operators, spacecraft manufacturers, and defense customers. Strategic partners listed on its website include NASA, the US Army, the NSF, StartX, the Stanford Tom Kat Center, and the Stanford High Impact Technology Fund. The company closed a $4 million seed round in March 2026 led by SpaceCadet Ventures, with participation from Anorak Ventures and Breakthrough Energy Ventures. It is pre-revenue, with 1-10 employees and no publicly disclosed pricing or commercial contracts.

Arinna product offering
Product offeringCore offering
Arinna designs and manufactures ultra-thin, truly flexible solar panels for space applications, using proprietary 2D semiconductor (transition metal dichalcogenide) technology. The panels deliver up to 32% efficiency, 10x higher power-per-mass than legacy solar, and 15+ years of radiation-hard operational life, and are sold to satellite operators, spacecraft manufacturers, and space infrastructure operators. Arinna targets a planned megawatt-scale manufacturing facility by 2028 to serve the projected 3 GW on-orbit solar demand by 2035.
Product overview
Arinna offers a single unified product: its proprietary ultra-thin, flexible solar panel technology based on 2D semiconductors (transition metal dichalcogenides). This technology provides 10x higher power-per-mass compared to legacy solar, up to 32% efficiency, 15+ year operational lifetime in orbit, and ultra-flexibility that allows it to bend tightly and minimize stowed volume. The company targets the growing space infrastructure market, where it aims to replace legacy multi-junction and silicon solar technologies with a more cost-effective, durable, and rapidly producible alternative. Arinna plans to scale production to a megawatt-scale manufacturing facility by 2028.
