Folio Photonics

Folio Photonics Inc. is a Solon, Ohio developer of enterprise-scale optical data archive storage, spun out of Case Western Reserve University. Using advances in materials science, it has built multi-layer optical discs with dynamic write/read capability across layers, which it describes as the first economically viable enterprise-scale optical storage of its kind. Disc capacity was targeted to start at roughly 1TB per disc and 10TB per cartridge with a roadmap to multi-terabyte capacities. The company positions the media as an immutable active archive that lowers upfront cost and total cost of ownership while cutting archive energy consumption, and has raised roughly $28M to date including an $8M Series A.

Materials-science-based multi-layer write/read optical discs that make optical archive storage cost-competitive at enterprise scale, with inherent immutability for cyber resilience and a large reduction in archive energy use versus legacy systems.
