One partner

From visibility to conversation.

You should not need five different providers to build your presence, publish useful content and start conversations with potential clients. Jennavi brings LinkedIn positioning, founder-led content, targeted outreach and reporting into one connected service, with additional long-form content support available through the Executive offering.

  • A ghostwriter to create the posts, who may never see what your outreach says.
  • A positioning specialist to fix a profile that does not convert.
  • Someone to research prospects and manage outreach.
  • An engagement solution for comments and follow-up.
  • A newsletter writer and an SEO writer for your website.
  • Someone to track conversations, leads and results.

Each can be good on its own. Coordinating them takes time, the work drifts apart, and a warm reply can sit unanswered. Jennavi tracks every reply in a CRM and hands you interested prospects with a suggested reply, so no conversation is lost. With Jennavi these jobs inform one another: one strategy, one consistent voice, one team that understands what you are building. See how Jennavi works and compare the packages on the pricing page.
