Endurance Energy

Endurance Energy is a renewable-energy developer building subsea geothermal power systems that harness volcanic activity beneath the seafloor to generate continuous, weather-independent electricity. Its first product, Adelie, is a planned 100 kW subsea power system slated for deployment in September 2026 at the Axial Seamount caldera off the Oregon coast, targeting island nations, industrial facilities, and data centers that need firm baseload power. The company is venture-backed (a Series A led by Founders Fund) and surfaced in the API Evangelist network as a Felicis portfolio company. As of this profile it publishes no public developer surface, API, SDK, or documentation; this entry captures the company identity and probed domain-security posture.

Endurance Energy is profiled on the APIs.io network. Tagged areas include Company, Energy, Renewable Energy, Geothermal, and Clean Energy.
