The more complex your work, the harder it is to communicate.

I help executives turn industry expertise into stories worth telling, through:

Clarity

Bridge the gap between your knowledge, their understanding, and the blank page.

Clarity

Meet your customers where they are, speak their language not yours

Consistency

Make showing up the main barrier to posting — we handle the heavy lifting.

“I can brain dump on Jess and from there she’s able to find the story and decipher it into writing that’s compelling. Working with her is a hell of a lot faster and better than what I could make on my own.”

Case Study

AI startup Tradespace's audience of IP attorneys is both highly sophisticated and skeptical of AI, so generic content wasn't going to cut it. Only rigorous thought leadership would do.


We began by writing a whitepaper that didn't aim to sell, but instead mapped the business, legal, and technology forces reshaping IP to give Tradespace credibility pre-sales.


From there, we built out the exec team's LinkedIn presence, newsletters, and blogs, plus website copy, emails, and case studies.


Tradespace loves that we "make IP sound sexy." In one year, they 3x'ed revenue, 5x'ed customers, and landed their Series A.

About

Jess Sun’s “why” is to build understanding — something she got a lot of practice at as the daughter of immigrants, one a free spirit and one an engineer.


Tech is how her family’s life changed, so she’s long been a believer. But she quickly learned that in the real world, change doesn’t just happen on its own: emerging tech must be sold. She’s been exploring that concept firsthand ever since.


Independent since 2020, Jess has spent 15+ years making big ideas feel accessible across AI, B2B services, and beyond. She began her career leading internal comms for Target's multichannel transformation and holds an MBA from UC Berkeley Haas. Learn more about her on LinkedIn.
