beSirius

beSirius is an Amsterdam-based cleantech startup founded in 2022 by Anastasia Kuskova, Sergey Tyan, and Seva Martynov. The founders bring 20+ years of combined experience in mining, metals, and sustainability, with backgrounds at Tesla and the World Economic Forum. The company completed a €1.2M pre-seed round in January 2024 and a €3M seed round in April 2025, backed by investors including Techstars, NAP, Fund F, and Blackwood Ventures.

beSirius is explicitly mining and metals-focused rather than a generic ESG tool. The platform has been adopted by FLSmidth, ArcelorMittal, and Freeport-McMoRan. It is listed on Gartner Peer Insights in the ESG Management and Reporting Software category. The company claims to reduce manual ESG reporting effort by over 70–80% through AI automation.
