Sustainable impact requires sustainable energy. As co-founder of Seabound - onboard carbon capture for shipping - Alisha Fredriksson shares the advice that changed the way she thinks as a founder. Learn what fuels her for the long road ahead.
Seabound achieves another milestone! Today, Seabound and STAX Engineering co-hosted a Carbon Capture Showcase in the Port of Long Beach to demonstrate our integrated zero emissions solution for vessels at berth. We boarded a catamaran together with 60+ industry leaders, regulators, and investors, setting sail on an immersive journey through the port, which culminated in a live demonstration of our carbon capture system at work. Together, we witnessed the integrated solution in action, servicing a Wallenius Wilhelmsen roll-on roll-off (RoRo) vessel. First, the STAX system connected to the ship’s exhaust pipes to channel the exhaust gas through a purification system. The harmful criteria pollutants including NOx, PM, DPM, and ROG, were removed before the exhaust gas passed through the Seabound Demonstration Unit. Then, using our lime-based technology, we trapped the CO2 emissions and transformed them into limestone. As guests witnessed live on our measurement dashboard, we achieved a 94% CO₂ capture rate, successfully demonstrating the world’s first CO2 capture system in port. This milestone arrives at a critical time. Just last week, the International Maritime Organization (IMO) agreed to a first-ever global carbon price that could force ships to cut their carbon intensity by 65% by 2040, underscoring the urgency for scalable decarbonization solutions. Read more about today’s landmark demonstration in the full press release linked in the comments.

Seabound is thrilled to announce our collaboration with Associated British Ports (ABP) and STAX Engineering to explore at-berth carbon capture solutions at the Port of Southampton. This collaboration, unveiled during the EVA Southampton Innovation Exchange at the Maritime UK Solent Coastal Powerhouse Summit, aims to reduce emissions from vessels while docked. STAX Engineering filters criteria pollutants from the exhaust gases, which are then routed to Seabound’s system where we remove carbon and sulphur emissions. This means cleaner air at ports and significantly less CO₂ and sulphur dioxide released into the atmosphere. ABP's sustainability strategy underscores their dedication to green shipping, and we’re proud to help them achieve their ambitious targets. This joint effort marks a significant step toward cleaner maritime operations. Stay tuned!
ABP News Release: Port of Southampton welcomes hundreds of innovators to accelerate maritime decarbonisation🌍 The EVA Southampton Innovation Exchange, took place on the first day of the Maritime UK Solent Coastal Maritime Summit. Alastair Welch, ABP’s Regional Director for Southampton, said: “Today, we’ve been able to demonstrate Southampton’s place at the heart of maritime decarbonisation in the UK. Southampton has been a leader in UK port sustainability through being the first port to deploy shorepower at scale and by publishing a comprehensive air quality strategy. “At ABP, we are committed to leading positive change when it comes to maritime decarbonisation both through our sustainability strategy ‘Ready for Tomorrow’ and initiatives like EVA. We are developing the infrastructure to support green shipping and working with our partners to turn ambition into reality.” The themes of innovation and sustainability were also reflected in Maritime Minister Mike Kane’s keynote speech at the Summit, who said: “We have just announced our plan for shipping to become net zero by 2050, and it’s great to see ports like ABP embrace these ambitions by going even further and faster to decarbonise.” “It’s a pleasure to join the Coastal Powerhouse Summit and come together with leading innovators across the industry so we can drive forward the progress needed to clean up maritime, establish the UK as a clean energy superpower and drive economic growth across the country.” The EVA Southampton Innovation Exchange provided the stage for ABP to announce its intention to work with green maritime innovators Seabound and STAX Engineering to explore opportunities to capture at-berth emissions while vessels are in port. ABP is currently engaging with key shipping customers looking at technical and economic feasibility with a view to deploying the technology in early 2026. Max Harris, ABP’s Group Head of Strategy & Sustainability, who leads the EVA programme, commented: “I am delighted to announce that as part of ABP’s broader strategic ambitions, we are excited to be working with UK carbon capture startup Seabound and California emissions capture service provider STAX Engineering, who are integrating their solutions to minimise both air pollutants and greenhouse gas emissions – helping to make shipping and ports more sustainable.” 👉 Access the full press release here: https://lnkd.in/e9fHsT3f Thank you to all who contributed to and attended this great event! #Innovation / Plug and Play UK / #ABPventures / Lex Hanham / Ralph Windeatt / Department for Transport (DfT), United Kingdom / #CoastalPowerhouseConference / #Decarbonisation / #Maritime / Mary Carmen Barrios / Charles Haskell / Kay Lemcke / Peter Livey / Tristan Smith / XFuel / Armada Technologies / PuriFire Energy) / GT Wings
Happy 20th, YC! 🥳 Thank you for shaping the startup world and for bringing Seabound along for the ride—grateful to be part of your history! Check out Digital Frontier's deep dive on Y Combinator's legacy, featuring Seabound—big thanks to Tasmin Lockwood for including us in the piece!
🚀 Y Combinator turns 20 🥳 Two decades ago, a bold experiment changed startups forever. A small group of founders joined an accelerator that offered $6,000 per person, mentorship, and an intense sprint to build fast. That small experiment grew into Y Combinator, the most influential startup accelerator in the world. From an eight-startup first batch, including Reddit, Inc. to 4,000+ companies worth over $600B, YC’s fingerprints are all over the tech world. Some of the biggest names in startups got their start here: 🏠 Airbnb 💳 Stripe 📦 Dropbox 💰 Coinbase 🏃♀️ DoorDash 🛒 Instacart But YC didn’t just fund startups, it rewrote the playbook. It pioneered the modern accelerator model, introduced the SAFE note (now a startup funding standard), and turned Demo Day into a high-stakes investor feeding frenzy. Its influence goes beyond the unicorns. A new wave of YC founders is tackling some of the biggest challenges in AI, fintech, and climate tech: 🌍 Alisha Fredriksson → decarbonising shipping 💳 Philip Kelvin → transforming B2B payments 📡 James He → AI-powered forecasting 🛠 Adam Siegel → crowdsourced predictions The way YC operates has evolved over time. Early batches meant hands-on mentorship. Now, with 300+ startups per cohort, founders tap into network effects, learning as much from each other as from mentors. And while its scale has grown, being backed by YC remains one of the strongest credibility signals a startup can have. Many alumni have gone on to reshape the tech world, not just as founders, but as investors and ecosystem builders: 🎤 Ian Hogarth (Songkick) shaping the music industry 📊 Amplitude redefining product analytics 🚴 Stanley Tang (DoorDash) changing food delivery 💰 Don Muir (Arc) revolutionising startup financing So what’s next? Under Garry Tan, YC is betting big on AI, deep tech, and global expansion. The next Stripe, OpenAI, or DoorDash? It’s probably in a YC batch right now.

Seabound x STAX: Partnering for a Cleaner Future in Shipping 🚢 This week, we’re excited to announce our partnership with STAX Engineering to accelerate maritime decarbonization and create cleaner air in ports. STAX is a California-based leader in maritime emissions capture and control. Its flexible, barge-based system attaches to any type of ship exhaust stack while in port without requiring any modifications to the ship. The STAX system filters out 99% of PM and 95% of NOx—criteria pollutants that harm local environments and the health of surrounding communities—releasing a purified gas. Seabound is a London-based pioneer in modular carbon capture technology that captures both CO2 and sulphur emissions onboard ships - harmful greenhouse gases regulated by the International Maritime Organization. We’re currently undergoing trials in the Ports of LA and Long Beach to integrate and test Seabound’s carbon capture system on a STAX capture and control barge. By combining our two technologies, we can capture both criteria pollutants and greenhouse gas emissions from ships while they’re in port, thereby creating cleaner air for local communities and decarbonizing ships while at-berth.
