Sondeijker AND Partners

About Sondeijker AND Partners

Sondeijker & Partners delivers senior execution at critical inflection points—from Organizational Change to Business Transformation and Post-Merger Integration (PMI).

We design the shortest credible path from today’s operating reality to sustainable performance—and deliver it with senior, hands-on teams, a clear governance rhythm, and benefits tracking from day one.

What we deliver • Organizational Change — operating model, decision governance, stabilizing People & Shared Services • Business Transformation — HR digitization (Workday, SuccessFactors, Payroll/Time) + performance improvement in Supply/Operations and Commercial (RTM, pricing, CX) • PMI — Day-1 readiness, Day-100 delivery, value capture tracked to P&L

How we work Rapid Diagnostic → 90-day Execution Sprints → Run-state Handover.

Results delivered include backlog reductions (−40–60% in 8–12 weeks), 15–30% fewer tickets, and PMI value capture tracked to P&L. Selected engagements include ING, Vattenfall, Electrolux, DSM, ams AG, DS Smith, NTS Group, The Vegetarian Butcher × Vivera (PMI following carve-out from Unilever), Perfetti Van Melle × Mondelēz Gum business, and 5CA.
