In summary:

Supergrow and Postbeam both run LinkedIn content for several people, with different goals at the end. Supergrow interviews executives and experts, keeps a Content DNA profile for each, and moves drafts through review before scheduling. Postbeam drafts with its AI, Marv, or through Claude, ChatGPT and Gemini, schedules across connected accounts, shares approval links with reviewers who have no account, and captures people who engage as warm leads. The choice comes down to expert voices and program participation versus social selling and lead capture.

Interviews + Content DNA

A skeptical CTO approved his first drafts without a single edit

12 leaders posting consistently in the first month

“We'd been trying to launch an employee advocacy program for two years. Everyone agreed it mattered, but no one had time. Supergrow got 12 of our leaders posting consistently within the first month.”

Content Board

Eight accounts, one view of every draft

Challenges

40+ team members posting regularly

“Getting our sales and customer success teams to post on LinkedIn® felt impossible. Once we launched challenges with leaderboards, everything changed. Now over 40 team members are posting regularly and actually competing for streaks.”
