531 Social is a social selling system designed to help sales teams build consistent, human-led LinkedIn prospecting habits. Its 5-3-1 playbook guides each rep to focus daily on five target accounts, three key people at each company, and one meaningful action for each person. Rather than relying on random outreach, reps receive tailored tasks, coaching, and follow-up sequences to help them engage thoughtfully and move prospects through the sales process.

The platform includes account and contact management, prospect research and company signals, daily task lists, sequence planning, and a conversational coach that can suggest or draft posts, messages, and follow-ups. Teams can share their ideal customer profile, messaging, and case studies in a searchable library. Admins can import accounts, assign them to reps, and monitor activity and completion through dashboards and weekly views.

531 Social emphasizes user control and authentic engagement: it does not scrape data, automate messages, or send activity without approval. Team plans are priced per seat, with an individual plan also available.
