Blockit AI

AI-powered autonomous scheduling and negotiation platform

Overview

Blockit AI provides an AI-powered executive assistant that automatically coordinates meetings by using autonomous agents that negotiate times across calendars. It integrates with Google and Outlook calendars and can operate through email threads or Slack, learning a user’s preferences with natural language processing to improve scheduling. Unlike static scheduling links, its agents engage in dynamic, context-aware dialogue to find and lock in optimal slots across time zones and groups. Its goal is to reduce back-and-forth communications and free users to focus on higher-priority work, offered on a subscription basis (individual and multi-user team plans).

Simplify's take

What believers are saying

  • Blockit raised $5 million on January 22, 2026, led by Sequoia.
  • More than 200 companies use Blockit, including Brex, a16z, Accel, and Index.
  • Sequoia’s 2026 endorsement signals distribution leverage and a credible path to enterprise expansion.

What critics are saying

  • Calendly still dominates scheduling; Blockit must displace a familiar workflow by 2027.
  • Blockit’s pricing, $1,000 yearly individual and $5,000 team, blocks broad adoption after trials.
  • If agent-to-agent scheduling disappoints, customers revert to email and Slack, killing network effects.

What makes Blockit AI unique

  • January 2026 Blockit agents negotiate directly between calendars, unlike Calendly’s static links.
  • Kais Khimji and John Han bring Sequoia, Google Calendar, Timeful, and Clockwise experience.
  • Sequoia’s November 2026 company page calls Blockit the first AI scheduling agent understanding time.

Sequoia leads $5m seed round for AI calendar startup Blockit

Sequoia leads $5m seed round for AI calendar startup Blockit. Former Sequoia partner Kais Khimji has launched an AI-powered calendar scheduling startup called Blockit, which aims to automate meeting arrangements. The company, which recently closed a US$5 million seed round led by Sequoia, plans to use large language models to handle scheduling more effectively than previous solutions. Unlike platforms like Calendly, Blockit's AI agents communicate directly between users' calendars to negotiate meeting times without human involvement. The system can be activated via email or Slack, and it learns user preferences to prioritize meetings based on tone and importance. Blockit is currently used by over 200 companies, including Brex and Rogo, and offers a free 30-day trial. How would you feel if you could no longer use Tech in Asia?
