What is Calendly?
Calendly turns scheduling into a commerce surface and lands inside Claude.
Calendly is shipping along two clear threads. First, payments and commerce: Meeting Packages let users sell multi-session bundles up front, and Payment Links move money outside the booking flow entirely. Second, AI distribution: a Claude Connector and a Calendly MCP server make scheduling actionable from inside conversational AI tools. Contact Lists and Custom Fields plug a long-standing gap by adding lightweight CRM capabilities. The recent feed has noticeable duplicate ingest, with several entries appearing twice across consecutive days.
What is Superhuman?
Superhuman bets on agent-operable email: a Codex plugin now drives the inbox.
Superhuman is pushing two threads: making the inbox drivable by AI agents, and refining its Split Inbox system. The newest move is a Codex plugin, built on its MCP, that lets Codex, Claude, and ChatGPT search, draft, triage, and act on mail using Superhuman-native primitives like Split Inbox and read statuses. Around it sit steady Split Inbox and mobile UX improvements.

Calendly
5.0COMMS
Calendly turns scheduling into a commerce surface and lands inside Claude.
◆ Current state
Calendly is shipping along two clear threads. First, payments and commerce: Meeting Packages let users sell multi-session bundles up front, and Payment Links move money outside the booking flow entirely. Second, AI distribution: a Claude Connector and a Calendly MCP server make scheduling actionable from inside conversational AI tools. Contact Lists and Custom Fields plug a long-standing gap by adding lightweight CRM capabilities. The recent feed has noticeable duplicate ingest, with several entries appearing twice across consecutive days.
◆ Where it's heading
The product is widening from 'time-booking utility' into a commerce-and-relationships surface for service providers. Meeting Packages give coaches and consultants a way to sell engagements without a separate billing tool; Custom Fields turn contacts into mini-records. Pairing this with conversational-AI distribution (Claude, ChatGPT via MCP) bets that 'book a meeting' will increasingly be invoked from outside the Calendly UI.
◆ Prediction
Expect more Stripe-powered commerce primitives — recurring sessions, post-meeting invoicing, refund flows. The CRM thread will likely deepen with notes and activity timelines on contact records. AI distribution will spread to additional MCP-aware assistants and into Calendly's own Workflows.
Superhuman
6.3COMMS
Superhuman bets on agent-operable email: a Codex plugin now drives the inbox.
◆ Current state
Superhuman is pushing two threads: making the inbox drivable by AI agents, and refining its Split Inbox system. The newest move is a Codex plugin, built on its MCP, that lets Codex, Claude, and ChatGPT search, draft, triage, and act on mail using Superhuman-native primitives like Split Inbox and read statuses. Around it sit steady Split Inbox and mobile UX improvements.
◆ Where it's heading
Superhuman is positioning itself as the email client AI agents operate, not just one humans use — its MCP, Draft Sync with Gmail and Outlook, and now a Codex plugin all point the same way. In parallel it keeps sharpening Split Inbox (reorder, hide-empty, a Reminders split) and mobile flow. The bet is agent-operability plus opinionated triage as the wedge against Gmail and Outlook.
◆ Prediction
Expect more agent surface — additional MCP hosts and agent-drivable actions — alongside continued Split Inbox personalization. The entries point to agentic email as the primary investment line.
