# Blockit AI

> Blockit AI is a San Francisco startup building an AI scheduling agent that runs your calendar for you. You cc it on an email or ping it in Slack, and it books, reschedules, and negotiates meetings autonomously - learning which meetings are movable and which are not. When two Blockit users need to meet, their agents talk to each other directly, skipping the human back-and-forth. Founded by former Sequoia partner Kais Khimji and calendar veteran John Han, the company raised a $5M seed round led by Sequoia in January 2026 and says it has coordinated more than 100,000 meetings across 200+ companies.
