While much of the world is wringing its hands over how AI might replace people, one startup wants to prove that the real opportunity lies in bringing the two together. Launched earlier this year, Kartel is a creative marketplace that helps brands and agencies create campaigns by matching them with freelance artists who specialize in AI. That vision is already playing out for Laser Eye Center, a Los Angeles-based company specializing in Lasik that started experimenting with Kartel to generate creative for broadcast television.
