Moore Idman Oy

What Moore Idman Oy does

Moore Idman Oy is a Tampere-headquartered, Finnish-limited audit and professional services firm formed in early 2023 through the merger of Idman Vilen Oy and Moore Rewinet Oy. The firm provides six interconnected service lines: statutory auditing (the flagship practice, marketed with 98 years of combined experience), internal audit, ICT audit assurance, sustainability reporting assurance (CSRD/ESRS and double materiality assessment), M&A due diligence and advisory, and tax services. Customers are Finnish businesses of all sizes across multiple industries, including housing companies, corporations, and foundations, with no publicly disclosed anchor logos.

The underlying technology stack is conventional for a mid-tier audit firm: engagements rely on relationship-based professional delivery augmented by the IDEA analysis program for audit data examination and verification. No proprietary AI/ML, platform, or data product is present; differentiation rests on credentialed talent (KHT, HT, KRT, CIA certified partners), local market leadership in Tampere, and affiliation with the global Moore network spanning over 110 countries.

The business model is project-based professional services billed through custom quote-based engagements, with multi-year client relationships in statutory audit. The firm is privately held under a partnership structure with 16 partners/shareholders as of August 2024. Go-to-market combines direct sales via professional relationships, content marketing (expert blog articles, employee stories, ESG webinars), and referral flow from the Moore Global network. Revenue is not publicly disclosed; near-term strategic priorities under incoming CEO Jussi Savio (effective 1 August 2025) are a new development phase focused on growth following the post-merger integration.
