Sam Altman’s iris-scanning, identify-verification technology startup says it will begin expanding to the US starting May 1 and will launch a phone-like hardware device by next year. Those changes—and a promised World-branded debit card—signal the company’s ambitions to develop a “super app”—a goal shared by Elon Musk. Altman and Alex Blania, a German physics researcher, announced at an event in San Francisco Wednesday evening that their venture-backed company, Tools for Humanity, is updating its “World” products to include a new, smaller, eye-scanning orb. So the World app, and its hardware component, are Altman’s solution to the problem. “Proving personhood” is a hard thing to productize, and whiffs of a scam have plagued the startup since it launched.
