About us

Tetrax is an AI-powered climate-tech startup transforming how clean infrastrcture energy projects are assessed and de-risked. We help energy companies, developers, and investors move faster and safer by automating one of the most complex parts of the industry: due diligence, compliance, and project risk analysis.

Our core product, TetraxVerify, uses artificial intelligence to analyze massive volumes of technical, legal, and commercial project data in minutes instead of weeks—reducing risk, cutting transaction costs, and accelerating the global energy transition.

TetraxVerify supports solar, wind, battery storage, and other clean infrastructure assets, helping teams assess project readiness, identify risks early, and make better investment and development decisions. Our customers include renewable developers, IPPs, investment funds, and advisors across Europe who manage large, multi-country portfolios.
