Skybound Launches $38M Athens-Based Deeptech Fund Anchored by EIF, Bets First on BCI Startup
TL;DR
Athens-based Skybound has officially launched with a $38M oversubscribed first close, anchored by the European Investment Fund, to back pre-seed and seed-stage deeptech founders across infrastructure, advanced computing, bioengineering, and frontier technologies. Co-founded by Thaleia Misailidou, formerly of Marathon Venture Capital, and George Varvarelis, co-founder of Augmenta (acquired by CNH Industrial), the fund is a notable bet that southern European deeptech can produce globally relevant outcomes. The first investment is in Neurosoft Bioelectronics, a brain-computer interface company.
Key Takeaways
EIF as anchor is the validation seal Greek VC needed. The European Investment Fund is the most disciplined institutional LP in European venture, and its anchor in a Greek-led deeptech vehicle signals confidence in both the team and the ecosystem. Marathon Venture Capital opened that door for Greece in 2017; Skybound is the next step in formalizing the country as a credible VC destination rather than a feeder for Berlin and London.
Operator-VC pairing is the right combination for deeptech. Misailidou comes from the investing side at Marathon; Varvarelis has actually built and sold a deeptech company. That blend of capital and operating credibility is exactly what early-stage hardware and frontier-tech founders need from a lead investor, and it is a meaningfully differentiated team profile against Greek and southern European peers.
$38M is small by purpose, not by accident. A concentrated $38M fund with $500K to $2M initial cheques and meaningful follow-on reserves is the cleanest possible vehicle for pre-seed and seed deeptech. Smaller fund size forces discipline, and the team can credibly own significant ownership stakes in 15 to 20 portfolio companies, where every winner moves the fund.
Brain-computer interface as the debut deal sets the tone. Leading the first investment into Neurosoft Bioelectronics, a BCI company, is a sharp early signal that Skybound is willing to underwrite hard-science risk that most generalist seed funds will not touch. That positioning will define how founders perceive the fund's appetite over the next 24 months.

Why This Fund Matters
Southern European deeptech is still an underexplored category in pan-European VC. Most of the institutional capital that flows into European deeptech ends up in Munich, Paris, London, Stockholm, and Amsterdam. Athens, despite producing strong technical talent and credible Founders like the Augmenta team that Varvarelis was part of, has historically lacked a dedicated seed-stage deeptech vehicle with the LP backing to write meaningful first cheques.
Skybound is built to change that dynamic. The fund's positioning at the pre-seed and seed level, with $500K to $2M initial cheques, is exactly where Greek and broader southern European deeptech founders typically face the most friction. The combination of EIF's institutional anchor and Misailidou's track record at Marathon Venture Capital, one of the few Greek funds with a credible LP base, gives Skybound a structurally advantaged position to lead these rounds.
The deeptech angle is also strategically right for this moment. As AI infrastructure, advanced computing, and bioengineering see record interest from generalist VCs, the seed-stage talent pool for technically complex companies has grown. Specialist funds with operator-led teams and disciplined cheque sizing tend to outperform generalist seed funds in deeptech precisely because hard-science underwriting requires conviction that generalist firms struggle to develop.
The risk is concentration. A $38M fund will likely build a portfolio of 15 to 20 companies, and the fund's outcome is binary on whether one or two of those bets become breakout winners. That is the standard early-stage deeptech math, but it is worth noting that Greek and southern European deeptech exits at significant scale are still rare. Augmenta's acquisition by CNH Industrial is a recent positive datapoint; Skybound will need several more like it across the next decade to anchor a successor fund.
The Team
Thaleia Misailidou serves as general partner. She joined Marathon Venture Capital, one of the leading Greek venture firms, and built a track record investing across the southern European seed landscape. Her network within the Greek and broader Mediterranean deeptech ecosystem is one of the deepest in the region, and her time at Marathon gives her direct underwriting experience with EIF as an LP.
George Varvarelis brings the operator side of the team. He co-founded Augmenta, an agritech deeptech company that built AI-powered crop spraying technology and was acquired by CNH Industrial. That exit, completed in 2023, gave Varvarelis hands-on experience with the full lifecycle of a deeptech startup, from early seed financing through scaled commercial deployment and strategic acquisition. Founders pitching Skybound get an operator who has been on their side of the table.
Early Portfolio
Skybound's announced debut investment is in Neurosoft Bioelectronics, a company developing scalable and minimally invasive brain-computer interfaces. That investment landed the same week as the fund launch, and it is a high-conviction signal about Skybound's appetite for technically ambitious bets. Additional portfolio investments have not yet been publicly disclosed.
What This Means for Founders
If you are building a deeptech company in Greece, Cyprus, Italy, Spain, Portugal, or anywhere across southern and southeastern Europe, Skybound is now the most relevant new seed-stage fund in your geography. The team is willing to lead rounds in technically complex hardware, advanced computing, and bioengineering categories that most generalist seed funds would pass on. The combination of EIF backing and operator-led GPs makes Skybound a meaningful cap-table addition that can also help recruit follow-on capital from larger pan-European funds.
Skybound is less likely to be the right fit for vertical SaaS, consumer apps, or fintech without a meaningful technical wedge. The team's pattern recognition is biased toward founders who can credibly defend a hard-science or frontier-engineering moat, and that is the bar founders should expect to clear.
Fund Momentum Take
Skybound is a structurally well-designed fund. The $38M size matches the team's stage focus, the GP combination of investor and operator backgrounds is the right pairing for deeptech, and the EIF anchor solves the institutional credibility problem that often constrains southern European emerging managers. The fund is also tactically smart to debut with a hard-science investment in Neurosoft, which sets immediate expectations about the kind of bets Skybound will underwrite.
The honest risk is that southern European deeptech still has not produced enough Series B and beyond exits to validate a multi-fund franchise. Skybound's success will depend on whether its portfolio companies can attract pan-European follow-on capital quickly enough to scale, and whether the fund itself can raise a successor vehicle once initial deployment is complete. The Marathon Venture Capital franchise is the proof point that this is possible from Athens, but Skybound will need its own breakout returns to consolidate that thesis.
Our bet is that Skybound becomes one of the most relevant new emerging managers in Europe over the next 24 months. The team has the right credentials, the right LP base, and the right thesis at exactly the moment that deeptech is becoming a central category in European venture. Worth tracking closely.
