NYC publicist building story-first press intelligence platform

The Idea
PressLens is a story-first press intelligence platform for small businesses. Most PR tools make you search for a reporter and figure out the pitch yourself. PressLens flips it: a founder inputs their business URL, the platform finds their story, identifies journalists already covering companies like theirs, and tells them exactly what angle to use to get covered.

Who It's For
Small businesses that want press coverage but can't afford a full-service publicist or don't know how to navigate media outreach on their own.

What's Built
Initial site developed, waitlist live. Five weeks in.

Early Traction
Waitlist live.

Their Background
10 years as a publicist and agency owner. Worked at Endeavor (WME) before founding Possible PR in 2024. PR Net Next Gen Award recipient, recognized as one of the next generation of PR leaders.

What They Need
A product engineer to own the technical infrastructure and build alongside her. Preference for someone NYC-based. Looking for someone who ships fast and thinks about user experience as much as the code.
