Seabound vs IBM
Side-by-side comparison of AI visibility scores, market position, and capabilities
Maritime carbon capture startup using calcium oxide chemistry to capture ship exhaust CO2 as solid calcium carbonate for offloading; onboard retrofit technology for shipping decarbonization.
About
Seabound is a maritime carbon capture technology company developing systems that capture CO2 from ship exhaust directly onboard vessels, storing it as calcium carbonate for offloading at port — enabling the shipping industry to reduce emissions without switching to alternative fuels. Founded in 2021 and headquartered in London, Seabound has raised approximately $4.8 million in seed funding and is developing a post-combustion carbon capture approach that can retrofit onto existing ships without requiring engine replacements or fuel changes.\n\nSeabound's system works by diverting flue gas from a ship's engine exhaust through a reaction chamber containing calcium oxide (quicklime), which reacts with CO2 to form calcium carbonate — a solid, stable material that can be offloaded at port and sold as a feedstock for construction materials or industrial processes. This chemistry eliminates the need for compressed CO2 storage or cryogenic liquefaction, which are significant technical and safety challenges for onboard carbon capture. The calcium oxide can be regenerated at port facilities.\n\nIn 2025, Seabound operates in the emerging maritime decarbonization market where the International Maritime Organization (IMO) has established targets to cut shipping emissions 50% by 2050. Maritime shipping is responsible for approximately 2.5% of global CO2 emissions, and the sector faces growing regulatory pressure (EU ETS carbon pricing extending to shipping from 2024). Seabound competes with other maritime carbon capture startups and against alternative decarbonization approaches (ammonia fuel, hydrogen, LNG). The 2025 strategy focuses on completing pilot installations on commercial vessels, demonstrating the techno-economic case for operators, and partnering with port infrastructure providers for calcium oxide supply and calcium carbonate offtake.
Armonk NY hybrid cloud and enterprise AI (NYSE: IBM) at $62.8B revenue; $6B+ generative AI bookings, record $12.7B free cash flow 2024, DataStax acquisition for watsonx vector database competing with Microsoft Azure for enterprise AI.
About
International Business Machines Corporation (IBM) is an Armonk, New York-based global technology and consulting company — publicly traded on the New York Stock Exchange (NYSE: IBM) as an S&P 500 component — providing hybrid cloud infrastructure, artificial intelligence software, and enterprise IT consulting through approximately 270,300 employees in 170 countries with $62.8 billion in annual revenue. Founded on June 16, 1911, as Computing-Tabulating-Recording Company through a merger orchestrated by financier Charles Ranlett Flint, renamed IBM in 1924 under Thomas Watson Sr., IBM has undergone multiple strategic transformations over its 110+ year history: building the System/360 mainframe platform (1964), launching the IBM PC (1981), selling the PC division to Lenovo (2005, $1.75B), and completing the $34 billion Red Hat acquisition (2019) that repositioned IBM as a hybrid cloud platform company. CEO Arvind Krishna (appointed April 2020) has focused IBM's strategy on three areas: hybrid cloud (powered by Red Hat OpenShift, the enterprise Kubernetes platform), AI (the watsonx platform for enterprise AI model development and deployment), and enterprise consulting. Under Krishna, IBM recorded $12.7 billion in free cash flow in 2024 (a company record), surpassed $6 billion in generative AI bookings since June 2023, and saw the stock price double — trading at all-time highs through 2024-2025. IBM announced the DataStax acquisition in 2025 to deepen watsonx's data layer with AstraDB (vector database for AI applications), DataStax Enterprise (Apache Cassandra), and Langflow (low-code AI agent development).
