• Hephae Energy Technology

  Led · Series A · Jul 2026

  Hephae Energy Technology develops ultrahigh-temperature robotics, including drilling systems designed to enable precise well positioning for geothermal projects by overcoming temperature and reliability limitations of conventional drilling tools. Its technology aims to access deeper, hotter rock to support expanded geothermal energy development and to increase drilling speed and reliability. The company is led by CEO Steve Krase and is based in Houston, TX. Financially, Hephae has now raised a total of $24.7M following its $17.8M Series A. The newly raised funds are intended to accelerate commercial deployment of its advanced drilling systems and move the company toward broader market commercialization.

• Critical Energy

  Participated · Seed · Jun 2026

  Critical Energy designs and manufactures modular turbines and turbomachinery aimed at speeding deployment of geothermal power plants. The company leverages founder Spencer Jackson's SpaceX turbomachinery experience to produce factory-built modules that can be assembled faster than large, site-assembled turbines. Its immediate plan is to build a 2.5 megawatt turbine module as its first project, with a 5 megawatt module in development for enhanced geothermal operators. The first plant using its turbines is slated for completion by 2027. Financially, Critical Energy has raised $19 million in seed equity and $3 million in venture debt, totaling $22 million in early capital. The company projects rapid scaling, targeting gigawatt-scale output by the early 2030s and a long-term goal of producing 300 gigawatts of capacity per year by 2045.

• Panthalassa

  Participated · Series B · May 2026

  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.

• Derapi

  Participated · Seed · Feb 2026

  Derapi builds the connective software infrastructure that allows distributed energy resources (DERs) to plug into grid programs through a single, standardized API. Its platform offers secure data access, device control, and authorization, turning fragmented devices into coordinated grid-scale assets for utilities, virtual power plant operators, and energy software providers. The company is led by veterans from EnergyHub, Enphase, AutoGrid, and Proterra who aim to eliminate integration complexity in the rapidly expanding DER ecosystem. Customer feedback, including from Uplight, indicates that Derapi dramatically shortens the time required to onboard new battery partners. With electricity demand rising and grid reliability under pressure, Derapi positions itself as the trusted interoperability layer that unlocks flexibility and resilience. The newly secured funding will expand the team and support connectivity for millions of smart energy devices across the United States. Although the company has not disclosed revenue or user numbers, its focus is on scaling adoption of its universal integration layer among energy innovators.

• Zanskar

  Participated · Series C · Jan 2026

  Zanskar combines artificial intelligence, modern drilling techniques, and computational geoscience to find, assess, and develop geothermal energy resources. The company has a portfolio of greenfield geothermal projects, including the Lightning Dock site in New Mexico and recent discoveries at Pumpernickel and Big Blind in Nevada, plus two announced discovery sites in Nevada. Financially, Zanskar completed a $115 million Series C in January 2026 (later expanded with additional investment from Just Climate) and has now closed a $40 million revolving Development Capital Facility structured to scale to $100 million. Zanskar plans to use the new facility to fund pre-construction work and bridge projects to traditional project financing so it can rapidly build multiple geothermal power plants. The company aims to deliver gigawatts of clean, firm power to U.S. customers and expects to create hundreds of jobs as it scales development. Zanskar markets its approach as making geothermal more predictable, lowering development costs, and enabling large-scale deployment of dispatchable baseload power.
