Fourier

Fourier is an energy technology company building on-site, on-demand hydrogen production systems. Its core product is a modular, scalable device that generates hydrogen where it is needed, removing the transport and storage barriers of conventional hydrogen supply. Fourier targets three application areas: long-duration distributed storage for renewable energy, alternative fuels for heavy transportation, and cleaner feedstock for chemical and manufacturing industries. The company commercially launched its onsite hydrogen system in late 2025 and raised an $18.5M Series A led by Paramark Ventures and General Catalyst. Fourier is a hardware and infrastructure company and does not currently publish a public API, developer portal, SDKs, or other software developer surface.

Fourier is profiled on the APIs.io network. Tagged areas include Company, Energy, Hydrogen, Clean Energy, and Climate Tech.

Fourier’s developer surface includes engineering blog and 2 more developer resources.
