Amsterdam-based startup beSirius has secured €3 million in Seed funding to transform how sustainability is handled in some of the world’s most complex industries — metals, mining, and heavy industry. The AI-powered platform is on a mission to replace outdated, static ESG reporting with real-time sustainability intelligence that drives smarter decisions across procurement, investment, and strategy.
The round was led by NAP (formerly Cavalry Ventures) and joined by Fund F, Techstars, Blackwood, WEPA Ventures, and Golden Egg Check.
“Metals and mining power everything from clean energy to national defense. But the way we report sustainability in these industries is stuck in the past,” said Anastasia Kuskova, CEO and co-founder of beSirius. “We built beSirius so companies can stop drowning in reports and start using sustainability data to actually win deals, protect revenue, and guide strategy.”
Turning ESG from a Burden into a Business Driver
Founded in 2022 by Kuskova, Sergey Tyan (CCO), and Seva Martynov (CTO), beSirius was born out of deep industry experience. The founding trio brings over two decades of combined expertise in metals, mining, and industrial technology — and a shared frustration with the inefficiencies of legacy ESG systems.
Rather than merely tracking compliance, beSirius turns fragmented sustainability data into a strategic asset. At the heart of the platform is the ‘Sustainability Twin’ — a dynamic, digital profile that compiles and updates all relevant ESG data, making it machine-readable and instantly usable across the organization.
With this, the beSirius AI engine can respond to investor, regulatory, and customer queries in real-time — in exactly the format each stakeholder needs. The result? Over 70% less manual effort, faster insight into ESG gaps, and better preparedness for negotiations and audits.
Backed by Industry Giants
The platform is already gaining traction among major players, with FLSmidth, ArcelorMittal, and Freeport-McMoRan among the early adopters. These global giants are leveraging beSirius to not just stay compliant — but to drive faster, smarter decisions and build stronger relationships with investors and customers.
“ESG, as we’ve known it, is dead,” Kuskova added. “It’s no longer about ticking boxes — it’s about performance. beSirius acts as a ‘universal adapter’ for sustainability data, cutting through the noise and helping companies focus on what really matters.”
What’s Next for beSirius?
The fresh €3 million injection will help beSirius enhance its AI backbone, deepen integrations with financial institutions, supply chains, and auditors, and scale adoption across Europe and North America.
The startup has grown from a founding team of three to 17 employees, saving thousands of hours of manual ESG work along the way. With a rapidly expanding customer base and strong investor confidence, beSirius is positioning itself as the go-to platform for industrial leaders who want to make sustainability a competitive advantage.
“beSirius is making ESG data actionable — not just for reporting, but for real-world decisions,” said Stefan Walter, Managing Partner at NAP. “Their deep industry know-how and practical AI approach are already showing impact, and we believe they’re set to change how an entire sector approaches sustainability.”
