What is Gumloop?
Gumloop's agent triggers pick up the generic case: any webhook can start a run.
Gumloop builds AI agents and workflows for internal operations. Agents can now be started by a webhook, each with its own URL, so a form submission or an alert from another system kicks off a run carrying its payload — and an agent can be asked to set one up in chat. GLM 5.3 Flash joins the model list, and the release fixes agent chats stalling mid-task and losing work when resumed after an approval.
What is Postscript?
Postscript is handing SMS marketing to an agent that decides each subscriber's next message
Postscript is an SMS and RCS platform for Shopify merchants, and this archive shows it working two fronts at once. On acquisition it has multiplied the places a subscriber can opt in — embedded forms droppable on any page, standalone landing pages built on the popup editor, and Onsite Opt-in at Shoptin checkout. On messaging it is building Shopper, a conversational AI layer that now answers, analyses and increasingly initiates. The feed carries no publication dates, so this is an archive rather than a timeline.

Gumloop

Gumloop's agent triggers pick up the generic case: any webhook can start a run.
◆ Current state
Gumloop builds AI agents and workflows for internal operations. Agents can now be started by a webhook, each with its own URL, so a form submission or an alert from another system kicks off a run carrying its payload — and an agent can be asked to set one up in chat. GLM 5.3 Flash joins the model list, and the release fixes agent chats stalling mid-task and losing work when resumed after an approval.
◆ Where it's heading
This completes a trigger family that has been filling in for months: Outlook mail and calendar in August, Monday.com board activity a week later, and now the generic webhook that covers everything without a purpose-built connector. The reliability fixes in the same release point at the same goal — unattended runs are only useful if they finish. Agent management is also getting more self-service, with activity shown per agent and evaluation criteria pausable.
◆ Prediction
With a generic inbound trigger in place, the remaining gap is what happens when an unattended run needs a decision, so expect more work on approvals and on recovering runs that stall mid-task.

Postscript is handing SMS marketing to an agent that decides each subscriber's next message
◆ Current state
Postscript is an SMS and RCS platform for Shopify merchants, and this archive shows it working two fronts at once. On acquisition it has multiplied the places a subscriber can opt in — embedded forms droppable on any page, standalone landing pages built on the popup editor, and Onsite Opt-in at Shoptin checkout. On messaging it is building Shopper, a conversational AI layer that now answers, analyses and increasingly initiates. The feed carries no publication dates, so this is an archive rather than a timeline.
◆ Where it's heading
The centre of gravity is shifting from campaign tooling to per-subscriber decisioning. Shopper began as a responder, then gained a research surface over its own conversations, and now decides send timing and content for each individual. Alongside that, RCS is the delivery-side bet: webviews, dynamic product photos and tappable suggested replies all work to make the message thread the destination rather than a pointer to the storefront. Experimentation is being pushed into more of the journey rather than confined to campaign sends.
◆ Prediction
Expect the remaining hand-built primitives — static flows and manual segments — to be folded into Shopper's decisioning, and each new RCS capability to keep shipping with an automatic MMS or browser fallback so merchants can adopt it without maintaining a second path.
