About Exowatt
Company Overview
Name
Exowatt, a privately held company
HeadquartersMiami, United States
Founded2023
SizeApproximately 90 employees in recent years (source: tracxn.com)
What They Do
Exowatt develops modular, transportable power systems specifically designed to meet the demanding energy needs of AI data centers and other high-load customers. Their flagship product, the Exowatt P3, captures solar energy and stores it as high-temperature heat, which is then converted into dispatchable electricity on demand, enabling 24-hour renewable power availability (source: exowatt.com). This technology aims to reduce reliance on conventional grid power by providing a reliable, renewable energy source tailored for AI infrastructure, commercial, government, and off-grid applications (source: exowatt.com). The company emphasizes modularity and dispatchability, targeting frontier land data centers that require rapid access to large amounts of power, positioning itself as a critical enabler for the future of AI and energy-intensive industries (source: wikipedia.org).
Projects & Track Record
As a young company, Exowatt's project portfolio is in the early stages, focusing primarily on deployment planning rather than completed large-scale projects (source: wikipedia.org). The company announced in April 2025 that its $70 million Series A funding would support commercial deployments starting that year (source: exowatt.com). While no public list of completed projects with specific capacities or commissioning dates is available, Exowatt’s focus remains on AI-scale data centers and other large-load customers (source: exowatt.com). The company has attracted significant backing from prominent venture and strategic investors including a16z, Atomic, Felicis, Sam Altman, HSBC Innovation Banking, and others, underscoring confidence in its technology and market potential (source: refreshmiami.com).
Recent Developments
In April 2025, Exowatt closed a $70 million Series A funding round, split evenly between $35 million in equity and $35 million in debt, bringing total funding to $90 million at that time (source: exowatt.com). This round was led by Felicis and included HSBC Innovation Banking among other lending partners, with prior seed investments from a16z, Atomic, and Sam Altman (source: refreshmiami.com). Coverage in 2025 highlighted Exowatt’s emergence from stealth mode, its dedicated focus on AI data-center power solutions, and rapid team growth from approximately 25 employees toward a larger engineering organization based in Miami (source: refreshmiami.com). By 2026, the company had expanded to roughly 90 employees and secured total funding of $105 million across five rounds (source: tracxn.com).
Working There
Exowatt hires across a range of roles focused on hardware engineering, product development, operations, manufacturing, and deployment support, reflecting its identity as a deep-tech hardware startup rather than a software-only company (source: refreshmiami.com). The company’s growth strategy centers on leveraging Miami-based talent, with the primary office located in Miami, Florida (source: exowatt.com). Public materials and case studies highlight a focus on systems development, product storytelling, and deployment-oriented work, indicating a collaborative environment for engineers and startup builders (source: wheelhouse.io). While detailed benefits and role-specific hiring information are not publicly documented, the company’s visible hiring profile suggests opportunities in mechanical and electrical engineering, product management, and operational roles (source: exowatt.com).
