LinkedIn Recruiter is the gold standard for outbound sourcing. If you need to reach someone who has not applied (a senior engineer at a competitor, a specialist who will not see your job post), Recruiter's database and InMail mechanics are unmatched. We are not trying to replace that. We do not source passive candidates. We do not message people who did not apply.
Picked makes the inbound funnel work. The people who saw the job post on Indeed, LinkedIn Jobs, your careers page, or a partner channel and clicked apply. Today, most of them go into a black hole. The recruiter is busy on outbound. The inbound pile gets a 30-second triage at best, and 90 percent of qualified candidates get ghosted. We fix that.
