Why are people more responsive right after a job change?

New hires and recently promoted people are actively rebuilding relationships and evaluating tools, vendors, or hires for their new role, which makes them more open to relevant outreach than someone settled into a long-tenured position.

How long does the 'more reachable' window last after a job change?

There's no fixed window and little hard data on its length. It tends to be largest right after someone starts, while they're still forming their new network and reviewing tools, vendors and hires.

How do I track job changes across my whole network without checking LinkedIn daily?

A network search tool that surfaces job-change and promotion signals as a standing alert, like People by Sniff, removes the need to manually scroll a feed hoping to catch relevant updates.

How to Track Job Changes in Your LinkedIn Network (and Why It Matters)

When someone in your network changes jobs, they enter a short window where they're more open to conversations, more likely to need new vendors or hires, and easier to reach — which makes job-change tracking one of the highest-leverage signals available from your existing connections.

Why a job change is such a strong signal

New hires and newly promoted people are actively rebuilding their internal network, evaluating new tools and vendors, and often have hiring authority they didn't have before. All of that adds up to a window early in a new role where they're more open to conversations than someone settled in for years. There's no fixed length, and we haven't found good data that puts a number on it, but there is evidence that new leaders change suppliers: a study in the Journal of Financial and Quantitative Analysis found suppliers lose substantial sales after a customer company replaces its CEO.

What to do when someone in your network changes jobs

Congratulate genuinely, then follow up separately. A congrats message alone rarely leads anywhere; a short, specific follow-up a week or two later about something relevant to their new role performs better.
Check if the new company is a target account. A former colleague landing at a company on your sales or partnership list is exactly the kind of warm path worth acting on immediately.
Ask what they need. New hires are often building out their stack, team, or vendor list in the first few months — a direct, low-pressure "let me know if you need X" lands well here.

Why this signal gets missed

On a standard account, LinkedIn shows job-change notifications in a feed that's easy to scroll past, with no way to filter it down to "job changes at companies I care about" or "job changes among my strongest connections." Sales Navigator has a “Changed jobs in last 90 days” lead filter, but it's a paid sales tool. For most people the signal exists but isn't surfaced in a way anyone reliably acts on.

Turning it into a standing alert

The fix is treating job changes as a filtered alert rather than something you notice by chance in a feed. People by Sniff tracks job changes and promotions across your network and can be asked directly — "which connections changed jobs this month" — instead of relying on catching it in the moment.

The compounding effect

Acting consistently on job-change signals, even a few minutes a week, compounds over time: former colleagues scatter across companies, and every one of those moves is a fresh warm path into somewhere new, as long as you notice it while the window is still open.
