We work with investment banks, hedge funds and asset managers, giving them insight, rigour, clarity and, above all, confidence.

Our aim is to be the most trusted due diligence and compliance specialist, one deal at a time. As former investors and underwriters, we bring a unique, comprehensive understanding of the transaction lifecycle. We set out to offer the kind of service that we wanted ourselves: thorough, astute and well-presented, leaving clients in no doubt as to where we, and they, stand.

Quadrin has the global reach and professionalism that you’d expect of a major player, but as a boutique we can be far more nimble, responsive and flexible. Our experienced team offer a bespoke service to suit each transaction, spanning not only operational and regulatory compliance but also critical technological vulnerabilities such as cyber security and data protection.

Our banking background means that we know exactly what our clients need. They trust us to tell it like it is, leave no stone unturned and provide them with clear, in-depth, independent advice. We take a constructive approach to assessing and protecting assets, but we’re never afraid to make the tough calls. At Quadrin, we’re the experts on your side of the table.
