Aalo Atomics designs and builds factory-manufactured nuclear power plants for data centers, industry, and cities. AI infrastructure requires firm, high-density power on timelines the existing grid cannot support. The Aalo Pod delivers it as a complete modular power plant, mass-manufactured in a factory and sited directly at the load. In July 2026, the Aalo Critical Test Reactor achieved first criticality at Idaho National Laboratory as part of the U.S. Department of Energys Reactor Pilot Program. Construction of the pilot Aalo-X full-power 10 MWe power plant is underway. Founded in 2023 and headquartered in Austin, Texas, Aalo pairs nuclear scientists, engineers, and operators with builders from technology, defense, and manufacturing to eventually achieve 3¢/kWh nuclear electricity at scale, growing from 2 people to 200 in three years with $300M+ raised and an operational factory. Energy without limits, for everyone.

Turion Space is building the infrastructure to secure and sustain the future of space. Founded to address the growing need for space domain awareness, in-space servicing, and debris mitigation, Turion designs, builds, and operates spacecraft with real-world operational capability. Our vehicles are built for national security and commercial missions that require speed, autonomy, and resilience. We believe the next chapter of space operations will be defined by who can act, not just observe. That’s why we’re focused on building platforms that move fast, adapt in orbit, and solve problems ranging from satellite servicing to tactical intelligence gathering. We successfully launched our DROID.001 satellite in June 2023 and DROID.002 in March 2025. DROID.003 is scheduled for launch in 2026. https://x.com/TurionSpace https://www.youtube.com/@TURIONSPACE https://www.instagram.com/turionspace/

Robots have the potential to reshape our existence. Our mission is to leverage robotics to improve universal quality of life.  Robots will become one of the most impactful and effective tools humanity has ever created.  We believe robots should do the work humans don’t want to do. We pursue ambitious goals to make this a reality. We’re not satisfied making incremental improvements to the status quo but are driven to change the paradigm altogether.  Our robots are versatile, capable of solving numerous tasks with a single embodiment. Join us on the next phase of our journey as we get our systems out into the world to do the most meaningful work.

The trillions of microbes that call us home –the human microbiome – perform critical functions that preserve our health including helping develop our immune system, manufacturing nutrients such as vitamins, and harvesting energy from the diet. Alterations of the human microbiome are increasingly recognized as a key factor in autoimmune, metabolic, infectious and many other diseases. For millions of years, humans have co-evolved with this community of microbes, communicating in an ancient language that holds critical clues about how autoimmune and infectious diseases develop. This language is based on a system of signals that our resident microbes use to successfully colonize us, such as byproducts of bacterial metabolism and factors that bacteria use to adapt to human niches. Recent discoveries have shown that most of these signals do not lead to disease, rather, they promote our long-term survival. Vedanta is developing a novel class of therapies that modulate pathways of interaction between the human microbiome and the host immune system. Vedanta was co-founded by PureTech Health and a group of world renowned experts in immunology and microbiology
