Abdul Jamjoom

Abdul Jamjoom is the co-founder and CEO of Arini, a San Francisco startup building an AI receptionist that answers phones, books appointments, and handles patient communication for dental practices around the clock. A Harvard computer science graduate and former search and applied-AI engineer at the enterprise messaging company Threads, he teamed up with his high-school friend Rami Rustom - the pair met in Jordan - to attack a market they found by literally walking into dental offices and watching front desks melt down. Backed by Y Combinator (W24), Arini turns the $7B-a-year dental front-desk problem into software that, in Jamjoom's words, just gets the job done.
