What is Grain?
Meeting recorder bets on MCP and one-click handoff to Claude and ChatGPT as its primary AI bridge.
Grain is shipping fast across three fronts at once. The newest grab-bag adds meeting-detection notifications, refreshed playlists, and tighter HubSpot sync. A major mid-May release introduced an MCP integration, one-click hand-off of meetings to Claude or ChatGPT, Markdown-formatted transcripts that include participant and prior-context, bulk send-to-AI actions, and Personal API access on the Starter tier. Earlier in the quarter, the desktop app gained a real-time notepad and a redesigned meeting page.
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.

Grain
6.3COMMS
Meeting recorder bets on MCP and one-click handoff to Claude and ChatGPT as its primary AI bridge.
◆ Current state
Grain is shipping fast across three fronts at once. The newest grab-bag adds meeting-detection notifications, refreshed playlists, and tighter HubSpot sync. A major mid-May release introduced an MCP integration, one-click hand-off of meetings to Claude or ChatGPT, Markdown-formatted transcripts that include participant and prior-context, bulk send-to-AI actions, and Personal API access on the Starter tier. Earlier in the quarter, the desktop app gained a real-time notepad and a redesigned meeting page.
◆ Where it's heading
Grain is rebuilding itself as the AI-friendly meeting layer rather than a standalone meeting tool. The MCP integration plus the deliberate work on AI-readable transcripts (Markdown, contextual metadata, bulk transport) signal that the product team thinks the user's value is increasingly created inside Claude/ChatGPT, not inside Grain itself. The live-meeting notepad and the API additions point in the same direction — make meeting data easy to extract.
◆ Prediction
Next likely moves are deeper MCP surface area (more action types, write-back into Grain from external agents), agent-driven workflows in HubSpot/Salesforce/Zapier integrations, and continued infrastructure work to make transcripts more queryable.
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.
