Many highly successful tech founders continue building within the familiar realms of software and AI after major exits. But Co-Founder and CEO at Fourier, Siva Yellamraju, following multiple AI startup acquisitions by giants like Google and Apple, deliberately pivoted towards a far more complex challenge: energy resilience. He recognized that solving fundamental atomic-level problems, like efficient hydrogen production and storage, requires more than just innovation; it demands true engineering audacity.

Acting upon this realization, Siva co-founded Fourier not just to create a product, but to fundamentally reimagine how we approach energy infrastructure. By applying a software-defined, first-principles mindset learned in tech to the physical world of hydrogen, Fourier aims to bypass policy bottlenecks and build scalable, practical solutions for a resilient energy future, tackling what they see as the ultimate constraint on future progress.
