Executive Diligence Takes on Greater Role in Senior-Level Hiring

This article was originally published at Hunt Scanlon Media.

September 29, 2026 - Executive search increasingly extends beyond assessing experience, leadership style, and cultural fit. For boards and investors, understanding a senior candidate’s background, reputation, and potential risk profile has become an important part of evaluating whether that individual is equipped to lead in a high-stakes environment.

That has made investigative diligence a more meaningful component of senior-level hiring and deal-related talent decisions. When handled effectively, the process can help search committees and private equity firms distinguish between material concerns and explainable issues, while providing added context around integrity, judgment, management history, and potential reputational risk.

Determining whether a finding is truly significant requires more than identifying an issue on paper; it demands context, judgment, and a clear understanding of how that information relates to the executive and the role. “The key distinction is whether a finding changes the understanding of the individual or the risk that they present,” said Michael Karran, a managing director of Mintz Group, a corporate investigations firm that gathers information before hiring, before transactions, during litigation disputes and after frauds, all over the world. “I would consider the severity, credibility, relevance, and recency of said findings, and whether there is a broader pattern.  Just as importantly, I would look at how the individual responds when confronted with the issue.”

“A discrepancy may be easily explainable; an inability or unwillingness to provide a credible explanation – or evidence of concealment – can be much more significant,” Mr. Karran added. “Our role isn’t to turn every negative fact into a red flag, but to establish the facts, provide context, and help the client understand what is genuinely material to the decision.”

So what raises the most red flags for a hiring organization? “The most serious concerns tend to involve dishonesty, concealment, repeated misconduct, or behavior directly relevant to the executive’s role,” Mr. Karran explained. “This can include fabricated credentials, material resume misrepresentations, serious or repeated inappropriate online conduct, credible reputational allegations, or offenses involving fraud, violence, harassment, or abuse of authority. Context is critical, however. An isolated incident from many years ago is very different from recent or repeated misconduct.”

CEO Candidates

For a CEO candidate, the focus is primarily on understanding the individual’s integrity, leadership history, reputation, and claims about their experience and accomplishments, as well as their fit with the company and investment thesis, according to Mr. Karran. “For an existing management team, the scope is broader: understanding what the investor is inheriting, including management dynamics, retention and succession risks, historical misconduct, conflicts, and potential cultural or operational issues,” he said. “Post-close, the focus can shift toward managing and remediating identified risks.”

“Ideally, people diligence should begin early in the deal process, with the depth of work increasing as the transaction progresses,” Mr. Karran said. “Early diligence can identify issues that may affect the investment thesis, leadership selection, or valuation, while deeper confirmatory work can assess key executives, succession, retention, and management risks.”

“Starting early also gives investors time to investigate ambiguous findings properly, rather than making rushed decisions immediately before signing,” Mr. Karran continued. “It allows people diligence to become not just a risk exercise, but a tool for leadership selection, succession planning, and post-close integration.”

The biggest mistake Mintz Group has seen over the years is treating a negative finding as a conclusion rather than the starting point for further questions. “Investors can overreact to unverified allegations, overlook important context, or focus too heavily on sensational findings while missing less obvious patterns of behavior,” Mr. Karran said. “They may also approach diligence looking to confirm an existing view rather than objectively test it. The goal isn’t to determine whether someone is simply clean or “not clean,” but to understand what we know, what we don’t know, and what could materially affect the decision.

Mintz Group, backed by ICV Partners, is a global investigations firm with more than 280 people and 12 offices worldwide. The company specializes in helping clients vet prospective hires, diligence potential deals and navigate their way through disputes, among other things.
