As capital continues to pour into renewable energy, one bottleneck remains stubbornly slow: due diligence. Barcelona-based startup TetraxAI believes artificial intelligence can fix that, and investors seem to agree.
The company has raised a €1.2 million pre-seed round led by Copenhagen-based climate investor The Footprint Firm, with participation from Norrsken Evolve and Carbon13. The round is complemented by non-dilutive funding from NEOTEC, Spain’s national deep-tech grant programme backed by the Centre for the Development of Technology and Innovation (CDTI), bringing TetraxAI’s total funding to €1.5 million.
The capital will be used to scale the platform across Europe, grow the engineering and machine learning teams, and accelerate commercial traction among developers, investors, and asset managers.
Fixing the slowest step in clean energy development
While renewable energy capacity is expanding rapidly, the processes behind project approval and financing remain largely manual. Legal, regulatory, and land-use due diligence often requires weeks of work across thousands of documents—slowing capital deployment and increasing execution risk.
TetraxAI is targeting this friction head-on. Its AI-powered B2B SaaS platform automates document analysis and combines it with local regulatory intelligence and structured project data. The result: faster, more consistent risk assessments for solar, wind, battery storage, and other clean energy assets.
According to the company, what once took several weeks—such as generating a full due diligence report for a utility-scale project data room—can now be completed in a few hours, at a fraction of traditional advisory costs.
A founder-led response to a systemic problem
TetraxAI was founded in 2024 after CEO and co-founder Marta Vizcaíno Martín repeatedly encountered the same issue from the inside of the industry. With more than 20 years of experience as an energy M&A lawyer and over 90 completed transactions, she saw firsthand how manual due diligence slowed deals and introduced unnecessary risk.
To build a scalable alternative, she assembled a founding team that blends sector expertise with deep technical capability. CTO Arnau Tibau Puig, PhD, previously led Walmart’s first algorithmic pricing systems in Silicon Valley, specialising in large-scale data infrastructure and production-grade AI. COO Ekaterina Filina brings operational and go-to-market experience from launching Amazon Flex across Europe and Asia.
Together, the team aims to modernise how clean energy projects are evaluated, financed, and brought to market.
“This round is a turning point for TetraxAI,” said Vizcaíno Martín. “Beyond the capital, we are partnering with investors who understand both climate impact and commercial scale. The funding allows us to expand geographically, deepen the product, and support decision-makers at the speed the energy transition requires.”
Building infrastructure software for renewable M&A
At the core of TetraxAI’s offering is TetraxVerify, a product designed to support renewable energy development and M&A workflows. The platform analyses thousands of documents within project data rooms and streamlines legal, regulatory, and land-use risk assessments for developers, investors, lawyers, and insurers.
The company positions itself as a new software layer for clean energy infrastructure—one that enables teams to move faster without compromising on risk discipline.
With the new funding, TetraxAI plans to extend its coverage across European energy markets while accelerating adoption among institutional investors and asset managers active in renewables.
The support of FPF, based in Copenhagen, will be key to TetraxAI’s expansion in Europe. In addition to capital, the company will offer the Spanish startup an extensive international network of energy developers, infrastructure investors, and industrial partners, which will be key to its commercial expansion.
“TetraxAI is addressing a problem that is both critical and often underestimated,” said Jakob Wichmann, co-founder and partner at The Footprint Firm. “By reducing the time, cost, and friction of clean energy due diligence, the company enables faster deployment of capital into sustainable infrastructure. This is exactly the type of climate-tech innovation we look to support.”
Norrsken Evolve, one of Europe’s leading impact-driven venture platforms, and Carbon13, an investor focused on science-based startups with megaton-scale climate impact, also participated in the round.
