1
Zanskar
Country: USA | Funding: $157.2M
Zanskar specializes in exploration and development of geothermal energy sources. It has developed AI platform for searching for geothermal deposits and constructs power plants at discovered sources. The company uses modern drilling and computational geophysics technologies to discover new resources, de-risk known resources, and mitigate the risk of "dry holes." Zanskar addresses key challenges hindering the rapid expansion of geothermal energy by reducing exploration costs and increasing the size of each geothermal deposit. Zanskar currently holds the industry's largest portfolio of conventional geothermal development projects across the western United States. For example, in 2024, Zanskar acquired the Lightning Dock geothermal power plant, which had been operating at low capacity for several years. In less than a year, Zanskar restored the plant to full capacity and is now supplying power to the grid after discovering and drilling in a deeper, hotter zone.

DeepMind
Country: UK
DeepMind was acquired by Google as a leading ML startup and now acts as its mostly independent AI division.
