Siili Solutions Oyj’s governing bodies are the Board of Directors (hallitus) and the Managing Director / CEO (toimitusjohtaja), supported by a Management Team. At the Annual General Meeting held on 8 April 2026 the number of Board members was confirmed at five, and the following were (re-)elected: Harry Brade (hallituksen puheenjohtaja / Chair, on the Board since 2018), Jesse Maula (varapuheenjohtaja / Deputy Chair), Henna Mäkinen (Chair of the Audit Committee), Katarina Cantell, and Sebastian Nyström (first elected 2025). The annual report notes Harry Brade is non-independent of significant shareholder Lamy Oy.

The registry card synced from PRH lists 17 associated officer entries in total and shows some given names that differ from the company’s own releases (for example for “Cantell” and “Savusalo”); where they conflict, the company’s official stock-exchange releases and annual report have been used.
