Honestly. I work with multiple operators across multiple jurisdictions, and there will be overlap. The handling is straightforward: full disclosure of any potentially competing engagement before the engagement letter is signed, no information bleed between clients, and a willingness to decline where the conflict is too direct.
The discipline of operating across multiple operators is the discipline of treating each operator engagement as fully separate. Information, decisions, and analysis from one operator never inform recommendations to another. When the same vendor question (which CRM platform, which payment processor, which KYC provider) arises across multiple operators, each operator gets the recommendation that fits their specific operator-side situation, independent of what was recommended to another client.
There are cases where the conflict is too direct to take both engagements. Two operators competing for the same regulated-market licence application is an obvious example. Two operators with materially overlapping VIP segmentation in the same regulated market is another.
In those cases, the second engagement is declined, the first operator stays the client, and the second operator gets pointed to other capable operator-side consultants. The full disclosure happens before any engagement letter is signed. Operators have the right to know the existing client portfolio shape (anonymised by sector and geography) before committing to an engagement.
