Fleetzero

Fleetzero is a Houston-based maritime technology company, founded in 2021 and led by U.S. Navy veterans and shipping-industry experts, building battery-electric energy and robotics systems to decarbonize ocean shipping at cost parity with fossil fuels. Its Leviathan modular marine energy storage system, 3.8 MWh marine battery containers, and 55 MWh battery barges provide propulsion power and mobile charging infrastructure for cargo vessels. Backed by Obvious Ventures, Fleetzero was added to the API Evangelist network as a portfolio-lead stub; it currently publishes no public developer, API, or documentation surface, so this profile carries company identity and infrastructure signals only.

Fleetzero is profiled on the APIs.io network. Tagged areas include Company, Maritime, Shipping, Batteries, and Energy Storage.
