Fleetzero builds a fleet of electric cargo ships powered by a proprietary Marine Battery System to move goods in a cleaner way. They focus on smaller vessels built in domestic shipyards and designed to operate in regulated markets, enabling access to ports larger ships miss. The ships can operate autonomously, reducing crew and maintenance costs while allowing rapid battery upgrades as tech improves. The goal is to provide affordable, low-emission shipping without a green premium, transforming logistics toward sustainable, closer-to-market delivery.

↓ -5%Fleetzero, a marine technology company building hybrid and electric propulsion systems for ships, has raised $43 million in Series A funding led by Obvious Ventures. Maersk Growth and 8090 Industries joined as new investors, alongside existing backers including Breakthrough Energy Ventures and Y Combinator. The Houston-based startup will use the capital to expand manufacturing of its Leviathan propulsion system, which can be retrofitted onto existing vessels or installed in new ships. The company has opened a new manufacturing and R&D facility with initial capacity of 300 MWh per year, planning to scale to three GWh annually over five years. Fleetzero's system aims to reduce total ownership costs through maintenance and fuel savings whilst enabling marine autonomy. The company positions electrification as an opportunity to revitalise US shipbuilding.
Fleetzero, a developer and manufacturer of modular propulsion platforms for hybrid and electric ships, has selected Glosten, a Seattle-based naval architecture and marine engineering firm, to design what is expected to be the world's longest-range hybrid electric vessel.
Cost-effectively decarbonizing the shipping industry
Fleetzero is working to develop marine battery systems that offer higher density, low cost, and a high level of safety.
Birmingham, AL – According to filings with the U.S. Securities and Exchange Commission, Fleetzero is raising $16,463,983.00 in new funding. Sources indicate as part of senior management President and Chief Executive Officer, Steven Henderson played a key role in securing the recent investment and it will aid in aggressively expanding the company, as well as broaden and accelerate product development.
