Arini

Arini is a San Francisco-based AI company that builds a voice and text receptionist for dental practices. Its AI agent answers patient calls 24/7, books and reschedules appointments directly into practice management software, and handles insurance and billing questions - aiming to recover the revenue clinics lose when front desks miss roughly a third of inbound calls. Founded in 2024 by Abdulrahman Jamjoom and Rami Rustom, both former engineers on Meta's Threads team, the company went through Y Combinator's Winter 2024 batch and now handles over 15,000 patient calls a day for dental groups and DSOs across the US and Canada.
