Blockit’s AI Agents Are Here to Hack Your Calendar—And Sequoia Just Backed Them

A former Sequoia Capital partner is betting $5 million that AI can finally fix the chaos of scheduling meetings—without humans touching a single email.

Kais Khimji, former Sequoia Capital partner, launched Blockit, an AI calendar-scheduling startup, after a decade of development. Sequoia led a $5 million seed round in Blockit, with GP Pat Grady calling it a potential '$1Bn+ revenue business'. Blockit uses AI agents to negotiate meeting times directly between users, bypassing email chains and competing with Calendly ($3B valuation).

"It always felt very odd... our databases just can’t talk to each other," said Khimji on calendar disconnection. Blockit’s AI agents prioritize meetings based on user preferences (e.g., skipping lunch) and email tone (e.g., 'Best regards' vs. 'Cheers').

"Blockit has a chance to become a $1Bn+ revenue business," wrote Sequoia’s Pat Grady. Blockit’s $1K/year pricing contrasts with Calendly’s $3B valuation, highlighting the risk of competing against an established leader. Khimji’s quote about calendar databases 'not talking' frames the problem Blockit aims to solve.
