This is a junior role designed for someone who lives and breathes crypto Twitter, moves quickly, thinks clearly, and wants deep exposure to how leading founders and teams build influence, distribution, and narrative in the space.

You’ll be responsible for monitoring crypto Twitter seven days a week, identifying emerging narratives, technical discussions, and high-signal posts from prominent founders, researchers, and intellectuals.

You’ll share concise, high-quality updates with the team and, over time, help draft original content that engages directly with what’s happening online.

This role also supports broader marketing efforts, including event and conference submissions, and plays a key role in supporting the founder’s personal brand.

• Support the founder’s personal brand by helping surface ideas, trends, and content opportunities

• Assist with general marketing initiatives, including:

  • Event, conference, and community submissions

  • Research and coordination around ecosystem opportunities

• Prior experience supporting founders, creators, or personal brands

This role is best suited for someone who
