Gabriella Sebők — MBA, FCCA
Interim finance leadership for organizations mid‑transformation.
I step into senior FP&A, consolidations and finance control roles — closing gaps, steering S/4HANA rollouts, and keeping complex, multi‑entity finance operations under control.
About
The person behind ProFor IM
I'm Gabriella Sebők, MBA, FCCA — a senior finance manager who has spent the past 25 years inside the finance functions of complex, multinational organizations: apparel and sports, media and entertainment, gaming, classifieds, leisure and FMCG.
Since 2018 I've worked almost exclusively on interim assignments — stepping in as consolidations lead, FP&A manager or finance controller exactly when an organization needs senior capacity fast: a maternity gap, an ERP transformation, a reporting function under strain.
