Heymarket vs Slack
Side-by-side trajectory, velocity, and editorial themes.
Heymarket layers AI agents and routing on top of its business-messaging core.
Heymarket is a business-messaging platform expanding across channels (now RCS via Twilio) and into AI agents and workflow features like Escalations. The crawled feed mixes real feature announcements with how-to and thought-leadership content.
The product is moving from shared-inbox messaging toward AI-assisted, omnichannel operations — RCS, AI agents trained in-house, escalation routing, and structural tools like conversation tags and webhooks. The direction is a fuller customer-messaging operations layer.
Expect continued investment in AI agents and channel breadth (RCS, voice) on top of the shared-inbox foundation, likely with more routing and automation controls.
Slack is quietly rebuilding itself as a runtime for third-party agents.
Slack's developer platform has shifted its center of gravity from bots-that-reply to agents-that-act. The last month is dominated by agent primitives: apps can now receive the context a user is looking at, Slackbot can call external tools over MCP, and a dedicated agent messaging surface ships alongside steady CLI and Block Kit work.
Each release fills in a piece of an agent platform — context in, tools out, and a native place for agents to converse. Block Kit is gaining richer primitives (containers, data visualization) that read as the display layer for agent output. Three CLI releases in a month show the tooling keeping pace with the expanding surface.
Expect the next moves to connect these pieces: agent context feeding MCP tool calls, and Block Kit's new blocks becoming the standard way agents render results in-channel.
