OpenAI bought his startup; now he leads a AI product

Alexander Embiricos, a software engineer who spent five years building a collaboration platform called Multi, has transitioned from startup founder to leading AI products at OpenAI. Born from Co-founder Charley Ho's vision, Multi aimed to improve remote team collaboration through features like screen sharing, customizable shortcuts, and automatic linking of code, designs, and documents.

In 2024, OpenAI acquired Multi, marking an "acqui-hire" where most of the small team joined OpenAI. Following the acquisition, Embiricos became a product lead on Codex, OpenAI's AI coding assistant, before taking a broader product leadership role in October 2026. He now oversees Dots, an always-on personal AI agent designed to assist users with tasks and connect with their apps in the background.
