The warmest trigger in business development
Most business development starts cold, with a signal about a company and a stranger to write to. A hiring manager who has bought from you and then changes employer is the opposite. They know how you work, and they are in a job where they need to show results, often with a team that has gaps in it.
The difficulty is finding out. People do not tell their recruiters when they move. You learn it when an email bounces, or when you see the announcement weeks late, or not at all. Meanwhile your CRM keeps them at the old company and your next campaign goes to an inbox nobody reads.
This play finds the contacts who have moved and treats each move as two leads rather than one.
What you get back
A table of the contacts who moved: the company on your record, the company they joined, their title there, and the date of the move where the source gives one. For each destination company, a verdict against your ideal client with the reason. For the ones that pass, a verified work email and a drafted first message. A second list covers the accounts they left. The proposed CRM changes wait for your approval, and the sequence is staged and paused.
Variations worth knowing
Find the successor. For an account that matters, a company-scoped people search can find whoever took the seat your contact left. It is a paid step, so it runs for the accounts you name, not for every mover.
Watch a short list closely. Your best fifty buyers make a small run, and they are the people whose moves you can least afford to miss. That segment is the one worth repeating.
Promoted, not moved. The same check reports promotions. A contact who steps up at the same company has a wider remit and often a bigger hiring plan. For the candidate side of the same signal, see get back in touch with candidates who were promoted or changed job.
Where this goes wrong
Treating no match as no move. A signal provider only knows about the people it can match to its own records. A contact it cannot find comes back with nothing, and nothing is not proof that they are still in the same chair.
Following someone to a company you cannot serve. Loyalty to a contact is not a reason to pitch a business outside your market. The qualification step exists to stop that before it costs anything.
Writing as if you were strangers. A templated opener wastes the one advantage you have. Say what you did together and keep it short.
Letting the update erase the history. The fact that this person bought from you at the old account is worth keeping. When you review the proposed changes, decide whether the contact should be updated in place or added again under the company they joined.
