Updated Sep 2026

Funded Energy startups in the United States (US) number 954 in FundedIQ, tracked with their funding rounds, amounts, investors, industries, locations and company details. This page provides an overview of the Energy startup funding landscape in the United States, along with the 100 most recently funded Energy startups in the United States.

Houston and San Francisco hold the deepest concentrations of these companies. Energy startups in the United States closed 636 funding rounds over the last 24 months, 305 of them in the last 12 months, and raised $94B in disclosed capital. The median disclosed round is $38M, with the middle half of rounds falling between $6.0M and $165M.

With Alumni Ventures and Coatue leading the way, capital is flowing toward foundational builds. This skew toward infancy means the focus is on early product validation and initial market entry.
