Michael Theodosiou

Michael Theodosiou is an Investment Manager at Symvan Capital, a London-based venture capital fund manager focused on UK technology companies through EIS and SEIS funds. Symvan lists him on its investment team as Investment Manager, and EISA lists him as a contact for Symvan’s open SEIS and EIS offers.

Before venture capital, Theodosiou studied English at UCL, completed a law conversion course, trained as a barrister, received an LLB, and was called to the Bar. His LinkedIn profile lists the University of Law from 2011 to 2013, along with CISI and BVCA certifications including CISI Level 3 Certificate in Securities, BVCA Due Diligence, and CISI Sustainable and Responsible Investment.

He moved from law into an EdTech startup, which he has described as a turning point because it was dynamic, forward-looking, and focused on creative problem-solving. A chance introduction to Symvan’s founders led to what he expected to be a short internship; he now describes himself as having been in VC for more than 10 years.

At Symvan, he works across sourcing, filtering, due diligence, term negotiation, investment recommendations for the Investment Committee, and ongoing portfolio support. His public London Tech Week profile says he is most involved in engaging with existing portfolio companies and supporting them as they grow.

• Symvan invests in high-growth UK technology companies, backing founders from pre-seed to scale through EIS and SEIS structures.
• The firm’s stated founder-facing focus is B2B enterprise solutions that solve real-world problems and use AI or other enabling technologies.
• Symvan typically looks for S/EIS-qualifying companies with an MVP, initial traction, a clear go-to-market strategy, a large addressable market, strong founder execution capability, defensible technology or IP, and scalability.
• The firm often leads rounds at SEIS and early EIS stage and also co-invests with angel syndicates, VCs, and institutional investors.
• Symvan’s fund model uses staged or tranche investing, lifecycle support, follow-on capital, strategic guidance, network access, and exit structuring.
• Theodosiou’s early-stage lens is founder-centric. In a 2025 founder write-up, he was quoted saying: “If this doesn’t work, can they make something else happen?”
• Founder attributes Symvan says it values include resilience, conviction with humility, sector knowledge, and clarity of vision and purpose.
• Symvan’s approach emphasizes active downside management as well as upside: the firm says it focuses on finding winners while actively managing risk, intervening where possible, and knowing when to step away.
