Bio

Hi, I'm Ari, co-founder of Avenir AI (AI agents for HR/Benefits). I graduated MIT (Bachelor's and Master's), where I studied Computer Science and Cognitive Science. I previously built B2B AI products at Apple and Microsoft, including AI Experiences where Copilot was born. I researched in ML for Healthcare for 3 years at MIT's top AI labs: CSAIL and the Media Lab.
