About Rami Cassis

Rami Cassis is an experienced corporate turnaround specialist and investor. As principal of Parabellum Investments, he acquires controlling stakes in underperforming companies for turnaround, before either appointing talented executive teams under his guidance or remaining as CEO to continue growing these businesses organically and through acquisition.

Operating across all industries and many countries and continents worldwide, he has a particular interest in corporate carve-outs, disposals, distressed businesses, siloed assets, non-core divisions, and special situations – generally preferring to take full control upon investing, when the case allows.

Parabellum Investments is funded exclusively by Cassis’ private capital, meaning he can make quick decisions on investments.

Outside of Parabellum, Cassis is a highly sought-after interim CEO, appointed by boards and investors to turn around underperforming companies on a short time horizon. This may involve stabilising cash and liquidity, restructuring a company’s cost base, refocusing the company’s strategy, and returning a business to growth.

Prior to his current work, Cassis built on his global background with a 10-year career at Schlumberger, starting as an operating engineer before holding a succession of management roles. He then continued in management positions with Atos, where he was Managing Director of BPO/ITO for the firm in the UK, after a period at KPMG Consulting as a board advisor.

He holds two degrees, one in Aerospace Engineering and the other in Pure and Applied Mathematics, both gained at the University of New South Wales in Sydney, Australia.
