Article Summary

Kais Khimji, a seasoned venture investor with six years at Sequoia Capital, is embarking on a new venture with Blockit, an AI calendar scheduling application. The startup leverages the latest advancements in Large Language Models (LLMs) to tackle the frustrating and time-consuming task of coordinating meetings. Unlike existing solutions, Blockit’s AI agents can handle the entire scheduling process without human intervention, learning user preferences and even adapting to nuances like preferred meeting tones. The company’s approach centers around creating a ‘context graph’ by understanding the 'why' behind scheduling requests – a concept championed by investors like Jaya Gupta and Ashu Garg at Foundation Capital. Blockit’s technology allows users to simply copy and paste the AI agent into an email or messaging app, enabling it to negotiate meeting times and locations based on specified needs. Early traction includes adoption by over 200 companies, including AI startup Together.ai, fintech firm Brex, and robotics company Rogo, alongside prominent venture capital firms such as a16z and Accel. The application is offered initially for free for 30 days, transitioning to a $1,000 annual fee for individual users and a $5,000 team license. This move underscores the growing trend of leveraging LLMs to automate complex workflows and unlock new efficiencies in business operations.

Key Points

  • Kais Khimji, a former Sequoia Capital partner, is founding Blockit, an AI calendar scheduling company.
  • Blockit utilizes Large Language Models (LLMs) to automate meeting arrangements, bypassing the traditional back-and-forth of scheduling.
  • The company's approach emphasizes building ‘context graphs’ by understanding the underlying reasons behind scheduling requests, a strategy advocated by Foundation Capital investors.

Why It Matters

The rise of Blockit represents a significant development in the application of AI to a ubiquitous, yet surprisingly complex, business task. The potential impact extends beyond simple calendar management; it signifies a broader shift towards AI agents that can understand and respond to the ‘why’ behind business decisions – a critical element missing from many current automation tools. This news is particularly relevant to professionals involved in operations, sales, and project management, demonstrating a practical application of cutting-edge AI and the increasing capability of LLMs to handle nuanced, real-world scenarios. The backing by Sequoia Capital further validates the technology's potential, signaling a renewed focus on AI-driven efficiency.
