Panthalassa builds self-propelled, autonomous floating nodes that capture wave energy to generate continuous clean electricity and run AI inference computing onboard, transmitting results to land via low-Earth-orbit satellites. The company has spent about a decade developing its power generation, propulsion, autonomy, and at-sea computing technologies and demonstrated capabilities with Ocean-1, Ocean-2, and Wavehopper prototypes in 2021 and 2024. Panthalassa plans to deploy its Ocean-3 pilot node series in the northern Pacific in 2026 to demonstrate AI inference at sea and to refine manufacturing ahead of commercial deployments in 2027. The platform uses the ocean for free supercooling to extend chip lifetimes and avoids transmitting power to shore by performing computing onboard. The company is a public benefit corporation headquartered in Portland, Oregon, and recently raised $140 million in a Series B to complete a pilot manufacturing facility and accelerate initial deployments.

Founded in 2023 and based in Reno, Nevada, Positron develops energy-efficient AI inference hardware, including its shipped Atlas inference system. Atlas has already been delivered to customers such as Cloudflare, and the company claims its hardware can deliver more than 3.5x performance per watt versus Nvidia's latest products on certain inference workloads. Positron is developing a next-generation chip called Asimov, targeting tape-out in late 2026 and production in early 2027. The company emphasizes U.S. manufacturing and energy efficiency as core differentiators. Positron has raised roughly $309 million to date, including a $230 million Series B in February 2026 that valued the company above $1 billion. CEO Mitesh Agrawal has led the company since before its seed round.

Aether Biomachines combines purpose-built artificial intelligence with high-throughput robotics to create proteins that function as molecular assemblers for manufacturing and environmental applications. The company’s proprietary Protein Function Model, trained on in-house experimental data, has already generated seven new protein classes capable of extracting rare earth metals, recycling plastics, capturing CO₂, degrading PFAS, and enabling complex pharmaceutical synthesis. Its first commercial materials, RapidPrint and Ultra, are polymer additives that allow 3D-printed parts to be produced up to 10× faster and with 2× the strength of current industry benchmarks, a key advantage for defense and aerospace customers. Aether plans to scale these materials products while expanding its protein-design platform to address additional industrial challenges. The firm positions itself as a catalyst for a new industrial revolution by replacing large, costly chemical plants with nanoscale protein machinery that works more efficiently and sustainably. Total capital raised now stands at $64 million, providing resources to accelerate product commercialization and deepen partnerships across manufacturing, sustainability, and national security sectors.

Villa is a San Francisco-based offsite homebuilding platform that applies modern offsite construction methods and technology to efficiently build housing. It partners with a wide network of offsite manufacturers to act as a demand-aggregation and fulfillment platform, offering end-to-end services from discovery and feasibility through permitting, installation, project management, and post-completion service. Villa also operates as a merchant homebuilder and principal developer with capital partners and follows a capital-light business model. Its tech-forward approach leverages AI, machine learning, and software tools to boost construction efficiency, and its supply chain includes some of the largest offsite factories in the U.S. In 2024 Villa launched its primary homebuilding segment and has constructed several hundred ADUs across more than 100 local jurisdictions, becoming one of California’s largest builders of detached ADUs. The company has expanded operations into Colorado and is pursuing entry-level home development through a PropCo JV, with plans to begin delivering homes for sale later this year.

Aether builds a molecular assembler platform that combines high-throughput robotics, machine learning, and synthetic biology to map millions of enzyme-reaction combinations and engineer nanoscale machines from protein building blocks. The platform can extract lithium from previously-inaccessible reserves and create enhanced products across automotive, healthcare, home electronics, and other industries. By generating large volumes of experimental data, the company engineers new classes of nanoscale machines that operate with the power and sophistication of gigantic chemical factories at nanometer scale. Led by CEO Pavle Jeremic, Aether said it will use the Series A proceeds to scale its platform and expand engineering, machine learning, and hardware teams. The company will initially focus lithium extraction in southern and middle U.S. regions, including Oklahoma and Arkansas, and will target Texas and Oklahoma for extraction from oil and gas wastewater and capped oil wells. Aether is based in Menlo Park, California.
