Betolar appoints Ville Sirviö as Chief Financial Officer
Betolar Plc has appointed Ville Sirviö as the company’s Chief Financial Officer (CFO) and a member of the Management Team. Sirviö served as CFO of Terrafame, a Finnish producer of nickel and battery chemicals, from 2016 to 2026.
”Ville was involved in building Terrafame into a Finnish metals company with a turnover of more than half a billion euros, and in securing the financing required for this growth. This is exactly the kind of experience we need now that Betolar has moved from technology development to commercial execution. He strengthens our cooperation with partners and investors as we scale our three businesses,” says Betolar’s CEO Vibeke Krohn.
Betolar utilizes existing materials more efficiently and protects them. The company recovers critical metals from mining tailings and industrial side streams, provides low-carbon materials for the construction industry, and protects critical infrastructure from physical threats.
As CFO, Sirviö will be responsible for finance and investor relations, and will play a key role in financing the growth of Betolar’s three businesses together with the company’s partners.
During Sirviö’s ten-year tenure as CFO, Terrafame’s net sales grew from EUR 2 million to approximately EUR 560 million in 2025. He played a key role in arranging the company’s financing, including approximately EUR 240 million in financing for the battery chemicals plant. Prior to Terrafame, Sirviö served as Finance Manager at talc producer Mondo Minerals in 2014–2016, and as Controller and Finance Manager at Talvivaara Mining Company in 2008–2014. He holds a Master of Science degree in Economics and Business Administration from the Helsinki School of Economics, majoring in accounting.
”Europe needs more of its own critical metals as well as better protection for the infrastructure that our society depends on. At Terrafame, I saw what it takes to finance and scale a Finnish metals business. Betolar has strong technology and partners who are ready to invest alongside the company, and I look forward to turning these opportunities into long-term value for our shareholders,” says Ville Sirviö.
Sirviö succeeds Mikko Wirkkala, who will leave Betolar on January 31, 2027, to pursue new opportunities outside the company. Sirviö will assume his role on January 11, 2027.
We thank Mikko Wirkkala for his contribution to Betolar and wish him all the best in his future endeavors outside Betolar, says Betolar’s CEO Vibeke Krohn.
