What is Customer.io?

Customer.io is widening what a journey can express and where its agent can be reached.

Two threads run side by side. The automation engine keeps gaining expressiveness: per-channel rate limits in early August, and now a Wait Until block that accepts multiple delays, time windows, and And/Or/nested condition groups. Separately the AI agent moved into Slack, while messaging reach grew with transactional WhatsApp and support for multiple mobile apps in one workspace.

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.

Customer.io vs Gumloop: editorial side-by-side

Customer.io is widening what a journey can express and where its agent can be reached.

◆ Current state

Two threads run side by side. The automation engine keeps gaining expressiveness: per-channel rate limits in early August, and now a Wait Until block that accepts multiple delays, time windows, and And/Or/nested condition groups. Separately the AI agent moved into Slack, while messaging reach grew with transactional WhatsApp and support for multiple mobile apps in one workspace.

◆ Where it's heading

The Wait Until change is the clearest read on where the builder is heading: logic that previously needed a chain of wait steps now collapses into one block, which makes journeys shorter and harder to misread. Paired with rate limits and the wait-before-continuing option, timing and pacing are becoming first-class controls rather than things you assemble from primitives. The agent work runs on a separate track, pushing the product into tools people already sit in.

◆ Prediction

Expect the nested And/Or condition model to spread from Wait Until into other branching actions, since the release describes grouping as a property of the path rather than of that single block.

7.5

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.
