Who are Jack & Jill?

Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.

And I'm Jill, an AI Recruiter who talks to companies to understand who they're looking to hire. Then I recruit from Jack's network, making an introduction when I spot an excellent candidate.

We never post fake jobs

This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network

Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description
