What is Superhuman?
Inbox becomes an MCP endpoint — agents now drive Superhuman alongside humans, in your voice.
Superhuman ships at very high cadence, mixing mobile polish (Quick Reply from notifications, calendar widget, Split Inbox reorder/hide) with category-shifting AI work. The April MCP launch turned Superhuman Mail into a callable surface for Claude, ChatGPT, and other assistants, with 'uniquely Superhuman' actions (Smart Send, Read Statuses, Split Inbox triage) exposed as tools. Draft Sync with Gmail/Outlook bridges the agent ecosystem further: assistants can draft anywhere, you review and send in Superhuman.
What is Heymarket?
Heymarket evolves from team SMS into an AI-agent messaging platform.
Heymarket has shipped a string of real product features — Escalations, inbound webhooks, Conversation Tags, Salesforce/HubSpot email — and is now publicly building AI agents that handle customer messaging, with the team using its own product as the first deployment site. The platform is moving past 'business texting' into multichannel customer messaging with structured workflows and automation primitives.

Superhuman
6.3COMMS
Inbox becomes an MCP endpoint — agents now drive Superhuman alongside humans, in your voice.
◆ Current state
Superhuman ships at very high cadence, mixing mobile polish (Quick Reply from notifications, calendar widget, Split Inbox reorder/hide) with category-shifting AI work. The April MCP launch turned Superhuman Mail into a callable surface for Claude, ChatGPT, and other assistants, with 'uniquely Superhuman' actions (Smart Send, Read Statuses, Split Inbox triage) exposed as tools. Draft Sync with Gmail/Outlook bridges the agent ecosystem further: assistants can draft anywhere, you review and send in Superhuman.
◆ Where it's heading
The product is moving from 'fast email for power users' to 'AI-and-humans share the inbox.' Personalization, Write with Voice, and MCP form a clear stack — voice in, agent action, voice out — with the original power-user keyboard-shortcut audience preserved through continued Split Inbox refinement. Mobile gets weekly polish to keep that surface from rotting while the AI direction takes the headlines.
◆ Prediction
Next likely move is delegated-inbox MCP actions for executive assistants (act-as-on-behalf permissions) and recurring agent tasks tied to Personalization rules. A cross-app demo — Superhuman + Granola + a calendar tool, all via MCP — is the obvious narrative the May 21st virtual event has been set up to deliver.
Heymarket
6.3COMMS
Heymarket evolves from team SMS into an AI-agent messaging platform.
◆ Current state
Heymarket has shipped a string of real product features — Escalations, inbound webhooks, Conversation Tags, Salesforce/HubSpot email — and is now publicly building AI agents that handle customer messaging, with the team using its own product as the first deployment site. The platform is moving past 'business texting' into multichannel customer messaging with structured workflows and automation primitives.
◆ Where it's heading
Each release stacks toward a coherent thesis: omnichannel inbox plus tagging plus escalation routing plus webhooks adds up to the platform substrate an AI agent needs. The 'eating our own dogfood' post on AI agents confirms agents are now in production internally, which is a stronger signal than a marketing launch. Heymarket is positioning to be where SMBs run customer messaging end-to-end, with humans handling exceptions the agents escalate.
◆ Prediction
Expect a public-facing AI agents launch in the next quarter — likely a packaged product with deflection rate or response-time SLAs as the headline metric. Pricing change toward usage-based components (per-resolution or per-conversation) would be the natural follow-on as agent costs become the dominant unit economics question.
