What is Customer.io?

Customer.io spent the summer pushing messaging off the screen and into location, time, and the lock screen

The summer release cycle put more than ten features into the product, and the coherent ones are about context rather than content: geofences trigger workflows when someone enters or leaves a physical location, live notifications render as iOS Live Activities and Android Live Updates, date triggers now read attributes on custom objects, and a notification inbox retains pushes. Around that sits infrastructure work — SMS via Sinch, Infobip and Vonage, multiple mobile apps per platform in one workspace, send-rate controls on automations — and an LLM actions surface where knowledge sources can be attached once and reused across prompts. The most recent entry is editor ergonomics in Design Studio.

What is Gumloop?

Gumloop 13.1 lets live artifacts drive agents through the SDK and opens outputs in Office.

Gumloop ships a numbered release every few days. In October it gave agents a real browser (12.0), agent-owned secrets, team sharing and embeddable AI artifacts, then 13.0 rebuilt the agent harness for longer work and added organization-wide evaluations. 13.1 lets scripts in live artifacts message, create and list agents, artifacts, skills and teams through the Gumloop SDK, opens agent-made files in Google Workspace or Microsoft Office, and lets agents on a call run long tasks in the background while they keep talking.

◆ Current state

The summer release cycle put more than ten features into the product, and the coherent ones are about context rather than content: geofences trigger workflows when someone enters or leaves a physical location, live notifications render as iOS Live Activities and Android Live Updates, date triggers now read attributes on custom objects, and a notification inbox retains pushes. Around that sits infrastructure work — SMS via Sinch, Infobip and Vonage, multiple mobile apps per platform in one workspace, send-rate controls on automations — and an LLM actions surface where knowledge sources can be attached once and reused across prompts. The most recent entry is editor ergonomics in Design Studio.

◆ Where it's heading

The platform is expanding the set of things that can start a message and the set of places one can land, which is a different axis from the segmentation-and-copy tooling most of this category competes on. Geofences and live notifications both take work that previously required a specialist vendor or custom device code and make it a workflow primitive. The LLM actions work is following the same instinct — reusable knowledge sources are the beginning of prompt infrastructure rather than a prompt box — but it is the least developed of the threads. Meanwhile send-rate control and multi-app support read as enterprise deployment blockers being cleared.

◆ Prediction

Expect the location and live notification surfaces to gain the operational controls that continuous device features require, and the LLM actions path to keep accreting reusable pieces. Design Studio is receiving steady editor polish, so a broader component authoring release is plausible.

Gumloop 13.1 lets live artifacts drive agents through the SDK and opens outputs in Office.

◆ Current state

Gumloop ships a numbered release every few days. In October it gave agents a real browser (12.0), agent-owned secrets, team sharing and embeddable AI artifacts, then 13.0 rebuilt the agent harness for longer work and added organization-wide evaluations. 13.1 lets scripts in live artifacts message, create and list agents, artifacts, skills and teams through the Gumloop SDK, opens agent-made files in Google Workspace or Microsoft Office, and lets agents on a call run long tasks in the background while they keep talking.

◆ Where it's heading

The product is moving from building agents to operating them at org scale, and artifacts are turning into small apps that can control agents themselves. Model access is also being made easier to manage, with families, deprecation dates and fallback visibility.

◆ Prediction

Expect more of the SDK exposed to artifacts and further evaluation and Insights controls at the usual weekly pace; the entries don't show pricing changes.
