Odyssey Venture Partners

Thanasis Kalekos and Spyros Trachanis are the firm's general partners and lead investment decisions. Kalekos brings three decades of operating and venture experience from Cadence and Telos Venture Partners; Trachanis has invested in Greek technology companies since 1999 and co-founded two earlier venture firms, Oxygen Capital Ventures and NBGI Ventures. Venture partner Nikolas Pisanias participates in due diligence, particularly on fintech and bioinformatics opportunities.

Odyssey leverages its dual-office structure — Athens and Santa Clara — to identify Greek engineering teams through local networks while benchmarking them against US technology standards. The firm states it sees two or more investable Greek companies each week. Kalekos's Silicon Valley relationships also surface teams that benefit from US market entry support.

Odyssey is a venture capital firm structured as an asset manager, not a family office. Its first fund, Odyssey Jeremie Partners, raised capital from institutional limited partners including the European Investment Fund and Eurobank Ergasias. The firm does not manage a single-family's wealth.

Odyssey makes direct equity investments into startups. Its publicly disclosed activity focuses entirely on direct company positions — including Acromove, Mantis, Classter, Econais, and Tripsta — with no indication of fund-of-funds commitments.

Odyssey invests across seed, start-up, and growth stages, with a primary focus on early-stage Greek ICT companies. The fund's stated strategy targets ventures that 'disrupt or enable traditional industries' from an initial Greek R&D base.

Odyssey does not publish an explicit exclusion list. Its strategy is concentrated on information and communication technology, with portfolio evidence spanning enterprise software, fintech, semiconductors, and internet platforms. Sectors outside ICT, such as life sciences or hard industrials, do not appear in its portfolio.

Odyssey does not publicly disclose a co-investment program. Given its single-fund structure and the 2016 conclusion of the Jeremie fund's investment period, current syndication partners — if any — are not identified in available disclosures.
