What is Gumloop?
Gumloop is building the enterprise floor under an agent it now ships pre-assembled
Gumloop's window splits cleanly in two. On one side is Gumball, its first agent customers do not have to build, arriving with standing jobs — a morning briefing, meeting prep, and an inbox that sorts and drafts. On the other is the administrative apparatus an enterprise buyer demands: managed tunnels to private MCP servers, model access by role, approval routing, bring-your-own Fireworks keys, and GitHub-synced skill libraries.
What is Litmus?
Litmus is publishing deliverability practitioner content, not shipping product
The window is entirely editorial and weighted toward deliverability and lifecycle craft: protecting a sending domain through a rebrand, promoting preference centres to lift opt-in quality, birthday email mechanics, a deliverability primer, and a summer prep guide for the holiday sending season. Two shorter posts on e-receipts and email anatomy round it out. Publishing runs every few days with no release notes among them.

◆ Current state
Gumloop's window splits cleanly in two. On one side is Gumball, its first agent customers do not have to build, arriving with standing jobs — a morning briefing, meeting prep, and an inbox that sorts and drafts. On the other is the administrative apparatus an enterprise buyer demands: managed tunnels to private MCP servers, model access by role, approval routing, bring-your-own Fireworks keys, and GitHub-synced skill libraries.
◆ Where it's heading
Connector expansion continues at a steady clip — Azure, Meta Ads, DataForSEO, Sprout Social, SharePoint, NotebookLM, Zendesk, Gong — but it is no longer the story. The center of gravity has moved to who may use which model, where agents may reach, and who approves it, which is the vocabulary of a platform being bought by organizations rather than adopted by individuals. Distribution is moving the same direction, with agents pushed into Slack workspaces and reachable by people who have no Gumloop account.
◆ Prediction
Expect Gumball to graduate from beta with more standing jobs attached to the connectors already in the catalog, and expect the governance surface to keep thickening around it — audit and spend controls are the obvious gaps next to the role and approval work already shipped. The Outlook parity push suggests Microsoft-side coverage will continue to close against the Google-side features.

Litmus is publishing deliverability practitioner content, not shipping product
◆ Current state
The window is entirely editorial and weighted toward deliverability and lifecycle craft: protecting a sending domain through a rebrand, promoting preference centres to lift opt-in quality, birthday email mechanics, a deliverability primer, and a summer prep guide for the holiday sending season. Two shorter posts on e-receipts and email anatomy round it out. Publishing runs every few days with no release notes among them.
◆ Where it's heading
The consistent thread is sender reputation as the thing that actually determines email program performance — domain handling during a rebrand, consent quality via preference centres, and seasonal warm-up before Black Friday all sit on that axis. That is the ground Litmus's testing and monitoring products occupy, so the content maps to the product's value even though it never mentions a change to it.
◆ Prediction
Expect more seasonal deliverability content as the holiday sending window approaches. Product signal is not available from this feed and would require the release notes instead.
