Blockit

Time is the most valuable resource we have, yet coordinating it is still stuck in the dark ages. At Blockit, we're building the AI that finally fixes this: an autonomous time agent that handles the full complexity of scheduling — timezones, group coordination, in-person logistics — like an executive assistant that never sleeps.

Every LLM application to date has been a one-on-one conversation (ChatGPT, Claude, Perplexity). Blockit is one of the first multiplayer, stateful AI agents — coordinating between multiple people, maintaining context across conversations, and taking real actions in the world. The more people connect their calendars, the more powerful our network becomes. This is the foundation of a platform of AI agents with access to the world's time.

We're Series A, backed by Sequoia, and a small, sharp team that moves fast, ships constantly, and holds a high bar.
