The philosophy

We believe there is such a thing as a good business. When we bring a business into the Sullivan Street fold our ambition is unlimited – the size of the companies we manage leaves enormous potential for growth. However, we also believe none of that will be tapped without first becoming a good business, with strong ethics, dedicated employees, good controls and processes and high quality, enthusiastic management. All supported by good stewardship from shareholders. Our philosophy is that in building a good business, the value will flow.

Our values

Our values are at the core of everything we do. They represent who we are and what we stand for, they guide our actions and behaviours; they influence the way we work.

The founders

The founders have been close friends for over 25 years and the strength of their partnership not only unites them but also creates a connection between operations and transactions, different from other private equity firms, which is inextricable from every aspect of origination, risk management, capital structuring and investment. They are both accountable for every aspect, at the highest level, to our investors and our companies. Our hunger for learning and improving makes us quick to hold ourselves accountable, believing only in that honesty accountability do we find improvement for the next investment.
