• Atana Elements

  Participated · Seed · Jun 2026

  Atana Elements uses proprietary AI and machine-learning models combined with deep subsurface expertise to identify and de-risk overlooked mineral deposits. The company claims it can accelerate discovery timelines to roughly 22 months, compared with the typical five-to-ten year cadence. Atana is currently focused on lithium exploration, with plans to expand into helium, hydrogen, and copper. It already has projects underway across the EU and the Americas. The company is led by CEO Thomas Wilson. Financially, Atana recently closed a $27.5 million seed round from Overture Ventures to support its ongoing exploration and growth activities.

• Magrathea

  Participated · Series A · May 2026

  Magrathea develops a next-generation electrolytic process to extract magnesium metal from seawater and waste brines with a goal of producing carbon-neutral magnesium. The company operates a pilot facility in Oakland, California and is led by CEO Alex Grant. Magrathea positions its product to reduce reliance on traditional mining and on Chinese supply chains for magnesium. Following the Series A, the company intends to expand operations and continue development work, including building a demo smelter. Financially, Magrathea has just completed a $24M Series A; no revenue or user metrics were reported.

• 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.

• Hammerhead AI

  Participated · Seed · Nov 2025

  Hammerhead AI is a San Francisco-based startup developing the orchestrated RL control agents (ORCA) platform, which deploys reinforcement-learning agents to deliver power-aware orchestration for AI factory operators. By transforming power constraints into actionable strategies, the platform boosts token-processing capacity and, in turn, revenue and shareholder value without waiting for grid expansions. Led by CEO Rahul Kar and CTO Rajeev Singh, the company positions itself as a critical layer between infrastructure OEMs and large-scale AI compute facilities. Hammerhead AI plans to use its new capital to accelerate product development, expand global deployments, and deepen collaborations with infrastructure providers and AI factory customers. The $10 million seed round marks the company’s first disclosed financing and provides the resources to scale both engineering and go-to-market operations.
