Mariana Minerals combines proprietary software and capital project execution to build and operate mines and refineries for critical minerals. Its MarianaOS platform integrates CapitalProjectOS, PlantOS and MineOS into a single AI and machine learning stack intended to compress multi-year project execution timelines and reduce commissioning time. The company operates active projects including Copper One, which is ramping toward 50,000 metric tons of refined copper per year, and Lithium One, a GWh-scale facility targeting commercial lithium production from oil & gas produced water in the first half of 2027. Mariana has raised roughly $400 million of parent and project capital to date, including the $310 million Series B. The company plans to scale to 10 commercial-scale projects in 10 years, using data from each project to improve its software and lower costs for subsequent builds.

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.
