UK cybersecurity startup Theodosian, which develops file-level encryption and compliance tools, has raised $1.3m in pre-seed funding led by Fuel Ventures.
The round also saw support from D11Z Ventures, 1818 Venture Capital, Heartfelt, Startup Wise Guys and several angel investors. The investment will help the company advance its mission to protect enterprises from growing data breach risks and meet tightening cybersecurity regulations.
Founded by experienced cybersecurity specialists, Theodosian provides persistent, per-file protection that moves with data, ensuring it stays secure wherever it travels. The platform enables enterprises to set permissions and run compliance checks on every document, helping meet new UK and US standards such as Defence Cyber Certification (DCC) and Cybersecurity Maturity Model Certification (CMMC).
The funding will be used to complete version 1 of its platform and expand its customer base as it prepares for commercial launch.
Fuel Ventures founder Mark Pearson said: “Theodosian is building the next generation of enterprise cybersecurity, protecting data at the most granular level while keeping compliance at the forefront. The team’s deep expertise in cybersecurity and risk management makes them ideally positioned to tackle this challenge, and we’re thrilled to support them at this early stage.”
Theodosian co-founder Andy Johnson commented: “We started Theodosian to address a critical gap in enterprise security, protecting every file individually, wherever it goes. Our platform goes beyond traditional encryption, offering persistent, per-file dynamic access controls, detailed permission management, and continuous verification to ensure only the right people can access sensitive data. With Fuel Ventures’ support, we can bring these capabilities to market quickly, helping companies comply with regulations, including new DCC standards, and significantly reduce the risk of data breaches.”
Co-founder Brendan Diaz added: “This funding allows us to not only introduce a new approach to data security to the market, but to focus on delivering tangible value to our customers. By giving enterprises and security teams granular control over files, reducing the risk of breaches, and simplifying day-to-day security management, Theodosian lets teams focus on what matters most while ensuring sensitive data stays protected wherever it travels.
“Our goal is to make enterprise security effortless and reliable, so teams can collaborate with confidence and compliance is always built in.”
