Conflict of Interest Checks: Uncovering Hidden Ties Before a Tender, Deal or Appointment

How to check for a conflict of interest on a tender committee, with a CEO or with a decision maker in a deal: which ties to look for, which sources to use, and what to do with the findings.

Modi Ben Shaul Updated 29 Oct 2026 2 min read

Past work together, family ties, a private company in an adjacent field. Ties like these almost never appear in the minutes, but they almost always leave traces in open information.

What is a conflict of interest

A conflict of interest is a situation in which the person making a decision has a personal, business or family interest that could influence it. It doesn’t necessarily mean wrongdoing, but it justifies a check, and sometimes it changes the whole picture.

Where it affects you

  • Tenders: a tie between a committee member and the winning bidder.
  • Management: a CEO who privately owns a company in a field adjacent to the company he runs.
  • Deals: a person who is supposed to make a decision and is connected to one of the parties.
  • Legal proceedings: prior links between litigants and the person deciding the case.

What a check looks for

A conflict of interest check looks for connections between people and entities:

  • Previous work in the same organization or on the same project.
  • Family ties and social connections.
  • Ownership of or office in companies, and shared boards of directors.
  • Shared addresses, phone numbers or representatives.
  • Shared posts, photos and events on social networks.

Every such finding is checked against another source. A link that appears only once, in a single source, is still just a hypothesis.

What it looks like in practice

A company that lost a tender, after investing heavily in preparing for it, asked me to check whether the committee that decided it had a conflict of interest with the winning company. In another case, a major investor in a public company asked whether the CEO had a conflict of interest, given that he privately owned a company in an adjacent field.

In both cases the question was focused, and the deliverable was a documented intelligence picture that could be handed to a lawyer or to management.

What to do with the findings

The findings are documented together with their sources, so you can work with them: present them to management, pass them to a lawyer, or decide there is nothing more to check. A negative answer is an answer too, and it saves an unnecessary proceeding.

All FAQs
Who commissions a conflict of interest check?

Companies that lost a tender, investors, directors, lawyers and parties to a deal, when there is a suspicion that a decision maker is connected to one of the sides.

Is the check done without the other side knowing?

The check relies on open sources only, so it doesn’t require contacting the person being checked. It is carried out within the law.

What if nothing is found?

That is an answer too. It lets you decide with more confidence, and sometimes saves an unnecessary legal proceeding.
