Antares is a nuclear fission energy company building factory-produced, transportable microreactors that deliver strategic power for mission-critical systems across land, sea, and space. Founded in 2023 and headquartered in Torrance, California, its R1 reactor uses TRISO fuel, sodium heat pipes, and a nitrogen Brayton cycle to produce 100kWe-1MWe for six-plus years. In June 2026 its Mark-0 reactor became the first privately developed advanced reactor to achieve criticality under the U.S. Department of Energy's Reactor Pilot Program.
Neno Duplan is the founder and CEO of Locus Technologies, a Mountain View-based company he bootstrapped in 1997 to become one of the world's first cloud-based environmental, health, and safety (EHS) software providers. Born in Croatia and trained as a civil engineer, Duplan earned his Ph.D. at the University of Zagreb, an M.S. from Carnegie Mellon, and advanced management training at Stanford. He pioneered the commercial SaaS model for environmental data management - deploying the world's first such product in 1999 - and has spent nearly three decades helping governments, utilities, and corporations track, manage, and report their environmental footprints. With more than 30 technical papers published, 11,000+ active users, and a 98% customer renewal rate, Duplan has built Locus into a durable, self-funded software company at the intersection of environmental science and enterprise technology.
Brian Potter is a structural engineer turned writer who publishes Construction Physics, a Substack newsletter with 72,000+ subscribers covering industrial technology, manufacturing productivity, and why buildings still cost so much to build. A Senior Infrastructure Fellow at the Institute for Progress, he spent 15 years in construction - including a front-row seat to the $2B collapse of Katerra - before channeling his frustration into some of the most rigorously researched long-form writing on industrial systems published anywhere. His first book, The Origins of Efficiency, was published by Stripe Press in October 2025.
Doomberg is the pseudonymous green-chicken persona behind the most-read finance newsletter on Substack, with 373,000+ subscribers. Run by a tight-knit team of former heavy-industry executives and private-equity professionals, Doomberg delivers lateral-thinking analysis on energy, finance, and geopolitics - unapologetically pro-nuclear, data-driven, and fiercely independent. Launched in May 2021, the publication grew from zero to the #1 finance newsletter on Substack without spending a dollar on marketing, making it one of the most remarkable organic media success stories of the independent publishing era.
Zephyr Fusion is building the first in-orbit fusion power source - a compact, megawatt-class reactor designed to run in the vacuum of space. Founded by two physicists who met in grad school operating a spherical tokamak, the San Diego-based startup uses a levitated dipole magnetic confinement approach with high-temperature superconductors. Their bet: space makes fusion easier, not harder. With launch costs down 10x and mass-produced HTS tapes providing 10x more field per kilogram, Zephyr Fusion aims to power the industrial revolution that humanity is about to have off-planet.
