Fusion energy has long been called the “holy grail” of clean power because in theory it’s cheap, abundant, clean, and safe. Yet despite 100+ years of scientific research and billions in investment, the profound engineering challenges associated with fusion-based power are far from settled.
Join us for a fireside chat with Sir Steven Cowley, Director of the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL).

Cowley is widely considered one of the most influential fusion scientists, having spent decades at the forefront of plasma physics, which is the technological key to containing fusion reactions for power generation. In his role at PPPL and prior to that as CEO of the UK Atomic Energy Authority, Dr. Cowley has shaped not only the science of plasma, but also the engineering strategies and global policy discussions around fusion power. For his contributions to science, he was appointed a Knight Commander of the Order of the British Empire (KBE).

SOSV portfolio company NOC Energy recently spoke with TechCrunch following its $2.7 million Seed funding led by 360 Capital, with participation from SOSV and Desai VC. NOC Energy is tackling one of the “hardest-to-abate” sectors: heavy industry. While industries like cement and glass typically rely on fossil fuels to reach temperatures of 1,500°C, NOC has developed an induction-based, high-temp electric […]

At our latest SOSV Deep Tech Live, we sat down with Carlos Araque, the CEO and founder of Quaise Energy, to discuss energy’s biggest challenge. But first, to understand Quaise, you have to understand the math of energy. Today, it takes 25 terawatts to power the world. But that number doubles every 25 to 30 […]

SOSV portfolio company unspun is taking a bold step toward reshaping how clothes are made in the U.S. The company, known for its near-zero-waste weaving technology, is planning to raise $40 million in project-level financing to build 10 factories across the U.S. These facilities will use AI-enabled 3D weaving machines designed to produce garments closer […]

SOSV portfolio company HexemBio recently spoke with Axios following its new $10.4 million Seed funding led by Draper Associates, with participation from SOSV, Seraphim, and others. The company is tackling a core driver of aging: the decline of blood stem cells that power the immune system. While past approaches (gene editing, chemical treatments, or transcription-factor reprogramming) often introduce instability […]

SOSV portfolio company Metabolic Psychiatry Labs is helping redefine how we understand mental health. Founder and CEO Dr. Shebani Sethi, a Stanford University researcher, studies the role of metabolic dysfunction in conditions like depression, schizophrenia, and other disorders. This week, she published a new peer-reviewed paper in Nature Mental Health and spoke to STAT News […]

SOSV portfolio company Aspect Aerospace recently spoke with SpaceNews about two major milestones: a $1.9 million Direct-to-Phase II (D2P2) SBIR award from the U.S. Space Force and a $500,000 pre-seed investment from SOSV. Aspect Aerospace is rethinking how spacecraft are designed and deployed with its Single-Board Satellite (SBS). Instead of launching one conventional spacecraft, Aspect […]

For years, the biotech industry has poured billions into targeting epigenetic disease, only to run into the same wall. Most drugs go after catalytic pockets on enzymes. But those targets often exist in both healthy and diseased cells, making it incredibly difficult to achieve precision without unintended side effects. That’s where SOSV portfolio company TippingPoint […]

Recognized “for creating a soil-powered battery for precision-ag sensors”, SOSV portfolio company Bactery was named to Fast Company’s list of Most Innovative Companies of 2026! Bacteries are batteries powered by bacteria. The rise of precision ag has put roughly a quarter billion sensors on farms worldwide, most of them depending on single-use batteries or complex […]
