What we cast for
Every video is different, but most fall into one of three formats. You'll tell us which ones you're open to.
Follow one protocol, measured before and after. Coached throughout, often remote.
A full program, documented from day one to the final reveal.
Appear as a subject or example in a video. Usually in person.
How it works
One application, kept on file. We go back to the pool every time a new video is in the works.
About 3 minutes. Which videos you're open to, a bit about you, and how to reach you.
Each video has its own requirements. We look through applicants whenever a new one is being planned.
By text or email, to set up a short call and confirm details.
Apply once. Stay in the pool.
All experience levels. Built With Science+ members get priority.
