Talent pool

A talent pool is basically your list of warm leads. These people already raised their hand once. They applied, they made it to the second round but someone else got the job, they left their details at an event, or they signed up to hear about new roles. They know who you are, and that's a big head start compared to a cold audience.

Most companies have a huge one without knowing it. It's sitting in the applicant tracking system as hundreds of old applications nobody looks at again. The value only shows up when you actually use it: tag people properly, keep the data clean, and reach out when a matching job opens, before you spend a cent on ads.

What makes it work is how you left things with them. If someone got ghosted last time, they're not really in your pool anymore. If they got a kind rejection and a "we'll keep you in mind," they might actually pick up the phone.

Example

A recruitment agency opens a new role for a payroll specialist. Before launching a campaign, they search their system for people who applied for similar roles in the last year and reached at least a first interview. They find a handful, send a short personal message, and two people book a call that same week. No ad spend at all.
