We help fast-moving companies move contracts through legal at record speed, with transparency, predictable pricing, and exceptional quality.
We are hiring a Founding Content & Social to own how the world hears about us. You will capture, write, edit, film, and publish all of our content to turn our company and team into the most recognizable voices in startup legal.

Define the voice of a generational law firm before anyone else does
Own social, video, and brand content end to end
Ghostwrite for team members whose audiences you will grow from the ground up
Build the content engine that turns demand into qualified meetings
Own meaningful equity in a company with category-defining ambition
Take on responsibility far beyond your years of experience

Amplify every launch, event, and conference
Measure everything and kill what isn't working, with a weekly report on what performed and what changes because of it

You can make a clean graphic or carousel in Figma, Canva, or ChatGPT
You can shoot decent video on a phone and cut it in CapCut, Premiere, or Descript

Day 60: You own a repeatable content engine and continuously amplify and scale it
2-4 years creating content at a startup, agency, or for a creator; bonus if you’ve ran a content agency

You are relentless, and will work 12+ hours per day, 6 days a week (yes, including weekends)
You thrive in an environment with an exceptionally high bar, where everyone is expected to go above and beyond
You own outcomes from start to finish and have a track record of never dropping the ball
