    European Defence Founders: DTCP’s 500M Fund Is Open

    Europe needs more defence capital. But investing in defence requires more than money: it demands specialist knowledge, patience, strong industry relationships and an understanding of how the sector actually works. In this episode, Colin Brown sits down with Joel-Oskar from DTCP to explore the investment opportunity in European defence, security and resilience, and what it takes to build the next generation of European defence technology companies. DTCP has launched a dedicated defence fund with approximately 500 million in capital, focused on backing European defence and security businesses. With a focus on growth-stage companies, the fund aims to help promising businesses scale their products, manufacturing capabilities and commercial reach. Joel-Oskar shares his journey from Finland to London, his experience investing in technology and cybersecurity, and why he believes now is a pivotal moment for European defence investment. IN THIS EPISODE Inside DTCP’s defence fund Discover the fund’s investment thesis, its growth-stage focus, and the kinds of companies it wants to back. Kraken Technologies and autonomous maritime systems Why maritime security, unmanned surface vessels and the protection of critical infrastructure represent important opportunities for European defence. Six Robotics and drone swarming Learn how autonomy and software can coordinate multiple drones, and why open technology ecosystems could shape the future of defence. What defence founders need from investors Why specialist investors matter, how long government procurement cycles differ from traditional software sales, and why the right relationships can be as important as capital. Closing Europe’s defence funding gap Why Europe needs more dedicated defence investment, greater participation from private capital and pension funds, and more funding to help companies manufacture and scale. KEY TAKEAWAY FOR FOUNDERS Not all venture capital is created equal. When choosing an investor, founders should look beyond the size of the cheque. Does the fund have the right people, experience, relationships and understanding of defence procurement? Can it help the business navigate strategic partnerships and scale across Europe? For companies with proven products, customer traction and a path to growth, finding the right investment partner can make a significant difference.

    Why Forests Need Drones | Air Forestry

    Today, thinning a forest means sending two 20-ton machines in to remove trees that weigh about 80kg on average. The trails they need clear-cut roughly 20% of the forest, just for access. Air Forestry does it from the air instead. A six-metre, six-armed drone selects a tree, grabs it from the top, strips the branches using gravity, cuts the trunk with an electric chainsaw, and lifts the whole tree out to the roadside. It’s the same end product the industry already pays for, without a single track through the forest. Co-founder and CEO Caroline Walerud has spent 15 years in startups and deep tech investing. She sold bread door to door as a teenager, studied natural sciences at Cambridge, and founded Volumental, which has now scanned more than 60 million feet. She then invested in deep tech through her family’s office before jumping back in as an operator. In this episode, Colin Brown and Caroline cover: - What selling bread door to door teaches a founder - Volumental: starting with a technology instead of a problem, and what that cost - Investor vs operator: the filter of “would I work with this team two days a week for 15 years?” - Forestry 101: why commercial thinning matters for forest health, carbon and wildfire risk - The world’s first air harvest - How two operators supervising 6–12 drones could deliver a huge productivity increase - Why forestry is a regulatory sweet spot for autonomy - Building a vertically integrated drone, tool and software stack in Uppsala Chapters 00:00 Intro 00:55 From door-to-door bread to Cambridge 02:13 Lessons from selling door to door 03:25 Volumental and 60 million feet 08:34 From investor to founder 12:01 The first meeting: harvesting a tree from above 15:03 Forestry 101: why thinning matters 19:58 20-ton machines vs 80kg trees 22:11 The world’s first air harvest 26:32 Huge productivity increase 29:04 Inside the drone 32:03 The team 34:49 Customers and pilots 37:16 Funding, grants and the regulatory sweet spot 41:24 Who should lead the round 42:58 Wrap-up 🔗 Air Forestry links: https://airforestry.com/ https://www.linkedin.com/in/cwalerud/ https://www.linkedin.com/company/airforestry/home/ #AirForestry #Forestry #Drones #Autonomy #ClimateTech #DeepTech #Sweden #Podcast

    Betting on Space, Robotics, Compute | OTB

    Marcin Hejka grew up in Gdańsk’s old town and went to a high school across the street from the shipyard where Solidarity was born. During strikes, his school sat inside the police cordon. At 20 he was helping write Poland’s foreign investment strategy. At 24 he sat on the board of a listed Polish bank. He then spent 18 years at Intel Capital. He joined in 1999 to open Central and Eastern Europe, when Polish internet penetration was around 1-2% and all dial-up, and finished as global IC member responsible for every international market except China. He personally led 36 investments, five of which became unicorns. Central and Eastern Europe turned out to be Intel Capital’s best-performing region in the world. Then he took UiPath to the investment committee twice, at seed and at Series A, and was turned down both times. That was his signal to leave. In 2017 he co-founded OTB Ventures as a deep tech fund when everyone else in the region was backing SaaS and marketplaces. OTB focuses on space, physical AI, and AI and novel computing, and ICEYE was its fourth investment. In this episode, Colin Brown and Marcin Hejka cover: - Growing up at the epicentre of Poland’s fight against communism - Intel Capital in its founder-led prime under Andy Grove - Why corporate VC drifts from strategy to tactics - The UiPath miss, and what it taught him - Why OTB picked three deep tech verticals instead of one - How sovereignty turned deep tech from a niche into the mainstream - OTB’s model: €1–10M first tickets, 8–15% stakes, a board seat and 50% reserves Chapters 00:00 Intro 01:19 Growing up in Gdańsk next to the shipyard 04:55 The last student strike and a government job at 20 08:57 A priest, a confessional and Poland’s first passports 11:46 Investment banking, Soros and a bank board at 24 14:31 Joining Intel Capital in 1999 17:19 Intel in its founder-led prime 20:46 CEE becomes Intel Capital’s best region 22:33 36 investments, five unicorns 25:22 Why leave Intel? 33:25 Saying no to UiPath, twice 36:16 Founding OTB in 2017 41:22 Sovereignty makes deep tech mainstream 48:06 OTB today: stage, tickets and ownership 54:42 What Marcin is most proud of 56:55 Wrap-up 🔗 OTB Ventures: https://otb.vc/ #DeepTech #VentureCapital #Poland #SpaceTech #Europe #Sovereignty #Podcast

    The Arctic Is Heating Up: Why Polarion Capital Is Betting on the High North

    There are around 4,600 drone companies in Western Europe. Polarion Capital doesn’t plan to back any of them.Instead, Polarion is building a specialist growth fund for the High North. It invests in Nordic defence and dual-use companies that have already won their first contract, and helps them win contracts two, three, four and five across NATO.GP Thomas Falck started his career on a Norwegian submarine. He was a founding partner at Verdane, CFO of Cognite, and chair of Norway’s state-owned VC. Now he’s raising a $120–150M first fund for 15 companies, backed by an advisory board of people who have worked inside the classified rooms of the Alliance.In this episode, Colin Brown and Thomas cover:- Why venture capital fits what armed forces need right now- Why the Arctic is becoming a global security hotspot, and why kit that works there tends to work everywhere- The coming drone consolidation, and why drone countermeasures are the bigger opportunity- Investing after the first contract: no moonshots, but not a buyout either- Fund size, ticket sizes and a focus on Norway, Sweden, Denmark and Finland- Deep tech meets deep trust: why this sector needs specialists, not tourists- Building an ecosystem through an invitation-only dual-use conferenceChapters00:00 Intro00:47 Why venture capital fits defence05:48 Are procurement cycles really changing?07:09 Why the Nordics and the Arctic are underserved09:51 4,600 drone companies and the coming consolidation12:27 Investing after the first contract14:51 Moonshots vs safe bets18:51 The Arctic thesis24:40 Fund size, tickets and geography28:45 The team33:21 The advisory board and classified innovation36:23 Deep tech meets deep trust38:10 Why specialists win in defence46:23 Sourcing: top-down and bottom-up51:25 The dual-use conference55:18 Wrap-up🔗 Polarion Capital: https://polarion.capital/#DefenceTech #VentureCapital #Arctic #Nordics #NATO #DualUse #Podcast

    Win the War, Defend Europe: Ragnar on Building Darkstar

    Darkstar is named after a 1970s science fiction film in which a crew has to talk a bomb out of exploding. Ragnar and his partners took a different lesson from it: Europe needs many small, smart ships to take out the threats it faces.Legally, Darkstar is a €25M pre-seed and seed defence fund that can invest in lethal technology. In practice it works like an ecosystem and a defence agency. It runs bootcamps in Ukraine, signs cooperation agreements with the Estonian Army’s Transformation Command, and its four GPs act as co-founders to the companies they back. Nine investments in, it’s halfway through its first fund.In this episode, Colin Brown and Ragnar talk about:🔹 Why Darkstar invests in lethal technology, not just dual use🔹 Why every defence product needs testing in Ukraine🔹 Farsight Vision: AI on real combat video and the automated kill chain🔹 A team that spent 16 months rebuilding its product when GPS stopped working🔹 Stratis: an Icelandic data platform born on a 30-hour drive to Kyiv🔹 The test every investment has to pass: “Would I join this company as a co-founder?”🔹 Plans for fund two, and why defence needs more capital at every stage🔹 The free Darkstar bootcamp in Ukraine, and who should apply🔹 Why Eric Schmidt deserves a shout-outChapters00:00 Why Darkstar?

    Arbit: The Danish Company Making Data Move Only One Way

    The French army asked the same question three times before they would sit down: “Are you certified EAL7+ by BSI in Germany?” Arbit is one of only two companies in the world holding Common Criteria EAL7+, the highest security certification available. At that level, it isn’t enough to claim your product works. You have to formally prove it, along with your supply chain, your production, your transport and your company culture. The first time took Arbit around 3,000 hours. Arbit builds data diodes and cross-domain solutions for armed forces, police, intelligence services and governments. It turns data into light and sends it in one direction only, and it can prove that nothing comes back. Colin Brown and Rik Ferguson sit down with Kasper Gubi of Arbit to talk about: - What EAL7+ certification actually takes, and why so few companies get there - Why one-way data transfer is different from encryption - How the customer base moved from intelligence services to the NATO battlefield - Insider threats, release portals and getting rid of USB sticks - Armoured vehicles running up to seven networks of different classifications - The F-35 integration question every European customer asked - Twenty years bootstrapped, 10x growth in six years, and a partnership with Leonardo - NATO data-centric security: prepare to share, but control what you share Chapters 00:00 Intro 01:40 EAL7+: one of two companies in the world 04:11 What EAL7+ actually takes 07:09 What a data diode does 08:35 Why this isn’t encryption 11:03 From intelligence services to the NATO battlefield 14:50 Civil applications and the cloud 15:31 Physical security: inside a client facility 18:34 Insider threats and release portals 21:18 Perfect vs good enough, and RAM prices 24:07 The elevator pitch 25:47 FedRAMP and the US question 28:05 Arbit’s history: 20 years bootstrapped 31:39 Scaling with open APIs 34:57 The F-35 integration question 38:16 NATO firebreaks: prepare to share, control what you share 40:31 Wrap-up #Cybersecurity #Defence #NATO #DataDiode #CrossDomain #Denmark #Podcast

    BAE Systems: The Company Britain Couldn’t Afford to Lose

    There was no garage, no single founder, and definitely no master plan. BAE Systems is what survived when dozens of British companies went through a century of wars, cancellations, nationalisation, privatisation and near-bankruptcy. Hawker, Vickers, Avro, de Havilland, English Electric, Marconi and Royal Ordnance were all absorbed. Almost all of their names have disappeared. One company remains. In 2025, BAE Systems generated £30.7bn in sales and £3.3bn in underlying EBIT. It ended the year with an £83.6bn order backlog and over 111,000 employees. It builds nuclear submarines, warships, combat aircraft, armoured vehicles, missiles, radar and electronic warfare systems. Its largest market isn't the UK. It's the United States. In our longest episode yet, Colin Brown and Martti Wallin tell the story in five acts: - How the Battle of Britain was won by an industrial system, not just "the few" - Freddie Page, the chauffeur's son who built the Canberra and the Lightning at Warton - The cancelled TSR-2, and why Britain had to learn to build aircraft with Germany, Italy and France- Nationalisation in 1977, privatisation in 1981, and the record £1.2bn loss that nearly ended it all - The Marconi deal that created BAE Systems, and why it chose America over a European merger - Selective sovereignty: what a nation must own, and what it can share with allies - What Europe should do next with its defence industry Chapters 00:00 Intro: what does "BAE Systems" actually mean? 09:44 Act 1: Britain at its zenith, Sopwith, Hawker and the Battle of Britain 01:02:23 Act 2: Peace, Warton and the Canberra, the Lightning and the TSR-2 01:52:56 Act 3: Britain learns to share: Jaguar, Tornado and British Aerospace 02:45:34 Act 4: Saudi Arabia, the end of the Cold War, near-collapse and the Marconi deal 03:25:09 Act 5: BAE Systems is born: Astute, America and selective sovereignty 04:06:22 Analysis: what France, Germany, Italy and Sweden did differently 04:29:34 Quintessence 04:33:20 Thank you and next episode: Red Bull Category Leaders tells the stories of European companies that are best in the world in their category.
