Two AI built networks, pointed in different directions
Both companies collect people by talking to them with AI. micro1's Zara interviews applicants, certifies their skills, and puts the ones who pass to work on micro1's projects for AI labs and government. A company buying from micro1 receives the output of that work, not the people.
Jack talks to job seekers about their goals, pay and trade offs, and candidates opt in when they are ready to move. Jill then matches a company's brief against those conversations. Jack and Jill says Jill never cold messages strangers; every introduction is to someone who has already agreed to talk.
