    "long_description": "REGENT is building a new mode of transportation that will redefine regional mobility by 2026. Their first product, the seaglider, is an all-electric, hydrofoiling flying-boat that operates within a wingspan of the water's surface.  By flying low on a cushion of air, seagliders unlock the ability to fly twice as far as an electric aircraft, while being regulated by maritime authorities enabling market entry for a fraction of the cost.\r\n \r\nREGENT has de-risked seaglider technology with a ¼-scale flying demonstration vehicle. By this summer, REGENT will fly humans on the 15,000 lb (7000kg) first full-scale prototype seaglider, which will be the largest electric-flying machine in history.\r\n\r\nBy late 2026, REGENT’s customers - airlines and ferry companies – will begin commercial seaglider service on the 12-seat initial product.  A 100 passenger version, already with firm orders, will follow several years later.\r\n\r\nIn just four years, REGENT has accumulated >$10B in pre-orders (including firm deposits) from airlines and ferry companies around the world.  Currently a team of 100, REGENT is led by MIT-trained, ex-Boeing engineers Billy Thalheimer and Mike Klinker.  REGENT has raised over $100M to date from the likes of Founders Fund, Japan Airlines, Hawaiian Airlines and Lockheed Martin, and is on contract with the US Marine Corps.",

        "body": "### **TLDR:**\n\nHey everyone! We’re [**John**](https://www.linkedin.com/in/john-huddleston-3584121b7/) (engineer and unmanned systems expert) and [**Dante**](https://www.linkedin.com/in/dante-vaisbort/) (repeat defense founder). [**Albacore Inc.**](https://www.albacore.inc/) is building the next generation of unmanned underwater vehicles (UUVs) to prevent maritime invasions. Our first product is **Ghostfin:** a 6-foot-long autonomous underwater vehicle that can patrol over 1,000 nautical miles undetected and massively damage hostile watercraft.\n\n[**https://www.youtube.com/watch?v=UQ6SYgIsDQs**](https://www.youtube.com/watch?v=UQ6SYgIsDQs)\n\n### [**🏴‍☠️**](https://emojipedia.org/pirate-flag) The Problem: America doesn’t have any long-range underwater strike weapons.\n\nIn the case of an Indo-Pacific conflict, our military’s existing suite of autonomous underwater vehicles is woefully unprepared. Today’s unmanned underwater vehicles are short-range, expensive, and overly mission-specific. Unlike the Ukrainians or even the Houthis, America doesn’t have underwater vehicles built for attack missions in service.\n\n### **🚀 Our Solution: Low-cost autonomous underwater vehicles that can travel 10x further.**\n\nRange is the key constraint in massive bodies of water like the Pacific Ocean. The Albacore team has spent years working on power technology and manufacturing for unmanned systems, and can build Ghostfin far more efficiently than anything on the market today by using a combination of highly scalable in-house-designed and off-the-shelf components.\n\n![uploaded image](/media/?type=post&id=92587&key=user_uploads/2629924/1f9c199a-487c-4de0-848e-94ae31db9ba6)\n\n### 👥 **Our Team:**\n\n**John Huddleston, Co-Founder:** John is a mechanical engineer who spent 3 years at the Boston Consulting Group advising government agencies and Fortune 500 companies in the defense industrial base. He worked on >$9b in unmanned systems manufacturing and procurement efforts alongside senior military leadership.\n\n**Dante Vaisbort, Co-Founder:** Dante is a second-time founder in defense, who has won and led more than >$10m in DoD contract efforts for his first company, Haylon Technologies, which builds power technology for autonomous systems and is still active.\n\nWe also have an incredible engineering team hailing from Lockheed Martin, Johnson & Johnson etc. who have won underwater vehicle competitions and have a combined 20 years experience on space flight technology, autonomous vehicle AI, medical robotics, and robosubs.\n\n![uploaded image](/media/?type=post&id=92587&key=user_uploads/2629924/550044dc-1333-486f-8877-384a1270c501)\n\n### **😇 Our Ask:**\n\nPlease reach out to us if you can help us deliver solutions to the Navy, Special Operations Forces, intelligence community, or allied foreign militaries. If you know any commercial entities who may want this, that’s great too!\n\nStay tuned for us to blow stuff up in the next one. In the meantime, drop us a line at [**founders@albacore.inc**](mailto:founders@albacore.inc)",
