Substack & LinkedIn Authority Partnerships
Turn your expertise into influence with platforms built for visibility and trust.
Substack and LinkedIn are no longer just content hubs — they’re credibility platforms. We help entrepreneurs, executives, and experts transform these channels into engines for visibility, influence, and measurable growth.
Our comprehensive thought leadership approach integrates owned platforms with earned media — combining Substack, LinkedIn, and media bylines to build visibility, authority, and credibility across multiple channels.
Substack & Owned Newsletter Strategy
Substack and Branded Newsletter Approach
Owned newsletters are one of the fastest-growing authority assets — giving leaders direct access to their audience without gatekeepers or algorithms. Substack allows you to control your message, build a subscriber base, and support your PR and media efforts with consistent, high-value content.

-
Launch, structure, and develop your Substack newsletter.
-
Build your subscriber base with targeted list growth tactics.
-
Develop an ongoing content calendar aligned to your authority positioning and PR efforts.
-
Collaborate with relevant Substack creators, podcasts, and niche platforms to cross-promote visibility.
-
Integrate your newsletter into your larger visibility-building plan — ensuring it actively supports your earned media, interviews, speaking engagements, and business development.
