Theodosian

Enterprise data-protection platform that applies file-level AES-256 encryption (using FIPS 140-3 validated cryptography) and persistent, per-file access controls, so security travels with each file across storage and sharing environments for breach resilience and regulatory compliance (including the UK's Defence Cyber Certification (DCC) and US CMMC). Founded in 2025, the company raised $1.3M in pre-seed funding in October 2025, led by Fuel Ventures, with D11Z Ventures, 1818 Venture Capital, Heartfelt and Startup Wise Guys.
