J2 Ventures Closes $250M Brookhaven Fund for Dual-Use Innovation

J2 Ventures, a veteran-led venture firm, has announced the closure of its $250 million Brookhaven Fund. The fund has been oversubscribed and attracted prominent LPs such as JP Morgan, MetLife, Upsher Management, Alpha Leonis Partners, and the State Investment Council of New Mexico. Brookhaven Fund is one of the largest early-stage vehicles dedicated to dual-use technology, reflecting the growing momentum behind J2's approach. The fund aims to strengthen economic and national resilience by supporting founders in scaling innovation with commercial reach and impact.

J2 Ventures' Managing Partner, Alex Harstrick, emphasized the significance of collaboration between national necessity and private ingenuity, citing examples like Oracle, Cisco, and Pixar that originated from early collaborations with the public sector. The firm's cross-disciplinary perspective, spanning national security, science, finance, entrepreneurship, and public policy, allows it to evaluate technologies through both mission-critical and market-driven lenses. The new fund, Brookhaven, will focus on early-stage investments in companies developing critical technologies in health, infrastructure, and security.

J2 Ventures aims to empower founders with capital, insight, and access, ensuring that groundbreaking technologies reach scale, adoption, and global impact while preserving value for the founder. The firm also leverages its deep ties across defense and intelligence to help founders secure non-dilutive capital and navigate complex regulatory environments.

J2 Ventures' Brookhaven Fund marks its third consecutive oversubscribed fund, showcasing long-term confidence in its performance and purpose. J2 Ventures is a Boston-based venture capital firm that focuses on technologies advancing commercial markets and U.S. national security. Its portfolio companies have raised more than $1 billion in follow-on capital and secured significant non-dilutive government funding, aligning with the firm's mission to make innovation scalable and enduring.
