“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.”

Tradespace 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.” Content drove 70% of their leads as they 3x’ed revenue, 5x’ed customers, and landed their Series A.

Infera, an AI compliance platform for medical device teams, needed to build trust before it had many customer logos to point to publicly.
We started with a six-article thought leadership series for the CEO, built on in-depth research into FDA data and recall studies, plus interviews with the CEO and the company’s Head of Regulatory, a former FDA reviewer. The series tied quality to the bigger picture: as AI changes how medical devices are built, quality has to be designed in from the start.
The series became the company narrative, driving the CEO’s LinkedIn, the newsletter, conference media and a gated ebook.
From Q1 to Q3, blog views grew nearly 4x, traffic from the CEO’s LinkedIn posts doubled, and LinkedIn engagement rose 55%.

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.
