Features & Capabilities

LeadCull is a LinkedIn extension designed to help you stop losing relevant profiles you come across.

While browsing LinkedIn, LeadCull allows you to:

Save a profile with one click
Add custom tags to qualify contacts, prospects, or recruiters
Write private, contextual notes while the information is still fresh
Immediately find profiles you've already evaluated during your next visits

LeadCull is for professionals who use LinkedIn for prospecting, recruiting, or networking, and who want to reduce the mental load of remembering the people they meet.

It is not an automated prospecting tool. It is not a CRM.

It is a cognitive buffer: a lightweight space to capture your judgments, structure your thinking, and decide later, without interrupting your flow.

Cognitive buffer: an intermediate space that allows you to temporarily outsource your memory and impressions in order to reduce mental load and avoid losing important information while browsing.
