Use these questions with any firm you are evaluating, including us:
A sensible choice for continuous monitoring and high-volume screening, where speed and coverage matter and each individual subject carries limited risk.
Fits when due diligence is one piece of a bigger engagement, such as valuation, restructuring or ongoing compliance work, and you want a single firm for all of it.
Fits when a specific subject, such as an acquisition target, an executive, a foreign partner or a distributor, needs verified, in-depth research and a clear answer.
Many organizations use more than one type. If you are unsure which category your subject falls into, we are glad to talk it through on a short call.
Larger firms offer due diligence as part of a broad range of advisory services. Kreller Group is a boutique investigative firm with senior investigators on every engagement, in-country research and reporting written for your decision. The right choice depends on your subject, scope and budget.
When the subject carries real risk, such as an acquisition target, an executive hire, a foreign partner, or a jurisdiction with limited public records, and the cost of a missed finding is high.
Enhanced due diligence, pre-transaction and M&A support, third-party and partner due diligence, executive and background due diligence, and complex corporate investigations.
Yes. Kreller Group works in 230+ countries and territories using in-country investigators.
