Overview
Onvest Oy is a Finnish family company whose roots go back to the plumbing business A. Onninen, founded in Turku in 1913; Onvest was set up in 1997 as the group parent. After Onninen was sold to Kesko in 2016 and a 2018 demerger, its business comprises real estate (Onvest Development), steel services (Feon Oy), wood construction (OnWood Oy) and industrial holdings, with Onvest Invest handling asset management.
