About Parabellum Investments About Parabellum Investments



Led by our founder Rami Cassis, Parabellum Investments is a highly operational investor bringing together a team with a broad range of competencies & backgrounds including entrepreneurship, corporate executive leadership, operations, legal, HR, finance and PR & Marketing.

How we differ


A hybrid between a family office and private equity

We mainly deploy our own funds to acquire controlling stakes in operating companies. We make decisions quickly, transparently and free from the influence of opaque investment committees.


The decision maker is the operator

Deals are struck directly with the decision-maker whose background is vastly different from the majority of investment principals. Moreover, we have a diverse team from a broad range of disciplines so are able to look at problems practically and creatively.


First hand management experience

Given our collective backgrounds, we truly understand the challenges of leading a business and are able to relate to management in a way most investment professionals cannot.


code of

Our word is our bond. The way we engage with any stakeholder is always respectful, open and principled. Conscious of never wasting anyone’s time, we are decisive and do not volunteer opinions if we do not feel sufficiently informed to do so. In transactions, we qualify deals quickly and set price expectations early. We neither change our mind at the last minute nor price chip.

We use
our own

We use our own capital so we truly understand what it takes to put money at risk and the journey required to get there. There is no investment committee, pre-defined investment mandate or external investors to answer to, meaning decisions are quick and unpolitical, with dialogue directly with the decision maker.

Transactions are never executed with an exit in mind and there is no prescribed time frame to “exit”. The typical three to five year investment horizon does not apply – indeed Parabellum Investments has been an investor in some companies for over ten years.

The type
of deals
we look for

We acquire firms in enterprise software, Business & IT services as well as mining & energy anywhere in the world. We have a strong pedigree of operating across numerous sectors including financial services, banking, telco, pharmaceutical / life sciences and oil & gas. Our investee operations are international with a global presence spanning North & South America, Europe, the Gulf and the Far East.

We deploy our own funds and generally seek to acquire the entire share capital or a controlling stake in a company.

How we work

The way we work is important to us because it reflects the shared values and style across the team. This fosters an environment where the investee companies feel supported and constructively challenged rather than burdened with inane reporting or trapped in endless board meetings.

However, it also means Rami and the team can step in if things go wrong. The core of the Parabellum Investments team has been together for almost ten years.

We are acutely aware of the importance of continuity of service post-acquisition and the protection of the vendor’s reputation, especially in the case of corporate disposals.

Who we
buy from

Our deal flow is varied but typically, we tend to acquire companies either from large corporate groups seeking to dispose of non-core assets to a reputable and operational buyer or from owner / operators who are also keen to ensure the business is sold to an operational buyer who will ensure continuity of trading and employees are well looked after.
