There are few benchmarks in our industry that carry the weight of the annual Chambers & Partners survey. Its rankings are not the product of self-nomination or marketing spend. They are compiled through direct interviews with the clients and peers who work alongside investigations firms on their most demanding matters. That is precisely why this year’s results mean so much to us.
Sigma7 Business Intelligence has once again achieved top rankings in the Chambers & Partners survey of business intelligence and investigations firms, maintaining the strong results of previous years.
The Rankings
- Band 1, Global Investigative Due Diligence, for the sixth consecutive year
- Band 2, Global Asset Tracing and Recovery
- Band 2, Litigation Support, Business Intelligence and Investigations, UK
- Oliver Gorton, ranked Band 1 for Global Investigative Due Diligence
Six consecutive years at Band 1 for Global Investigative Due Diligence is not a milestone reached by accident. It reflects a sustained standard of work, matter after matter, across jurisdictions and across some of the most sensitive briefs our clients can bring to us.
In Our Clients’ Words
The most valuable part of the Chambers process is hearing, unfiltered, how clients experience our work. This year’s commentary speaks to the qualities we hold ourselves to.
On judgment and rigor:
“Sigma7’s work has been top-notch. They are very detailed without losing focus on the overall context. They also do a good job of balancing and weighing conflicting evidence without jumping to conclusions. We have overall appreciated their ability to handle highly-sensitive issues.”
On analysis that goes beyond the public record:
“Sigma7 showed strong analytical judgement in identifying corporate affiliations, financial exposures, and cross-border operational links that were not readily apparent from public records alone. Their responsiveness, professionalism and willingness to tailor their analysis to our specific legal needs distinguished them from other firms we have worked with.”
On actionable, bespoke intelligence:
“Rather than generic outputs, they customise due diligence reports based on the client’s risk appetite, industry and transaction context, making findings more actionable.”
“At Sigma7, it’s not just about the information, it’s what they do with it. The results and advice are really good quality.”
On litigation support and integrity:
“Sigma7 has excellent contacts and regional expertise, a gift for developing intelligence that fits in with litigation tactics and objectives, and an excellent rapport with clients and counsel. The agency also demonstrates a high standard of ethics and integrity.”
And on Oliver Gorton’s individual Band 1 recognition:
“Oliver provides excellent client service, has a very significant depth of knowledge and expertise in areas and topics of interest to our firm, and applies a commercial awareness which is well suited to our needs. He just really gets it.”
What This Recognition Means
Intelligence is only as valuable as the decisions it enables. The consistent thread in this year’s feedback is not simply the depth of our research but the judgment applied to it: weighing conflicting evidence carefully, tailoring findings to a client’s risk appetite and transaction context, and delivering analysis that stands up in the boardroom and the courtroom alike.
We are grateful to the clients, peers and colleagues across the investment, legal and compliance communities who gave their time to Chambers for this survey. Their trust is the foundation of everything we do.
And to every member of the Sigma7 Business Intelligence team: this recognition is well deserved. Congratulations.
