What Leeuwendaal does

Leeuwendaal Advies B.V. is a privately held Dutch organizational advisory firm founded in 1990 and headquartered in Utrecht, Netherlands. The firm delivers human resources consulting, talent development, leadership development, executive search, interim management, assessments, and HR infrastructure services to public sector, healthcare, and education organizations in the Netherlands, with a smaller private-sector practice. Its core methodology is anchored by an exclusive partnership with Gallup (held since 2018) for the Dutch-speaking region, giving the firm sole rights to deliver, train, and certify the CliftonStrengths assessment (a 177-item instrument identifying 34 talent themes), the Q12 employee engagement framework, and the broader Gallup toolkit, including Dutch-language Gallup training materials developed in-house.

The product portfolio spans strengths-based individual and team assessments, executive and development assessments conducted by in-house psychologists, proprietary organizational tools (the Rolllenmodel role framework, HR21 for municipalities, Fuwasys for function evaluation, and Functiehuis Navigator for job-house structuring), compensation benchmarking, leadership development programs (including the MIOO program for research organizations and the Leeuwendaal Bruist traineeship), board-of-supervisor evaluations, and trust investigations. Around 210+ multidisciplinary professionals — including approximately 40 Gallup-certified strengths coaches, psychologists, organization advisors, executive search consultants, and labor-law specialists — deliver these services, supported by a partner alliance (Leeuwendaal Alliantie) with Hiemstra & De Vries, Lagerweij, and Holtrop Ravesloot.

Leeuwendaal operates a consultative, sales-led B2B go-to-market with strong event-, podcast-, and content-driven demand generation, targeting HR decision-makers and executive leadership in Dutch municipalities, healthcare institutions, schools, research organizations, and select private-sector clients. Revenue is generated primarily through project-based professional services engagements and multi-year advisory contracts, priced on inquiry, with a small self-serve revenue line from €28 individual CliftonStrengths Top 5 assessment codes. The firm holds ISO 9001:2015, ISO 27001:2023, ACP, CMC, CEDEO, NVO2, SPO, ROA, and NIP affiliations, and was ranked the #1 HR advisory service provider in the MT1000 in 2021.
