beSirius raises €3M to turn sustainability reporting into actionable data

Amsterdam-based beSirius has raised €3M in seed funding to accelerate the development of its sustainability intelligence platform for heavy industries. The round was led by Berlin-based NAP (formerly Cavalry Ventures), with participation from Fund F, Techstars, Blackwood, WEPA Ventures, and Golden Egg Check.

beSirius is targeting one of the most complex and carbon-intensive sectors of the economy: metals, mining, and heavy industrial manufacturing. The startup helps companies replace static sustainability reporting with machine-readable insights that can be used to guide procurement, investment, and strategic planning.

With the new seed funding, beSirius plans to invest in scaling its AI infrastructure, expanding platform capabilities, and deepening integrations with supply chain partners, auditors, and financial institutions. At the heart of beSirius is what the company calls the “Sustainability Twin” - a digital representation of a company’s sustainability profile that consolidates both qualitative and quantitative data, keeps it continuously updated, and makes it accessible through AI. The system can automatically respond to requests from investors, regulators, and customers in the required format, while identifying gaps and risks in sustainability performance.

Sustainability regulations are tightening globally, particularly in Europe, where the Corporate Sustainability Reporting Directive (CSRD) is expected to impact thousands of companies over the next few years. At the same time, investors, lenders, and large customers are demanding more transparency and standardisation in environmental, social, and governance (ESG) data.

“ESG as we’ve known it is dead. It’s no longer about reporting — it’s about business performance,” said Anastasia Kuskova, CEO and Co-Founder of beSirius.

“Sustainability teams are buried in endless requests — each stakeholder asking for data in a different way. It’s slow, manual, and keeps smart people stuck in reporting instead of shaping strategy. We built beSirius as the ‘universal adapter’: it turns scattered data into clear answers and gives teams the clarity to drive decisions that protect revenue and strengthen relationships.”

“Metals and mining are at the heart of everything that powers the modern world - energy, technology, and defence. But the industry is stuck translating complexity into static reports instead of using it to drive decisions,” said Kuskova. “We built beSirius, so companies stop firefighting reports and start using sustainability data to protect revenue, shape strategy, and win better deals.”

This is particularly relevant in capital-intensive sectors like mining and metals, where ESG performance increasingly influences access to capital and the ability to win contracts.

“beSirius is turning sustainability data into a strategic asset, thanks to the team’s deep industry expertise and practical, AI-driven approach,” said Stefan Walter, Managing Partner at NAP. “Seeing adoption among early customers, we believe beSirius is well positioned to help an entire industry to use data more effectively – improving decision-making and driving real impact across the value chain.”

beSirius was founded by Kuskova (CEO), Sergey Tyan (CCO), and Seva Martynov (CTO), who together bring over two decades of experience in industrial technology and sustainability. The company has grown from three co-founders to a 17-person team and has established a footprint in both Europe and North America.
