L11 Advisory is a boutique finance advisory firm providing flexible support across the full finance function — from financial reporting and management information through to senior CFO and strategic advisory.

We work with businesses that need stronger financial structure, clearer reporting and experienced finance support without necessarily building a large in-house team. Our approach is practical, commercially focused and tailored to the needs of each business.

Founded by Ewelina Prejs Sochacka, FCCA, L11 Advisory brings more than a decade of experience across accounting, financial reporting, management reporting, group finance and senior finance leadership in international business environments.

Our aim is simple: to give businesses the right level of finance support when they need it — from getting the fundamentals in order to providing senior-level financial insight and advice.
