Frequently asked questions
Who runs investment decisions at Tritemius?
Adrian Fradejas is the Managing Partner and leads investment decisions. The firm maintains a lean partnership structure where all commitments require consensus among the partners, which keeps the portfolio tightly curated. Fradejas' background as a former technical founder informs the firm's assessment of product viability and team composition in early-stage deals.
How does Tritemius source proprietary deal flow?
Tritemius sources heavily through the Spanish and Portuguese technical-founder networks, often meeting teams before they formally fundraise. The partners' own operational backgrounds give them credibility within developer communities and university spinout ecosystems. The firm also co-invests frequently with a small group of Southern Europe-focused funds, including K Fund and Encomenda, which creates a referral dynamic.
Is Tritemius structured as a single family office or does it operate more like a venture firm?
Tritemius operates as a traditional venture capital firm managing external limited partner capital, not as a family office. It raises closed-end funds from institutional and private investors. The firm is registered in Spain and files as a regulated asset manager.
Does Tritemius participate in fund commitments or only direct deals?
Tritemius invests exclusively through direct equity deals in operating companies. It does not make fund-of-fund commitments or allocate to other venture managers. The firm's model depends on direct engagement with portfolio founders, which fund commitments would not provide.
What investment stages does Tritemius typically target?
Tritemius targets pre-seed and seed stages, typically deploying initial checks between €250,000 and €1.5 million. The firm leads or co-leads rounds and reserves capital for follow-on investments in top-performing portfolio companies, as demonstrated by its participation in Bdeo's Series A.
Which sectors does Tritemius explicitly avoid?
Tritemius avoids consumer-facing businesses, hardware-intensive startups, and capital-heavy sectors such as cleantech manufacturing. The firm also excludes life sciences and biotech, staying within its circle of competence in B2B software, AI, fintech, and cybersecurity.
Does Tritemius maintain philanthropic structures, and how are they separated?
Tritemius does not operate a separate philanthropic foundation or impact-investing vehicle. All investment activity flows through the core venture fund. The partners may be involved in charitable activities personally, but those are not structured through the firm.
