SIO’s CEO Kostis Tselenis will be speaking at Super Return Energy Transition 2026 on 8-9 June at the DoubleTree by Hilton Berlin.

Registration with 10% discount here.

The panel “Perspectives from the capital source: LPs’ evolving interpretations of energy transition” will focus on how LPs are interpreting, defining and allocating capital to energy transition strategies in 2026, and what this means for managers navigating a more competitive fundraising environment.

From the SIO perspective, Energy Transition as a core theme of our Impact Strategy, goes beyond #Renewables as we have expanded the spectrum to include the broader value chain: storage grid capacity agrivoltaics and energy efficiency.

The space has evolved since we did our first pioneering #solartech investments with #GoodEnergies (COFRA Group) to bring down the technology cost and help the market to mature.

The SIO focuses on institutional-quality, market-return impact investing across private markets through funds (semi-liquid, closed-ended) and selected directs.

Looking forward to a great panel with Uwe Fleischhauer, YIELCO Investments that will be moderating, and fellow speakers Matteo Squilloni, European Investment Fund (EIF), and Nigel Purcell, The Irish Strategic Investment Fund.

Our thanks to Informa Connect for organising the discussion.

The invitation-only asset owner session “Unlocking Capital for the Blue Economy” where SIO’s Managing Partner Kostis A. Tselenis is co-moderating, will be one of the key moments of this year’s Blue Economy & Finance Forum in Monaco.

We are looking forward to joining and supporting this high-level dialogue, hosted by Fondation Prince Albert II de Monaco, bringing together family offices, pension funds, sovereign wealth funds, endowments and institutional investors to discuss the barriers, structures and pathways needed to scale investment into the blue economy.

For us a highly relevant conversation, as Blue Economy, #CircularEconomy and #NatureFinance are core areas of our broader investment focus, alongside the need to create dedicated Impact #LPConsortia with fellow investors to anchor best-in class thematic strategies.

Beyond the private session, the wider Forum brings an exceptional Agenda on innovation, blue foods and mobilization of capital among others.

Looking forward to contributing to the discussion and reconnecting with peers across the ecosystem.

PANEL I: Institutionalisation of Impact Investing

PANEL II: Financing the Transition: Food Systems, Nature & Real Economy Impact

Event details here

The event brought together a diverse investor-linked audience and top specialists to discuss how #ImpactInvesting is moving from niche to core allocation, and how #Nature, #FoodSystems and real economy strategies can absorb more institutional #PrivateCapital.

Key takeaway: #ImpactInvesting is no longer a niche conversation. The question is now how to institutionalise it without diluting its purpose.

Reflections from the first panel moderated by Kostis A. Tselenis, Swiss Impact Office:

Nadina Stodiek, Schroders, reminded us that #ImpInv is already “established, accessible and profitable”. Next step: #scale, through strong partnerships with specialised players who can grow assets without compromising integrity.

Sinisa Vukic, Cardano, pointed to one of the key barriers: perceived #risk. Many strategies do not yet have 20+ years of track record, and many come from first-time managers. Clearer evidence, standardised reporting and peer examples matter, but #PensionFunds also need to be genuinely open to allocating.

Julia Balandina Jaquier, Tara FO / Swiss Platform for Impact Investing (SPII) brought the #FamilyOffice and #NextGen lens: ambition is high, but execution still depends on better governance, stronger advisers and more institutional-quality impact solutions.

Adelina Toader, Kapnest, moderated the 2nd panel, and highlighted that investor demand is growing, but regulatory complexity, limited investable pipelines and the lack of large-scale impact wealth management capacity are slowing development:

Mona Huys, Mercer, underlined that investing in nature and food systems is essential for resilience and ecosystem health, but also makes economic sense as private markets opportunities continue to emerge.

Florence Kiss, Lombard Odier Group, stressed the need to mobilise capital to transform global food value chains and regenerate nature as part of building a #NetZero, nature-positive economy with resilient long-term value.

Tom Kagerer, Vlinder, reminded us that after decades of #NaturalCapital depletion, the next decades must be defined by #restoration and #conservation, with proven solutions ready to scale.

Nabil Marc ABDUL-MASSIH, INOKS Capital S.A., brought the #PrivateDebt and agri-food value-chain perspective: financing #inefficiencies in EU #FoodSystems remain materially underserved, and debt can be a powerful instrument for real economy impact.

For SIO, the conclusion is clear: Nature finance, sustainable food and agri, and #NBS are #investable, understandable and increasingly institutional. The task now is to strengthen LP #governance alignment, improve execution capacity and mobilise more capital into strategies that can deliver both positive impact and returns.

Our thanks to all speakers, guests and friends who joined us.

SIO was delighted to co-host our – full-house – Impact Gathering & Christmas Apero together with INOKS Capital S.A. last week in Zurich. The discussion focused on how alternativeinvestments, realassets and impact strategies are converging around sustainable food and agriculture, driven by foodsecurity, climate pressures and changing investor expectations.

Nicolas Laporte, mentioned that private debt is becoming a mainstream asset class, increasingly used as a proxy for fixed income in diversified portfolios. The universe of ESG and impact managers remains limited, requiring pragmatic allocation choices and selective arbitrage. Interest in ESG and impact strategies is steadily increasing, especially among younger private banking clients, where sustainability is becoming a baseline expectation.

Rosa Sangiorgio, mentioned that Switzerland faces a defining choice: to be remembered as the place that protected yesterday’s wealth, or as the place that helped design the financial system for tomorrow. Impact investing is not a niche; it is good risk management in a world where climate, health and social tensions are now priced.

Mirjam Garzon, stated that the impact investing community continues to grow fast each year, while methodological challenges around definitions and measurement remain. Sustainable food and agriculture stand out as one of the most important and widely supported themes across the global impact community.

Nabil Marc ABDUL-MASSIH, presented short-term, asset-backed food chain financing in developing economies, mentioning it usually carries lower risk than perceived when properly structured and monitored, while delivering tangible local impact including job creation and women empowerment. In Europe, a significant “missing middle” financing gap exists for agri-food SMEs, creating an attractive private debt opportunity. aligned with the EU’s food security agenda.

Yullie (Panagiota) Matsouka mentioned that impact investments increasingly deliver on investor expectations, often more consistently than traditional strategies. They are fundamentally real-economy investments and do not carry higher risk by default.

Kostis A. Tselenis highlighted clear macro trends: impact strategies are becoming a structural allocation in institutional portfolios, not a niche. Evergreen structures, particularly in private debt, are gaining momentum as investors seek income, resilience and real-asset exposure. The traditional narrative of impact versus returns is increasingly obsolete.

Thank you to all speakers and participants for a thoughtful, investor-driven discussion!

“…Investments totaling 50 million euros in Greek agri-food businesses – Which fund wants to finance Greek producers, what are its criteria and why the impact is critical?…

Among the investors who have placed capital in INOKS Capital is the Swiss Impact Office, a multi-family office and investment advisor that combines efficiency with impact.

“We work with families, institutions and private banks that want to invest in real sustainability projects, with profitability and measurable results,” explains Kostis Tselenis, managing partner of the Swiss Impact Office, which made its first investment in Greece a few years ago, in Βrite Solar, an agrophotovoltaic technology company that combines food and energy production.

“Our goal is to prove that impact investing is a new form of profitable investment, not charity. Zurich has evolved into a center for such investment strategies, and Greece has all the conditions to become the hub of southeastern Europe for sustainable investments,” emphasizes K. Tselenis…”

We will have the honour of joining Alexandra Mitsotaki at the World Human Forum’s 3rd Symposium for a New Eleusis, to explore how Impact Investing can align profit with purpose, mobilising capital for reforestation, regenerative agriculture, water security, and biodiversity protection.

We will reflect on the third wave of Nature Finance that is emerging: a shift in values from seeing nature as a resource to recognising it as a living system built on contributions, stewardship, and trust.

Join us at the Old Oil Mill Factory in Elefsina, Athens, on the 26th of September. More information
