§ Private Profile · Miami, FL, USA
Developer of full-stack renewable energy systems integrating solar and storage for 24/7 power for AI data centers.
Based in Miami, Florida, Exowatt develops modular renewable energy systems that integrate solar generation with low-cost storage to provide continuous, dispatchable power for energy-intensive applications. The company designs and manufactures its full-stack infrastructure directly within the United States, prioritizing scalability and unit economics over peak efficiency to deliver sustainable electricity. These hardware solutions primarily target artificial intelligence data centers, heavy industrial sites, and commercial facilities that require reliable, round-the-clock renewable power generation. To support rapid deployment and domestic manufacturing expansion, the enterprise has secured $140 million in total funding, including a $70 million Series A and a $50 million extension. This capitalization was backed by a syndicate of prominent institutional and angel investors featuring Sam Altman, Andreessen Horowitz, Felicis, Atomic, and Leonardo DiCaprio. Exowatt was founded in 2023 by Hannan Happi and Jack Abraham.
Exowatt has raised $175.0M across 4 funding rounds.

Exowatt is a technology company that designs and manufactures modular, full-stack renewable energy systems, primarily focused on delivering clean, dispatchable solar power. Their flagship product, the Exowatt P3 system, captures solar energy, stores it as heat using a proprietary high-temperature sensible heat battery for long-duration energy storage (LDES), and converts it into electricity on demand through a heat engine. This modular system fits within a 40-foot shipping container, enabling rapid deployment and scalable energy solutions. Exowatt primarily serves energy-intensive industries such as data centers, especially those supporting artificial intelligence (AI) infrastructure, addressing the critical need for reliable, low-cost, and sustainable power. Their technology aims to solve the intermittency problem of solar energy by providing 24/7 dispatchable renewable power, which is crucial for the growing AI and digital economy[1][3][4].
Founded by Hannan Parvizian, Exowatt emerged from the recognition that while solar and wind energy have advanced sustainability, their intermittent nature limits reliability. The company was created to build the energy infrastructure for what they call "World 3.0"—a future powered by abundant, clean, and continuous energy to fuel AI and innovation globally. The idea was to combine advanced solar-thermal technology with AI-powered management software to create a scalable, modular energy system that can be rapidly deployed and operated anywhere. Early traction includes significant investment from prominent figures such as OpenAI’s CEO and venture capital firms, underscoring the strategic importance of their technology in powering AI data centers and other critical infrastructure[1][2][6].
Exowatt is positioned at the intersection of two major trends: the rapid expansion of AI infrastructure and the urgent global transition to renewable energy. As AI workloads grow exponentially, data centers require vast amounts of reliable, low-carbon power. Exowatt’s dispatchable solar technology addresses the critical challenge of renewable energy intermittency, enabling continuous clean power that can scale with AI demands. This timing is crucial as industries seek to decarbonize while maintaining operational resilience. By providing modular, scalable, and cost-effective energy solutions, Exowatt influences the broader ecosystem by enabling sustainable growth of digital infrastructure and advancing energy independence in the U.S.[2][4][5][6].
Looking ahead, Exowatt aims to scale production significantly, with ambitions to reach one million units to meet the surging demand for clean, dispatchable energy in AI data centers and other industrial applications. The company’s future trajectory will be shaped by trends such as the increasing electrification of industries, AI-driven energy management, and global decarbonization efforts. As energy demands grow and sustainability becomes a non-negotiable priority, Exowatt’s modular, AI-optimized solar-thermal systems are well-positioned to become a backbone of the new energy economy. Their continued innovation and scaling could redefine how industries power themselves sustainably, accelerating the transition to a low-carbon future while supporting the digital revolution[6][2][4].
