2025 marked a step change for IONATE.
It was the year momentum of our $17M Series A turned into substance: doubling the team, advancing our technology, and deepening our engagement with customers, policymakers, and partners shaping the future of energy infrastructure.
It was also the year AI became an infrastructure problem. Systems built on an outdated grid began to strain. Across the sector, one reality came into focus: progress depends on power infrastructure that can manage power flows intelligently, efficiently, and at scale.
That context shaped everything we did this year.
Winter set the commercial direction
Following our raise, the focus became execution. We expanded our technical team to meet accelerating demand from industrial customers and data centres deploying Hybrid Intelligent Transformer, laying the foundations for delivering capacity at scale.
Conversations increasingly shifted to capacity, lead times, and how to integrate smarter transformers into live industrial and data-centre environments.
Those discussions played out across both sides of the Atlantic. In the US, we reconnected with the US energy ecosystem at DITRIBUTECH in Dallas, TX, focused on scaling power for AI, industry, and electrification. In Europe, at E-WorldEnergy & Water in Essen, we took the stage to discuss the next phase of scaling wind power.
At the same time, IONATE’s role in the energy and security landscape continued to sharpen. Our co-founder hosted NATO DIANA’s Defence and Security Days in Krakow, and we were featured in a joint Dealroom.co and NATO Innovation Fund deep-tech report, reinforcing our position at the intersection of energy resilience, security, and innovation.
To close the quarter, Luca visited Energy Minister Shanks at the UKDepartment for Energy Security & Net Zero, grounding policy discussions in operational realities.
As the cold started easing, our foundations were set: tech, capital, and credibility.

Spring and Summer created space to scale
As the team grew, we moved our HQ to London GreenCity. The new site gives us expandable lab and office space, proximity to a strong industrial and innovation ecosystem, and the operating environment needed for collaboration – a physical shift that mirrors our growth and maturity.
With that foundation in place, we stayed active in influential conversations.
In April, IONATE CGO Luca spoke at Energy Tech Summit in Bilbao on the next stage of power infrastructure, and was quoted by Business Insider on accelerating data centers power demand.
In May, Founder & CEO Matthew joined a fireside chat at the University of Cambridge, with IQ Capital’s Jordan Billiald, reflecting the best ideas in the intersection of research, capital, and execution.
June was about visibility and velocity. We took the stage at London TechWeek and The Next Web (TNW) in Amsterdam, and hosted a fireside with the latest NATO DIANA cohort in London.
In July, IONATE featured prominently in NetZero Insight’s H1 research andClimate Tech Webinar, analyzing the deep tech landscape in situ on the back of our success story.
By the end of summer, we had the physical capacity to scale, a growing team to execute, and a seat at influential tables across Europe and beyond.

Autumn took us around the globe
As the year progressed, conversations became more global and more concrete.
CEO Matthew took IONATE into Southeast Asia, speaking at SWITCH, and SingaporeEnergy Week, before joining forums in Kuala Lumpur and Bangkok. Across theregion, electrification is moving fast, and infrastructure decisions carry immediate commercial weight.
In parallel, CGO Luca travelled to North America. She opened the International Energy Agency's Energy Innovation Forum ahead of the G7 energy ministers meeting in Toronto, having joined the IEA's Technology and Innovation Advisory Board earlier this year. This was before heading back to Silicon Valley to speak at M-Lab Ignite xGreentown Labs and the Xtreme Tech Challenge AI Innovation Summit –conversations centred on scaling power infrastructure for AI-driven growth.
Closer to home, IONATE was named Most Fundable Company at BrownRudnick’s Clean Tech Showcase in London, participated at Sifted Summit on winning top engineering talent, and spoke about the importance of power infra innovation at InnoEnergy’s TBB in Lisbon. and the Cleantech Forum in Sitges. At last, conference season closed with Luca taking the Google stage at Slush in Helsinki.
Amid the travel, the team regrouped at our London HQ, joined by our Vienna software team for a week of building and ideation. To close the year in style,we launched a new website – new look, same core mission.
Bring on 2026
2025 wasn’t about one moment. It was about consistency: building, showingup and staying close to the industry’s heartbeat.
By the year’s end, IONATE was clearly positioned as an enabler of global infrastructure at scale, reshaping the possibilities across both the grid andthe big power users.
What comes next lays on the foundation we built this year. We think it will be good.
Stay tuned.
