Pros & cons of Blockit
Blockit's pitch is removing the back-and-forth of scheduling entirely: it negotiates over email and Slack, books once there's agreement, and rebooks itself if something changes. Pricing jumps quickly from a free tier past a near-$1,000-a-year Lite plan to a near-$5,000-a-year Infinity plan, so casual users have a real gap to cross to reach the tiers that unlock the full agent behavior.
Pros
- Negotiates meeting times directly over email and Slack rather than just sharing a booking link
- Automatically handles time-zone conflicts and rebooking when plans change
- Founded by people with real venture and operating backgrounds, including an ex-Sequoia partner
- 30-day trial with no card required before any payment
Cons
- Paid tiers jump from free to $999/year (Lite) with a steep gap between them
- Enterprise tier pricing starts around $20,000/year and requires custom negotiation
- An agent negotiating on someone's behalf needs oversight to avoid scheduling mistakes
Best for
- Executives and founders drowning in scheduling back-and-forth over email and Slack
- VC firms and startups that already move fast and want scheduling automated end to end
- Teams comfortable paying an annual fee for an assistant-style tool
Not for
- Individuals who only schedule occasionally and don't need an active negotiating agent
- Budget-conscious users unwilling to jump from free to a near-$1,000/year plan
